Assuming it is the same as our 2166.... our 9230 Steiger and 2166 are the same, so I'm guessing all 8.3 are.
Very easy to change, just three bolts which can be accessed without any other disassembly, just reaching around from the rear. Draining the radiator was the longest part of the job. All said and done it was about 1/2hr from first cracking open the radiator drain to having it topped up and combining again.
They are very cheap too, I think the last one cost about $80, you might as well just do it.
