Features and Solutions
Focusing on what's important.
Crack Temperature, Aka. Opening Temperature
The "crack temperature" refers to the moment when the thermostat begins to open, akin to a door "cracking" open. This is also the temperature rating that is stamped in the thermostat and is how the automotive industry classifies the opening temperature.



See the crack temperature in the product specs at the bottom of the page.

Fully Open Temperature
marks the point at which the thermostat is fully open, allowing maximum coolant flow. See the fully open temperature in the product specs at the bottom of the page.
