Product Details

The Four Seasons 85083 engine coolant water outlet is a direct-fit replacement housing for cooling system service where the original outlet has cracked, corroded, or begun to leak. Its aluminum construction supports reliable coolant routing, while the outlet-only design keeps the part focused on housing replacement rather than thermostat service. This part cross-references Motorad 524KT and CH2836 for the same application.

Fits 2003 Chevrolet SSR, 2004-2006 Chevrolet Avalanche 1500, 2004-2008 Chevrolet Corvette, 2004-2007 Cadillac CTS, and 2005-2006 Chevrolet Silverado 1500, among many other listed GM truck and car applications. It also fits 2006-2009 Chevrolet Impala and 2008-2009 Pontiac G8, making it a practical replacement for a wide range of GM cooling system repairs. The Four Seasons 85083 is also listed for Chevrolet Trailblazer, GMC Envoy, and Buick Allure applications in the covered model years.

Common Problems This Part Can Address

• Coolant seepage at the water outlet housing
• Cracked or warped outlet flange
• Corrosion around the coolant passage
• Failed original outlet on GM cooling system service
• Leak repair during thermostat housing maintenance

Installation Notes

Confirm the inlet diameter, bolt spacing, and outlet style against the removed part before installation. Because the gasket or seal is not included, reuse is not recommended unless the existing seal is in serviceable condition and matches the application requirements. Clean the mating surfaces thoroughly and inspect the thermostat area if the vehicle uses a separate thermostat assembly.

Quality Assurance

Four Seasons lists this water outlet as meeting or exceeding OEM requirements for the specified applications. Verify fitment by year, make, model, and engine configuration before ordering, especially on Chevrolet Silverado, GMC Sierra, and Cadillac CTS cooling system repairs.
