Radiator Supply Tank without heater
How would one route the plumbing if no heater was connected?
Let's get the semantics straight - the overflow nipple is welded to the filler neck just below the cap, and has a thinwall hose (no clamp) that just hangs straight down next to the frame. It only contains fluid when the system pressure in the tank overcomes the spring in the cap and "burps" coolant out of the overflow.
The other hose is the "balance hose", which is always under pressure and connects from the top of the tank (below the filler neck) to the top of the radiator, with a clamp at each end.
The supply elbow at the bottom of the tank (which was swaged to the tank on early 63's and later welded in place) connects the tank to the 3/4" heater hose that runs from the heater core outlet to the water pump inlet.

In looking at the cooling system, the high point is over on the driver's side, rad return to pump suction.
How on earth are these systems filled? The radiator cap at the "Radiator supply tank"?
How is the air removed? (Seems it would be trapped in the rad.)
Sorry for all the questions, just trying to undersatnd and want to protect the new engine investment.

I understand what you propose, but what exactly is the idea of the tank? Why does it want to be connected to the water pump?

think of it acting like the coolant recovery tanks on new cars. same principal

as i see it, the major purpose of the tank is to allow the radiator to be completely full of water; that is the purpose of the small hose that runs between the top of the expansion tank and the top of the radiator. that hose circulates water and scavenges air in the top of the radiator back to the expansion tank where it can be contained or expelled out the overflow hose.

Two tubes only.
If the water pump outlet was connected to the "Supply Tank" lower 3/4" connection, plus the 3/8" connetion at the top of the tank to the top of the radiator, that would seem to satisfy the need to allow water in tank bottom, air escape out the neck, correct?

the C1 goes into the top of the water pump but the heater hose fitting into the water pump will work as well (don't connect it to the intake manifold fitting

When "heater-delete" was ordered from the factory (RPO C48), the 5/8" hose from the intake manifold to the lower heater core nipple was deleted and a plug was installed in the intake instead of a heater hose fitting, and the 3/4" hose from the "tee" below the expansion tank to the upper heater core nipple was deleted, and a rubber cap and clamp was installed on the back end of the "tee". Obviously, there was no heater core. This left only the 3/4" hose from the "tee" to the water pump inlet so the tank remained in the coolant circulation system. Shown in the Assembly Manual in section C48.

Heater Delete
OK, we are good.
Actually the car has a heater but it is not checked out so in the interum, we will run without heater core connected.
John Z, we connected it as "heater delete" car as you describe!
(The white on the inner fenders is light from the window.)
We need a couple loops for the fender to hold the 3/8" line up.
What are the lower two holes for?
