So my cel has been on and the code is for the thermostat. My car was running really cold, specially when i'm on the highway. Sometimes it stayed at 0. So finally got a Stant thermostat and decided to change it today.
when i took the old one out IT WAS BROKEN IN HALF. The spring valve was missing. Not sure if it was cut out. Can this brake of like this? This is the first time i see this.
