Coolant Leak, Need Help

[outrun]

I am losing about 1 pint a week. I cannot figure where this is coming from. Looks to be behind the engine. Car runs fine. No issues or anything to indicated head gasket failure. Anyone have an idea where this might be leaking from?

I thought that was on the passenger side. If thisbis the heater core is this the type of thing that will just leak or do they blow out?

Cracked or worn heater hose. Loose hose clamps. Gotta look real carefully on the passenger side of the engine compartment. It could also be coming from the front of the motor somewhere and travelling down the block or oil pan before dripping onto the floor. If you have the 4.6L just hope it isn't the dreaded oil filter adapter gasket. You might want to invest in some UV dye and a black light if you can't see anything obvious.
