question on replacing radiator fan motor
I'm reviewing the Helms manual and the process appears quite simple. I'm going to replace the failed motor in the secondary fan. All I need to do in order to pull the fan assembly is to remove the 4 retaining bolts from fan assembly to the fan shroud, and disconnect the fan connector.
What I don't understand is the need to raise the vehicle. Can anyone explain the necessity of this part of the procedure?

I'm trying to remember from when I did mine, but I believe that it is easier to remove the shroud from the bottom than from the top.Then replace the bad motor and reinstall the shroud from the bottom. Good luck, Robert

Robert, one thing.......the Helms said nothing about removing the shroud --- just the fan assembly(ies) unbolting the 4 bolts to the shroud. This is why I'm dumbfounded as to why the car needs lifted.
I realize this is all kinda moot, part of my point is to show that the Helms manual is NOT the god folks think it is. There's stuff that SHOULD be in there, as well as items that definitely SHOULD NOT, including outright errors.
Then when you get to the electrical stuff, it halfway outright SUCKS.

I did one on my 90...It's been a while though.
I replaced one of the fan motors on my 90. I didn't raise the car that I can remember. I did have one of the bolts that was a bit of a pain to get to. I wonder if that is why they want you to raise the car. That way the inside botom bolt is easier to reach.

HR90; I replaced the passenger side motor on my 91 last year. The reason it suggests to lift the car is because getting to the assembly retaining bolts (4) is easier for 3 of them from underneath, if I remember. In addition the whole assembly drops out from the bottom. I had to loosen up another on top part, which I can't remember now and although it doesn't look like it will drop out, it does. You then can R&R the motor on the bench.
Make sure you're getting power to the motor through the hot lead. If not you may have blown the fuseable link behind the battery. This could have burnt out because of a bushing failure which put an abnormal drag on the motor. Just my 2 cents. Good luck! Frank

Just a thought, on my 91 the AC accumulator would be in the way to prevent removing the secondary fan assembly from the top This may be why the FSM says raise the vehicle so it could be removed from the bottom.

Every thing in the manual starts with. "Disconnect the battery and raise the car" Even if you're only changing underwear.
I only use the Helm for diagnostic flow charts and circuit diagrams. The "How to's" on turning wrenches are kinda pointless. Remove the bolts to get the fan off... Uh, no **** sherlock!
The section on rebuilding the tranny was somewhat useful, but still over the top, and with unnecessary steps.
