changing spark plugs

[oldtomjeep]

OK, this is the dumbest question I have ever asked.................

I have worked on cars and engines since I was a kid, but I cannot find the plugs on my 3.7 V6. I would usually expect to find plug wires leading to plugs; nope; no wires. I'm not surprised at not finding a distributor, that's fairly normal now. All I see is a ********* cover that looks like a valve cover. Are they under there?

The whole things makes me feel like an idiot. (OK, not the first time).

Thanks, Prof! I'm pretty sure I never would have found them.

Get yourself a 12" length of 3/8" fuel hose. When the plug is backed out, push the hose over the porcelain part of the plug and finish loosening/lift it out. Reinstall and hand tighten the plugs the same way. Spark plug sockets have a rubber boot up towards the top to hold the plug, but over years of use, they lose their grip.

My favorite is this video!

Don't forget the other spark plug locations! :icon_lol:
Even though in the above video he uses platinum, the Jeep prefers regular copper cores like the NGK's listed on the under hood sticker or Champions work well too. :gr_grin:

The one in the antenna is easy to miss. :gr_grin:

Do not forget to vacuum or use a air gun to get all the dirt out of the area around the plugs, as you do not want dirt in your engine.

A dab of anti-seize on the new plug threads will aid mightily in removal the next time around...plug #6 is a LOT easier to service if you remove the 10mm nuts on the coolant reservoir and swing it out of the way....

 

[uss2defiant]

the NGKs threads are plated to prevent seizing between dissimilar metals.
don't think anti seize is needed anymore.

I still wouldn't dare do plugs without it. I have had plugs stuck in a f350.... not fun
