Slow anti-freeze leak in front of trans/behind engine
Hey guys,
I have a 1992 Camaro RS 3.1 V6 Automatic and just had the coolant system flushed and refilled about a month ago. I have discovered a leak of antifreeze between the trans and engine. I noticed this after I jumped a curb, but thought this could have been there already because I smelled something burning (coolant on outside of engine???)after getting the coolant changed. I sprayed the bottom of the car off so that all the residue from the coolant went away, and that would therefore let me see if it would build up again. After a week, it has and that means the leak is still there, besides, why would it go away? My question is what is this leak coming from? Its rather slow, and can it be fixed cheaply? Could it be a coolant line rotted because of the fishy smelling 2+ year old coolant that was there before the flush? Let me know what you guys think so I can quit leaking!

Sounds like a plan, my neighbor also suggested a "freeze out plug" could be gone bad on the back of the lil' 3.1 Block. but he said that would make it shoot more. I'll look tomorrow.

preasue test it. that ought to let you look around the engine while it's cold, and under preasure. might be a head gasket. no idea if there are freeve plugs on the back of the 60* engines, there aren't on SBCs or 90* V6s.

Another thing to consider (if it's in the area), there is a block drain plug on the side of the block towards the back of it. on a V8 it's on the drivers side.. When you do a coolant flush you un screw this plug to drain the coolant from the block. If they did't use a proper sealant material when putting it back in, it may leak.

ede is mistaken (which is not something that happens very often!), there are actually 2 freeze plugs on SBCs on the rear of the block. If the coolant isn't coming from above (heater connections, intake manifold, head gasket, etc.), and if the 2.8 has the same thing (I suspect it does, casting processes being what they are), you have a fun job ahead of you.

Yeah that could be very bad. My neighbor might be able to help me out. Could be the drain plug that you said because it never leaked prior to the flushing of the system. I could have knocked something out of place on impact though. The heater core lines look fine, i checked them today and could clearly see some nice clean fresh lines on there. I really hope its this drain plug, and not a freeze out plug, I could smell something burning on the way home from the mechanics that day. Hmmm....
