Basically there are three thermostats in use for our various four and six cylinder
enaines. The thermostat which is used in the Four-107 may not be used anywhere else.
The thermostat used in the Four-60, Four-91, and Four-154 is interchangeable across
that range.
The thermostat used in the Four-230 and the Six-346, both VD and 98 series, is
different from the thermostat above in that it has a movable bottom part which seals
aqainst the lower thermostat housing. Therefore, it is not interchangeable.
A list of correct part numbers follows:
Enaine model's
Four-107
Four-60,-91,-154
Four-230, Six-345
