Technical 1947 Fleetline Heater

I have a 47 Fleetline that has the round Harrison heater, the core is cracked and all the ones i look up are for earlier years or say they only fit trucks of my year. I would just hate to spend the money for a new heater core that does not fit. Anyone have any experience with this?

 

Could you provide a picture?

 

Take it to a local radiator repair shop. They can replace the core

 

Not if it has a round core. They are made of unobtanium.

But repairable.

 

I have a slightly older round Harrison heater but it has a square core inside that is fitted to a round mounting plate. Note the corners of the tanks are rounded off.

 

Put a rubber plug on one connection. Make a test plug out of heater hose and a fitting for the other connection and pressurized it to about 10 psi and test for leaks. Solder the leaks and you should be good.

Old thread, might still be something helpfully.
