Vehicle Information
Arctic Cat EXT 600 Snowmobile (1997-1998)
The Arctic Cat EXT 600 snowmobile, available from 1997 to 1998, was a popular model in its segment. It was consistently powered by a robust 594cc liquid-cooled, triple-cylinder Suzuki engine across these model years. This engine, also notably featured in other performance-oriented Arctic Cat models like the ZRT 600 and Powder Extreme, was highly regarded for its smooth power delivery and strong, reliable acceleration, generating an impressive 118 horsepower. A key characteristic of the EXT 600 during this period was its remarkable consistency. The model did not undergo any significant mid-cycle generation or fundamental engine changes between 1997 and 1998; the core 594cc triple-cylinder unit remained unchanged. While the primary trim, the EXT 600 Triple, was offered in both years, 1997 also saw the Powder 600 Extreme utilizing this same engine. For the 1998 model year, Arctic Cat introduced the EXT 600 Touring, a new variant designed with a focus on enhanced features and ergonomics for longer rides, rather than a modification to the underlying engine or platform. Q: Is this product compatible with my Arctic Cat EXT 600 (1997-1998)?

Maintenance
| Component | Interval | Details |
| Oil Filter | Not applicable | As a 2-stroke engine, the Arctic Cat EXT 600 does not use a traditional engine oil filter. Ensure the oil injection reservoir is kept filled with recommended 2-cycle oil. |
| Drive Belt | Inspect daily/monthly. Replace if damaged or worn. Proactive replacement every 1 600 km. | Inspect for cracks and tears. A break-in procedure of 30 km at speeds below 80 km/h is recommended for new belts. Lifespan varies significantly based on riding conditions. |
| Spark Plug | Inspect, replace, or clean as necessary. Annually. | Spark plug gap is specified as 0.7 mm for all models in this range. |
| Air Filter | Inspect every 25-50 hours or after dusty/muddy conditions. | Snowmobiles typically use an airbox rather than a conventional paper air filter. Clean and re-oil foam filters if present, and ensure the airbox is kept clean to prevent dirt ingress. |
| Coolant | Check level and hoses regularly. Replace every 2-5 years. | Check all coolant hoses and connections for deterioration or cracks. Add properly mixed coolant as necessary. |
