WTF, will this thing quit breaking? I've got a water leak, it's not spilling out but it is a fair dripping leak. Looks like I need to add coolent about once weekly. The water drips from right around the fan area of the front of the motor and seems to me more previlant during idle then operation, but I can't even being to validate that last assumption. So I haven't taken a decent look at it yet but I'm guessing the water pump seal? Do I need to replace the pump as well (it's at 160K miles), or is the seal good enough?
