Closed to Open cooling system overflow leaking
Ok on my 90 4.0 I converted it to an open style using a filler neck and 1 qt overflow bottle which I was told is plenty big. I guess the bottle is just defective but I wanted to ensure I did not do something wrong or choose a wrong bottle.
The overflow bottle is leaking like crazy, steam will come from the top and bracket area and this morning it was pouring coolant out of the ball valve at the bottom even though it's closed.
This is the one I went with:

The radiator cap I chose is a Moroso 12-16lbs cap.
Should I choose a different overflow bottle? Need to fix this ASAP.

sounds like you still have air trapped inside your cooling system that is causing it to boil. did you do a vaccum pull down on the system when you filled with coolant?

I just ordered one for a later XJ and will try to mount it in the same spot.
I did not do a vacuum pull, never heard of that. I've always just ran open systems with the cap off to allow it to burp for a while.

Drove around yesterday with the new bottle and it's working great. It also holds a lot more coolant than it did with the small bottle.
