    I'm looking at a used Honda crv, it keeps shredding the serpentine belt and has overheated. I have the AutoZone block test to see if the head gasket was damaged, will it work if the coolant isn't being circulated due to no serpentine belt? Once up to temp will the thermostat open and flow any coolant with out the water pump spinning? Thanks for any input.

    First need to know why its being shredded. Fix that then...do the test. Also could by a compression tester and do a static test.

    You can pressure test the cooling system. Then check compression in each hole as he said above. You need to fix the belt issue first. While it has no belt move every pulley and see what they do. In and out as well as spin. Also inspect the harmonic balancer and see if it is coming apart. If it has been ran hot the cost of the CRV would have to reflect the real possibility that the engine is toast.
