Hi ..
buy the welded aluminum tank Van Cafe sells.
About $ 200.
I just put one on a Diesel vanagon..works nicely.
the cap took a lot ( too much really ) of downward hand pressure to get it
to go on...I had to tweak on the ears of the pressure cap. I told VC about
it.
physical repairs to the old bottle are temporary at best, in my experience.
send a picture of your air filter element and we can tell you if it's too
soaked in a-frz .
like..how would we know ?
you're the person by the van.
and no paper air filter element would be very useable if it got well-soaked
in any liquid.
if you fill it, run it, fill it some more..
and keep doing that a while, including running the front heater ...
Then just let it sit for a good cool-down period ..
like say 2 to 4 hours...
you'll see the level in the pressure bottle has dropped from where it was.
Top it up ..
run it through another well warmed up cycle..
then let it sit, like overnight .
then top up that air space.
do that 3 or 4 times ...top up he air space at the top of the pressure
bottle , after a full cool-down ..and it will be plenty bled , assuming
everything in your cooling system is basically working like it should.
