Re: Heater core replacement

An interesting idea but I would chase down some actual dimensions. Amazon specs are probably the shipping box but if anywhere close to actual core or assy size I doubt it will fit in the heater box. The large space at sides where the tubes reverse direction would also need to be covered to prevent air bypassing the core.

Maybe not a concern but a heater core flow is thru small passages so water is moving fairly slow and can transfer max heat but the tubing on the cooler looks fairly large and is short. I would wonder if the flow would be so fast thru the tubing it would almost be like a bypass or shunt effect similar to just connecting ports together with a length of hose. Like the hose shunt issue, that could lead to a substantial portion of coolant never seeing the radiator and perpetually heating which maybe in a PA winter would be a good thing but still.
