I've had to replace two expansion tanks at my
Indy for the past year and a half. Is this normal or am i getting really crappy parts? I think they are from an outfit called euro spare. Any advice would be greatly appreciated.

 

i had one of those POS, I went with a good used one eventually.

 

I think it may be luck of the draw on the el cheapo. I'm a gamblin man. so far, uro part, has been a win for me.
out of curiosity, where/how are they failing? seam? cap? connections?

 

Hairline crack on the bottom of the tank . Ver very small right now. How much time do I have?
How many have you replaced and how much were they? Thanks again.

 

oem= $100 plus
el cheapo= $35-$40
used oem= same as el cheapo

you just need to keep a constant eye on the level and carry some a freeze.
I tend to go ghetto fab on such issues. so I would try a repair while waiting on replacement. (maybe flex seal or epoxy)
I have only had one fail...well the cap failed and i screwed up the tank while removing a stuck half of the cap

 

Going on a four day road trip so I think I should get it fixed
