Engine Cooling System
Coolant Level
Independent suspension model
The recovery bottle, located under the seat, must be maintained between the
minimum and maximum levels indicated on the recovery bottle.
The engine coolant level is controlled or maintained by the recovery system.
The recovery system components are the recovery bottle, radiator filler neck,
radiator pressure cap and connecting hose.
As coolant operating temperature increases, the expanding (heated) excess
coolant is forced out of the radiator past the pressure cap and into the recovery
bottle. As engine coolant temperature decreases, the contracting (cooled)
coolant is drawn back up from the tank past the pressure cap and into the
radiator.
NOTE: Some coolant level drop on new machines is normal as the system is
purging itself of trapped air. Observe coolant levels and maintain as
recommended by adding coolant to the recovery bottle. We recommends the
use of a 50/50 mixture of high quality aluminum compatible anti-freeze coolant
and distilled water.
