How do I losen the serpentine belt on a 1989 Suburban?

I am trying to change the water pump and can't work out how to loosen the serpentine belt. Any help is appreciated. Thanks.How do I losen the serpentine belt on a 1989 Suburban?
You need the following tool: Sears and any auto parts store has a serpentine belt tensioner removal tool. It's a 1%26quot; wide by 3/16 bar - 24 inches long. It has a raised 3/8 square drive on one end with several shallow metric and crows foot metric wrench ends that will fit every belt tensioner out there to ease the tension spring inside the pulley housing so you'll easily be able to remove and reinstall the belt after changing the water pump.How do I losen the serpentine belt on a 1989 Suburban?
there should be a belt tensioner on it. you put a ratchet in it and move it and it loosens. take it to autozone and they'll tell you for sure.How do I losen the serpentine belt on a 1989 Suburban?
take a breaker bar and socket and put on the bolt on the tensioner wheel, pull on it and loosen the belt. 1 way it tightens and the other way it loosens.How do I losen the serpentine belt on a 1989 Suburban?
look for the idler pullyHow do I losen the serpentine belt on a 1989 Suburban?
15mm bolt on the tensioner , it's the only place the belt makes contact that is not an accessory,ie alt,a/c power steerong pump.Put the 15mm on a breaker bar and push down on the tensioner and the belt will come loose.This is a two hand operation one hand on the breaker bar the other on the beltHow do I losen the serpentine belt on a 1989 Suburban?
look at your belt diagram on the radiator brace. it should show you which pully is the tensioner... make sure you get it and not the idler as the idler doesn't move. the suburban uses a 3/8 drive ratchet to leverage it, i THINK that pushing the handle to the passengers side of the truck will release pressure, slide the belt off, change the pump, put the belt back on.
