How does a water-cooled oil cooler work?
A water-cooled oil cooler uses the vehicle's engine coolant to dissipate heat from the engine oil. Coolant flows through passages in the cooler, absorbing heat from the oil that passes through a separate set of passages, thus maintaining optimal oil temperature.
Troubleshooting
Oil leaks detected after installation
Ensure all seals and gaskets were replaced with new ones and are properly seated. Verify that all mounting bolts are torqued to the manufacturer's specifications. Check coolant and oil lines for secure connections.
Engine oil temperature is too high
Verify that the vehicle's coolant system is functioning correctly and has adequate coolant levels. Check for any blockages in the oil cooler core or the associated oil/coolant lines. Ensure the oil cooler is the correct part number for the vehicle.
Coolant is contaminated with oil
This may indicate an internal failure of the oil cooler. The unit should be replaced immediately. Flush the cooling system thoroughly after replacing the oil cooler.
Reduced engine performance or warning lights
Consult a mechanic to diagnose the cause. Issues with oil temperature regulation can lead to performance derating or warning lights. Ensure the part is correctly installed and compatible.

Setup, Compatibility & Care
Compatibility Check: Before installation, verify that your vehicle's Make, Model, Year, Engine Code (e.g., CJCD, CAAA), and Transmission Type (6-speed manual) match the specifications for Nissens Oil Cooler - 91158. Cross-reference with OEM part numbers 03L115389B, 03L115389C, 03L115389G, 03L115389H, 03L117021B, or 03L117021C.
Installation: This oil cooler is a critical component and should be installed by a qualified mechanic. Ensure the engine is cool before starting. Proper torque specifications must be followed for all mounting bolts and connections. The included gaskets and seals must be used to prevent leaks. The cooler integrates with the vehicle's coolant system; ensure coolant levels are correctly maintained post-installation.
Care: Regularly inspect the oil cooler and associated hoses for any signs of leaks, corrosion, or damage. Maintain the vehicle's coolant system according to the manufacturer's recommendations, as a properly functioning cooling system is vital for the oil cooler's performance. Avoid using harsh cleaning chemicals directly on the unit; a damp cloth is sufficient for exterior cleaning.
