t-stat wouldnt cause it to overheat in 5 minutes. definately sounds like the coolant isnt full. I cant help you with a pic, but i'd say your on the right track.

Look for the 3/8" line at the side of the surge tank near the top. That's the purge line.

Whats the silicone for? Except for their use in fake boobs, silicone has no place in a Cadillac.

Hope that solves your problem. Let us know.

I remember our old Guru saying that silicone is instant death to the O2 sensors.

There is a direct proportion between Caddies, silicone, and boobs. Believe me.

Silicone is to seal Vacuum line connection I broke on top of TB. I Started car and let it run for 30mn. Temp got to 223 then went down to 217. So i think I'm ok for now. Any one know where i can buy that Rubber part on top of TB.

Samsix, The vacuum connector on the throttlebody - did it slip onto a metal nipple ? If so, you can replace the entire plastic line and connectors with a piece of the proper size rubber vacuum line, available in blister packs at any large parts house.

Otherwise I'll bet you're in the junkyard search business............

How do you purge line?

Unless it is clogged, it's self purging. Just start the car and run the RPM up to 3-4K a few times.
