What It Helps Fix

• Cooling system service needs on GM truck and van engines
• Thermostat housing replacement when the thermostat is reused separately

Installation Notes and Tips

Confirm the inlet diameter, bolt-hole spacing, and overall height against the original part before installation. This outlet is listed without a thermostat, so transfer or replace the thermostat separately if your application requires one. Clean the mating surfaces thoroughly and inspect the gasket area for debris, old seal material, or corrosion before assembly.
