OEM Thermostat to Thermostats

I installed this thermostat on my 2004 Mustang GT. I tested it with an OBD-II reader for accurate readings and the thermostat opened right up at 192 degrees, which is the default setting for this engine. With my engine, it rises to about 212 degrees over a longer period of time when idling. After that it stopped moving and cooled down to about 200 during the ride. I had no problems with overheating or long warm-ups.

Pros
  • Country of Origin: China
Cons
  • Expensive
