Verify that your existing cooler is a FOUR PASS design before ordering — the N14 and 855 families also use a three pass cooler, and the two are not interchangeable. Confirm by engine serial number if you are unsure. Replace the O-rings and sealing rings supplied in the kit rather than reusing the originals, and pressure test the cooling system after installation.
