Vehicle Information
Arctic Cat Panther 370 Snowmobile (2001-2008)
The Arctic Cat Panther 370, a popular touring-style snowmobile, was produced from 2001 to 2008. It was known for its reliability and comfort, offering an enjoyable riding experience for trail excursions. Initially equipped with a 339cc engine in 2001, the Panther 370 received a significant update starting in 2002. Models from 2002 to 2008 were powered by a 367cc, air/fan-cooled, horizontal in-line, 2-stroke engine with a reed valve configuration. This 367cc engine produced approximately 36 horsepower, as noted for the 2003 model, and maintained similar specifications for subsequent years. These models typically featured a CVT transmission with reverse, an Independent Double Wishbone Front Suspension, and a FasTrack Rear Suspension, along with comfort features like heated hand grips and a seat backrest. The Panther 370 was primarily offered as a single touring model, without major distinct trim levels. Q: How can I ensure this part fits my Arctic Cat Panther 370?
A: To guarantee compatibility, please use the year and model selector available on this page.
Maintenance
| Component | Interval | Details |
| Injection oil level | Regularly | For 2-stroke engines, check the injection oil reservoir level and use manufacturer-recommended oil. |
| Drive belt | Regular inspection, replace if worn/damaged | Break-in of approximately 40 km for a new belt. Some users report a lifespan of 1,600 to 3,200 km or more, depending on use and conditions. |
| Spark plugs | Before each season (moderate use) | Replace more frequently with intensive or aggressive use. The owner's manual specifies the exact spark plug type (e.g., NGK BR9EYA). |
| Air filter | Every 10-12 hours or if dirty | Inspect and replace if damaged or excessively dirty. Clean more often in dusty or extreme conditions. |
| Coolant | Every 2 to 5 years | Or whenever the cooling system has been drained for maintenance or repair. Use manufacturer-recommended coolant. |
