@Lardog posted:Roland, I removed the heater in the tunnel, I will get the water from one of the tubes where I put the bungs into. NO hot water going through the car. It will come from the front tube going to radiator to the passenger foot well to the heater, see below. I think it should work, might have to install an extra pump. What do you think?
I think you have to provide a 90 degree tube that faces into the pipe going to the water pump to act as an Venturi.. preferably in the return pipe coming from the radiator..(there may be also a pressure difference between inlet and outlet in your advantage caused by the radiator restricting the flow and due to the cooling of the water)
I think Water would just pass by at the holes / turn offs ! Both are in the same tube.. no reason for the water to move into one of the ports…
With the”Venturi “ it should get sucked into the heater core..
I would try to use the natural flow of the water to transport it through the Heater Core..
you still give the engine (and heater core) the water hose treatment.. right…
no reason there wouldn’t be rust and sludge buildup in the water jackets as well!!!
