Heater Hose Connection

rlee63a4Member

What heater hose connection (water pump or block) from the engine end should be the input into the heater control valve?

It doesnt technically matter, but in order to reduce pressure on the heater core at high rpm, you should hook the block fitting to the control valve and the water pump fitting to the heater core.

Didn't figure it mattered much, but that's how I would have hooked it up. Just wanted someone to confirm. Thanks.
