Re: IML: 1964 Heat Control Valve, also check cable & clamps



Hi Rob -

Can't speak for anyone else, but the one in my '60 has lasted 46 years. I'm betting it's a cable adjustment like Paul suggests.
Good Luck -

Hi Paul,

I have the same problem with my 60, I can't complete shut off the heater :) In cold weather this is nice, but now with the temperature rising it is getting pretty hot...
I guess I have to look at valve end then?

Or are the 1960 heater valves prone to failure over the years (internal leak) ?

Thanks,

Robert

Check this thoroughly first. It sounds like you are getting heat and can't turn it off. That is usually a control cable problem, not the valve itself. This is most common on '64 through '66 models at the lever end. and '60 through '66 at the valve end.

The control cable has clamps at each end, and is adjustable. Frequently, the cable slips at one end, or the clamps fall off causing it to have no effect on opening or closing the valve. When it fails, the valve usually leaks, which it may very well do once you get it turned off.

The cable also can break off at one end having the same result. You really can't tell unless you look into it further. I believe that on your car, you can view the operation of the valve by moving the lever if you remove the glove compartment. Then you can shine a light in there and see what the valve does when you move the lever. If the valve doesn't move, it will also allow you to determine of the problem is at the valve end or the lever end. Trouble with my '65 has been at the lever end. That is more difficult to work on since there is more stuff over there, but it can be done, carefully.

If that turns out to be the trouble, you can become creative and replace the spring clip type clamps with something more substantial. I have seen combinations of filed off washers, screws, lock nuts, and lock washers that were very effective. These days, even a strong cable tie might help keep the original style spring clamp firmly in place.
