which hose is which

[Lone Watie]

How can I tell which of my heater hoses is the inlet and outlet? And I use the inlet hose for flushing, is this correct?

I know there's an easy way, but can't find it anywhere. Thanks.

I see the two hoses, one goes to the water pump, the other comes out of the block and goes directly into the heater core. I'm guessing the one from the block to the core is the inlet. Is this correct?

I always flush both out to back flush the heater core. Don't know if its right but it has worked fine for me. Don't use alot of pressure, just the hose with no pressure head.

Do you disconnect both hoses to accomplish that? I understand, thinking that you don't want to push a bunch of muck into the block or the water pump.

I disconnect both and flush both ways letting the dirt wash down to the ground. I use a tapered hose fitting or anything I can push into the heater hoses.
