Product Details

Motorad Standard 332-180 is an engine coolant thermostat engineered for vehicles that require a 180F operating range. The thermostat opens at 180 degrees Fahrenheit to regulate coolant flow through the cooling system, helping the engine reach and maintain the intended temperature. Its copper case and wax element are selected for responsive operation under demanding cooling-system conditions. The offset layout, air relief valve, and OEM-style sealing features support proper fitment in applications that call for this configuration.

Fitment coverage includes 2006 Mitsubishi Lancer; 1996 Chevrolet C1500, C1500 Suburban, C2500, C2500 Suburban, C3500, Express 2500, Express 3500, G30, K1500, K1500 Suburban, K2500, K2500 Suburban, K3500, P30, and Tahoe; 1996 GMC C1500, C1500 Suburban, C2500, C2500 Suburban, C3500, G3500, K1500, K1500 Suburban, K2500, K2500 Suburban, K3500, P3500, Savana 2500, Savana 3500, and Yukon; plus 1988-1995 Chevrolet and GMC truck, van, and SUV applications listed in the fitment data.

Common Issues This Part Can Address

• Engine running too cool or taking too long to reach operating temperature
• Temperature fluctuations caused by a worn thermostat
• Restricted coolant flow from a thermostat that no longer opens correctly
• Cooling-system service on 180F OE-spec applications
• Replacement for a thermostat with air-bleed or offset-design requirements

Installation Notes and Tips

Verify the housing style, bypass dimensions, and temperature rating before installation. This thermostat does not include a gasket or seal, and no installation tool is included. Clean the thermostat housing and mating surfaces thoroughly, then confirm the jiggle pin weep hole is oriented as required by the vehicle application. Refill and bleed the cooling system according to factory service procedures to reduce trapped air.
