Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

which altenator does my vehicle use? the 105 amp at 11:30 or the 145 amp at 12:00?

that depends on how fancy your Tahoe is, if it is fully loaded with all the accessories then it will use the 145 amp. if you clean off your alternator you will find the amperage stamped on it.

I need to replace the alternator on a 2003 tahoe 4x4 95k and I can remove two of the mounting bolts for the alternator but how do i get the tension off? is there another place I should be looking the two bolts I can remove are simple to get to. Thanks for the help!

There is a belt tensioning pulley (on the opposite side of the engine at least on my 96 and 97). The parts store where you purchased the alternator should have the tool that let's you move this easily.

I am trying to replace the alternator but I can't locate the belt tensioner. Where is it on this vehicle?

Yesterday I was driving my Tahoe and it cut off and would not start until we jumped it off. When it did start back up the battery meter showed that my battery was fully charged. The battery is two months old, the starter has been replaced a year ago, and the alternator is about 3 years old. I do not know what is causing this.

did you load test the battery. do you know what the voltage output of the alternator is

How do i remove my alternator?

Hi Anthony,

First you will need to disconnect the Negative Battery Terminal. Then remove the Belt. You will then need to remove components as needed to gain access to the Alternator. Then remove all electrical connections on the Alternator. Then remove all bolts and nut holding the alternator in place. You may need to remove the brackets holding the alternator to remove it.

.

Remove the wires as described. There are just two long bolts holding the alternator. Remove them and CAREFULLY pry the alternator out. I know - it's in there tight - so pry on oit easy. It is sometimes usefull to have the new part ready to install so you can see where mounting bolts are....On your alternator there is NO belt tension adjustment to be done with the alternator.
