Having problems with your 1988 Buick LeSabre ?
I can't get the spark plug wires off. What's the shroud covering
\015 1) There is a metal shroud covering the spark plug ends that slides up and down. Is this a heat shield? Are they connected to the block? 2) I have attempted to pull the spark plug wires off of the spark plugs. No matter how hard I pull, the wires won't come off. I've tried to wiggle them and pull as well as twist and pull, to no avail. I have never run into this problem with any other vehicle.\015
I just removed 3 front spark plugs on my 2002 Buick Lesabre. They had heat shields. It took me an hour. Unbelievably hard. I pulled, twisted wiggled up and down and side to side. Also I sprayed wd40 into the base of boot. Finally they came off. I reused the wires and shields and the car runs tremendously better. 109,000 mi plugs never changed before. I used Denso twin tips.
I have - many times they are heat fused you need to just get ready to buy new wires you probably need them anyway. Put on a pair of gloves and tear those babies off there is no other way. If you have to get a pair if pliers etc and grab and tear. Don't damage those metal shrouds because they are heat shields and on this particular motor you need them. Take away ant debris and get ready because the plugs are gonna be tough too I bet. I suggest a short breaker bar to break then loose but be CAREFUL because you don't want to break one off in the block. Just get a perfect fit on a spark plug socket and don't mess around with one motion break them free. They need to be changed. Hop this helps. Good Luck
