Automotive Expert
have you verified the fan is working ok ?

The fan is connected to the crank shaft
Automotive Expert
I understand that but is it working ok ? it should accelerate in speed if you accelerate as well and fan speed speed up, with vehicle off there should be some resistance when spinning by hand if it freely spins the fan clutch is bad

Oh yes it has regular resistance.What else do u thinkHello
Automotive Expert
you will need to check for a blown [head gasket](/topics-head-gasket-chevy/) next use the test from autozone you can rent

What does the [water pump](/topics-water-pump/) test consist of
Automotive Expert
there really is no test for that, you would want to pull it and check the fins if they are in order its good you should be able to see the coolant moving in the reservoir when accelerating as well

Yea with the cap off before it Completely warms up you can see it moving in the reservoirWhen the coolant lines come out and go in the [heater core](/topics-heater-core-chevy/) it branches off and goes along the inside of the frame to the back of the vehicle where is it going
Automotive Expert
that one im not sure on I would need to follow the house to the source to verify that
