Granatelli 98-17 GM LS 160 Deg Thermostat

This is the Granatelli 160-degree thermostat, designed for GM LS engines from 1998 through 2017. If you're looking to manage engine temperatures more precisely, especially in performance applications or hot climates, a lower-temperature thermostat like this can make a difference. It opens sooner than a stock thermostat, allowing coolant to circulate through the radiator at a lower overall engine temperature.

Granatelli built this thermostat to fit a wide range of GM vehicles equipped with the popular LS engine series. This includes models like the Chevrolet Camaro, Corvette, SS, and many Silverado and Sierra trucks and SUVs. By opening at 160 degrees Fahrenheit, it helps prevent your engine from running too hot, which can be beneficial for performance and longevity, particularly if you've made other modifications to your engine.

When installing this, remember it's a direct replacement for your factory thermostat. Just make sure to use a fresh coolant fill and properly bleed the air out of the system afterward for optimal performance.
