Do not use petroleum products on the coolant plumbing o-rings. The o-rings will swell and cause the connection to leak.
Install two new o-rings on the oil cooler water inlet and outlet transfer tubes.
Lubricate the o-rings with clean engine coolant, soapy water, or vegetable oil to avoid pinching the o-rings while assembling.
While holding the mounting flange in place, install both transfer tubes into the oil cooler as far as possible. The straight sides of the transfer tube flanges must face each other when installed.
If equipped with four oil cooler thermostat mounting flange capscrews, install the four oil cooler thermostat mounting flange capscrews. Tighten the capscrews alternately and evenly.
