1985 PT-40 Radiator Question - sfedeli3 - 01-01-2008 13:18
The '85 PT40 with the 6V92 does not have a sight glass. You just have
to keep feeding her 'til she pukes it back out. Usually after the
system is opened up for repairs or hose work, you can fill it up to
the rim and continue to add another gallon or so over the next few
days as the air works out of the system. The 8V92 option in 1986
required a larger engine compartment with a higher ceiling clearance.
The overflow tank was kept at the same height, however, and equipped
with the sight glass.

My 85 pt 36 has a sight glass. Mine was built in Sept.
