Mishimoto Racing Thermostat; 169-Degree (07-15 V8 Sierra 1500)Find parts that fit my vehicle

Low Activation Temperature. Unlike stock thermostats, the Sierra 1500 Performance Racing Thermostat opens at 169-degrees, making it ideal for hot climates and high horsepower applications. OEM thermostats do work under normal operating conditions. But when additional power and torque are added, temperatures and pressure go up accordingly. An aftermarket Misihomoto racing will make a noticeable difference in engine temperature and lifespan.

Quality Construction. A thermostat is only as good as what it’s made of. The Sierra 1500 Performance Racing Thermostat is built from high-quality materials such as rust-free stainless steel and high-end copper. The gasket is made from oil-resistant rubber and will provide years of leak-free service.

Trouble-Free Installation. The Sierra 1500 Performance Racing Thermostat is simple and easy to install. Simply remove the old thermostat and drop the new one in place. Make sure the engine is cool and all coolant is drained before attempting it. Pro tip: Take extra caution when removing the old thermostat to not damage the mounting surface. Any scratches or marks on the engine will cause issues such as leaks down the road.

Accurate Reading. Mishimoto Sierra 1500 Performance Racing Thermostats are engineered to accurately open and close repeatedly. They are built to the highest industry standards are ensure a precise and accurate reading each even every time. There is a reason why Mishimoto is the industry leader in automotive cooling products.

Application. To ensure quality fitment, the Sierra 1500 Performance Racing Thermostat is made to fit several LS and Vortec-based engines from GM including the 2007-2015 Sierra 1500.

Mishimoto has developed a racing thermostat engineered specifically for the Chevrolet/GMC V8. The Mishimoto thermostat fits flawlessly into your stock thermostat housing. It will promote greater cooling efficiency throughout your engine. Mishimoto racing thermostats will significantly lower high engine temperature produced by modified and upgraded engines. Once the engine is fully warmed up the Mishimoto Racing thermostat will open up at a lower temperature than the stock thermostat, allowing the coolant to flow through the engine sooner thus reducing and maintaining cooler engine temperatures. And improving long term reliability of your vehicle's cooling components.
