Hi all,

My brand new heater valve started leaking after only a few miles.

Hoping for some guidance I did a search on the forum.  It seems I am not alone......
Nick is particularly vocal - and the solution he posts (as pasted below) looks very similar to what I need.  There is also a picture of my arrangement (with original valve) below.

Where did the valve come from Nick?  ...and has it proven reliable?

Any other suggestions?




My arrangement:

I have the same on the 6 cyl. It's an OE valve from the International Harvester model Scout.

They were very difficult to get hold on, whenI was looking for one. I bought one from Amazon about 10 years ago.

Valve is used on many older US cars. Also a popular mod for TR6s in the US.

Pretty sure that I’ve seen them for sale as upgrades by a UK TR specialist but at a fairly unreasonable price.

However they are not easy to come in Europe even though a valve from the same maker is used in black cabs.

I think I bought mine from Rock Auto. It was cheap. The shipping was not cheap. And then the tax man got me....

IIRC the hose stub is 5/8”(16mm) not 1/2”.

Does work well. I hate the Smiths valve copies. Total crap.

I did the Four Seasons valve on my TR6.  It is a much better part than the original.  Nick is correct, though, the hose barb is for 5/8 ID hose as opposed to the 1/2 ID hose on the TR.  The hose will go on, though.

...and Ed, the yellow machine looks gorgeous from the close up.

Almost too good to run and allow oil leaks and heat to spoil everything!

everything Ed does looks gorgeous - have a look at his blog. WOW!!!
