Coolant Leak, Can't Find It...

[Psycron]

There's coolant on the crossmember (driver's side). Checked all coolant lines on the turbo, radiator and hard pipe, pretty much everything in the front of the engine. There is no coolant on the side of the block indicating a leak from the water pump (which was replaced when I removed the head). There appears to be coolant/oil on the driver's side inner axle between the axle boot and the transfer case. I'm guessing it leaked down from somewhere but I can't find the source. ugh!

I need some ideas. Where else could it possibly come from?

Check the oil cooler housing. On 91-94 DSM's instead of an air cooled unit to control oil temperatures, a water cooled unit is used.

Thanks for the suggestion. It doesn't look like it's coming from there, either

When I can't find the leak I fill the system up and run it. Under pressure it's usually obvious where the leak is.
