Spark Plugs on 99

[DRW1000]

Besides the difficulty in reaching the rear plugs has anyone had any real problems replaceing the plugs on a 3.8 ('99)?. I am going to attempt the first change at about 130000 KM and I am worried that they may be seized. Does anyone have any advice?


Thanks

My suggestion is to get to them from underneath. You can actually see the plugs and can use an extension, if necessary. I was worried about mine being seized too, but they came out easily. I wasn't comfortable using the bend over the intake and feel method...

Make sure the engine is stone cold... to help minimize the chance of galling the heads.

okay. I am glad you mentioned that. I was thinking of warming it to expand the alluminium head more than the spark plug.

I also have to admit that I do not know what galling means.

I heard that anti-seize is NOT to be used.

I may be doing wrong, but I alway use dry molybdenum disulfide powder (similar to graphite) on spark plug threads.

I've heard that too, but still have been using a tiny dab of never sieze on plug threads for years without issue. From what I understand the fear is of 'over tightening' the plugs when never sieze is used. I just snug them with a standard socket wrench & have been good to go.

Over-torqueing plugs is a serious issue. One poster in cartrackers.com posted that he torqued his plugs to 87 foot-lbs ... "just like Ford recommended". I seriously doubt it. 87 INCH-LBS maybe I could believe.
