In reply to # 3847737 by Declan Burns Thierry,
Yes, there is not much room on the TF.
The restrictor reduces the partial flow through the bypass.

Declan

It is essential to put this restrictor?
I do not understand its usefulness.
Declan says it's to force the flow into the derivation?

Its not essential, but its desirable. As I understand it, with a modern thermostat, when you start the engine and its warming up, the free flow of water through the bypass will delay the warm-up time (not ideal). This was not the case with the original style thermostat that in the closed position partially blocked the entrance to the bypass. The change in the design of the thermostat to the modern type has made it desirable to introduce a restriction in the bypass entry.
Having said all of the above, its not something that I have done myself. In fact I may never do it as I managed to buy a new but old stock original thermostat.

My TF 1500 has no added restriction in the flow and my heater gets very hot, but seems like the 1250 engines benefit from a restrictor and also where the hot water is pulled from. confused smiley

So, should I know if my thermostat is modern or not?
Okay, so I can do the editing without this restrictor.
And later if necessary, I can always add it.
Thank you David,

Thank you Paul, I'll see the editing.
Sincerely, Thierry de l'Ardèche

Decided to check the temperature rating on my thermostat and found it to be 160F so just ordered a 180 from Abingdon Spares. Took a 170 mile ride with the club last Saturday and the engine temp stayed at about 70C (outside temp around 45F) and the heater only got "luke warm". Should have checked this a long time ago!! Will report back after install of the new thermostat.

I'm going to mount this elbow that we find both for the MGBs and the MGAs
I'll just have to shorten my pipe.
Declan, is the valve of T7Design perfectly waterproof? Can I use it as a closing valve?

Thierry,
The T7 design valve and most of their heater accessories are actually "Made in France" by Siroco.

You have to be careful in push and pull to open as it can be confusing. The bracket is mirrored depending on how you order it. I don't really like the bracket as it looks too modern. The valve itself is really nice and some of the lads on the Morris Minor have installed it with great success. No leakage problems so far. You can move the lever with your little finger.
The valve as shown is a "push to open" version and is closed in the photo above. I would have preferred the "pull to open" with the bracket on the other side.
I have made a CAD drawing as I am considering making heater installation kits.
Regards
Declan

Hi Declan,
Great to have found the company in France. Do you know if they sell to the individual?
I agree with you, the support is too modern. Maybe just with an L-shaped plate and a piece of brass pipe receiving the sheath, I'll think about it.
It's not stupid to make a kit, it should have some success.

Thierry,
I don't know if they sell to the public or if it is trade only. Give them a phone call and the should be able to tell you. Maybe they have an outlet or a dealer near you and it might be cheaper than buying it from T7 design. The postage will certainly be cheaper.
Regards
Declan

Very good idea

Not trying to be critical of new ideas, but why go to all the trouble to hook up a cable operated valve when you open the heater valve,(s) in the fall and close them in the spring? Just curious. PJ

Paul,
Just to have it adjustable as were many cars of the same period.

Hi Declan,
I just found this
It is not very big, the valves are small and if necessary, it is always possible to cut in the center to insert the restrictor and resouder.
When do you think ?
Sincerely, Thierry de l'Ardèche
