heater hose locations

I installed an AC system into my nonAC truck, and I'm not sure which hose goes to high side of pump, and which goes to block. Coming out of the heater core, they are situated left and right. On my 351C, I have an outlet on my pump, and one coming out of the block by the dipstick. Anyone know the proper termination of the hoses so I dont cross them?

It doesn't really matter. Coolant just flows through the heater core, and it'll work fine either way.

OK, good, that kinda makes sense. I thought there might have been an issue as far as some sort of "check valve" or sompin like that.
thanks

I agree, but the factory always hooked the water pump to the higher one.

The vacuum operated valve is directional. I beleive water is pulled out of the block, through the core and into the water pump fitting.

All,
What kind of a pump is thw ater pump? Is it centrifugal? It must be? That means, the pump pumps through the heater core. You should always pump the bottom of the coil when opportunity allows. This allows air to rise and escape the coil. it may also stir up the crud and pump it back to the motor, thereby preventing the core from clogging. I know, that last statement is a stretch.
Consider it,
KingFisher
