The engine oil cooler maintains optimal oil temperature by exchanging heat with coolant or air. Overheated oil loses viscosity and lubricating ability, while an oil cooler leak can contaminate the coolant system. At CarParts247 we stock oil coolers from Behr, Nissens, and NRF.
Oil cooler failure typically manifests as internal leakage (oil mixing with coolant) or external leakage. The consequences of delayed repair can be severe.
When an oil cooler fails internally, both the oil and coolant circuits are contaminated. Both systems must be thoroughly flushed before and after fitting the replacement.
