Help with Heater Hose Routing

[TLeBlanc]

I want to disconnect the heater on my 64 as it is something we don't need much (if at all) here in Houston Texas.... kinda like having an air conditioner at the North Pole !!

In doing this can I just route the 5/8 heater hose coming off the intake manifold to the remote surge tank ?

Yup, you can bypass the heater core, no problem. HOWEVER, you have to keep the 3/4" hose from the tee at the expansion tank that runs to the fitting on the water pump. Just put a 3/4" rubber bypass cap on the firewall end of the tee, and you can remove the 5/8" hose entirely that runs from the intake manifold fitting to the bottom heater core nipple (put a 5/8" rubber bypass cap on the manifold fitting); this is exactly the way the factory C48 (heater delete) cars were done. If you remove the hoses at the heater core nipples, be VERY careful - you can crack the solder joints between the nipple pipes and the heater core if you reef back and forth on the hoses to get them off - the only way to remove them without damaging the heater core is to slice them lengthwise with a razor blade or box-cutter and carefully peel them off the nipples.

You can accomplish the same result by putting a shutoff valve in the 5/8" hose from the intake fitting to the lower heater core nipple; that will stop circulation of hot coolant through the heater core and will also de-pressurize it.
