Smoking / Burning Coolant, can't find a source !FIXED!
Posted 26 April 2006 - 09:11 AM
I let it cool for a while, flipped on the defrost, and was on my way, the temp was fine until I got off the highway and had to stop at a red light, then it climbed, so I pulled over again, still smoking and there were small puddles starting to form under the car.
I let it cool for a few hours, and topped off the radiator, it took about 1/2 gallon. It sat overnight and the same thing happened again this morning. The temp gauge never made it to redline, but smoking.
The Radiator, upper and lower hoses, all look good. I can't find any obvious sources for the smoke. I called into work today, so here's my plan for troubleshooting.
Wait for all to cool, top off with coolant, more visual inspection. Find diagram of cooling system hoses, and check all. I have a cheap compression tester, so I'll try that after the hoses. After that I'm looking for direction. I'd really appreciate any help given. Thanks

Everything is cold now. I looked at all the hoses, that I could find anyway, and they seem to be ok. The hose from the thermostat housing to the top of the block pulled off easily on the block side when I tugged it, so I checked it and hooked it back up. I opened the housing and took out the thermostat, it's boiling as I type this.

I have been where you are.

mdjdc: I beleive I checked that one, but I will double check it. I saw on the hose diagrams the one that runs under the a/c compressor, and it looks awful to get to, so that may be last on my list.
Anyone have a good procedure to replace the hose that goes under the a/c compressor???
I'll keep you updated.

There is a small hose on the back of the throttle body and if that is cracked it will squirt coolant in the manner you describe the wetness. Check that hose and replace it. If this were my car, I would replace all of the hoses at the same time.
I sprung a leak in that little hose... while taking it off the second time I tweaked it just right so the pin hole opened and squirted water out.
If you don't know when the hoses were last changed... I'd strongly recommend you change all of them. I thought the hoses on my 91 loyale were fine... not too long after that the upper rad hose BLEW UP (6" long tear). Got to replace the water pump after that one.
anyway, that's my 0.15 (VAT included)

I Really HATE that Hose... is a 5/8" curved in 90º Hose, About one foot long. Goes to the Hot air system... it blew up long time ago... The correct procedure is to take off the Alternator and the A/C Unit... you don`t need to unplug the A/C Hoses, but be careful to them, to prevent A/C Gas leak, if it touches your skin, it will be a big problem, so be careful.
Change it with the very Best brand new hose you can find, and that`s it!.

mdjdc, whoozie: Is that the hose you were talking about?
I replaced the hose and filled the radiator again. I let the engine run for 20 or so min, and all was well. I took a test drive, things seemed to be good.
When I got back and opened the hood I did smell some burning and saw some smoke coming from the exhaust / cats. I think the excess and spilt coolant needs a few days to burn off. But I'll consider this a victory for now.
