sorry if this is in the wrong spot. and either my search isnt working for me or there just isnt one posted. but where can i get some instructions on how to remove the fan assembly? is it a major headache? im on the cusp of replacing my alternator and im not too keen on the idea of removing the PS pump or the PS pulley if i dont have to. and i was told it could be done by just pulling the air intake and fan assembly to make the room

The ps pulley is pretty easy to remove and you can rotate the ps reservoir to give you the room you need. I think pulling the fan and shroud would be more difficult than the ps pulley.

Just take off 4-ish bolts holding fan shroud and I believe 3x bolts that hold trans cooler lines to the shroud. Also, TB and belly pan needs to come off and 2x fan connectors, one on left and one on right side, after that you should be able to lift the whole thing up and out of the bay.
All the bolts are 10mm if I remember correctly.

I have this half-assed service manual USB with minimal detail and crude illustrations that I bought on Ebay or Amazon. It's somewhat useful for certain things. And it said to pull the air intake, pull the plastic sight shield above the fan assembly, detach the connectors, detach a retaining clips holding lines in place, then it showed like 4 screws holding it in place. It seemed fairly simple (which was my concern). That's why I asked. To see if theres ginna be any huge hurdles to prepare for. I take the info on the USB with a grain of salt, more like a guideline. But I'm gonna check it out tomorrow. And if it seems just as straightforward as that I'm gonna go for it. If not, then I'll check out the PS route. I do have a pulley removal/installation kit if need be. But ive pulled the harmonic balancer off my old LY7 Caddy before and it wasn't something I "enjoyed" doing. So PTSD got me trying to avoid that avenue if possible lol. But we shall see depending on how my energy levels are tomorrow. Thank you guys

This, 4 bolts, plus the trans cooler lines and easy as pie. The bottom of the fan also has the pinch clips that secure to the bottom of the radiator.

Your biggest PITA is draining the coolant since our cars do not come with a petcock valve.

This for sure.


The fan shroud has always been a royal PITA for me. Engine coolant and trans fluid lines plus intake and harness connections. That upper radiator hose is a bitch.

I'd definitely try to tie the PS pump off to the side with wire or zip ties and attack the alternator from top and bottom first. With the intake out of the way it should come out.

And, as an added bonus, by leaving the fan shroud in place you lessen the risk of having to replace the radiator if you happen to drop say, a bolt that bounces against the cooling fins.

Cut a piece of cardboard to protect the radiator if you do remove the shroud.

You will for sure want to pull the PS pulley (and some pullers will be tight on the fan shroud, but it's doable) and pump out of the way. Take the brackets along with the long stud off also. There is a bracket that attaches to the ac suction line that is down low you will need to remove it also. Also make sure you have the battery (pos) disconnected so you dont weld. I've learned, that on this car taking a few extra items off or out of the way will make the overall job much easier and less likely for you to want to kill someone half way through. I'd recommend a quality aftermarket or AC Delco replacement, because you DO NOT want to do this twice!!
Good Luck
