Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we show you how to replace the primary radiator fan. As you're looking at the engine from the front of the car, it's the fan that's on the right side. This is a '97 Buick LeSabre. This fan and the procedure is basically the same for most GM B- and C- body vehicles, which are the Pontiac Bonneville, Olds 88, Olds 98 Buick LeSabre, Park Avenue, as well as Cadillac DeVille. The tools you'll need are a 10mm socket and ratchet, jack and jack stands, and a screwdriver.
We just start out underneath. You will want to lift up the vehicle. You might be able to get to this without having to lift it up, but it's probably easiest just to jack up the vehicle, secure it, and remove a few 10mm bolts, and let this splash pan down.
There are now three bolts: one that holds the right hand fan there, and then two that hold the left hand fan right there and there. You'll have to loosen up the bracket for those transmission lines. The transmission lines are in the way of the right side bolt here, so we're going to loosen up on the plastic bracket, and it's, as well, a 10mm bolt. Pull that down a little bit and that will get you the room you need to get to that bolt. Up top, there are two 10mm bolts here and here. I am just going forward here as we remove those two top bolts. This is the clip that holds the harness in, and this is your connector. With a flat blade screwdriver pocket, just give a little pry on the tab and it should come right out. Here's your harness and the connector that we're going to take apart now. We'll start by removing that white clip. Lift up on the tab and push it out. Locate the two upper 10mm bolts on this one. Then we will fast forward here. The one on the left side, as you're looking at the engine, is easy. The one on the right side you just have to push down on the air box deflector a little bit and work the wrench in there, loosen it up, and then get it the rest of the way out with your fingers.
As you can see, we have put the radiator fan down in and Don was looking down to make sure that the lower ones were going into the right spot as well, and now he's starting in the upper bolts, and he'll tighten them up. I must set this target here. Yeah, it's good. Reconnect the harness and reinstall the white safety tab. You can reinstall the fan. Make sure your harness is out of the way, and, when you put it down, make sure the bottom one . you can see it from up here . is on the outside, or towards the engine of the radiator shroud. Reinstall the connector. Reinstall the lower two bolts. We will speed it up, here, as we reinstall those bolts, tighten them up, and then remember to tighten up that bracket that holds the transmission. Speed up here. We slot the two bolts in; just make sure you don't cross thread them, and then tighten them up. Then finish up by reinstalling the bolt for the backup A/C condenser fan, and then put the splash shield back up in place, and bolt it in.
