This is the genuine Kubota thermostat for the V3300, V3600, V3800 and V3307 diesel engines and the WG3800 gas and LPG engine. It replaces the older numbers 1C011-73010 and 1C010-73010. Kubota machines that use it include the M6800, M8200, M9000, M8540, M9540, M5-091, M5-111, M6-101 and M6-111 tractors, the SVL75, SVL90, SVL95-2s and SVL97-2 track loaders and the SSV75 skid steer.

Replace it when the engine runs cold, is slow to warm up, or runs hot with a full, clean radiator. Kubota uses several thermostats that look alike, and a few machines used two different ones over their production run, so match the number on your old part or have the engine model and serial number ready.

Frequently Asked Questions

Does the 1C011-73013 replace the 1C011-73010 thermostat?

Yes. Kubota’s parts lists show 1C011-73010 on earlier engines and 1C011-73013 on later ones, and 1C011-73013 is the current number for both. It also replaces the earlier 1C010-73010 found on M6800, M8200 and M9000 tractors.

Which Kubota engines take this thermostat?

The V3300, V3600, V3800 and V3307 diesels and the WG3800 gas and LPG engine. Kubota’s own parts lists show it on each of those. Kubota’s parts list for the newer V3800-TIE5 build shows a different thermostat, so check that one by serial number.

Will it fit a V2607?

It depends on the machine. Kubota’s V2607-DI-T parts list shows a different thermostat, 1G772-73012, and dealer catalogs list that one for the SVL65-2 and SSV65. The same catalogs list 1C011-73013 for the KX057-5, U55-5, R530 and R540. Call 530-668-0818 with your serial number before you order.

How do I confirm the fit for my machine?

Match the number on your old thermostat, or give us the engine model and serial number from the engine tag and we will check it against the Kubota parts list.
