Kubota KL380 Coolant and Engine Notes
Coolant capacity note
The Kubota KL380’s key coolant figure here is 2.17 gal (8.2 L) for coolant capacity. Use that before buying coolant or draining the system
Radiator capacity note
Radiator capacity is listed as 2.17 gal (8.2 L). The full cooling system can be higher because coolant also sits in the engine and hoses
Coolant type note
Use the right coolant formula for the Kubota KL380: ethylene glycol-based coolant, long-life coolant, and ASTM D3306 compatible. Cheap wrong coolant is not a smart saving if it causes corrosion or deposits
Engine context note
The Kubota KL380 engine data captured here is engine model D1803 and engine horsepower 38.5 hp (28.7 kW). Bigger engines usually need more coolant and more careful refill bleeding
Refill note
Coolant changes are simple but easy to do sloppily. On the Kubota KL380, plan around 2.17 gal (8.2 L) and confirm the final level after air works out of the system
Kubota KL380 Coolant Capacity FAQ
What is the Kubota KL380 coolant capacity?
The Kubota KL380 coolant capacity is listed as 2.17 gal (8.2 L) for coolant capacity. Use this as the refill planning number and confirm the final level at the radiator or overflow bottle.
Can I use any coolant in the Kubota KL380?
No. Use ethylene glycol-based coolant, long-life coolant, and ASTM D3306 compatible or a coolant that clearly matches the manual’s required spec. Wrong coolant can create corrosion, deposits or seal problems.
Is premixed coolant okay for the Kubota KL380?
Premixed coolant can be fine if it matches ethylene glycol-based coolant, long-life coolant, and ASTM D3306 compatible and the required mix. The captured mix for the Kubota KL380 is the coolant mix specified in the manual.
How often should I change coolant in the Kubota KL380?
The captured coolant change interval for the Kubota KL380 is the service interval in the operator manual. If service history is unknown, changing it is usually smarter than guessing.
What engine specs affect Kubota KL380 coolant capacity?
The captured engine context is engine model D1803 and horsepower 38.5 hp (28.7 kW). Engine size is one reason coolant capacity changes between tractors.
Official information note
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.
