I have another topic going that I have had to let rest while I fix this one.

I have a coolant leak on this 93 SSE near the TB. From all the posts about the LIM and UIM leaks, those are on my list to check. But this one almost seems to be coming from further out. I have even had it drip a little on the exhaust crossover pipe above the transaxle.

Question: Is it common to get leaks between the UIM and the TB?

I see on some engine drawings that coolant runs through the TB to help cold starts. I've tried checking with a mirror, but can't figure out up from down enough to see anything. I'm looking at trying a TB gasket tomorrow.

Thanks for your feedback. I had abdominal surgery a little over a week ago and my wife has been using a stick to keep me from messing with it. But I think the DR. will release me tomorrow and then it'* back to skinned knuckles.

I had the same thing last year, it turned out my UIM gaskets were shot.

I found some weirdness with the front lower stud of the 3 that hold the TB to the manifold. The nut that is sort of embedded in the back side of the manifold(for that stud) was slightly loose. After getting the throttle body off, sure enough, there were signs of leakage on that stud and in a cavity where there shouldn't be; also signs of coolant leak on the bottom.

Whether this is all of the problem is yet to be proven, until I drive it more. So far, no coolant leak that I can see. Will update when I am more sure.

BTW, there are a few fasteners that are boogers to remove to get to the final 3, esp. the front lower nut for the TB support/brace. Also, the manual shows a fiber gasket and this one is actually the rubber style like on the LIM, etc News at 11.

Take a flashlight with you the next time you try using a mirror. Shine the light on the mirror; it will reflect the light to the part, illuminating it, making it visible in the mirror for you to see. It is a neat little trick.

Thanks. Yes, that is what I have been doing; a large, extending dentist type mirror and a mini-mag light (so I can hold it in my teeth if I need an extra hand). My problem was that I was not familiar with the layout of things up under there. So you tend to lose perspective with what/where you are looking.
Regardless, that is good advice for anybody on here. Thanks

Let me totally jinx my repair job by saying it looks like the TB gasket was the culprit. Today, no leaks, drips, steam, or "accidents on the garage floor" after my test cruise. I count myself fortunate.
Thanks and now to my other (epic) post about the pesky code 42.
