| The heart of the Stant brand thermostat is the ELAC® heat motor. The unique properties of the heat motor result in a consistent and precise response to the cooling system's needs. This is achieved through the use of a precisely formulated, thermally expansive wax fill that is calibrated to operate within OEM requirements.
The Stant heat motor is powered by a precisely formulated thermal responsive wax pellet in a heat conducting copper cup equipped with a stainless steel piston inside an elastomeric boot. The exact length of the stainless steel piston assures the prompt and precise operation of the thermostat valve.
Each manufacturing process is rigidly controlled with world-class quality controls. Then a 100% calibration is conducted for each heat motor to guarantee quality and performance.
Finally, the heat motor is placed in a stainless steel assembly consisting of a valve, flange, bridge and spring. The completed assembly provides a securely sealed, heat responsive valve that keeps engine temperatures within original equipment specifications.

 What Temperature Thermostat Do I Need? Thermostats have a “rated” temperature (such as 180F or 195F). This is the temperature the thermostat will start to open, releasing heated coolant from the engine into the radiator. The thermostat will fully open once the coolant gets another ten or fifteen degrees warmer.
| OE TEMPERATURE |
These thermostats match the OEM-specified temperature rating for the vehicle. Manufacturers recommend an OE temperature thermostat for most engines, especially for:
- Modern engines with computers that use the coolant temperature to help control the fuel, emissions and other important systems
|
| ALTERNATE TEMPERATURE |
These thermostats have a temperature rating below (cooler than) the OEM-specified temperature rating for the vehicle. This option may make sense for use in:
- Modified Engines
- Performance Applications
- Older / Classic Vehicles
|
 Cooling System Maintenance | Tips & Tools Without regular maintenance, cooling system components will degrade and fail prematurely, which can lead to costly engine damage. Protect your engine with simple preventative maintenance:
- Completely drain and flush the system using Cooling System Flush prior to installation. Flushing the system is critical to prevent system contamination and failure.
- Consider replacing the Radiator Hoses (and Hose Clamps) and Radiator Cap as part of routine preventative maintenance. System contamination can cause these parts to degrade and fail over time, which can lead to severe engine damage from overheating.
- Refill radiator with fresh Coolant / Antifreeze according to the volume and formula specified in your Owner's Manual. Inspect levels and condition every year.
