Kubota GL-43 Coolant and Engine Notes
| Coolant capacity note | For the Kubota GL-43, 2.17 gal (8.2 L) is the main coolant capacity captured. Use it as a refill planning number, then confirm the final level at the machine |
|---|---|
| Radiator capacity note | The Kubota GL-43 radiator figure is 2.17 gal (8.2 L). Treat it as radiator context, not always the complete refill amount |
| Coolant type note | Coolant type for the Kubota GL-43 is listed as ethylene glycol-based coolant. The safest move is to use coolant that matches the manual’s spec rather than mixing random formulas |
| Antifreeze mix note | The Kubota GL-43 antifreeze mix is listed as 50/50 coolant and water mix. That is the normal protection range for freezing, boiling and corrosion control |
| Engine context note | For the Kubota GL-43, the supporting engine specs are engine model D1503-TI, engine horsepower 43 hp (32.1 kW), and displacement 1.5 L (91.5 cu in). Use them as context beside the coolant capacity, not as a replacement for the manual |
| Refill note | When refilling the Kubota GL-43, use 2.17 gal (8.2 L) as the planning number and 50/50 coolant and water mix as the mixture guide. Recheck the level after the thermostat opens |
Kubota GL-43 Coolant Capacity FAQ
How much coolant does the Kubota GL-43 take?
The main coolant amount captured for the Kubota GL-43 is 2.17 gal (8.2 L). Buy a little extra so you can top up after the engine warms up and cools down.
Does coolant type matter on the Kubota GL-43?
Yes. Capacity tells you how much to buy; coolant type tells you what to buy. For the Kubota GL-43, the captured coolant type is ethylene glycol-based coolant.
What antifreeze mix does the Kubota GL-43 use?
The captured antifreeze mix for the Kubota GL-43 is 50/50 coolant and water mix. A 50/50-style mix is the common practical answer unless your manual or climate calls for something different.
When should the Kubota GL-43 coolant be replaced?
Use the service interval in the operator manual as the service guide. Coolant can look okay but still lose corrosion protection over time.
What engine specs affect Kubota GL-43 coolant capacity?
The captured engine context is engine model D1503-TI, horsepower 43 hp (32.1 kW), and displacement 1.5 L (91.5 cu in). Engine size is one reason coolant capacity changes between tractors.
Mistakes do happen. Tractor coolant specs can change by year, market, engine, radiator, cab/heater setup and service procedure. Please check the operator manual, decal information and official kubotausa.com website for official information before draining or refilling the cooling system.
