In this video, we're going to show you how to replace the idler pulley on this 2000 Lincoln Town Car with a 4.6 liter V8. Tools you'll need are an 8mm wrench, a 3/8 inch ratchet, and a 13mm socket.
With an 8mm wrench, disconnect your negative battery cable.
Before you remove your belt, you want to make note of how it's routed. There should be . on most vehicles, there's a belt routing diagram, but I don't see one on this Town Car. You can see that it goes down around your crank pulley way down there, around the power steering pulley like that, then up to the alternator, around the idler pulley, down to the A/C pulley, then back up to the tensioner, and then around the water pump and down. Removing the belt's quite simple. Right here is your tensioner. It has a 3/8 inch hole in it right here. We can put a ratchet handle and then you want to move it clockwise. You can see the belt loosens up. You can take the belt off the alternator, and slowly let your handle back. Pull it out. You don't have to remove the belt all the way, but I do just to kind of get it out of the way for filming at least.
Your idler pulley is right here. Mine's actually in good shape, there's no play in it or anything but it's easy enough to replace. Use a 13mm socket and ratchet. Remove the idler and reinstall it.
Make sure you have your washer and everything on your bolt. Put it back on. Tighten it.
I'm not going to be able to really film this that well, but I'll try and explain what I'm doing. I'm going to take a loop like this, and then I'll put down and around the air conditioning compressor and put down here on the passenger's side of the motor, and move it on there. Then I'll bring that right around my tensioner, and then, from there, bring this side up around my idler pulley. This then goes down around my water pump here, and then around the crank pulley, the largest center pulley. I'm going to leave this off of my alternator and then put it and around my power steering pulley. I've pretty much got everything in place. I've got the belt on all my pulleys except for my alternator. So, I can put my wrench on my tensioner, pull my tensioner all the way over. Belt comes up and around my alternator. I'll pull my tensioner off. Re-check the belt in all the locations. It looks good. Reconnect and tighten up your negative battery cable, and you should be good to go.

In this video, we're working on this 2001 Chevy Malibu, and this repair is basically the same for any '97-'03 Malibu with the 3.1 liter. We're going to be looking at the serpentine belt idler pulleys, checking them, seeing if they're okay, and then if need be, replacing them. Tools you'll need are a jack or engine hoist, 15mm and 18mm sockets with ratchet and extension. You need a 3/8 inch drive, and you either need a flexible bar or the ratchet handle.
Your serpentine belt is obviously right here on the passenger side of your engine. What you actually need to do is remove this engine mount, which involves removing two 18mm bolts here and two 15 mm nuts, one there and one down there. That is the engine mount, so you either need to support here with an engine crane, or you need to use a jack and support underneath the oil pan here. Do not jack the car up yet. You actually just want to support the weight of the engine. Spray some penetrating oil on those studs down lower, and I've cheated a little bit, with a 15mm socket and an impact wrench. No reason you can't reach everything pretty easily with just a regular ratchet and extension. I've got my 18mm socket on here. I'll loosen up one of these bolts. I'm going to start loosening the other bolt, and you're going to see the engine falling, which is actually more the car rising. What you want to do now is take your jack, and jack the engine up. Now it's supporting the engine. You can remove these bolts the rest of the way. For this mount, slide it back and right out. I'm just going to remove these two lines, just to make it easier for you to see.
Now, what you want to do is take your jack, and jack the engine up a little bit extra. Now right down in here is your tensioner. What I have is a little flex arm. What you want to do with this flex arm is put it down; there is a 3/8th hole at the bottom of the tensioner. You want to put it in, just like that. Here is my bar. I'm going to reach in, and I'm going to pull the bar up, which pulls on the tensioner. It releases the tension on the belt, and you can pull the belt off and then slowly release your bar back down. Be careful not to pinch your fingers. Take the bar out, and then just take your belt off of all the pulleys.
There are two idler pulleys on here: one here and then one right down here. To test those, spin them, listen for any noise, try and shake them back and forth to see if there is any play in them at all. If you do want to change the idler pulley, remove a 15mm bolt and the pulley comes off. I see the idler's in okay shape so I'm going to put it back on, and the same goes for the one down there.
Here is your belt routing diagram. This is key. Make sure you have this before you take the belt off. If you don't have this, make sure you draw yourself a diagram similar, so you can get the belt on again. It's kind of hard to film this, so you're just you're just kind of have to take my word that I'm doing what I'm saying I'm doing. Take your belt, and you want to put a loop down underneath the crankshaft, which is the lowest, largest pulley and then the A/C compressor, which is the pulley that's lowest and closest to the front of the vehicle. It comes up, under this power steering pulley, and right up over here. Now, I'm going to reach down and I'm pulling it back to this idler pulley here, and then around under the tensioner pulley, and then I can pull it up on top of my alternator right here. Now, I'm all routed except for this idler pulley. Now, I'm going to take my 3/8th bar and get down in to my tensioner. Use both hands. Pull the bar up, grab on to my belt here and slip it under the idler pulley and let my tensioner go. I'm off a little bit here. Now check to make sure your belts on correctly everywhere. It's not quite on my crank pulley correctly. Pull up again on the tensioner, reach down and kind of flip it a little bit. Now it's on there correctly. It appears to be on everywhere correctly.
We're just going to kind of speed through putting this stuff back in. Put the mount back down in there, and then you can let your engine down just a little bit. Start the two top bolts on the mount and kind of preliminarily tighten them up. Then, you can let the engine all the way down. Take the jack out. Then start your 15mm nuts on top and preliminarily tighten them as well. Here I'm just reconnecting those hoses that I moved out of your way. Use a wrench. Make sure the mount bolts are tight, but not too tight.
