Keep coolant flowing at the right temperature with the Gates Engine Coolant Thermostat 33939, an integrated-housing thermostat that opens and closes to regulate coolant flow and help the engine reach and hold its normal operating temperature. It's a direct-fit replacement for the 2002-2009 Chevrolet TrailBlazer, 2002-2006 Chevrolet TrailBlazer EXT, 2002-2009 GMC Envoy, 2002-2006 GMC Envoy XL, 2002-2004 Oldsmobile Bravada, 2003-2008 Isuzu Ascender, 2004-2007 Buick Rainier, 2004-2005 GMC Envoy XUV, and 2005-2009 Saab 9-7X — see the Buyer's Guide tab for engine-level fitment.
- Integrated housing design: Gates integrated thermostat housings are engineered for accurate temperature regulation and control to help engines run efficiently, offering an aftermarket alternative to OE dealership units.
- All-in-one, bolt-on assembly: includes everything needed for a complete job — thermostat, insert, seal and housing.
- Meets or exceeds OE standards for fit, form and performance.
- Precision temperature regulation and control, including application-specific adaptive MAP-control.
Signs the original thermostat may need replacing include overheating, an engine that runs cool or takes too long to warm up, erratic temperature-gauge readings, or coolant leaking at the housing. If a stuck or failed thermostat is the cause, this assembly replaces it.
