1936 Dodge D2 Six: 218-Cubic-Inch Flathead and Steel Body

Dodge built the D2 passenger-car series for the 1936 model year around a 217.8-cubic-inch L-head six rated at 87 horsepower. It used a 116-inch wheelbase, a three-speed manual transmission, rear-wheel drive, four-wheel hydraulic brakes, and a separate steel frame beneath coupe, sedan, touring sedan, and convertible bodies.

Best known for combining Dodge's durable flathead-six powertrain with the fuller, more streamlined steel bodywork adopted during the middle of the 1930s, the D2 became one of the division's strongest pre-war sales successes. Commonly published production totals place 1936 Dodge passenger-car output at approximately 263,000 units, although surviving records do not always separate every D2 body style with equal consistency.

The D2 belongs to what collectors often describe broadly as the Pre-War Dodge Six era. It followed the 1935 DU series and preceded the 1937 D5, making it a single-model-year design rather than a long-running chassis generation. Its appeal now rests less on outright rarity than on mechanical accessibility, Art Deco detailing, broad body-style choice, and the unusually high survival value of complete, unmodified examples.

Quick Facts

The essential D2 specifications are straightforward, but body-style differences affect dimensions, weight, trim, and collector demand. The following table establishes the common mechanical foundation shared by the 1936 passenger-car range.

The D2 code identifies the complete 1936 passenger-car series, not a special performance derivative. Body style and completeness therefore matter at least as much as the series designation when assessing a surviving car.

Why the Dodge D2 Matters

The D2 arrived when American manufacturers were replacing upright, visibly separate body elements with lower rooflines, integrated luggage compartments, rounded fenders, and more disciplined airflow management. Dodge retained a conventional frame and familiar side-valve engine, but wrapped them in a visibly newer body with a tall vertical-bar grille, skirted rear bodywork, enclosed steel roof on closed cars, and headlamps mounted closely against the front fenders.

Its commercial result was substantial. Dodge moved well beyond its depressed early-1930s volumes and competed directly with Chevrolet's Standard and Master models, Ford's Model 68 V8, and its Chrysler stablemate, the Plymouth P2. Buyers received six-cylinder smoothness and hydraulic braking without moving into Chrysler's more expensive products.

The D2 also marks a useful dividing line for restorers. It retains exposed running boards, a beam front axle, separate fenders, mechanical simplicity, and traditional body-on-frame construction, yet its steel body and hydraulic controls make it less archaic to operate than many cars designed only a few years earlier.

Historical Context and Development

Dodge in the 1936 Market

Chrysler Corporation owned Dodge Brothers from 1928 onward, and by 1936 the division shared the corporation's emphasis on rationalized engineering, all-steel body construction, hydraulic brakes, and durable side-valve engines. Dodge was priced above Plymouth while remaining below most Chrysler-branded models. The distinction was expressed through wheelbase, finish, body size, and equipment rather than through an exotic mechanical specification.

The American market was recovering from the worst years of the Depression, but price and operating cost remained decisive. Ford promoted V8 power, while Chevrolet relied on overhead-valve six-cylinder engines and increasingly sophisticated independent front suspension in its higher series. Dodge answered with a larger-displacement flathead six, hydraulic braking, robust conventional suspension, and bodies designed for family use on roads that still ranged from paved highways to rutted rural tracks.

Body Design and Proportions

The D2's nose is defined by a narrow, gently convex grille filled with vertical bars. The hood sides carry horizontal ventilation openings, while the front fenders sweep rearward into full running boards. A split windscreen, tall greenhouse, and rear-hinged front doors preserve the visual grammar of the early 1930s even as the rounded roof and fuller rear quarters point toward the end of the decade.

Touring sedans incorporated an external-looking but body-integrated rear luggage compartment, giving them a longer, more formal profile than flat-back sedans. Coupes place the cabin well behind the front axle and carry a short roof over a substantial rear deck. Convertible bodies are particularly prized because their structural timber, top mechanisms, and model-specific trim are expensive to reconstruct when missing.

Motorsport and Homologation

The D2 was not developed as a homologation model, and Dodge did not create a factory competition version comparable to later stock-car specials. Its competition relevance lies primarily in the endurance reputation of Chrysler's flathead six and in private use of inexpensive American production cars in local hill climbs, reliability trials, and oval-track events. A competition history should be accepted only when supported by contemporary entries, photographs, timing records, or ownership documentation.

Engine and Drivetrain

The D2 used Dodge's water-cooled L-head inline six, commonly rounded to 218 cubic inches in modern descriptions. Its valves sit beside the cylinders within the block, operated by a camshaft through tappets. The detachable cylinder head contains no rocker gear, simplifying service but limiting breathing compared with an overhead-valve design.

