Common Coolant Leaks

I'm looking for any help I can get to find a coolant leak. The symptoms I've noticed so far include:

Coolant on the front differential and crossmember. A two or three day leak down to "low coolant" which has been getting faster. No engine overheating.

I'm at 235,000 miles and I doubt the water pump has been serviced, do they have a weep hole to indicate bad bearings?

yes, they do have weep holes the water pump is on the driver side of the engine I'm sure u know that, sometime the oil coolant tube that runs from the water pump to the oil filter housing can leak which will appear that the water pump is leaking, I hope my 2 cents help..

I have a leak right where the head meets the block on the front right of the engine. If I run without a rad cap it stops. The coolant system does not get pressurized so im no that worried about it. It will get done when I do the headstuds eventually.

Water pump or rubber hose just behind the balancer.

After looking around I think the leak is coming from somewhere around the thermostat housing. The area right below the turbo coolant tube appears to be wet, which is right below the themostat housing, are there any o-rings or anything on the tubes between that housing and the water pump?
