MAINTENANCE AND LUBRICATION
Coolant Change (Closed Loop System)
Have your authorized Polaris dealer change the coolant
in the closed-loop cooling system every four years.
Coolant Level (Closed Loop System)
We recommend the use of Polaris Premium 50/50
Premix coolant for your watercraft. This coolant
premix provides freeze protection down to --26
°
F
(--32
°
C). The premix is 50% propylene glycol (an
environmentally friendly product) and 50% de-ionized
water. See page 101 for part numbers of Polaris
products.
NOTE:
Never add tap water or lake water to the
cooling system. Minerals cause deposits and
may react adversely with the metals in the
engine and cooling system.
CAUTION
Storing or operating your watercraft with an
improper coolant-to-water ratio can result in
serious damage to the engine. The 50%
propylene glycol and 50% de-ionized water
premixed coolant recommended by Polaris
provides freeze protection only down to --26
°
F
(--32
°
C). If your watercraft is stored or operated
in colder conditions, you must change the
propylene glycol/de-ionized water ratio to provide
adequate protection in those conditions. Always
return the coolant to the 50/50 ratio before
operating in temperatures at or above --26
°
F
(--32
°
C) as the more concentrated coolant may
cause engine damage at normal temperatures.
