Engine Cooling problem
1999 Cadillac Catera 6 cyl Automatic 102000 miles
Hi I have a 1999 Cadillac Catera, I just had the Radiator replaced about 3 weeks ago because it had a small leak and was overheating, it started to overheat this real brown thick coffee looking stuff. It ran great for the last 3 weeks now its overheating within a mile of trying to drive it, so its parked now, one mechanic said it was the " Oil Cooler" leaking into the radiator leaking oil, that was the brown stuff and not letting the coolent flow thru. I just ran the water hose thru and unscrewed the bottom radiator plug to finally run that stuff out it was thick at first and not streaming very fast at all, got nothing but water in it now and took it around the street once and it was getting hot that quick, gonna open the bottom radiator plug again to see what comes out of it next, I just want to know if its possible/easy to bypass that oil cooler and to make sure that is what is causing that brown thick goo. I was told it was not a blown head gasket and there is no water on the oil dipstick at all.
