Custom Radiator with an lines, heater core lines?

[Drifte]

Working on a car here, that has a radiator with an fittings welded on, one runs from the water pump to the bottom of the radiator. Thus, eliminating the water pipe. This also means the heater core hook up is gone for one side.

So my question is, what direction does the coolant flow? Is the water pump sucking coolant from the radiator, or pushing it into the radiator?

Picture of the radiator in and out fittings:

There is a blue fitting plugging a port on the radiator, depending on flow direction, we may tap into that for the heater core.

[edit] looks like the waterpump pushes coolant into the block.

Does anyone know if it will flow right coming from the blue fitting on the radiator going to the heater core? The water pipe was replaced with braided hose.

The water pump pushes water from the block to the rad, if that helps at all. Not sure about plumbing in the heater core though.

heater core they go into the thermost housing.

Ok, the Heater core has hoses running from the Thermostat housing. One Hose will run to the Thermostat housing to the radiator, and one hose will run from the water pump to the radiator. If one is hooked up to the water pump then it is not eliminated. or else there would be no way to cool the motor. If you don't have 2 hoses coming for the housing to the firewall then your heater core isn't hooked up. What's weird is that the radiator hoses are on one side of it instead of 1 on each side. A better picture would be better. Also the blue plug should be were and tranny lines would go to, unless it is a manual or has a aftermarket cooler. That would explain why that plug is there.

Colton, the -6an bung on the radiator is intended for a coolant return line. Since he's running the oil only 6262 I capped it off. When I sold him the radiator I told him it was more a race only part and that the heater core hoses had to be eliminated and he said he was okay with that. I'm not sure of any way to re-plumb the heater core hoses back into the system without removing the -16 lines and modifying the water pump. If you and Ryan have and other issues don't hesitate to give me a call, he's got my number.

Only thing we can think of, is a -16 fitting in the lower rad hose between the water pump and rad. It won't be cheap, but the last minute change to needing the car now instead of in 4 months can't be helped.

Otherwise it would be new waterpump, find a stock radiator, and an oem waterpipe. Not really a cheap solution either, if it were me id find a winter beater with heat!

ok, So do you know if I would be able to use that -6 plug on the radiator to run up to the heater core? Will it matter which side it plugs into ( I would think so)?
