Subject: too much bleeding on this list
Content-Type: text/plain; charset=us-ascii
Ben,
I think there is too much made of bleeding the
vanagon. The coolant ring was sure an improvement
but more important were changes in the waterpump and
thermostat. The only thing to be really concerned
about when doing the bleed is that no big air pockets
get trapped in the waterpump resulting in no coolant
movement and you open up a bleeder screw somewhere.
Jacking the van up or down and doing all this hokey
pokey is a bunch of crap and I think the vanagon list
has harmed many new comers to vanagons by putting the
fear of bleeding on too high of a plane.
I think part of the problem is that oftem people
are trying to bleed a vanagon with a bad head gasket.
If you have a failing head gasket in the early
stages, no amount of bleeding is going to fix it and
you are not responsible for the head gasket failing
when it does fail after your many attempts to bleed
this problem away. The most important thing to
consider when bleeding is that after you think you are
done you may want to check the coolant resevoir after
doing some short trips that heats up the entire
coolant system.
Some good hill climbing will aid in the bleed. Never
overlook the value of LOOKING AT THE RESEVOIR as well
as CHECKING THE OIL. many happy miles, gary

Subject: Re: 1.9L Coolant Bleeding
Well, did you raise the front (and rear!), i won't
elaborate on that
subject
to much but to make a long story short:
Run the van, raise the front, bleed the van!!! (and
rear would help
also on
the 1.9L)
I just did my 84 and it took 4 bleeding before the
temp was back to
normal,
i also raised the back the last time.
My conclusion is that there is a big difference
(bleeding system)
between
the 1.9L and 2.1. (1.9 is missing the self bleeding
ring in the
back!!!big
difference!

The 1.9L will never get rid of those remaining bubble,
the 2.1L will!!!
It's a pain in the but!!!
Cheers, Ben

>>>>>>>I have just replaced a heater hose. I have read
the threads and
Bentley about bleeding.
I am not sure about how much bleeding to do front and
rear.
The front seems to be done when the coolant pours out,
right?
I still seem to have a lot of bubbles, small, as I run
the system open
and
closed.
I have a blinking red light until hot and suspect air
in the system.
What next<<<<<<<<<
