Engine/Transmission (1998.5 - 2002) Pressurizing Oil Cooler

[turbo torque]

The other day I was out of town when, I think I blew a head gasket. Cooling system full of oil. Last issue of TDR has an article about the oil cooler possibly leaking, so thought I would check that first. When I pulled cooler there was a couple gallons of ugly gray matter that drooled out of the block.



Question is, How do I pressurize the oil cooler? It is sandwiched between the block and oil filter housing, with no way to hook air to it.



Thanks in advance for any input... Bill
