leaking under dash hot water valve to heater box

I had the same problem, and eliminated the valve altogether by installing a remote valve in the engine compartment. There is a potentiometer under the dash that hooks to the control cable. The valve returns water to the block when closed, and loops to the heater when open. You have to extend the wires for the control with some ribbon cable. Found mine on E-bay.

Thanks Dave.
Will look into this as an option.
as the rebuilt ones from vendors are ver expensive for what amounts to a kit.

Chris,

Here's an easy fix posted by larryw:

If you have access to the July 2011 POCA Newsletter, I wrote an article on installing the electronic heater valve that Dave referenced in the post above.

This looks like being the same as the earlier mentioned eBay valve. If you are a bit handy, this should do the trick too

You are right, that is a better value. In my experience, you either want heat, or you don't, so an on / off setting on that valve is all that is needed. The variable setting is not necessary and therefore you don't need the fancy potentiometer offered by the E-bay vendor.

Hi guys and thanks for input.
Having done a little more investigation and deciding I had little to loose. I dissembled the the heater valve. and went to a local seal merchant and he located modern replacement seals for the o ring top cap and cup seal shaft end for $10.00 kiwi. about $7.80 US. I have not replaced the tapered seat seal at this stage as a one off can be manufactured for about $100.00 kiwi $ as was more concerned with the leak into the interior of the car. if I was to have more produced for exmaple 100 would likely cost about $5.00 NZ apiece. So you can see a replacement kit could be produced for very little. add a little labour to bead blast or polish the tap and pressure test. job done.
