running hot

headgaskets was replaced,the owner putted a new raditor on it,the mechanic took thermostat out of it,it runs hot y driving at 45mph..new water pump anw new raditor cap

first of all, no thermostat will blow head gaskets. you must have a thermostat for the system to work. how about the fan on the water pump?? did anyone do a leak down test on the cylinders to confirm your gaskets or a cracked head?? I would start from there and move forward. I would not return to the guy that took out the thermostat. Roy

the fan is working and there no leak.what else can we check for

That may be the fastest leak down test I have ever seen......Roy is talking about fan clutch, not if a fan is there.
