I'm draggin up this slightly aged thread as I am currently working on getting my Heater installed in CHUG. I find it interesting that there is much discussion of up and down here. My heater the core lays flat with no up or down. It being an after market heater from Summit Racing. My plan is to run the hose from the fitting on the head to the Water control valve I have on the heater and then the return to the Water pump.

So a very flat circuit if you will.

Oh.....I had an existing hole already in the firewall that was in the same upper location as in that pic of the TB 9-2855-37. Just a hair below the battery box. I just ovaled it out and made a grommet out of some split windshield wiper tubing then ran both hoses thru it. I figured the hole was there, why not.

Took some temp readings.  Its a bit cooler driving all things considered but very bearable inside.  I could seal the windshield vent cover, it does produce a considerable draft.

Outside temp.


In the cab.


Right out of the heater register.

No problem there. I'm about full myself. Anyhoo, I put the head port to the bottom tube per the tech bulletin. We'll do a thermo test in them Black Hills to see if there is any difference. I'd bet you there will be absolutely 0 difference. I'm working n getting my pics together. I will post them up here and over on the WMJ page.

Sheesh! My own pics prove (once again) that I'm full of "it". I did follow the arrows so my inlet is the top tube. Opposite the TM. I'll defend myself by saying the install was over a yr ago and I'm now feeble of mind.Ermm

  Are the two pipes on the core the same size? On GM cars, the heater inlet hose from the intake manifold was 5/8", while the return to the water pump (later on, to the radiator) was 3/4". Why, what difference did it make? I have no idea, that's just the way it was.Confused  BW

I think a lot of heater cores flow from the bottom to the top to help eliminate the possibility of air bubbles in the heater core. I think either way should provide adequate heat. Many modern cores have inlet and outlet on same end of core and have a tendency to plug up and cause poor heating. Common problem with Dodge pickups.
