So I think I diagnosed my problem as the WP
Symptoms include loss of coolant, overheating after extending periods of time due to the loss of coolant. Just replaced thermostat, water pump temp sensor, so those are assumed to be good.
I can see the coolant loss. It doesn't do it when the car has not been run, but once it begins to warm up some, it begins to drip. The drip travels though, so it is hard to tell where it is coming from. It is a steady drip. I cannot reach around the back to feel or see the weep hole, however, I can tell that the drip is rolling down off other parts. Basically, it looks like it rolls down part of the water pump and then down what looks like another bracket or something, near the PS/Tensioner pulley.
I can fill it back up, but of course, it keeps losing coolant the way I just described.
I have a bad water pump?
Time for a new pump (or an electric one...
)!
