2002 GMC Safari Q&A

2002 GMC Safari Question: lower Intake manifold gasket replacement

My van is losing coolant and I believe it is going into the motor oil. I do not see any outside leak. I was already told that it is going into the oil. -
Answer 1
Don't drive the van with contaminated oil. The coolant will destroy the bearings! We should pressure test the cooling system first but I would also want to make sure your headgaskets haven't failed. Vans are difficult to work on because of the location of the engine. Good luck and happy holidays. -
