1966 Pontiac Star Chief heater core question
 

So I've got my car running decently again however it started puking fluid out of this diaphragm in front of the heater core does anybody know what it's called so I can replace it or does anybody know where I can get one?

Heater control valve.

Can i just bypass the heater core by connecting the water pump and the back of the passenger side head?

Or could i just cap off the water pump and head And delete the hose?

I have used the first option successfully,

You can just replace the valve with a piece of pipe like non ac cars.

Well first up, that's not the heater core, that's the evaporator for the A/C unit. The heater core is INSIDE the car, behind the evaporator box.

And if you just bypass that valve (which you say is leaking), then you will have hot water running through the heater continually. Probably OK in winter, not so good in summer.

Unless you are not bothered by no A/C, I'd either buy a new heater tap which our hosts here sell (as per above), but I do know you can get them from Old Air Products. I bought one from them some years back and it works fine.

Or if you don't want to worry about no heater, just bypass the heater and the heater valve by circuiting the water out of the pump and straight back into the block. You can even just plug each end and have no hoses at all.

Tell us how it works out
