I'm pretty certain the fan is on the backside of the radiator (enclosed within the counterweight with the hydraulic pump) on this model Mitsi.
But I'm in agreement about removing the radiator.
I mean, even if you knew you had exactly 1/4" clearance in which to slip the engine out after bringing it away from the trans, why risk holing a radiator?
I cases like this, moving an easily damaged component out of the way is good insurance, and usually the fastest and cheapest way to go.
I see/hear of people always talking it up about how something or the other does not have to be removed to do this or that.
But if you look at getting something completely out of any harm's way, that's often the best money making/saving route to take.
