Installation Notes and Tips

Verify inlet diameter, bolt spacing, and mounting flange dimensions before installation. Clean the mating surface thoroughly, inspect adjacent hoses and clamps, and transfer any required sensors or fittings from the original setup if applicable. Because this is a water outlet without a thermostat, confirm that your vehicle uses a separate thermostat arrangement before ordering.