A single downdraft carburetor supplies the engine through a conventional intake manifold. Ignition is by coil and distributor, using the six-volt electrical system typical of the period. A gear-driven oil pump provides pressure lubrication, while a belt-driven water pump, fan, radiator, and thermostat manage cooling.

Power passes through a dry single-plate clutch and three-speed manual gearbox to a propeller shaft and live rear axle. Synchromesh assists the upper forward ratios, but first gear should be treated as non-synchronized unless the specific gearbox has been verified otherwise. Rear axle ratios can differ with body, production specification, or later replacement, so an inspection should establish the fitted gearset rather than relying on a general reference figure.

The core factory dimensions explain the engine's long-stroke character. Torque and governed engine speed were not consistently presented in surviving general sales literature, so unsupported modern estimates are omitted.

The 4.375-inch stroke is the defining feature on the road. The engine is intended to pull from low speed rather than chase high revolutions, and correct ignition timing, carburetor calibration, valve clearance, and cooling-system condition matter more than attempts to extract modern-style acceleration.

Chassis, Suspension, and Braking

The D2 uses a separate steel frame beneath an all-steel passenger body. At the front, a forged beam axle is located by semi-elliptic leaf springs, while the live rear axle is likewise carried on longitudinal leaf springs. Hydraulic shock absorbers control movement, although worn links, bushings, shackles, and dampers can leave a restored-looking car markedly less composed than intended.

Steering is by a manual recirculating or worm-type steering gear acting through a conventional linkage. Four-wheel Lockheed-pattern hydraulic drum brakes were a meaningful Dodge advantage in an era when some competitors had only recently abandoned cable actuation. The system is effective when correctly adjusted, but it has no power assistance and depends on sound drums, properly arced linings, dry axle seals, and free wheel cylinders.

This table concentrates on dimensions and equipment that apply broadly across the D2 family. Body-specific measurements and weights should be checked against the appropriate factory body manual or sales sheet.

The straight front axle should not be confused with the independent front systems found on some contemporary Chrysler Corporation products. It gives the D2 durability and predictable geometry, but road shocks reach the steering more directly than they do in an independently sprung Chevrolet Master De Luxe.

Driving Experience and Handling Dynamics

A healthy D2 starts with a slow, deliberate churn from its six-volt starter, then settles into the muted mechanical rhythm characteristic of a long-stroke flathead. Throttle response is measured rather than sharp. The engine pulls cleanly at modest revolutions, and the driver makes the best progress by changing up early and preserving momentum.

The floor-mounted gear lever has a long throw, with a mechanical action that rewards unhurried shifts. Second and third are the working ratios on rolling roads. First is chiefly for moving away, steep grades, and very low-speed traffic, and an attempted hurried downshift can expose worn synchronizers or poor clutch adjustment.

At parking speed the steering is heavy, particularly if tire pressures are low or oversized modern tires have been fitted. Once moving, it lightens and provides clear directional information, although the beam axle reacts to potholes and ridges through the wheel. Body roll is evident, but sound springs and dampers keep it progressive rather than uncontrolled.

The drum brakes demand a firm, planned application. A properly rebuilt system should stop the car squarely without excessive pedal travel. Pulling, grabbing, or a pedal that sinks under steady pressure indicates a fault, not an authentic period characteristic.

Identification and Originality

Serial, Engine, and Body Numbers

A 1936 Dodge should be identified as a D2 from its original serial plate, period registration records, and body details rather than from styling alone. Dodge did not use the standardized 17-character VIN familiar from later cars. Plate location and stamping practice can differ by assembly source and body, so the numbers should be compared with a recognized Dodge serial-number reference before purchase.

The engine carries a separate stamped engine number. It was not intended to match the vehicle serial number character for character, which makes the modern phrase “matching numbers” potentially misleading. A correct-type engine with a plausible production-era number is preferable, but a replacement Dodge or Plymouth flathead may have been fitted during decades of normal service.

Body-number plates, tags, firewall details, and surviving paperwork can help establish whether a coupe, sedan, or open body began life in its present form. Altered rivets, fresh stampings, missing tags, or a title based solely on an engine number deserve careful investigation, particularly where local registration systems once treated the engine as the legal identifier.

Correct Equipment and Finishes

Originality depends on details that are frequently lost during older restorations. The grille, hood side panels, lamps, handles, dashboard instruments, steering wheel, window hardware, bumpers, hubcaps, garnish moldings, and seat frames should correspond to the D2 body style. Parts from adjacent Dodge, Plymouth, and Chrysler models can look convincing from several feet away while differing in dimensions, mounting points, or finish.

Period-correct interiors used cloth in closed cars and weather-resistant trim in open cars, with rubber flooring or carpeting depending on body and equipment specification. Modern velour, incorrect wood-grain patterns, generic gauges, and later sealed-beam headlamps reduce historical accuracy even when neatly installed.

