Comments about Beck/Arnley Thermostat:

Purchased the Beck Arnley product based on assumption that it would be higher quality as it was approximately double the cost of the Stant thermostat. I was disappointed when I opened the box and found nothing special for double the price. Did not look like the quality of the unit I took out of my Lexus and replaced. Only replaced the old one based on age.

      Any liquid-cooled car engine has a small device called the thermostat that sits between the engine and the radiator. The thermostat in most cars is about 2 inches (5 cm) in diameter.
