Having trouble with the New Heater Control Valve!

Alan, take the valve off and if you can blow through it easily, then it is not your problem. Then the problem lies in the plumbing. The hose should come directly from the top of the water manifold to the valve, then to the heater core and from there back to the lower water manifold, I think. I can't think of any reason why the heater valve shouldn't open, but if you work the part that the cable moves with the valve out of the car, it should be plainly visible if it is opening or not.

Heater cores also have a nasty habit of becoming clogged... Especially with low ussage.

Y'know, I noticed a decrease in heat when I replaced the heater core on my '55. The original was what I would call a "cellular" type core and the replacement is a tube and fin type. I als oreplaced the valve at the same time as both were leaking. Before it put off incredible amounts of heat, now, not so much. But I will probably not worry about it untl absolutely everything else on the car is fixed...

Grumpy AuC> Heater cores also have a nasty habit of becoming clogged... Especially

Nate did you replace the heater control valve (HCV) with the new valve that S- I offers? I purchased the $86 USD control valve from SI. The new HCV does not have the temp sensor that the old one has.

FYI my heater core is original and in fantastic shape, so I know it is not that.

Plumbing wise: The top of the waterpump manifold is going to the Y section of the (HCV). The straight lead from the HCV is going the the bottom of the heater core. From the top of the heater core to the bottom of the water pump manifold.

I took the Hawk out last night Downtown Toronto anyway (it was a mild night

It would have be better for my date if we had some HEAT any other suggestions?

Nope, I bought a rebuilt one from Jon Myer. My valve is different from yours anyway as I have an under seat heater.

Thanks Tim,

I will check for the blow through, There is a good possibility that the car does have a 160 degree thermostat s>Alan, it sounds like the plumbing is in order and if the HCV is opening

I never used anything hotter than a 160° thermostat when I lived in New England and never suffered for the lack of heat. Even my T-cab with a three row radiator provides ample heat even though the temp indicator hardly budges.
