Kubota GL32 Coolant and Engine Notes
| Coolant capacity note | The headline cooling-system number for the Kubota GL32 is 2.17 gal (8.2 L). Buy enough coolant before opening the drain plug |
|---|---|
| Coolant type note | The captured coolant type for the Kubota GL32 is ethylene glycol-based coolant and ASTM D3306 compatible. Do not mix unknown coolant types unless the label and manual say they are compatible |
| Antifreeze mix note | For the Kubota GL32, the captured mix is 50/50 coolant and water mix. Straight water is not the right long-term answer unless you are only flushing the system |
| Engine context note | Engine context for the Kubota GL32: engine horsepower 31 hp (23.1 kW) and displacement 1.5 L (91.5 cu in). Engine size helps explain why coolant capacity changes between models |
| Refill note | For a coolant change on the Kubota GL32, do not just dump in coolant and walk away. Fill slowly, run it up to temperature, cool it down and top up as needed |
