How do i change sparkplugs for 2002 mercury couger v6
To remove the spark plugs, remove the covers and you will see how simple it
really is. The spark plugs are hiding under the covers.
Not only you will have to lift the covers, but to reach the back three
you will have to remove the valve cover. Here's how to:
1. Remove the
water pump belt cover (the black cover in the front of the engine
compartment that has ?Duratec? on it.) If you have a 1996+ vehicle, you
should think about removing it permanently, since it only serves to trap
heat and slowly kill the IMRC box electronics.
2. Disconnect the following electrical connectors from the: MAF, IAT,
TPS, IAC, and EVR. The EVR connector is black and is located at the very
back of the upper plenum, next to the firewall.
3. Disconnect throttle cable from the TB and the cruise control cable,
if equipped. For 1995 5-speed vehicles, take care not to lose the metal
clip for the throttle cable when you are removing it. Once the cable is
removed the clip will slide right off.
4. Disconnect the vacuum lines from the EVR. You may have to wait until
the upper intake is unbolted and partially removed for better leverage.
5. Disconnect the vacuum lines from the top of the upper intake. Push
down on the black plastic collar with a screwdriver and hold, and then
pull the plastic line out of the intake.
6. Remove the air box along with the MAF and accordion tube.
7. Unbolt the throttle cable bracket from the upper intake (three 8mm
bolts, one 10mm nut). Set bracket and attached cables aside.
8. Disconnect the air bypass hose at the upper intake. It connects right
next to the IAC valve.
9. Disconnect the hose from the PCV valve that goes to the upper intake,
underneath the throttle body. This is also a good time to change
the PCV valve.
10. Unbolt the EGR valve from the upper intake.
11. Unbolt the upper intake. 12. Carefully remove the upper intake and
set it on top of some clean rags or newspaper. It will likely be oozing
some oily gunk out the bottom.
13. Cover the openings of the lower intake with clean rags to keep
anything from falling into the openings. Anything that falls in will
likely end up in the head or the cylinders themselves.
Now you are free to remove the back plugs
