Where is location of the GEM module on 2002 Mercury Mountaineer? How long does it take to replace it? Does it have to be reprogrammed?

try a salvage yard that has an expedition or an f150 pickup and take the parts off and install in yours disconnect the negative side of the battery and you shouldn't have to have it reprogrammed

SOURCE: How do you access the spark plugs 2002 mercury mountaineer

IIRC these are a coil over design. meaning the coil is over the plug. the coil should have one 8mm bolt holding it on the lower intake manifold. remove the coild to get to the spark plugs. look by the fuel injectors, coil should be just next to it or very close. coil usually says motorcraft on it and circle in design.

good luck

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.
