I have a 69 big block no air with a exspansion tank.
The tank has 2 large heater ports on the botoom, I think there 3/4 inch.
The heater core has a 5/8 port and a 3/4 port.
How are these hoses routed.
Thanks:
Tom
Hi Tom,
The 3/4" hose runs from the water pump nipple to the tank, and then on to the heater core pipe.
The 5/8" hose runs from the intake manifold nipple right to the heater core pipe.
Regards,
Alan
