[75gmck25]

I'm trying to use the complete serpentine belt system from a '99 350 engine on my '75 vintage 350 engine. I am using an Edelbrock Performer manifold and carburetor, and I have standard (not Vortec) heads on my 350. I have everything figured out except the two small hoses on the '99 water pump.

My '75 has one heater hose connected to the intake manifold and the other connected to a small hose connector on the radiator. There are no small hoses connected to the water pump.

The '99 water pump has two small hose fittings on top. It looks like one was connected to the intake manifold with a short hose, and the the other has a connecting hose (metal/rubber combination) that heads in the direction of the heater hose. I also have a section of heater hose that has a vacuum-controlled valve in it.

If I want the bypass system to work properly when the thermostat is closed/open, where do I connect the small hoses on the water pump? My first guess is the one on the passenger side goes to the intake manifold and the other one goes to the heater hose. However, I don't have a '96-99 to take a look at and verify the connections.

Thanks,

Bruce
