Using these K - Tuned oil cooler fittings is easy. First, make sure your car is a K - Series block with an oil cooler (it won't fit K24Z Series). Install one fitting on the water pump and the other on the block. For the best results, pair them with K - Tuned silicone hoses. If you have an OEM timing cover, you might need to do a little trimming on the pry tab of the rear fitting, but Drag Cartel and Skunk2 covers are ready - to - use. Remember, the kit doesn't come with oil cooler hoses, tensioner cover, or pulley kit, so you'll need to get those separately if you need them. To keep these fittings in good shape, regularly check for any signs of wear or leaks. Clean them gently with a soft cloth and mild cleaner if they get dirty.
