Volks- Since Karl Mullendore isn't available, I was forced to have my
non-vanagon mechanic replace some coolant hoses.   I asked them to follow the Bentley
when bleeding air, but...

How harmful is air in the left/pressure/expansion tank down to the right-side
tube ?   I reckon the system self-bleeds, but despite constant monitoring of
both tanks (non-pressurized/license/overflow coolant at max), NO low-level
light or hot engine temp. on 40 min. drives, I'm paranoid!

Good/bad idea to release some air by twisting blue expansion cap when engine
is warm?

I'm sure it'd be better to re-bleed, but if it ain't broke....
