So I had a pretty bad coolant leak due to a cracked thermostat housing. I replaced the thermostat housing and thermostat only to find that there was still a slight leak. I replaced the thermostat sensor as the o-ring on it was in rough shape and the sensor itself looked like it had seen better days. I flushed the entire system of coolant and refilled it. When I turned the car back on, the air coming out of the vents started to warm up along with the engine, seemed great. I fixed the car in my father's garage, on my way home the car started blowing cold air even though the gauge was showing that the engine was warm. Could this just be the result of a faulty thermostat in the part that I ordered? Or an issue with the fact that I flushed and refilled the car?

You probably have an air pocket trapped in the system from the flush and refill. How did you do the refill process?

Hey Jim,

I drained the fluid from the spigot in the bottom of the radiator, put the plug back in and then filled it up. At one point after refilling the car, however, I did take the thermostat housing off again as I thought that it may have been improperly seated (turned out the leak was from around the sensor not the bottom of the housing). I reinstalled the housing and then topped my car up.

How would I get rid of a bubble if there was one?

Oh nevermind, I found a good youtube video. Thanks for the help, I'll let you know if it worked!

That did the trick, thanks!

You're welcome. Glad to hear it was something simple
