Hi guys. I fitted mine this afternoon but it seems that the hot water isnt getting through as the part is warm to touch but the pipes the other side aren’t. Almost like there’s an air lock. Any ideas?

My IRB heater control valve arrived last week. Sadly I haven’t had a chance to fit but it truly is a thing of beauty. It deserves to be hung in the Louvre not hidden under my bonnet!
Cheers Ian.


Agree far too beautiful to fit Laughing
However mine is in place and working beautifully, thank you Ian 'Porny' Bow down


So do you have better control of the heat level via the control on the dash. Or is it like the Original LR one , i.e more or less on full heat or no heat with nothing much in between.

Sorted it. I hadn’t fixed the cable in place. Ha

Hey! Jus wanted to credit @newhue for the great idea. I have 110 Puma and I was on my 3rd Heater valve and I've had enough.

Googled and found this thread and tried it out. I can confirm that this heater valvel works, the cabling I still have to work on but the interim solution works (in reverse order).

Just tested this setup for 50kms, will try to update longevity of this setup.

For anyone interested, here's some links from the items I used.

Heater valve - https://www.ebay.com.au/itm/253917762669

I've puchased OEM like valves, and here's the link to that valve - https://www.ebay.com.au/itm/402906245688


Hit me up if there's any questions.

Dear materoforion,
It is my first time in the group after not solving the heater valve problem.
how is your heater valve going so far?
Could you make a video of your modification?
The Intergrated 316 valve is stanning but far too expensive and not in stock yet
Thank you

There are two issues with the stock heater valve. They can develop leaks and they don't fully seal the passages either when fully open and/or fully closed. Leaks are an obvious issue. Not fully closing is only apparent in either very warm or very cold weather.

I have bought aftermarket valves, genuine valves and genuine valves from FIAT and others. The aftermarket valves are the worst but none of them actually seal completely.

I have also purchased the AC heater valve pictured above. It is originally off a Ford. I have bought both aftermarket and OEM. They also don't completely seal at either extreme.

Does it matter? At -30 or +30 it sure as %$# does.

What I'm experimenting with right now is using a brass, 4-way, L-gate, ball valve. They seal so well you can apply a strong vacuum and there are still no leaks. The big plus is that the valves are cheap. I bought two for $40/£20 off amazon.

It is all unalloyed joy? Of course not. The secure seal also means that the lever is stiff to move so you can't use the stock, plastic control. I'm fitting a vernier bowden cable from an aircraft supplier. I'll post photos as I go along...

I finished the valve and have it installed without the cable. Works good. This is a valve with 5/8" fittings. I have ordered one with 3/4" fittings as I think that will fit the hoses better. No leaks, mind, just want it to be fit and forget with the stock clamps. I had to fit adjustable clamps to two of the fittings.

I think some London black cabs use a brass hcv. WARNING.
