Removing expansion tank

I just removed my expansion tank bcs it exploded a few days ago. I was wondering if anyone else had such a big problem to get it out? :'D. I tried for about an half our and then ended up getting it loose by pressing it up with a jack. Was really suprised when I saw how bad the plastic had went after almost 20 years :'D

Yup, they fuse together sometimes. I gave up and cut one OE hose end off Jenn's car last summer.
And yet, sometimes, they pop apart at the most inappropriate times.

If you want to see something really disturbing, replace the 2 pipes under the intake manifold.
They 'rot', for lack of a better word, where they go into the head/front cover...

It was pretty easy, make sure you remove the pin at the bottom pipe (although it sometimes does get stuck)

Yes the tanks can be really hard to take off and put on. As I recall I used a floor jack pushing up on a short length of 2x4 on the bottom edge of the tank. I was expecting the plastic the tank sits on to break, but guess it's pretty tough.

I recommend you replace the expansion tank mounting bracket.

Put the cap pack on the et and use a claw hammer and pull that sucker off.
