Sometimes coolant blows all over under the hood when an engine overheats. Try to find out where the leak is comming from before making any assumptions.
The head gasket on a 2004 Kia Rio is replaced by draining the coolant, removing the intake manifold, and unbolting the cylinder heads. The head and gasket can then be removed and a new gasket put in place.
The head gasket on a 1999 Chevy Malibu is replaced by removing the coolant, intake manifold, and retaining bolts. The cylinder head can then be removed, the gasket replaced, and everything reassembled.
intake manifold gasket if it is coolant in the oil
I would suspect the manifold itself is leaking around the cooling passages. It will need to be removed and the gasket replaced.
The intake manifold, head, and exhaust manifold must be removed to gain access to the gasket.
A blown head gasket can allow coolant to see into the manifold, and out the exhaust. A broken piston ring can also cause this problem.
you need to replace the intake manifold gasket.
a bad head gasket or intake manifold gasket.
You either need a head gasket or intake gasket.
Blown head gasket and/or cracked head.
In general, yes a coolant leak in a 2002 Bonneville can be fixed. The issue whether it is worth the money to fix the leak. If the coolant is leaking from an upper or lower coolant hose, the repair is simple and inexpensive. If the coolant leak is from the radiator, it will be a bit more difficult and/or expensive to repair. Moving up the scale, if the coolant leak is coming from a manifold gasket, it will be still more expensive. Likewise for a coolant leak from the heater core. And at the upper end of the scale, if you are leaking coolant from a cracked engine block, you're looking at replacing the engine.
There is coolant on the ground occasionally. How will I know when the intake manifold gasket is leaking
