Installation Notes and Tips

Confirm the vehicle’s original outlet style before installation, especially on Chevrolet P10, P20, and P30 applications and GMC van models with configuration-specific notes. Verify the inlet diameter, bolt-hole spacing, and overall height against the removed part before assembly. Clean the mating surfaces thoroughly and install with the included gasket or seal to help achieve a proper seal.

Because this outlet is supplied without a thermostat, reuse or replace the thermostat separately only if your application requires one elsewhere in the cooling system. Always refill and bleed the cooling system according to the vehicle service procedure after installation.
