Nissan Engine Oil Cooler Assembly

This OEM-grade oil heat exchanger keeps your engine safe when the work gets hard. It stabilizes lubricant temperature, so viscosity stays in range, bearings are protected, and the turbo stays clean. Essential for towing, off‑road, steep climbs, hot climates, and city traffic, it helps maintain oil pressure and extends service life of the engine and the oil itself. Built with brazed aluminum plates and quality seals for factory fit and durability.

How it works

Hot oil routes through stacked plates while engine coolant absorbs the heat. This coolant‑to‑oil design speeds warm‑up after a cold start and caps peak temperatures under load. The result is steady film strength, quieter valvetrain, and reliable pressure at idle and high RPM.

When it fails ⚠️

Signs include rising oil temp, low hot‑idle pressure, ticking lifters, burnt‑oil smell, or limp mode. A cracked core can leak or mix fluids: milky coolant, coffee‑colored oil, white exhaust, and overheating. Driving on risks turbo coking and bearing damage. Replace promptly; renew gaskets, torque to spec, refill oil and coolant, and bleed air.
