That is indeed a very good price for the fan motor, but just because your temp gauge
is going a little above the LED doesn't necessarily mean it is overheating.
Your description of the sound, though, does make the motor suspect.
When I replaced mine, it wasn't making any abnormal noise under normal conditions, but
only when the A/C was operating and I had been driving for a while. Then when it went
on hi-speed, it sounded like an AC-130 gunship. I first tried removing and
disassembling the motor and oiling the bearings, but that didn't help, so I bought the
new motor (at great expense), and guess what? It still makes the same noise!.
Removing the fan motor is moderately difficult. You need to lower the radiator about
half way so you can remove the shroud, but you can do it without disconnecting any
coolant or A/C hoses.
You will also need to swap the fan blade over to the new motor. Mine came with a
blade, but it was the wrong size.
Good luck,
Jerry
