I took apart my failing heater unit this weekend, found a spare valve and bolted the whole thing back together (not a 5 minute job!) only to find the spare leaks - badly!

So does anyone have a spare one of these . . .



I only need the valve, not the unit it attaches too, although it would probably be easier.

I hope you can help

not that it helps but I am planning to work on making an alternative to this valve as mine leaks as well.

If your one is going to go to the skip, I could use with one to "experiment" with...

Let me know how you get on - I was thinking of taking this to a plumber and seeing what he thought - assuming he was able to stop laughing that is!

Has anyone got a fooked valve to send over for "experimentation"

I am keen to get this system to work in conjunction with the original Saab heater controls.

I will keep you updated!

Simon,
They're not designed to be taken apart and repaired. If you can't see the leak so you can solder it the alternative is to replace it with the water valve a washing machine connects to. Just get 2 half inch elbows and some short straight copper tube and solder together a U shape. Fit the valve to one end of the U and replace the plastic lever on the valve with a metal one (you've got to make this yourself). Then tie the assembly to the plastic cover from the original thermostat and bolt the wire from the heater control to the end of the lever.

You've got to measure a bit first to get it right. I managed to put the valve upside down but it still works....backwards. The thermostat is redundant but I don't think they ever worked well anyway.

Graham Macdonald in Hereford got mine repaired for about 10, but this was about 4 years ago. I had to send my old valve off but used the car by joining the hoses.
Works great now - no leaks.
Might be worth a phone call.
Steve.

Thanks Steve - I just called him - he still fixes them - to fix and test the complete unit costs 42, which isn't too bad compared to the new ones you can get from Rolf Jensen for 75

My valve is seized solid in the hot position and leaks as well. Does that mean it is beyond repair?

Further to my post in "At Last", my heater valve leaks. Water droplets were emerging from the centre of the rubber grommet and more so from the crimped joints. I have dismantled it. The rubber appears not to be broken though shows wear but may well reseal with aid of sealants. I will certainly give it a try.

Well, put it all back together with silicone sealant. Don't know if it will work, time will tell. No apologies for the state of the work bench and associated areas... a Work in Progress !!

I left it a day and it seems to be holding water. Will get it back in to the car at the weekend and see what it does under pressure.
If it works, I am happy to have a go at yours.
