To have the oil cooler removed, one has to first disconnect the clamp on the negative terminal of the battery, then drain the coolant. After that loosen the lug nuts, then raise the vehicle and support it on jackstands after that remove the engine oil and oil filter. Remove the upper and lower coolant hoses from the inlet and outlet ports, undo and remove the oil cooler nut and outlet and extract the oil cooler. To install place the flat side of the oil cooler to the oil filter adapter and apply clean engine oil and tighten the fitting to the recommended torque. Change an oil filter and replace the lost oil and then replace the lost coolant in the car's engine. Last, take to full operational temperature, while doing so check and ensure no leakages are present.
