Hello folks!
I was looking to confirm a possible HG failure
car overheated this morning (first time ever) while cresting the hill upon which i live. First noticed no heat comming from vents, and then saw the temp guage headed towards HOT.
Pulled car over, and shut down. NO coolent out tail pipe.
noticed, however, BLACK sludge/oil in coolent overflow. no bubbles, just black ooze. Coolent low in radiator, but no sludge noticed
car has 125k
Is it what i think it is??
any help would be appreciated.
