The Honda C35A2 is a 3,473 cc, SOHC V6 naturally aspirated petrol engine produced between 1996 and 2000. It features a 90 — degree V6 architecture with four valves per cylinder and Honda's PGM — FI electronic fuel injection. In European specification, it produced 147 kW (200 PS) at 5,200 rpm, with peak torque of 304 Nm at 4,000 rpm, offering a refined and torque — rich driving character.
Fitted primarily to the second — generation Honda Legend (KA9), the C35A2 was engineered for…
Production years 1996–2000 meet Euro 2 standards .
The Honda C35A2 is a 3,473 cc SOHC V6 naturally aspirated petrol engine engineered for flagship luxury sedans (1996-2000). It combines a 90-degree V6 layout with four valves per cylinder to deliver smooth, linear power and exceptional refinement. Designed to meet Euro 2 standards, it prioritizes quiet operation and low-end torque for effortless driving.

The Honda C35A2 was used exclusively in Honda's KA platform with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts and a unique exhaust manifold for the Legend. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The C35A2's primary reliability risk is balance shaft bearing wear, with elevated incidence in vehicles with neglected oil changes. Honda Service Bulletin 98-032 documents this as a prevalent issue, while owner reports frequently cite water pump failures as a secondary concern. Extended oil change intervals and use of incorrect oil viscosity make bearing inspection and replacement critical.
Analysis derived from Honda technical bulletins (1996-2000) and owner-reported failure data (1996-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The C35A2 is generally a very robust and smooth engine when properly maintained. Its main vulnerabilities are the balance shaft bearings and the timing belt/water pump. With regular oil changes using the correct 5W-30 oil and timely replacement of the timing belt and water pump, these engines can easily surpass 250,000 km. Its non-VTEC design is simpler and potentially more durable than high-revving variants.
The most frequent issues are worn balance shaft bearings causing vibration, water pump failures leading to coolant leaks, and timing belt tensioner wear. Valve cover gasket leaks are also common with age. These are well-documented in Honda service bulletins and enthusiast communities.
The C35A2 was used exclusively in the second-generation European-market Honda Legend (KA9 chassis, 1996-2000). It was the standard engine for this flagship sedan, offering a balance of power, refinement, and reliability.
While not a common tuning candidate, the C35A2 can be modified. Basic bolt-ons like a performance exhaust and intake can yield modest gains. More significant power increases would require forced induction (supercharging or turbocharging), which is complex due to the engine's size and layout. The bottom end is strong, but the SOHC head limits high-RPM potential.
Fuel economy is moderate for a large luxury sedan. Expect around 11.0–13.0 L/100km (26–22 mpg UK) in mixed driving for a Legend. Highway cruising can return ~8.5 L/100km (33 mpg UK), while city driving will be closer to 15 L/100km (19 mpg UK). Economy is heavily influenced by the vehicle's weight and aerodynamics.
Yes. The C35A2 is an interference design. If the timing belt snaps, the pistons will collide with the valves, causing severe internal engine damage. This makes adhering to the 100,000 km timing belt replacement interval absolutely critical for preventing catastrophic failure.
Honda specifies a 5W-30 viscosity oil meeting API SJ/SL (or higher) standards. Using a high-quality synthetic or semi-synthetic 5W-30 is recommended. Oil should be changed every 10,000 km or 6 months to protect the balance shaft bearings and ensure overall engine longevity.
