Ski Doo 600 ACE ET Cooling System Maintenance

The Ski Doo 600 ACE ET is a popular snowmobile model known for its powerful performance and efficient engine. To ensure optimal operation and prevent overheating issues, proper maintenance of the cooling system is crucial. This article will guide you through the essential steps to take care of your Ski Doo 600 ACE ET's cooling system.

Regular Inspection

Regularly inspecting the cooling system components is essential to ensure they are functioning properly. Start by checking the coolant level in the coolant reservoir. The reservoir is typically located near the engine and has minimum and maximum markings. Ensure the coolant level is within this range.

Inspect the coolant hoses for any signs of cracks, leaks, or wear. Replace any damaged hoses immediately. Additionally, examine the radiator or heat exchanger for any debris or obstructions that may restrict airflow. Clean the cooling system components regularly to maintain optimal functioning.

Coolant Flush and Replacement

Over time, coolant can become contaminated or lose its ability to protect the engine from overheating. It is recommended to flush and replace the coolant at regular intervals, as advised in the manufacturer's manual. To perform a coolant flush:

1. Start by ensuring the engine is cool and the snowmobile is on a level surface.
2. Locate the coolant drain plug on the radiator or engine block. Use a container to collect the old coolant.
3. Remove the drain plug and allow the old coolant to drain completely.
4. Close the drain plug tightly once the coolant has drained.
5. Refill the cooling system with the manufacturer-recommended coolant and mix it with distilled water as specified in the manual.
6. Bleed the air from the system according to the manufacturer's instructions.

Thermostat Check

The thermostat plays a crucial role in regulating the engine's operating temperature. It opens and closes to allow or restrict coolant flow through the engine. A malfunctioning thermostat can cause overheating or poor heat dissipation. To check the thermostat:

1. Ensure the engine is cooled down before starting.
2. Locate the thermostat housing, usually positioned near the engine cylinder.
3. Remove the housing and inspect the thermostat for any signs of damage or corrosion.
4. Test the thermostat by placing it in a pot of hot water. It should open once the water reaches the specified temperature range mentioned in the manual.
5. If the thermostat does not open or falls outside the recommended temperature range, replace it with a new one.
6. Reinstall the thermostat housing securely.

Conclusion

Maintaining the cooling system of your Ski Doo 600 ACE ET is crucial for optimal performance and longevity of your snowmobile. Regularly inspecting and cleaning the cooling system components, performing coolant flushes, and checking the thermostat will help prevent overheating issues and keep your snowmobile running smoothly on the snowy trails.

Always consult the manufacturer's manual for specific guidelines and recommendations on cooling system maintenance for your Ski Doo 600 ACE ET.
