Re: No pressure in upper radiator hose. Is this normal?
I'm having the same problem on my 84 c10 I was under the impression my water pump maybe bad but there's no water leaking anywhere not in the weep hole or any where else, I've already changed the thermostat a d the upper hose the fluids in the radiator are up. My temp gauge will shoot up to about 230 the drop to about 170 /185.
