Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!
Before I take the belt off, I want to loosen these four bolts that are holding on the water pump pulley. The belt is holding the pulley in place so it doesn't spin on me as I loosen them. Don't have to take them off all the way. Just to loosen them. These are 13 millimeter. There is a special tool that goes in here and can hold the pulley but if you don't have that, using the belt tension to hold it is a good way to remove it. It still wants to spin but you can usually get them loose. Let's see here. There it goes.
I'm using a 1/2" breaker bar with a 3/8 drive adapter. I'm going to put it in here, in the end of the auto belt tensioner. Pull it this way, pull the belt off, and let the tension go. Pull the belt off all the pulleys.
Again this is a 13 millimeter. Put those bolts aside. This may be rusted on here a bit. We'll try to remove it, see if it comes off. We'll put one of the bolts back in place to hold it. Take a dead bolt hammer and try to knock it free. Remove that bolt that was holding it.
To reinstall our water pump pulley, get it lined up. Right now you can also make sure that the water pump spins freely which it does. Line it up like that, and line up our pulley to match. I'm just going to hold onto the pulley and just tighten these down.
The pulley is reinstalled. If you don't remember how the belt was routed on the engine, there should be a diagram under the hood.
We're working on the V6, so we're going to use this diagram here. Put this this way, then up around the power steering pump, up and over the water pump, under the idler, over the crank pulley, up and over the alternator, then the A/C compressor, the power steering pump.
I need to flip this tensioner down. What I'm actually going to do is pop it off the alternator real quick and I can just hold it in place, grab the tensioner, pull it down, pop it back up onto the alternator. Make sure it's seated in the tensioner grooves. Let the tensioner out. The belt is seated in all the grooves. It's actually not lined up perfectly on the water pump pulley, so I want to just readjust it. So release some of the tension and I can slide it over. There, it's nice and straight and aligned now. Let the tension back out, and the belt is replaced.
