Engine Cooling problem
1996 GMC Jimmy 6 cyl Four Wheel Drive Automatic 145000 miles

my engine overheated so checked my coolant and it was pretty much gone. I then checked the oil dipstick to find out that my coolant had gotten into the oil. What to do? Should I drop the oil immediately? Is this a head gasket problem? Will I have to rebuild?

Hi there,

This is sounding like a head problem, I would get a head check done, this will detect exhaust gasses in the cooling system, a sure sign of head gasket or cracked head, but with the coolant in the oil I would be saying the head or gasket id faulty.
