Cub Cadet 108 Coolant and Engine Notes
| Coolant capacity note | The Cub Cadet 108 coolant spec points to 2.51 gal (9.5 L). Do not rely on the radiator-only amount if the full cooling-system capacity is available |
|---|---|
| Radiator capacity note | The Cub Cadet 108 radiator figure is 2.51 gal (9.5 L). Treat it as radiator context, not always the complete refill amount |
| Coolant type note | Use the right coolant formula for the Cub Cadet 108: ethylene glycol-based coolant. Cheap wrong coolant is not a smart saving if it causes corrosion or deposits |
| Engine context note | For the Cub Cadet 108, the supporting engine specs are engine horsepower 10 hp (7.5 kW) and displacement 0.4 L (23.9 cu in). Use them as context beside the coolant capacity, not as a replacement for the manual |
| Refill note | Coolant changes are simple but easy to do sloppily. On the Cub Cadet 108, plan around 2.51 gal (9.5 L) and confirm the final level after air works out of the system |
