Installation Notes and Tips

Verify engine application, thermostat temperature rating, and bolt-hole alignment before installation. This housing uses a 2-bolt pattern and does not list bolts or a gasket/seal as included in the attributes, so confirm all required sealing components are on hand before service. Clean the mating surfaces thoroughly and inspect the cooling system for contamination or damage before reassembly.
