Expansion Tank Flow Query

[ukkid35]

I have just had a fairly new expansion tank fail at the seam

I have also noticed since it's still very clear that there is a significant flow of coolant from one or both of the coolant rail hoses in to the expansion tank when the engine is revved - is that normal?

I'm wondering whether this is related to the failure

Thanks, that is very reassuring indeed

It failed on the seam at the side that goes along the wing

Full disclosure: I did remove the triangle at the end of the wing side seam nearest the front of the car, this was probably a mistake

I was intending to hold on to it in order to get a £16 refund from EuroCarParts, but I'm not going to bother now since I've just realised that the modification will have nullified the warranty

Anyway trying to claim £16 back for something that has caused consequential losses over 100 times that seems petty to say the least

I will take some photos though

On the plus side, I don't think I have head gasket failure again which was my initial fear

Split at the seam.

Thanks, sounds like there was a bad batch, I've decided to carry a spare in the boot

after John's comments, I checked the Wiper Panel fitment and the cap they supplied won't fit

There may be room to move the bracket nearer the bulkhead
