It looks very similar from your picture but I can't tell for sure if they redesigned the oil cooler or mounting. The Kioti CK25 and 30, twins of the CT225 and 230, had these issues. I replaced one under warranty and then another after warranty on my CK30hst. About 125 and 100 hours respectively. If the cooler is still mounted with two studs and nuts going through the top of the cooler to a horizontal support in front of the radiator, then the trick is to mount it with rubber grommets. I had drilled the holes in the cooler a little larger, placed a rubber grommet in each hole, cut two 5/16" long by 1/4" diameter steel tubing sections to go into the grommets and then passed the steel tubing over the studs with the nuts tightening down on the steel tubing. It relieves much of the vibration and I'm still good with 150 hours on the cooler. Other Kioti owners of these models had to do the same with good results.
