This American made, modified premium thermostat has a larger heat motor/spring assembly for more precise temperature control along with a heavy gauge chrome plated steel housing. This is a direct-fit replacement for your original or aftermarket-stock thermostat.

Features and Benefits:
- Improved Cooling
- 170 Opening Temperature
- Direct Fit Replacement
- Simple Installation

Whether you are using an aftermarket radiator or not, this performance thermostat will provide the best possible heat dissipation from your setup along with a faster warm up time and better cold weather performance than a 160 degree unit or a thermostat with holes drilled in the diaphragm.

Reische believes the 170 degree opening temperature is the ideal balance for high performance engines, providing high flow to your radiator by mid-180 temperatures while still providing good all season performance. With proper fan settings your coolant temperatures in cool weather will be in the 170s and in hot weather the 180s, giving those running high levels of timing and/or boost added protection against engine-damaging detonation as well as maximum power output.

Please Note: A gasket is not included due to the multitude of applications.

Tech Tip: Thermostats tend to have faulty operation or stick after years of service. Replace the thermostat during regular tune-ups to keep everything working properly. Adding new coolant with the thermostat will help keep your engine running at its proper operating temperature.
