It was not toodifficult, if you have room thru the engine cover. One of the, 13mm I think, bolts was a little close, but it came out OK. Mine was not overheating, per the digital Scanguage, but mt goal was to reduce the cycles of that d@#$n clutch fan. If you are overheating at idle I would suspect the clutch fan is bad. You should be able to hear it come on way before you boil over. I also have to clean my radiator regularly as the hydraulic unit for the slides and jacks are right in front of the radiator and various minor leaks coat the fins.
