Hi Hans,

The final tank is yours then. I will send you a PM  to arrange payment.

I've had my tank installed now for a few weeks and it's looking and working great. Here's a photo of the completed installation. Note that the overflow hose is not fitted: The new tank has a larger diameter outlet and the tank is sitting a few mm higher than the original. This meant that the rubber hose which I tried to fit conflicted with the chassis and prevented correct fitting of the tank. I'm going to fit a clear 10 mm pvc hose which compresses more easily.

Thanks to Graham for having these beautiful tanks made for us!

I am just back on holiday from my work abroad, and have opened the packet with the expantion tank. The tank looks great.
Thanks Graham.

That is funny, I am just busy to find a replacement for it and you come up with the same thing.
I have a topic about it on the Belgium forum but can't link the members section.
[IMG]Renault couldn't help me

I have just gone through this topic...
I am looking for new cooling hoses for the car and I was a bit confused, because I have only three connections on it.
Now I realised that I do not have the original expansion tank. I have the same as Oetker mentioned...
Could you share the experiences about it? Any weak points?

Sorry I could not read your writing on the photo. The top connection goes to the thermostat the bottom to the motor and what is the center connection for?
Could you send some photos of the hoses just to see how you solved them?
Many thanks.

[Oetker]

There is no center connection.
The bottom has 2 in/outlets.
One of the bottom inlets goes to the front (Radiator) It a small tube so you need a reducer.

This setup is running OK without problems so far.
I still have the experimental set-up in the car and drove the car in all circumstances for some time now.

There is one disadvantage.
The tanks holds 1 liter less cooling fluid.
The original holds 2.5 liter and this one 1.6 liter.
No problems so far.

Sorry, I was not correct. I meant center connection refer to this picture, see below.
So it must be OK, thanks.
Only one thing I have to keep in my mind, as I read in the topic, it is adviced not to fill it up to the MAX...

[Oetker]

You need to keep 0.6 liter space for expansion.
Wich is a small bit above half full.

See the movie I provided.
Around the black stripe is ok.
