How to Replace Tensioner 2000-08 Chevy Tahoe

You remove this cover. There's a bolt right here. Use an 8-millimeter socket. Take that out. Then slide the cover up and slide it forward. There's a bracket right here that holds the coolant hoses on. Just use a trim tool and just separate that from that. This one's broken in this vehicle. Now we wanna remove this snorkel and use an 8-millimeter socket. Loosen up the worm clamp. Or you can use a straight blade screwdriver. So right here.

And slide this off. And slide it off the throttle body. And pull it out of your way. And use a 15-millimeter wrench or you can use a belt tensioner tool and just put it on the belt tensioner. Loosen this up. Slide the belt off of the idler pulley. Loosen up on the tensioner and slide the belt off the alternator, off the power steering, pump pulley, off the water pump and off the crank pulley. Now use a 15-millimeter socket and there's 3 bolts holding the tensioner on. Take those three bolts out. And slide that out. All right. Take the new tensioner and you have those three bolts. Two of them are longer. One of them is shorter. And the longer ones go on the longer part of the bracket. The shorter one goes on the shorter part.

And I'm gonna torque these bolts to 37 foot-pounds. Right. Take the serpentine belt and slide it over the crank pulley first. And go over the water pump. The back side of the belt needs to go over the water pump. And go down to the power steering pump. And up over the alternator. And then over the tensioner right here. Then you hold off on putting it over the idler pulley till last. And now take your belt tensioner tool or a wrench and just take the tension off the tensioner. Right. Now I'm gonna slide the belt close to the idler pulley and take the tension off the tensioner with your wrench or your belt tension tool. Just be careful. And take the wrench off and just doublecheck all the pulleys. And it looks good.

Now take the intake snorkel and line this up with the throttle body. And that's good there. And line it up on the mass airflow sensor. Just like that. And tighten this up. Tighten up that worm clamp and then same with this one. And take this bracket and then reposition that into that bracket. This one doesn't...this one's broken. And slide this cover back on. Get this bolt started. And tighten that up.
