Kubota BX1870 Coolant and Engine Notes
| Coolant capacity note | For service planning, the Kubota BX1870 should be treated as 1.65 gal (6.2 L) coolant capacity. That is a compact tractor cooling system where a normal premixed coolant jug may cover most of the refill |
|---|---|
| Radiator capacity note | For the Kubota BX1870, the captured radiator capacity is 1.64 gal (6.2 L). If you are doing a full drain, check the full cooling-system capacity too |
| Coolant type note | Use the right coolant formula for the Kubota BX1870: ethylene glycol-based coolant and Kubota Genuine Coolant. Cheap wrong coolant is not a smart saving if it causes corrosion or deposits |
| Engine context note | Engine context for the Kubota BX1870: engine horsepower 18 hp (13.4 kW) and displacement 0.7 L (43.9 cu in). Engine size helps explain why coolant capacity changes between models |
| Refill note | Coolant changes are simple but easy to do sloppily. On the Kubota BX1870, plan around 1.65 gal (6.2 L) and confirm the final level after air works out of the system |
