Spark Plugs

Hey guys, semi-n00b question here. My sister has a 97 Wrangler with the 2.5L 4-banger. I've been trying to change the spark plugs but on the one closest to the radiator, there's really not enough room to unplug the cable easily. Can/Should I remove the alternator (I think that's what it is, at least) to make it easier or is there a better way?

hmmm, i have a '97 2.5L and had no issues removing that plug a couple weeks ago.... maybe a 6" or 12" extension on the ratchet would help out. I think I ended up using one if i remember correctly. Shouldn't be an issue getting it out though. you could also remove the plug wires, or even remove the air intake. that could make it easier. all you need to do is loosen two flatheads.

Here's a picture of my situation (I circled the plug wire I need to get to). The problem isn't really getting down to the plug, the issue is getting the wire out because the alternator (I'm assuming that's the metallic thing in the bottom of the picture) is too close. I already have the air intake off.

I do have A/C and that may be it. Any other ideas?

go to tool store and buy a u-joint socket. this will allow you to get into the tight space. i had the same problem with my 98 4.0L. i did not want to take the belt loose and move the ac pump. here is a link to a pic..

Don't pull on the wire to remove it, you'll break it inside.
Get a plug wire puller - most any auto parts store has them - a hooked device to grab the bottom of the boot so you can pull it without damaging anything. $3?

Use the universal socket or an in-line universal to unscrew the plug. If the universal flops too much, wrap tape around it.

Put anti-seize on the plug threads - just a dab.

Installing - slip a short piece of vacuum hose over the end of the plug, use that to get the plug started in the hole.

Then the universal/wrench to tighten it.

Position the wire on the plug and push.


It's no wonder the country is falling apart - stupidity abounds!
