How do you change sparks plugs mercury sable 2002?

Answer 1

The procedure for changing spark plugs on an '02 Sable (DOHC 3.0L) is pretty much the same as on any other vehicle once you take off the plastic drain/airvent piece into which the windshield wiper arms go at the bottom base of the windshield just above the firewall. This provides enough hand room to get to the back plugs and the Coil. You may need to remove the coil and place it aside for best results. You will need to replace each wire one at a time (connect one side in the head the other on the coil) so you'll need the coil out of the way, but near enough to run the wiring. Recommend replacing the coil too if the spare cash is available as you don't want to have to get to that area again for a while and the life of a coil is probably close to that of the plugs anyway (as was mine - coil costs around $125). Some tips: get some never seize for the threads on the new plugs and use sparingly don't get it on other surfaces of plug (if you do wipe clean); use a small rubber tubing piece (3/8 dia) to help get new plugs started threading - it should be wide enough to fit snug around the metal contact on the top of the plug and long enough to fit down into the plug port - always make sure threads are started before using a wrench!; a torque wrench is advised to tighten (according to Haynes use 7-14 ft lbs); always use a spark plug socket (there is usually a little rubber padding inside to protect the porcelain insulator and to hold the plug in place and avoid cross-threading)- a long extension is necessary and can serve to help hand tighten without the ratchet handle; Replace the wires when replacing the plugs -removing the wires by pulling on the boot and twisting it loose - never pull the wire. Most of these tips are in the procedures for spark plug replacement in the Haynes Ford Taurus & Mercury Sable Repair Manual [2005, Haynes Publishing: Newbury Park California](the cost is around $20). NOTE: The manual doesn't show the removal of the plastic windshield wiper vent piece but the rest of the info is accurate. Actually the dealer said they remove the plenum rather than the plastic vent piece but that looks like more problem then it's worth. But either way works.
