Since the problems never end on this car, I have discovered a coolant leak. It had a bad radiator cap, so I replaced it. The previous cap was a 13lb cap, the new one is the 16lb cap that was shown as the correct cap. Now I noticed there is a leak to the upper left of the water pump, below the thermostat housing. It appears to be coming from behind the water pump, not the actual water pump. Did some reading and have read it could be the timing cover gasket or a bad water pump. Just wanted your guys opinion on what I should replace and how hard it will be to do.
