My lsx startup is heating up fast, with no return to the radiator. I unpluged the steam vent and started it up and got nothing. Shouldnt water be coming out? New thermastatI'll try next, just seems nothin is turning

 

Make sure your heater hose are free of blockage the water must move thru them first.

Good to know, Thanks Tim!!!

 

I.E. heater valve off?
thanx

 

Pull one heater hose loose from the core and fill the block through it. Then the thermostat will heat up and open. What you are getting is a common problem with LSX engines. No water behind the thermostat at first so it doesn't get hot and open.

 

thats the prob, thanx everyone for your help
