Extreme cold caused thermostat problem
Last week -30F degree temp caused no heat inside the car. Later I took it to the mechanic and he said thermostat is out. and it is $500 job.
I changed that sucker some years back, it is under the intake manifold and difficult to take out. I am thinking to change or flush the antifreeze, anyone had any luck with that? |

Re: Extreme cold caused thermostat problem
If the thermostat is stuck open, flushing etc won't do any good.

Re: Extreme cold caused thermostat problem
As aleekat said if it is a thermostat problem the only fix is to replace the thermostat. With the thermostat being stuck open the coolant can never reach operating temperature. Fresh coolant won't fix that.

Re: Extreme cold caused thermostat problem
If the 'stat didn't close at -30, it's probably never going to close. A flush to clear it out would be nearly miraculous.
BTW - It was a few degrees cooler here, and my two daily drivers stayed very low on their temperature gauges, but still well above 160°F.
