A Few leak questions

[87Superdupra]

So I got my car diagnosed by a shop as opposed to feeling around in the dark about problems. thought I had a BHG because of occaisional coolant smoke and oil smoke out of my exhuast.
They said that the coolant was a leak in my throttle body somewhere and that they would have to R+R to locate it. Any ideas what Area that could be from, Throttle body Gasket? I just want to be able to order the part before I take it apart.

R+R? reading and relaxation? lol Hope it's R&D!

Check out the online supra TSRM and start reading about the cooling and intake systems. Empower yourself against that R+R crap dealers will charge you for

best bet is the isc. theres coolant hoses that run into that and the tb to heat that mofo up. and when they deteriorate, they become a major pita as well as a coolant leak.

I 'by-passed' the coolant feeds into my throttle body about 4 months ago. I just pulled the hoses off it, and put them together with an 8mm (5/16") brass pipe and hose clamps.

I did it to have a 'cooler' throttlebody for cooler air intake. I like the performance much better now.

If your leak is in the ISC, you can by-pass the coolant , same as I did on the throttlebody, but you should probably get a new one.
