drain plug at the rear of ride plate.
1. Cooling drain plug
Use an appropriate container to collect coolant.

COOLANT REPLACEMENT
Recommended Coolant
Use a blend of 50% antifreeze with 50% water.
Premixed antifreeze/water is available (P/N 293
600 038).
To prevent antifreeze deterioration, always use
the same brand. Never mix different brands un-
less cooling system is completely flushed and re-
filled.
Do not reinstall pressure cap.
CAUTION: To prevent rust formation or freez-
ing condition in cold areas, always replenish
the system with 50% antifreeze and 50% water.
Pure antifreeze will freeze at a higher tempera-
ture than the optimal water/antifreeze mix. Al-
ways use ethylene glycol antifreeze containing
corrosion inhibitors specifically recommended
for aluminum engines.
