Oh crud.

First, you need constant tension hose clamps, not the screw band type. When I replaced my radiator, I used double on the coolant hose, since it is prone to leak, and hard to access. When you do reach the area, feel on the steel coolant pipes for a slight bulge. Obviously, the clamp should be on the outer side of the bulges.

You are going to think I'm nuts. I am a rather small guy, but I have accessed that area, without taking the fan motor out. If you stand and stare at the fan motor there is a 1 inch hose, mine is blue, that connects the radiator expansion tank to the water pump. I am not talking about the overflow tank.

If you remove both the overflow tank (four bolts) and you take that coolant hose loose from the expansion tank ( you have to drain the tank), and you get a step stool to stand on, then you can wriggle into the cavity between the engine and the hyd fan motor. It is not easy or comfortable, but it can be done. Tom is laughing his head off as he reads this.

You'll need a helper to hand you tools.

If you don't think you can get into that space, the alternative is to pull the fan loose from the fan motor, and leave it in the fan shroud. Take the four bolts on the bottom of the fan motor loose that hold it to the H mount. Move the fan motor up onto the exhaust manifold. Take the four bolts that hold the H mount (fan motor support mount) loose and remove it.

Now you can crawl into the cavity and do what you need to do.

You CANNOT reach this area by removing the engine access hatch in the bathroom. Been there, tried that.
