Gates 86-01 Acura Integra / 90-02 Honda Accord / 84-09 Civic / 87-91 Sterling Super Stat Thermostat

This is the Gates 33340S Super Stat Thermostat, a direct replacement for many Acura, Honda, and Isuzu vehicles. It's designed to regulate your engine's operating temperature by controlling the flow of coolant to the radiator. When your engine reaches its optimal temperature, this thermostat opens up, allowing coolant to circulate and prevent overheating. If it's stuck closed, your engine will quickly overheat, and if it's stuck open, your engine may struggle to reach its proper operating temperature, especially in colder weather.

Gates thermostats are well-built and made to meet or exceed original equipment specifications. This particular model is a popular choice for a wide range of applications, including popular models like the Honda Civic, Honda Accord, and Acura Integra. It's a straightforward part to replace, making it a common maintenance item to address when you're doing other cooling system work, like replacing hoses or the water pump.

When installing a new thermostat, it's a good idea to replace the gasket as well, and ensure the sealing surface on the engine is clean. This helps prevent leaks and ensures the thermostat functions correctly.
