The Cadillac V2 is a 4,521 cc, V8, naturally aspirated petrol engine produced between 1936 and 1949. It features a pushrod OHV 16 — valve configuration with carburetted fuel delivery and mechanical ignition, delivering 97 kW (132 PS) in its primary application. Designed as a smooth, high — torque powerplant, it emphasizes low — RPM drivability and quiet operation for luxury grand touring.

Production years 1936–1940 meet pre-regulation standards; 1941–1949 models incorporate improved crankcase ventilation per GM internal standards (GM Engineering Bulletin #E-41-08).
The Cadillac V2 is a 4,521 cc V8 naturally aspirated engine engineered for full-size luxury applications (1936–1949). It combines pushrod OHV architecture with single-barrel carburettion to deliver smooth, linear power and strong low-end torque. Designed for refinement, it prioritizes ride comfort and reliability over high-RPM performance.

The Cadillac V2 was used across Cadillac's Series 60, Series 62, and Series 75 platforms with longitudinal mounting. This engine received platform-specific adaptations-revised engine mounts in the Series 75 and modified transmission linkages in the Series 62-and from 1941 the updated Series 60 models adopted revised intake manifolds with improved carburettor calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The V2's primary reliability risk is intake manifold gasket failure on high-mileage engines, with elevated incidence in vehicles used for short trips. Internal GM engineering reports noted increased intake vacuum leaks beyond 50,000 km, while field data from vintage car clubs shows a notable share of idle instability from degraded gaskets. Extended short-trip operation and delayed maintenance increase thermal cycling stress, making coolant and oil quality adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The V2 is a robust, low-stress engine when maintained properly. Regular oil changes (every 3,000 km) with SAE 30 mineral oil are essential. Engines with documented service history and no overheating incidents can exceed 100,000 km reliably. Its pushrod design and conservative tuning contribute to long-term durability in daily driving applications.
The most common issues include intake manifold gasket failure, carburettor clogging, ignition points wear, and oil leaks. These are documented in GM service literature and prevalent in high-mileage or poorly maintained examples. Preventative maintenance significantly reduces failure risk.
The V2 was used in the Cadillac Series 60 (1936-1949), Series 62 (1938-1949), and Series 75 (1937-1949). It was not used in base trims or front-wheel-drive configurations. The engine was exclusive to North American markets and large-format luxury sedans.
Limited tuning headroom exists due to its naturally aspirated, low-RPM design. Performance gains come from dual-carburettor conversions, camshaft upgrades, and exhaust optimization. However, the engine is optimized for smoothness and torque. Most tuning focuses on reliability and idle quality rather than large power increases.
Fuel consumption is moderate for a large-displacement V8. In the Series 60, combined consumption is approximately 16.0 L/100km (~18 mpg US). City driving may exceed 20 L/100km (~12 mpg), while highway cruising can achieve ~13.0 L/100km (~18 mpg). Driving style significantly impacts real-world economy.
No. The V2 is a non-interference engine. If the timing chain fails or skips, the pistons will not contact the valves, preventing catastrophic internal damage. The front-mounted single-row chain is robust, but inspection after 50,000 km is advised in high-mileage applications.
GM specifies SAE 30 mineral oil. This viscosity is essential for lifter quietness and camshaft protection. Oil must be changed every 3,000 km or quarterly, and OEM-approved filters should be used to ensure proper flow and filtration.
