Hi,

My friend mentioned there is a popular heater hose mod that can be done on GM engines.. He says you can remove a plug from the water pump and put a fitting there and hook a heater hose up to it, removing the heater hose from somewhere else.. Basically hoses are re-routed??
Do any of you guys know how this is done? Its -32 F degrees today and my blazer interior isn't staying warm enough :(

I'm not sure exactly what all that would involve. I do know that you can get different fittings that go on the waterpump outlet to the heater core. The differences would be the size of the inside diameter hole.
