Vehicle Information
Ski-Doo Formula Z 500 Snowmobile (1999)
The 1999 Ski-Doo Formula Z 500 was a popular snowmobile, known for its spirited trail performance. It was powered by a 499cc (sometimes referred to as 494cc) liquid-cooled Rotax twin engine, producing approximately 95 horsepower. This engine, featuring the RAVE system, was considered relatively fresh for Bombardier at the time. For the 1999 model year, the primary trim was the Formula Z 500, but a Formula 500 DLX (Deluxe) was also available, sharing the same 499cc engine. The Formula Z line offered other engine sizes, including 583cc and 670cc. No major mid-cycle generation or platform changes were explicitly detailed for the 1999 Formula Z 500 within that specific model year. Only a minor adjustment to the clutch engagement speed was noted, changing from 3,800 to 4,100 RPM, according to a 2000 specification booklet. FAQ:

Maintenance
| Component | Interval | Details |
| Oil Filter (2-Stroke Engine) | Before every ride | 2-stroke engines use an oil injection system rather than a traditional filter. Check the injection oil reservoir level and top off as needed. Never run out of injection oil. |
| Drive Belt | Inspect every 50 hours or before every ride | It is recommended to start each season with a new drive belt. Visually inspect before every ride for signs of wear (cracking, uneven wear, flat spots, fraying). Typical lifespan is 2,400 to 4,800 km, depending on riding style. |
| Spark Plugs | Annually or more frequently | Replace annually before the season for moderate use. For aggressive or very frequent riding, replace more often (e.g., every 3rd or 4th trip). The recommended model is NGK BR9ES. |
| Air Filter | Inspect every 25 to 50 hours | The Formula Z 500 uses an 'Air Silencer Ass'y'. Inspect every 25 to 50 hours in normal conditions. More frequently in dusty or muddy environments. Replace if dirty after cleaning, if seals are cracked, or if exposed to water. |
| Coolant | Change every two years; check before every ride | Change coolant every two years. Check the level when the engine is cold before every ride. A full flush is recommended every 4 to 5 years. |
The maintenance intervals below are based on various sources and may not be 100% accurate. It is strongly recommended to consult your official 1999 Ski-Doo Formula Z 500 owner's manual for the most precise and model-specific information.
