Kubota L4300 Coolant and Engine Notes

Coolant capacity note For the Kubota L4300, 2.2 gal (8.3 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 Coolant type for the Kubota L4300 is listed as ethylene glycol-based coolant, Kubota Genuine Coolant, and ASTM D3306 compatible. The safest move is to use coolant that matches the manual’s spec rather than mixing random formulas
Antifreeze mix note For the Kubota L4300, 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 L4300: engine horsepower 45.3 hp (33.8 kW) and displacement 2.2 L (134.3 cu in). Engine size helps explain why coolant capacity changes between models
Refill note When refilling the Kubota L4300, use 2.2 gal (8.3 L) as the planning number and 50/50 coolant and water mix as the mixture guide. Recheck the level after the thermostat opens
