Subject: [FlyRotary] Water Return in Radiator

I need to add some water returns to my cooling system = and want=20 to make sure this will work before drilling holes in my Griffin=20 radiator.  I need to return water from my heater core = and Fluidyne=20 heat exchanger to the suction side of the water pump.  My = plan is to=20 drill a couple of holes in the end of my radiator and weld on a couple = of AN /=20 NPT fittings to attach the hoses to.

Doug,
I took a look at the = Mazda=20 radiator to confirm my recollection of the car version to the heater=20 return.  It is Y connected to the radiator and it looks to me as = if it is=20 connected to the line that comes from the water pump. This would be a = high=20 pressure area except the way the Y is used, it causes the flow from = the heater=20 to pass thru the radiator for additional cooling before returning to = the=20 engine.  I was thinking of returning mine back to the water pump=20 directly, no additional radiator cool, but use a throttling valve to = adjust=20 flow of cut it off completely.
