WARNING
Never remove the pressure cap when the engine is warm or hot. If the pressure cap is to be removed, the engine
must be cool. Severe personal injury could result from steam or hot liquid. Use of a non-standard pressure cap
will not allow the recovery system to function properly. If the cap should need replacement, install the correct
Polaris cap with the same pressure rating. Refer to the appropriate parts manual.
NOTE: Always use Polaris premium antifreeze 60/40 premix. Bleed system at specified RPM or air will remain
trapped in system, which may result in overheating.
