Cost of coolant sensor???
 

Ok somehow, the coolant sensor on the driver side, under the exhaust manifold, broke. Thats the one for the temp. guage. The end is broken so that I cannot plug the connecter onto it. I can sometime get it on there to read the temp but i falls off in short order. How much should this sensor cost and how difficult to replace?

Easy to check yourself online at NAPA, Autozone, etc for prices.

Releive cooling system pressure, drain some coolant if you want, remove and replace sensor, refill and close cooling system and purge any air in the system.

Its 10-12 from dal/jason/sam or 20 from dealer. Take your pick.
