SOURCE: location of fuse box/panel for 2004 yukon denali xl

There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.

The ohter is under the dash and above the pedals, this one is much tougher to access.

Your Owner's Manual should tell you where the fuses are that you need to access.

SOURCE: how do i replace my water pump on a gmc yukon xl

First you will need to remove your tension belt from all your pullies. This is usually done finding a pully that provides tension to and takes away from the belt. HINT: It will be one that doesnt have abunch of mechanical part atached behind it. After removing hte belt in the center of the motor about mid ways up there is a pully that has a hose runing behind it. The other end of the hose goes to the radiator. Well where this plugs into the motor is the waterpump. you more than likely will need to remove the pully from the pump. Above is a picture of your pump with the pulley removed. The four bolts in the center are how you disconnect the pulley and the four on the side of the pump are how you disconnect from the motor. Make sure when you get done and all back together to look around the new pump for leaks.


Below is a picture of the pully of and on.
