The oil cooler is a smaller radiator separate from the engine's main radiator that keeps the oil supply at a consistent optimum temperature. Its purpose is to cool the oil flowing through the coils, thus extending the life of the engine and transmission.

Signs of a damaged oil cooler:
1. Oil spill
2. Coolant leakage
3. Coolant mixed with oil

Although the oil cooler is designed for a long service life, it still requires attention when the above abnormal conditions occur. Other signs of a malfunctioning oil cooler include decreased engine power, engine misfires, elevated engine temperatures and increased black exhaust emissions. Any of these symptoms mean your machine needs to be checked out and serviced ASAP.
