Water pump/radiator question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi,

I've got a 71 blazer, manual transmission, no A/C. The PO bastardized pretty much everything in the truck, including (I think) the radiator.

Right now the heater core has hose going from the intake, and another from the top of the radiator. The port on the side of the waterpump has been plugged.

Here's my question -- How was this originally plumbed? The waterpump that NAPA lists for this truck has no port on the side of it for the heater core. Also, they show a 71 radiator that doesn't have a port for the heater core either! What's up with this?

Thanks,

Brian
