Coolant Draining - Polaris 2007 Two Stroke Service Manual

Coolant Draining

WARNING
Wait until the engine is cool before removing the
pressure cap. Removing the cap while engine is hot
and the coolant is under pressure may cause
serious scalding.
One method of draining coolant from an engine is to use low air
pressure to aid the extraction of coolant.
1. Remove pressure cap.
2. Siphon as much coolant as you can from the coolant bottle
and coolant lines.
3. Remove the top hose from the thermostat and insert it into
an empty container.
4. Apply 3-5 psi of air pressure to the thermostat cover until
no more coolant can come out of the thermostat hose that
you inserted into the container.
NOTE: This will only get the majority of the coolant
out. Some may remain in the system.
