Gates Heavy-Duty Engine Coolant Thermostat with Seal

The Gates Heavy-Duty Engine Coolant Thermostat with Seal helps regulate engine operating temperature in demanding applications. It opens and closes at a calibrated temperature to control coolant flow between the engine and the radiator. This helps the engine warm up efficiently and then hold a steady operating temperature. Use it as a replacement for a worn, sticking, or failed thermostat.

Key Features:

• Heavy-duty construction intended for engines that run under high load and sustained operating temperatures
• Supplied with a seal to help prevent coolant leaks at the thermostat housing
• Calibrated opening temperature for consistent coolant flow control and engine temperature regulation
• Helps maintain proper operating temperature, which supports fuel efficiency, performance, and emissions control
• Backed by Gates, a respected name in engine cooling, belts, hoses, and fluid-transfer components

A thermostat that is working properly helps protect the engine from overheating and from running too cool, which can cause excess wear. Replacing the seal along with the thermostat helps ensure a secure, leak-free fit. Many installers also flush or refill the cooling system with fresh coolant at the same time.
