Kobelco SW2489U268F1 is the coolant temperature sender: a brass hex body with a male thread, a brass probe and a single spade terminal. It is used on Kobelco SK200-3 and SK200-5 excavators. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Wrong or missing reading
A failed sensor gives a dead or false gauge reading or a warning light.
Fault codes
Check the wiring and plug first; if the sensor itself reads out of range, replace it.
Corrosion
Connectors on machines take water and dirt. A corroded sensor is cheaper to replace than to chase.
Fleet spares
Common sensors are worth keeping in stock for each machine type.

Yes, it was made for the Kobelco ED180, and 10 more listed under compatible equipment. Check the old sensor is marked SW2489U268F1 or one of the cross references, because makers change parts between serial ranges.
On the Kobelco ED180, there is no fixed interval. It is changed when it fails, and many fail from water in the plug or chafed wiring rather than wear.
A fault code for this circuit, readings that jump or stay fixed, or a part that does not respond with power at the plug.
Yes. Many machines have 12 V and 24 V versions of the same sensor. Check the old part or the machine plate before fitting.
Usually. Clear them after fitting and run the machine, so old codes are not mistaken for a new fault.
No. It is an aftermarket sensor made to replace the Kobelco SW2489U268F1. It is not made by the original manufacturer; the number only shows what it replaces.
