rojopojo Posted December 3, 2010 Report Share Posted December 3, 2010 I was given a 1989 Devile 4.5 fwd I drove it home a few houses down the road with no problems. I left the car running and got out to do a walk around and I noticed there was water coming from the exhaust. My first thought was a blown head gasket but I've never worked with a caddy before I know some GM cars run coolant threw the throtle body. Any thoughts or ideas will help thanks.

Ranger Posted December 4, 2010 Report Share Posted December 4, 2010 Are you using coolant? Are you over heating? If the answers are no, it's probably normal condensation. Link to comment Share on other sites More sharing options...
heitzman Posted December 6, 2010 Report Share Posted December 6, 2010 My 96 Deville does this when it doesnt get ran for a few days, Its normal if your not loosing coolant like Ranger said. Link to comment Share on other sites More sharing options...
BodybyFisher Posted December 6, 2010 Report Share Posted December 6, 2010 I am not 100% sure, but the 4.5's intake manifold gaskets were not as prone to leaking as the 4.1 (HT4100), if that is what you are thinking about KHE (Kevin) is knowledgeable about these engines, I am sure he will provide his knowledge Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

KHE Posted December 7, 2010 Report Share Posted December 7, 2010 The 4.1/4.5/4.9 engines are not known for head gasket failures. If you are not going through coolant and not overheating, it is most likely condensation.

the gold2 Posted December 22, 2010 Report Share Posted December 22, 2010 ditto, condensation is quite normal. observe other cars and you will spot the drips and puddles under the tail pipe... Link to comment Share on other sites More sharing options...
