2003 mountaineer V8 Temp gauge jumps to hot not over heating. Replaced thermostat, no change


The Engine Temp. sensor is bad. it is under the intake manifold. if there is a miss also check under the coils over the spark plugs. If there is Coolant in the spark plug holes .then the intake gasket is leaking. The intake manifold needs to come off to change the coolant sensor. When off look for corrosion on the cylinder head at the coolant port. If there is corrsion then the cylinder head must be replaced.

I own a 2004 Mercury Mountaineer, and the ABS light will come on after traveling about 20-30 miles on the hiway. It goes off after sitting over night and is fine around town and doesn't come on.


On a Car like that you have little sensors on each one of the wheels. These sensors are small, delicate and finicky. You probably have a loose one or when the wheel heats up or reaches a certain speed, highway driving, it loses the connection and the light comes on.
The best way to fix this is go to a shop. Since the answer lies in the computer somewhere they need to check it. Note that the computer on your car stores the data when this happens and they should download the stored data if everything " seems fine ". Hope that helps
