?Cyl Temp Sensor

88911coupe · 06-28-2002, 07:28 AM

I'm putting in a new cyl temp sensor (From Pelican, of course) and I read the tech aritcle but have a question. I don't recall seeing any grommet inside the wheel well area to get the old one out. Did I misread it? Where exactly do I look for the grommet? Sorry if it's obvious but I did not see it.
Thanks,

It's not really in the wheel well. It's in the sheet metal at the front of the engine. You will approach it through the wheel well tough.

Read this thread I did (under old username) that gives some pictures and description.

Wonderfully detailed explanation (pics really helped) and thanks for the quick reply.

Buck,
Grease the grommet before jamming it in the hole. Life will be better.

If you grease, use silicon-based grease. Petroleum based will break it down over time.

I was wondering about what to use b/c I don't "think" there's anything on there now. I happen to have some anti sieze for spark plugs and that type of application...would it work?
Thanks,

I'm not sure about anit-seize. I just did it dry, no problems.

Buck,
I used vaseline as it was easier to push the grommet in the hole when lubed.

I mis read the comment. I was thinking about the threads on the sensor itself. Should I put something on the threads or will this mess up the readings for the sensor?
Thanks,

The sensor has a some stuff on it already, I believe it is thermal paste. You want to leave that alone.

I'm stuck...I can't get a socket wrench in there with enough room to turn and get the old sensor out. If anyone has a suggestion on how to get this out I'd love to hear it.
THanks!

Dude,

Know exactly where you are. I was stuck too during that phase and I had the engine out. This is what I had to do:

1. cut the wires so I can get a socket in there
2. Use the socket (6 point), or a brake-line wrench
3. Still ended up breaking the damn thing because after 100K miles of heat, it was welded in there.
4. Took the head to the machine shop and have them burn out the left over pieces of crap inside the hole, and rethread it with 1/8 pipe plug tap (craftsman tap-die set has one in it)

My suggestion: heat it up carefully with a torch if you can, if it is still inside the car, you may have to remove the metal sheet metal to have enough room. I do not remember if this is doable with the engine in the car.

In short, your easy 1 hour project has turned into a week-long project, and maybe the engine has to come out. Sorry dude, no good news here.

Finally got it out...went back out and got my hand in there and managed to get my other hand on top and get enough force to break it loose. Getting those grommets in place was LOTS of fun too.
