Parts for your 2002 Honda Accord-Radiator

2002 Honda Accord radiator — what it does and how to look after it

A radiator is absolutely relevant and fitted to the 2002 Honda Accord. Honda’s factory service manuals for the 1998–2002 Accord cooling system, plus OEM parts catalogues for both the four‑cylinder and V6 engines, specify a front‑mounted, liquid‑cooled aluminium radiator with electric fans. Those technical sources outline the coolant flow, thermostat operation, fan control, and the radiator’s role in keeping engine temperatures in the sweet spot.

On this Accord, the radiator sheds heat from the engine coolant as air passes through its fins under the bonnet. The thermostat, water pump and fans team up to hold a steady operating temperature for reliable performance, good fuel economy and long engine life. On many automatic models, the radiator also houses a small heat exchanger for automatic transmission fluid, so maintaining it protects more than just the engine.

As part of routine servicing, it’s smart to inspect the radiator core, end tanks and seams for weeping, check the cap seal, and look over the upper and lower hoses for softness, cracks or swelling. If the car’s running hotter than usual, the heater’s gone cold, or there’s a sweet coolant smell, the radiator and related plumbing deserve a proper look.

• Use Honda Type 2 coolant (or an equivalent silicate‑free OAT) mixed 50/50 with demineralised water if not premixed.
• Flush and refill at sensible intervals (typically every 5 years or around 100,000 km, or sooner if the coolant is discoloured).
• Bleed air after refilling
