34studepres Posted August 17, 2018 Share Posted August 17, 2018 Is there an inline water pump you can buy that would go in place of the bottom radiator hose that gives the internal water pump a boost for higher flow? tom griffith lincoln1955@msn.com Link to comment Share on other sites More sharing options...
Ozstatman Posted August 17, 2018 Share Posted August 17, 2018 Would that be a good idea? I'm thinking that the water/coolant in flowing through the radiator must have sufficient time in the core to enable cooling to take place before it returns to the engine. Speeding up the coolant flow may not give it enough time in the core for it to cool sufficientlybefore it returns to the engine. Link to comment Share on other sites More sharing options...
Grimy Posted August 17, 2018 Share Posted August 17, 2018 I'd first check the factory pump, to ensure that the impeller has non-eroded vanes and is firmly attached to the shaft, and that the lower radiator hose (if longer than four inches) is not collapsing at speed/high suction. Is there any foaming at speed or pushing water out the overflow (if so, might indicate that air is being sucked in past the packing)? Link to comment Share on other sites More sharing options...
HH56 Posted August 18, 2018 Share Posted August 18, 2018 There are remote water pumps that could be plumbed in place of the hose but would take some doing as I doubt anything modern will have as large a diameter inlet and outlet as the old radiator hoses being removed. If you need to make a size change you would need to cram any adapters etc in a probably confined space between the radiator outlet and engine inlet and still run hoses to the location of the new pump. A bigger issue is I doubt you would find any pumps for 6v if that is what your car is using. As others have mentioned flow rate thru the radiator is important. I know several have tried removing thermostats in the thinking that the thermostat was restricting flow and they would get better cooling with it removed. As I recall from discussions on other Packard forums that was not the case. Link to comment Share on other sites More sharing options...
