Hold your engine at its intended operating temperature with the Gates Engine Coolant Thermostat 33877. It installs as a direct-fit replacement across a broad range of applications, including the 1997-1999 Acura CL, 1995-1999 Honda Accord, 1991-1999 Mitsubishi 3000GT and 1993-1999 Toyota Land Cruiser — see the Buyer's Guide tab for the full list of 23 vehicles.
- Temperature-regulated coolant flow: opens and closes in response to coolant temperature, controlling flow between the engine and radiator so the engine can reach and hold its normal operating temperature.
- Direct-fit replacement: designed to install in place of the original thermostat on the listed applications.
- Warm-up management: stays closed during warm-up to help the engine reach temperature quickly, then modulates flow to keep it stable.
The thermostat is a temperature-sensitive valve in the cooling circuit. If a stuck-closed thermostat is the cause of overheating, or a stuck-open one is keeping the engine running cold with weak heater output or fluctuating temperature readings, replacing it with this unit restores proper coolant regulation. Diagnose the cooling system before replacing, as these symptoms can have other causes.
