1999 Mercury Sable Repair Question
1999 Mercury Sable Repacing Thermostat
1999 Mercury Sable 6 cyl Front Wheel Drive Automatic 140000 miles
As the weather has gotten colder, I turned on care heater. The heater takes a long time to get going. I think the thermostat is frozen in the open position.
I need instructions (as well as a diagram if at all possible) on how to change the thermostate. I have not done this type of work on the car for quite a while, but would be very happy to try rather than pay ~$100 that I can not afford right now.
Thanks for your help.
