This is a new, genuine Kubota radiator assembly, part number 1E103-72060. Kubota engine dealers list it for three three-cylinder engines: the D722 and D902 Super Mini diesels and the WG972 spark-ignition engine. It is a separate Kubota part number from 1G952-72060, which is listed for the same three engines plus the Z482 and DF972, and from 1G951-72060, which is listed for the Z482 and D722.

Radiators are replaced for leaking tubes or seams, blocked fins, cracked tanks and broken mounts. Kubota lists more than one radiator for each of these engines and public catalogs do not show how they differ, so the part number on your old radiator is what decides it. Kubota’s own GL11000 and GL14000 generators, which run the D722 and D902, use other radiators: 1G292-72060 and 1G319-72060.

Specifications

Fits / Applications

• Kubota D722 three-cylinder diesel engine
• Kubota D902 three-cylinder diesel engine
• Kubota WG972 three-cylinder spark-ignition engine (gasoline, LPG)
• Direct replacement for a radiator numbered 1E103-72060. Other radiator numbers on these engines are different parts.

Before you drain the system, set the new radiator next to the old one and compare the hose necks, mounts, filler neck and shroud mounting points. Flush the system and refill with the coolant type and mix Kubota specifies for the engine. Replace soft or cracked hoses and weak clamps, and bleed trapped air before putting the machine back to work.

Frequently Asked Questions

Will the 1E103-72060 fit my Kubota D722, D902 or WG972?

Kubota engine dealers list it for all three engines. Each of them is also listed with 1G952-72060, so it is the right part only if your old radiator or parts book shows 1E103-72060.

What is the difference between 1E103-72060 and 1G952-72060?

They are separate Kubota part numbers listed for the same D722, D902 and WG972 engines, and 1G952-72060 is also listed for the Z482 and DF972. Catalogs do not show how the two differ, so order the number on your old radiator.

Is this the radiator for a Kubota GL11000 or GL14000 generator?

No. Kubota’s parts lists for those generators show 1G292-72060 on the GL11000 and 1G319-72060 on the GL14000, and both are separate part numbers from 1E103-72060.

What should I send you to confirm a 1E103-72060?

The engine model, the engine serial number and the number on your old radiator. If the engine is in a machine, add the machine make, model and serial number. Call 530-668-0818 and we will check it before you order.
