Possessed underhood component: A common part?

Featured Replies

A few days ago after exiting the highway and slowing to the point that I could hear it, I noticed that this part was clicking and making noise.

You can feel it doing this. It hasn't had an effect on driveability yet. This in on an EA81T, but I was wondering if this part is common on other EA81 vehicles. Common enough that I could just go to the junkyard and get the part or if I have to start looking for a donor turbo car. I've looked at my books, but can't find definitive evidence as to what part that exactly is. This is where you come in. Is it one of the two connectors marked in red? Or maybe the relay looking thing marked in green?

Any help or insight you can provide would be invaluable.

Looks like a relay to me... No idea what it's for though

Maybe something to do with A/C. My 2 non-turbo, non-A/C EA81's does not have that looking part. While my A/C having hatchback has a similar relay that close to the fusible link box. Just a thought.

It is definitely a relay, not sure what for though....

Actually, I believe that relay is from the 3AT. I believe its called the "4WD-AT Checker." That's what it looks like in my 83 FSM.

 

I remember mine made that clicking noise too. I just yanked it, and it never seemed to have an effect on anything.

I can't seem to find anything in my FSM or supplement that comments on exactly what that part is. Where did you find this evidence?

 

I would love for it to be for the 3AT (Thats what I first thought it was), but I would like to be sure.

If you're looking for an EA81 turbo, check out the Smokey Point Pull a Part. I was there yesterday and they had an XT turbo in the yard (blue 2WD automatic).

Ed, XTs aren't EA81s... :rolleyes: Did they have an EA81T? I'll probably head out there tomorrow morning.

Well, if it isn't an EA81, I stand corrected. However, it said XT turbo on the rear trunk. Looked to me to be the 4 cylinder wedge. It was also a 2WD automatic gearbox.

Small update: I believe this part to be the Air Temperature relay. Once I have my hands on a spare, I will confirm.

Final conformation on the problem I was having: The plastic connector for the air temperature sensor had melted on the down pipe, shorting the relay. Sweet... Now I have a bunch of spare ATS relays for no reason.
