Detailed Description

The Motorad CH4992 is an engine coolant water outlet designed for GM vehicles that use a 1.6-inch outlet diameter and a two-bolt mounting pattern. It is built to OE quality standards using proprietary material selection for demanding cooling system conditions, with validation for thermal shock resistance and leak integrity. This makes it a practical replacement for worn, corroded, or leaking coolant outlet housings on applications such as Chevrolet C1500, Chevrolet K2500, and GMC Yukon.

This part cross-references Dorman OE Solutions 902-694 for the same application. The Motorad CH4992 is also listed under common interchange references used in the aftermarket for the same fitment family.

What It Helps Repair

• Coolant leaks at the water outlet or housing
• Corrosion or pitting in the coolant passage
• Cracked or warped thermostat housing connection surfaces
• Improper sealing at the outlet-to-engine interface
• Cooling system service issues caused by a worn outlet assembly

Installation Notes and Tips

Verify the outlet port diameter, mounting hole count, and vehicle application before installation. Clean the mating surfaces thoroughly, inspect the thermostat and adjacent hoses, and replace any damaged seals or corroded fasteners during service. This part is listed for early 1996 Chevrolet G30 and GMC Savana 1500 applications, so confirm the exact engine configuration before ordering.
