Spark plugs replacement


twist each plug wire boot before disconnecting dont pull on the wire and do one at a time so as not to misswire them. get an airhose or bicycle pump and blow out the sprak plug hole before removing them, particles could fall into the holes after you remove them. Also remove only when engine is cool or you cold damage the threads on the heads. You'll need a padded special spark plug removal tool that will fit at least a 3/8 drive ratchet wrench, and you might need a 4 inch extension for the ones in the rear. Spray some penatrant oil let set for about 5 minutes and try as hard as you can to be at 90 degree when trying to bust them loose. The plugs you purchase should always be stock... NGK is a good brand and they come pre gapped, but line them all up and look to see if they are all the same gap,if not then check the gaps. i always put some oil from the dip stick on the threads to help on installation. dont torque these down!! snug up with fingers first, then snug up with socket, then give a 1/4 to 1/2 turn a little more than a quarter turn is usually good enough to insure the crush gasket is sealed. put new plug in socket and use as guide make sure you dont cross thread! if its not going in easy with some wd-40 or oil then something is wrong and you got it at a slight angle try again. now put on plug wire make sure you hear or feel a little snap or click... that will let you know you got it on correctly, there you go now only 5 more to do and your done. when all is done and you didnt drop any of the plugs on the ground. the engine should start up real nice. but if it sounds weird then its wired wrong. follow the diagram on your hood it should show you the fire order routing from the coils. can i get a very helpul on this one thanks!

Spark plugs difficult to replace


The engine does need to be shifted to replace the rear plugs, but it is easy. Take out the dogbone engine mount in the front of the engine compartment and push the vehicle backwards while still in park , then throw the parking break on once the engine tips forward.
