Gates 33625 cooling system components for the 2011 Chevrolet Silverado 1500 4.3L and other vehicles come as an adhesive-backed thermostat gasket that seals the thermostat where it meets its housing.
- Adhesive backing makes it easier to line the gasket up with the thermostat housing.
- Intended to give a leak-free fit at the thermostat.
- Self-adhesive backing holds the thermostat in place while the water outlet is installed.
- Increases installation efficiency.
A worn gasket at the thermostat housing can show up as coolant seepage around the housing, a falling coolant level or overheating. These signs alone do not prove the gasket is at fault, since a weeping hose connection nearby can leave coolant in the same spot.
The 1988-1996 Chevrolet C1500 and the 1988-1996 Chevrolet K1500, each with the V8-6.2L or V8-6.5L, are also on its fitment list, along with many other vehicles. For any other vehicle, find your make, model and engine in the "Vehicles it fits" section.
