Why is my Polaris snowmobile overheating at idle?
I had this issue with a polaris 700, the nut that held the water pump impeller on was loose and eventually fell off (that way from the factory). It would run great at idle, NO air in system, and you could feel the heat going to the back, but once you opened it up, it would overheat big time.
What are the new Polaris snowmobiles for 2022?
For 2022, we are excited to announce the Starfire Series. Built in the spirit of the original 1976 Starfire sled, the new Starfire Series represents the ultra-premium, high performance lineup of Polaris Snowmobiles. It’s our most exclusive snowmobile models, available only during SnowCheck.
Why are the exchangers on my snowmobile getting hot?
When the machine is warming-up, the exchangers are getting hot. When I put around, the exchangers remain hot. When I go all out (for several minutes), temperature gauge rises, motor starts to sputter, then the computer shuts it down. Open the hood and the engine compartment is very, very hot.
Why is the water pump on my snowmobile overheating?
Reach out back and touch the exchangers, and they are cold. Water pump belt has 1500 miles on it. Local mechanic is saying that I may have a pressure leak at the head gasket, dumping pressure into the cooling system. Pressure gets so high, the water pump can no longer circulate the coolant.
How can I tell if my Polaris snowmobile is overheating?
Verify that the coolant system will hold at least 12 psi of pressure. If the coolant surge bottle is not distorted, and the sealing surface looks fine, pressure test the coolant system. If the cap cannot hold at least 12 psi of pressure, the system will overheat very quickly.
What kind of cooling system does a Polaris snowmobile use?
10, No. 8 August, 2002 Much has been learned about the cooling system of the 2002 models that utilize the “smallblock” 500/600 VES engine. Polaris would like to thank the many dealers who have assisted us this past season in identifying solutions to these cool- ing issues.
What causes a snowmobile motor to overheat?
Thermostat is good, even removed to ensure coolant flow. At lower RPM, I have no problems. However, when I get it continually high-up the RPM range and keep it there, the motor starts overheating, eventually shutting itself down. My biggest concern is that the heat exchangers are cold.
How do you test the pressure on a Polaris snowmobile?
1. With the pressure cap firmly in place, remove the over flow tube (1/4” O.D.) from the neck of the coolant bottle and insert the Mighty Vac t hose in its place. 2. Set the Mighty Vac t to apply pressure with the selector lever, and pump the gauge to the specified lbs. for the pressure cap you are testing.
