Cub Cadet 122 Coolant and Engine Notes
| Coolant capacity note | For the Cub Cadet 122, 0.93 gal (3.5 L) is the main coolant capacity captured. Use it as a refill planning number, then confirm the final level at the machine |
|---|---|
| Coolant type note | Use the right coolant formula for the Cub Cadet 122: ethylene glycol-based coolant. Cheap wrong coolant is not a smart saving if it causes corrosion or deposits |
| Antifreeze mix note | The 50/50 coolant and water mix mix gives the Cub Cadet 122 coolant system a sensible balance of freeze protection, boil protection and corrosion protection |
| Coolant change interval note | The captured coolant change interval for the Cub Cadet 122 is every 2 years. Old coolant can lose corrosion protection even if the tractor still runs cool |
| Engine context note | The Cub Cadet 122 engine data captured here is engine model K301, engine horsepower 12 hp (8.9 kW), and displacement 0.5 L (29 cu in). Bigger engines usually need more coolant and more careful refill bleeding |
| Refill note | Coolant changes are simple but easy to do sloppily. On the Cub Cadet 122, plan around 0.93 gal (3.5 L) and confirm the final level after air works out of the system |
