Gates 31532 cooling system components for the 1999-2010 Chevrolet Silverado 1500 4.3L / 4.8L / 5.3L and other vehicles is a threaded coolant bottle cap, listed as an OE-type radiator cap, that holds pressure in a closed coolant recovery system.
- Corrosion-resistant construction in heavy-gauge metal or high-quality plastic, depending on the application
- Meets or exceeds environmental regulatory standards to reduce air pollution
- Built to OE-level tolerances in function, form and fit
- Application-specific vent and vacuum-relief valves for precise pressure control
A cap that no longer holds pressure can show up as coolant seepage around the cap, an overflowing coolant bottle or an engine that runs hot. These signs alone do not prove the cap is at fault, since a leaking hose can look the same, so find the cause before you replace it.
This cap also fits the 1999-2010 GMC Sierra 1500 4.3L / 4.8L / 5.3L, the 1999-2010 Chevrolet Silverado 2500 5.3L and many other vehicles. If your truck or car isn't named here, open the Buyer's Guide tab and look up your exact model and engine.