Paint identification requires more than selecting a color from a modern chart labeled “1936 Dodge.” Factory literature, dealer color material, hidden paint beneath moldings, and documented samples should be reconciled because refinishing systems and color names have changed. The D2 predates the later Chrysler fender-tag option coding familiar to post-war collectors, so no unsupported option-code interpretation should be applied.

Common Mechanical Substitutions

Later 218 and 230 cubic-inch Chrysler flathead sixes are common replacements because they fit the same broad engine family and remained available for many years. Twelve-volt conversions, alternators, electric fuel pumps, front-disc-brake kits, modern steering columns, and higher-ratio rear axles also appear regularly. Such changes may improve usability, but their quality and reversibility have a direct effect on collector appeal.

Variant and Body-Style Breakdown

The D2 was a passenger-car family rather than a single body shape. Factory naming can differ among brochures and later references, particularly where “touring” denotes a built-in luggage compartment, but the following forms represent the recognized production range.

No factory D2 homologation special or separate high-output production model is recognized. Open cars command attention because fewer were built and survived, but a complete original sedan can be a better restoration proposition than a convertible assembled around missing or reproduction hardware.

Performance and Dimensional Specifications

Standardized acceleration testing was not routine for ordinary American family cars in 1936, and surviving sources do not provide one universally accepted D2 top-speed or quarter-mile figure. Quoting a modern estimate as a period result would be misleading, so the reference table is restricted to published chassis and engine dimensions.

Shipping weight, overall length, and tire specification differ by body style and equipment. A buyer documenting a particular car should consult the factory specification sheet for that body rather than assigning sedan data to a coupe or convertible.

Compared With Related Dodge Models

1935 Dodge DU

The 1935 DU is the D2's direct predecessor. Both use Dodge flathead-six power and conventional rear-wheel-drive architecture, but the D2 carries revised styling, a more developed steel body, and model-year-specific trim. Grilles, hood panels, instruments, and brightwork should not be assumed interchangeable merely because the cars are adjacent in age.

1937 Dodge D5

The D5 succeeded the D2 for 1937 with another round of body and trim revisions. The later car can resemble a D2 in a poorly captioned photograph, but grille treatment, sheet metal, dashboard details, serial identification, and body fittings separate the two. Restorers should resist buying D5 trim until dimensions and mounting points have been confirmed.

Plymouth P2 and Chevrolet Master De Luxe

The Plymouth P2 was Chrysler Corporation's lower-priced six-cylinder alternative. Its shared corporate engineering philosophy makes some service parts familiar, but visible interchange should never be presumed. Chevrolet's Master De Luxe offered an overhead-valve six and independent front suspension, giving it a different mechanical identity despite competing for many of the same buyers.

Ford Model 68 V8

Ford sold eight-cylinder power as its principal distinction. The Dodge countered with hydraulic brakes and the low-speed tractability of its long-stroke six. In modern ownership, the Ford benefits from enormous hot-rod and reproduction support, while an original D2 rewards a buyer willing to preserve less commonly seen Dodge hardware.

Ownership and Restoration Notes

The flathead six is fundamentally durable, but age-related faults dominate. Cooling passages can accumulate rust and scale, water-distribution components may deteriorate, and an apparently clean radiator may still lack sufficient flow. Persistent overheating should prompt checks of block passages, water pump condition, ignition timing, thermostat operation, and radiator capacity rather than immediate acceptance as normal.

Low oil pressure when hot can reflect worn main and connecting-rod bearings, an aged oil pump, or incorrect clearances from an earlier rebuild. Valve recession, sticking valves, cracked manifolds, carburetor wear, and distributor-bushing play can produce rough running. Before machining, a rebuilder should measure the block carefully and confirm piston, bearing, valve, and gasket availability.

The three-speed gearbox is simple but may suffer from worn bearings, chipped teeth, tired synchronizers, and oil leaks. Clutch chatter can come from contaminated facings, failed engine mounts, linkage wear, or flywheel damage. The torque reaction of the long-stroke engine also makes sound mounts essential.

Rust commonly attacks running-board mounts, lower door skins, rocker and sill areas, floor edges, body mounts, wheel housings, rear body seams, trunk floors, and the lower cowl. Open cars require additional scrutiny around door apertures, top mounts, windshield supports, and structural wood or reinforcement. A body that has sagged can consume far more labor than an engine rebuild.

Routine ownership requires frequent lubrication by modern standards. Kingpins, spring shackles, steering joints, wheel bearings, brake components, and driveline fittings should be serviced according to period instructions, with interval length adjusted for actual use. Long storage is particularly hard on hydraulic brake cylinders, fuel-system components, and six-volt electrical connections.

Buyer and Inspection Points

A D2 should be inspected as a complete mechanical and historical object. The expense lies not only in repairing the chassis, but in finding body-specific pieces that disappeared when these cars had little collector value.

