Engine Oil Cooler Fitting

Caution: Refer to Fastener Caution in the Preface section.

Procedure

Remove the plastic caps from the quick connect fittings by pulling the caps back along the pipe before installation.

Tip

    • Do not remove the upper and lower engine oil cooler fittings from the radiator at the same time, otherwise the engine oil cooler may fall inside the radiator end tank.
    • The correct thread engagement is critical. Cross-threaded fittings can achieve proper tightness and still leak.
