dont know of any head gasket concerns, usually when the intake manifold leaks it either split and pours out or the heater hose fittings crack and leak. Check the hose connections at the intake and make sure none of the hose clamps have cracked and are leaking

There is one for the 2003 Mercury Mountaineer. If you are smellign a "vinegar" odor, mix a solution of 1 part bleach to 3 parts water and pour it down the grid at the base of the windshield. It will take care of the smell.

SOURCE: engine not getting hot check engine light is

The two things may be related. You need to have the OBD II code read to determine what the trouble code is. Most auto parts stores read these codes for no charge.

A car in which the coolant does not get hot enough likely has a malfunctioning thermostat. Thermostats are cheap and easy to replace.

i would check the throttle position sensor first, check for vacuum leaks, egr valve, i read a few things were people talking about a o ring under the separator. which is under the intake manifold. i would check the easy ones first before pulling your intake manifold off

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.

That could be a bad lower intake manifold gasket. Have it checked by a mechanic as soon as possible; left unfixed, it could quickly destroy your engine.