A complete non-running D2 can be a more rational purchase than a running car missing its grille pieces, interior hardware, instruments, and body-specific trim. Mechanical parts often cross within Chrysler's flathead family, while visible D2 components do not.

Collector and Market Relevance

Collector demand follows body style, originality, and restoration quality. Convertible sedans and convertible coupes are considerably scarcer than ordinary closed sedans, while coupes attract both restorers and traditional hot-rod builders. That second market has removed many intact cars from original specification, increasing the significance of surviving coupes with their factory frame, suspension, engine, dashboard, and sheet metal.

Closed sedans remain the practical entry point into D2 ownership. Their values generally do not support indiscriminate professional restoration, so the strongest examples are either well-preserved originals or older restorations completed before trim and labor became prohibitive. A sedan with documented ownership, correct upholstery, intact wood-grain finish, and its original-type drivetrain can be more historically persuasive than a brighter but heavily modified open car.

Auction interest tends to concentrate on convertibles, exceptional coupes, and high-quality original cars. The D2 has no major factory racing derivative to create a separate competition hierarchy. Instead, collectors reward body rarity, correct identification, factory-style presentation, and evidence that the car has not been reconstructed from unrelated Chrysler Corporation components.

Cultural Relevance

The D2 represents the type of durable mid-priced automobile that carried American families, salesmen, and small-business owners during the Depression recovery. Its body shapes also became part of the visual vocabulary of late-1930s streets, from upright sedans to coupes later stripped and modified by post-war hot rodders.

That customization history is double-edged. Dodge coupes and sedans supplied affordable foundations for engine swaps, lowered suspensions, hydraulic-brake upgrades, and custom bodywork, but the same activity reduced the population of stock survivors. Original cars now receive support from the Dodge Brothers Club, Antique Automobile Club of America communities, regional Chrysler clubs, and specialists familiar with pre-war Mopar engineering.

Film and period-drama appearances are usually attributable to body style and era rather than to a famous D2-specific screen role. Claims that a particular car appeared on screen require production records or photographic confirmation, especially because 1935, 1936, and 1937 Dodge bodies are often misidentified in background scenes.

Frequently Asked Questions

What engine is in the 1936 Dodge D2 Six?

The D2 uses a 217.8-cubic-inch L-head inline six, commonly rounded to 218 cubic inches. Its bore is 3.25 inches, its stroke is 4.375 inches, and its factory-rated output is generally listed as 87 horsepower.

What years was the Dodge D2 produced?

The D2 designation applies to the 1936 model-year Dodge passenger-car series. It followed the 1935 DU and was replaced by the 1937 D5.

How can a 1936 Dodge D2 be identified?

Identification should combine the vehicle serial plate, engine stamping, body-number information, registration documents, and D2-specific body details. Because the car predates standardized VINs and some jurisdictions registered vehicles by engine number, no single number should be interpreted without a recognized serial reference.

Does a Dodge D2 have matching engine and chassis numbers?

Not in the later collector-car sense. The engine number and vehicle serial number are separate sequences and should not be identical. Collectors instead look for a correct-type engine with a plausible period number, supported where possible by old records.

What are the main problems with a 1936 Dodge D2?

Frequent concerns include cooling-system scale, worn engine bearings, valve and ignition wear, leaking hydraulic brakes, tired kingpins and spring shackles, gearbox noise, six-volt grounding faults, and rust around body mounts, floors, sills, doors, and the lower cowl.

Are parts available for a 1936 Dodge D2 restoration?

Routine engine, ignition, brake, bearing, and gasket parts benefit from the long service life of Chrysler's flathead-six family. D2-specific grille pieces, trim, instruments, convertible hardware, interior fittings, and unmodified sheet metal are much harder to find.

What makes a 1936 Dodge D2 collectible?

The D2 combines one-year styling, a durable 218-cubic-inch flathead six, hydraulic brakes, and a wide body-style range. Open cars are scarce, while complete stock coupes are desirable because many were converted into hot rods. Across all bodies, correct trim and documented originality carry substantial weight.

Collector Takeaway

The 1936 Dodge D2 deserves attention for a precise reason: it packages proven, serviceable Chrysler engineering inside one-year bodywork that captures Dodge at the point where the upright early-1930s automobile gave way to the fuller steel forms of the late decade. Its long-stroke six, hydraulic drums, beam axle, floor shift, running boards, and built-in touring-sedan luggage compartment record that transition in hardware rather than marketing language.

The best D2 is not necessarily the rarest body or the most polished restoration. It is the car that still explains how Dodge built it, with an honest serial identity, correct visible components, sound steel, and a flathead drivetrain maintained to factory principles. Convertibles supply rarity, coupes carry the hot-rod tension, and sedans preserve the commercial reality of the series. Together they make the D2 one of the clearest surviving documents of Dodge's 1936 engineering and design program.
