Hello,
'99 Saturn, SOHC, 112,000+
Car overheated, doing about the city speed limit, 35-40, heat gauge went all the way over, motor never knocked, very little steam when i raised the hood.
Looking at the engine, the coolant resevoir blew an oil like substance on the underside of the hood, and was oozing out of the resevoir container.
It smells like oil, has the consistancy of syrup, medium brown, not foamy at all. Checked the oil. Oil is clear, no foam, very slight condensation on the bottom of the oil cap while the engine was still hot.
After a half hour, put some water in the reseroir, restarted the engine, within 5 minutes heat gauge was up to the half way mark, (normally stays at the quarter mark), stuff starting oozing out again. Shut it down, mopped up the mess, walked home.
Im going to have the car towed to my mechanic on monday, i have checked the archives, looks like its a headgasket if im lucky, or a cracked head if im not. OR it could be some kind of lubricant that GM uses in their coolant system.
Anything i need to tell my mechanic to be aware off concerning this model Saturn ?
Thanks for any help,
Wiley
