new coolant expansion tank
Hello,
I just bought at welshent.com a new coolant expansion tank, mine was too much worn out and losing fluid from everywhere.
now I got a question.
The return metal pipe to the upper part of the expansion tank the one close to the cap looks weird to me. The orientation angle is wrong it points inside the edge of the expansion tank. How can I fit the hose in it? that metal pipe is soldered and won't move.
Should I file the edge of the expansion tank in proximity of that metal pipe ?
thank you

well looks like it is manufactured like that all MTC tanks are like this look at the picture:

I think I will use a tool to bend the pipe little bit.

It's intended to supply coolant to an overflow tank located within the wing, front of tyre, and then retrieve the coolant after the engine is shut down. The coolant exchanged occupies about the top inch of the brown tank...if you fill it below that level there is no overflow, and the second tank isn't needed. That's what I did, having fitted the brown tank but not the black overflow tank to my Series 1.
Agreed that letting coolant it hit the flange is a good idea of you don't use the second tank. If you do want to use the factory setup, I believe that sawing off a bit of the pipe would allow access for attaching a hose...there's never any pressure in it, so attachment isn't critical. IMHO.

Correct.
The plastic tank used on the Series III was part of several cooling system changes circa 1983. Plastic tank, different thermostat housing, different fan clutch, etc.
Earlier Series IIIs used the same stuff as Series II cars

Although the brown plastic tank ion my car is gone, the "catch" tank behind the left out board lamp remains. The filler neck on my car, not original, has that pipe. It is connected to the "catch" tank.
My take on these repo tans s that they are flawed. Why is pure speculation.
My solution would be as mentioned, cut it or bend it and hook up the hose.
Letting coolant "blow off" to go to ground is not good. The glycol is poison to many critters, and worse, it is sweet and attracts them
And, of course, chemicals in to the environment.

so I did replace the expansion tank myself. New job for me it took more than 1 hour.
I do not know how much should I tighten the nuts on the expansion tank. I would not want to wreck it. But if I tighten them little bit the edge tends to bend little bit, if I do not tighten them they seems to be too loose. Here is a picture of how they are tight now on the new tank. any hints are welcome. Thank you.
