Re: Underhood light

Is it permanently attached, plug into the cigarette lighter, or some other connection type? Any idea on the approximate year range of the vehicles it's found in? Would it be a glove-box item, or is there a particular storage space for it?

The base is permanently mounted under the hood of full-sized GM pick-ups, at least through the '70s-'80s. The light itself can then detach from the base, but remains connected by the ~20' cord spooled out by a reel on the base. The light has a magnetic bottom that you then stick wherever needed around the vehicle.

I've seen on Jeepster sites where they replace the mercury switch with a toggle and then mount the base inside, using it as an interior light while retracted but still able to be placed anywhere inside or out as needed.

Ah, so the "storage location" is under the hood, attached to the magnetic base. Neat, never noticed these. But then, I haven't had much reason to go looking under the hood of GM trucks.

Right, but the magnet is on the light itself. It stores in a clip on the base, or I've seen some that have a plate the light sticks to when stored. I'd trust the first method more.

Here's an item that might be helpful.... It's a 2-bung, 3/8" NPT in-line sensor holder, with 5/8" in/outlets, just as is widely used on the XR. Source vehicle:
Early 90's 1.9 Escort

The fitting can be found about dead-center behind the engine, in front of the false firewall. The coolant hoses have permanent band clamps, but they're easy enough to cut off, revealing typical 5/8" barbed ends.

Pulled one of these out of a 91 GMC Sierra, the durn cord is 20ft long and has a magnetic base (weak albeit) but its great for little jobs where a small light can be positioned nearby.

They came with all models of teh above truck from 88 to 92, or otherwise that same body style, idk other donors.

I put one of those under the hood my '70 Mustang a few years back... very useful, especially on cars that know how to find the darkest spot on the planet to break down.

It could be the locking eaton differential, which is OK, or could be a positraction differential (better for us). The posi will usually be in cars while the locking differential will be in trucks. You'll want to verify the spline count. Early vehicles had 26-spline, which is what we want, while later models will have 28-spline.
How do I tell the difference between the 2? I don't wanna have a locker laying around that I may not use...

mid 80's 300ZX NON turbo intake pipe.

its a quality, constant diameter 3" pipe made of heat resistant tough plastic that has a coupler that fits PERFECTLY onto a big VAM. Like its made for it. There were at least 2 in my wreckers. Well, now at least one.

Also an older (early 80s) Saab 900s oil cooler. Its a nice small air/oil cooler with good quality piping. I use it as a power steering cooler for my Talon and have for many years, no problems at all.

Also, a request? Can we maybe have another non postable thread where once a week a moderator can get all the confirmed parts and post them, so when one is going to the wreckers, you can just print off that message and not have to go thru 5-?? pages? Just a thought. Maybe down the road, someone can add a description to each part. I know thats a lot of work but some of it is already done, thanks to Brad and others.

Good call. I've actually used one of these, slightly modified, for years. It's even got a mounting boss built into it, which I also use.

Good idea - a similar thought has crossed my mind as well, which is why I troll through this thread every now and then and clean out the useless chatter posts.

But perhaps what I could do is update the first post every now and then to contain all the net/net info extracted from the ongoing discussions. Feel free to remind me....

I had been looking for a similar part. One had a 3/8" port and the other was slightly larger. I thought it was off a mustang but I couldn't find it.

The other day I noticed the part you mentioned in your post about the Escort. However today I went to a different junk yard and found a triple bung pipe on a early 90's Escort with a 1.9. I found them located on the drivers side under the coil pack.

The double seems to hold a green ring sensor similar to the XR4ti purple ring sensor. Also has what looks to be ECT. 2 prongs. Grey on outside and orange on the inside.

The tripple has what looks to be ECT. White ring sensor and something I have never seen before. It's simmilar to the ECT, ecept the brass arear is much larger and the plastic is green on the outside and orange on the inside.

Any idea if these are ECT. Are the cross compatable with different ECU's?

Not sure, but the 3rd could be a fans switch...

As Johnny suggested, the third one might be a fan switch, although generally those disappered from many cars in the 90's. It might also be a flow control valve, preventing warm coolant from reaching the heater core during warm weather.

Check the resistance on that ECT and compare it to the older style (the stock one found on the 2.3). My guess is that they have the same output, but clearly it's something that needs to be verified.

FWIW, the 2-bung unit I got out of the Escort has a purple-ring gauge sensor that looks identical to the infamous one used on the XR. No luck though - the resistance curve was totally different. :x
