When i went looking for a Sportage here in the US i never saw any diesel engine versions, so i would guess that they are not sold here??? My fan clutch is acting up as well so i am trying to get my paws on the SPAL controller and fan to convert it to electric fan system. There are several write ups on this forum and others about making that conversion. The problem i have with it is that the cost is about $200-220USD from ebay for both. In your case that would be a big savings all the way around. I haven't found any good wiring descriptions or diagrams on line yet and hope that the SPAL i ordered has good instructions with it. The big advantage to electric fan would be that there is a lot less drag (on the gas engine any-way) increasing MPG and free up some HP. The truth is that i don't know what difference it would make on a diesel, but worth at least researching for yours. Sorry that i don't have access to information on if there are different clutch fan types.
Good luck.
