Installation Notes and Tips

Verify engine and model-year fitment before installation. This housing uses three mounting holes and a 90-degree neck angle, so confirm hose routing and connector alignment before tightening. The thermostat is not included, and bolts are not included, so reuse or source the correct related components as needed for the repair. For best results, inspect the mating surfaces and cooling hoses before reassembly.
