How to Install Engine Oil Coolers

To start with, check the sharp edges in the work area and make sure that you do not expose the oil hose to the hot surface. Also, keep the length of hoses longer than the taken measurements and always use pipe thread in all the fittings. However, it is suggested not to over-tight the fittings.

1. Decide the Mounting Location

For the best location of the cooler in the system, it is advised to install it, where it will receive the most of the cool air from the vehicle fan and motor.

2. Inspection of Filter

First, insert the sandwich adapter’s depth into the oil filter in order to confirm its clearance. In case, there is not enough of the clearance in the filter then, its remote mounting is done or short filter is used. Here, the short filter’s thread must adjust the adapter.

3. Mount the Engine Oil Cooler

Step1: Install the pipe thread fitting into the sandwich adapter and the cooler. Next, just place the engine oil cooler (do not fit yet) where you want to install it.

Step2: Coat the oil of the engine onto the O-ring seal of the sandwich adapter.

Step3: Then, with the right-colored ring, insert the adapter and tighten it in the cylinder block over the adapter.

Step4: Next, for the routed hose, make sure to position all the fittings on the sandwich adapter and toughen the nuts on it.

Step5: Followed by this, cut the hoses more than the rough length and insert it in the cooler with 90o turns or with greater radius. By this, it would allow for the easy flow of the oil through the cooler.

4. Test the Installation of Engine Oil Cooler

To test the oil cooler, start the engine and look for the oil pressure and cooling radiator in the system. If both ends of the cooler are warm after a certain time, this confirms the proper installation of it. Or else troubleshoot the problem and re-concern the instruction guide.
