Hi Ken,

You're dead right about long term, solid particulate build-up, especially
from the use of regular coolant. However what about the regular changing of
Phosphate-free coolant? Pulling the radiator is not something the regular
Vanagon owner can do as maintenance every two years. Do we have a procedure
for the "typical" Vanagon owner to change just the liquid content on the
Vanagon cooling system? For example fasteners can easilsy seize & break when
removing the push rod tube shields to access the cylinder block drain plugs.
Also if the radiator requires a simple draining, the spare tire & s/t
carrier must be removed to access the lower radiator hoses. How do we advise
the Vanagon group to flush the system??????????????????

Regards,       John
