On the early alpine (SI and SII), there were 2 type coolant expansion tanks fitted.
One used a simple cap, and a removable pressure relief. The other used a normal relief cap only.
The one with the simple cap can use a normal pressure relief cap, but has nowhere to relieve the coolant to.
No for the question. Which ones are fitted to which years or models?
Since there is a difference in the diameter of the coolant hoses, which one belongs on a series II, and what inner diameter hoses go along with it?
AND....
Does anybody have a spare tank that doesnt have the added pressure relief valve?
My car has the other one, and its life is about up.
