Looks like water is leaking out of the right side of timing chain cover
I go to the adventure park in glenwood and we were there for the hole day. And I come out and i seen that it had started leaking antifreeze. So I get underthere and it looks like my water pump was leaking. But my coolant level was fine??? I drove it from glenwood to carbondale jusy fine with no overheating or even getting close. Is my water pump going out or what?
Loss of antifreeze /water from leak at water pump causing overheating.
simple to replace just be carful getting the new gasket on there properly.
5.7 litre or a 350 engine
replace water pump
Water pump replacement requires removal of the fan belt,fan shroud,radiator(for extra room),fan and clutch fan assembly,possibly some pulleys and belt tensioner,and finally the water pump.Oh, and as always remove the ground cable from the battery.Possibly the positive cable too.
after turn off water drips from under the hood. It's not fixed yet,because it needs a water pump.
It leaves a tell tale "wet spot" in the driveway where I park. If coolant gets too low, it will overheat as indicated by temp. gauge or "idiot light".

Th Fix....Replace the water pump. Consult your Shop manual for details.
