I’m in the process of mocking up all of the cooling system components on my hot rod bread truck build and I’m at a point where I’m not sure if my plan will work and I’d like to ask for ideas.
In these stepvans the heater core is much higher than the top of the radiator and there is no place to mount a surge or recovery tank above the heater core. There is a place above the brake booster to mount a blind expansion tank that will be above the heater core . My thoughts are that to fill it I could pull a vacuum on the system at the remote recovery tank and slow fill the system from the radiator drain valve till I see coolant entering the upper expansion tank.
Canton racing claims that we should allow 6% for an expansion space. My thoughts are to build the upper expansion tank large enough so that at temp it would be nearly full and not to the point of pushing coolant to the recovery tank. This design is dumb because if I have to top it up at some point I would have to add to the recovery tank while the system is warm and then let the shrinkage from the cool down cycle pull it up into the expansion tank.
I’m open for any ideas on this as I’m not convinced that what I have drawn will work as planned. TIA
