2002 GMC Safari Question: lower Intake manifold gasket replacement



, San Leandro, CA, December 27, 2010, 11:11

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.

    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.
