I have 100K miles on my 2000 CLK 430 -- I haven't worked on a car in many years. Are the plugs accessable and what else should I do ?? New Plug wires ? New gas filter ? or What ?


Thank You

Allan

I just changed the plugs on my 99 CLK430. It wasn't impossible. It took some universal joint adapters and some different extensions to get into the tight spots. I used an open-end wrench to get the spark plug wires off the plug. I took each coil off. I put anti-sieze on each plug and torqued them to 18 I believe. The hardest part was putting the plug wire back on the plug. It just wasn't easy to get them on at the right angle and then I wasn't sure if they were all the way on so I used a couple wrenches to push/leverage them on as hard as I could. The gap was set at 40 from the factory (got the plugs from Phil at Fastlane). I could really tell a difference in the acceleration after the plug change.

Guys, spray a little wd40 inside your plug wires before installing them. It makes things a heck of a lot easier getting them to snap onto the spark plugs. It also helps to keep moisture and corrosion out of the plugs and wires.

That's a new one on me, I've always recommended dialetric grease because of its neutral properties (non-cunductive). Is WD-40 the industry standard used lube for plug wires? I'm asking because I'm just curious.

Thanks,

Dale

That's just something I've picked up from the old timers that work in my dealer. Seems to work great and I've never seen any problems with it.

WD-40.

Eats rubber and viton.

I use a little graphite powder on the boots before installing them. Have been doing it for years. It doesn't pick up moisture and is very slippery.

everything else was straight-forward, but i could not remove the last plug connector on each side, closest to the cabin. there is very little room and i could not get any leverage to pull.
