And make sure to get the correct yellow o-ring. Standard black ones are
too stiff and will distort the flange. Also, replace the stupid plastic
bleeder screw with the break off head with a steel screw and use some
sealant on the threads. There is no reason to open this screw for
bleeding. The heater circuit moves enough water to the suction side of
the pump to bleed itself no matter what. It is amazing how fast the van
can fill with coolant when that bleeder screw breaks.

I'd try a new shop. I've replaced dozens of these suckers over the
years
and never had a problem with leaking at different pressure levels.
Sounds
like voodoo science...
BTW: When you replace the core, you should also replace the valve &
o-ring.
Cheers,

I have a rear underseat heater on an 85 Westfalia that has made a
complete
fool of me. I have a small leak that arises somewhere in the core or at
the valve and each time I think I have it fixed it comes back to haunt
me. Finally took it to a radiator shop and they recounted their own
problems with them. It seems that each piece of tubing is embedded
discontinuously so that leaks can arise at either lower or higher
pressures where the pipes enter the end manifold and there is nothing
that
can be done about it. I have had that heater in and out 6 times. This
guy
said that he has watched cores that are perfectly sealed at 30 PSI and
leak
like sieves at 15 PSI. It will never do that to me again----I beat it
to
death with a sledge hammer. Please don't let it make the same fool of
you. It used to be that as a young man I had endless patience for such
nonsense, but no more. I find that the sledge comes out more and more
frequently now, may eventually take it to the whole vehicle. I am not
proud of that kind of behavior, but not too ashamed of it either.
