4-4. Adding Coolant To Radiator
ST-801 939-C / Ref. ST-187 602-A
Y Stop engine and let cool.
.
Check coolant level according
to Section 4-3 before starting
this procedure.
If coolant level is below bottom of
radiator filler neck, add coolant as
follows:
1 Thermostat Housing Plug
Remove thermostat housing plug.
Add coolant to radiator until coolant
is at bottom of filler neck and cool-
ant trickles out of thermostat hous-
ing plug hole. This ensures all air is
purged from the system.
Reinstall plug and radiator cap.
Check coolant level in recovery
tank (see Section 4-3).
Engine coolant is a mixture of water
and ethylene glycol base anti-
freeze. A solution of 50% antifreeze
and 50% water must be used in this
engine. Do not use 100% antifreeze
or severe damage will occur.
