603 Heater Water Valve

[douglas j]

I think the valve is actually on the drivers side just above the dip and water jet foot switches, which are virtually impossible to operate as they are too hidden away. The valve is not like the smiths unit shown in the photograph and mine to had jammed but with a fair bit of penetrating oil eventually freed up. It also may be worth looking at the slider control on the dash as that is not the best bit of design and is held by a spring clip and does fall off, to see it remove the centre dash section and use a torch.

Purely out of interest if you fold back the vinyl cover at the fire wall what does it cover. On the 411 and 412 there is , on the drivers side , the Smiths fan , in the middle an air distribution box and further over the Smiths Heater box. What does the setup on the 603 look like ?.

I am currently working on my Mk 2 version of intergrated air conditioning in the 411 by replacind the Smiths system with a Vintage Air unit which is both an air conditioner and a heater in the one unit. I had it working for heat (very good result) but I could not ,on my first attemp get enough air flow into the cabin to properly cool the car thus I am redesigning that part of the instalation.

What has been done on the 603 may help with my project.
