I have the V-8 version but have found the easiest method is to gain access through the rubber flaps just above and behind the front tires (inside the fenderwells). I simply pull out a few plastic clips that allow the rubber flap to be pulled aside and use a socket and exstention to reach the plugs. Afterwards, simply put the rubber flap back in place and push the plastic clips back into their holes.
how to change spark plugs on a 97 mercury mountaineer
firing order for 2000 mercury mountaineer with a 4.0, v-6 engine
jack up car and change plugs from behind each front tire.
On my 2000 Mountaineer, One side is accessibly from top. Other side, take off wheel. take off mud covers and access was easy. Not sure if this will be helpful on 97.
The manual will state when to perform tuneup.
Hello I had to remove the curtains from the inside of the front fender wells to access the spark plugs on my 1998 Mountaneer. Be prepared to replace the curtains because most of the clips will break when removed. Hope this helps.
the library should have a shop manual for this vehicle, you can make copies of the right sections :)
( 6 ) if you have the 4.0 liter SOHC , V6 engine and ( 8 ) if you have the 5.0 liter , V8 engine
To change the spark plugs, the ones on the left side (driver's side) of the engine are accessible from the top of the engine under the hood. The plugs on the right side (passenger side) are accessible by pulling the right front wheel and removing the rubber dust cover (pops off) that attaches to the fenderwell. This is assuming that you have a 5.0L V8 engine (302ci). Have Fun!!!
K in the fender wells if it is a 5.o l they are left and right of cyl head under exhaust headers
Pull off the upper intake plenum and you will have access to the plugs and wires.
Check your connection or ground wire. Also check your spark plugs
