After Driving for 7 hours, the car starts pumping COLD air into the cabin with the heat on.
I was driving from NY to MD, about 7 hours total, and at the beginning of my
trip the car heat was working. It normally gets too hot, so i turn it off
occasionally. Toward the end of my drive, I turned the heat on and it was
blowing COLD air at me. I tried letting it run for a while and changing the
settings but all of the air was cold, after a long drive. The engine was clearly
warmed up. Help!
Coolant level might be low. Is there coolant in the reservoir by looking at it? Don't remove the cap till the engine has cooled down.
Thank you for replying! I did go and check the coolant- its totally empty. I called my mechanic and he suggested I probably have a leak. Any idea what these things take to repair?
Check the radiator hoses and the radiator for leaks, maybe they need replacing but if the leak is really small I would try Alumaseal and see it that stops the leak.
Be sure and replace the coolant with 50/50 water and anti-freeze or even a higher ratio of anti-freeze since you live in a cold winter area. The bottle will tell you the proper ratio for your low temperatures.
