Remove alternator chevy tahoe 2003. Need to remove alternator on chevy 2003 tahoe so it can be tested. Found the two bolts that fix alternator to the mounting, but after removing them, it won't budge. Belt tension may be holding it in place.

Hi, the 2003 Chevy Tahoe utilzes a non servicable timing chain, and does not have a timing belt. Thanks...Coop

Removal & Installation

1. Remove the driver's side knee bolster.
   

2. Push down on the small tab and disengage the electrical connector.
   

3. Remove the pedal bolts and remove the pedal and sensor assembly.
   

4. Installation is the reverse of removal.
   hope this helps

take it to AutoZone... they will do a charging system inspection free of charge!

2004 chevy tahoe 4x4 had the same problem wont turn right at idle - like no power steering , has hydoboost brake steering system , did test and found steering box bad , removed box and remove the top cover on box 4 bolts at hydralic cover and removed and found spool valve has 4 seals 1 outer was blown i replaced box with reman from advance auto about $200.00 and flushed system , drove great problem solved .

The thermostat is under the alternator.

If you have a memory saver to keep radio & PCM settings, install it now.

Remove negative battery cable from battery. Remove positive cable from alternator and disconnect harness plug from alternator.

Remove accessory belt noting how it is installed for later reinstallation.

Remove engine lifting hook in front of alternator.

Remove (3) bolts holding alternator on.

Drain coolant from radiator (may want to start this as first step as it takes a while). Loosen pressure cap to aid in system draindown.

Remove radiator hose from thermostat housing.

Remove two bolts from housing and remove from engine.

Reinstall is reverse keeping in mind the following:

Cleanliness counts where thermostat housing seals to engine.
Thermostat spring should point into engine.
If the thermostat has a bleed port, it should go to the 12 o'clock position (up).

I have had the EXACT same problem with my 03 Chevy Tahoe!!! I have yet to find out the solution!? I cleaned all my grounds and changed my rear speed sensor along with bench tested my alternator! Have you found the problem? I would be very grateful if you could hit me back with an answer!! Thanks

I just about had a meltdown when I found that the alternator will not fit past the body work. However there is a simple solution. Remove the passenger side headlight. To do this there is a plastic lever you slide up , this releases the headlight. Remove 3 torx head screws holding in the headlight cup and the alternator will come out easily through the headlight hole.

Knock sensor can be found on top of the engine block, there are two you ´d have to remove the intake manifold to get to them,

Some of the 03 Tahoe's have an issue with the Crankshaft position sensor that causes it to stall or not crank at all. Have someone check the Crankshaft position sensor.

1st disconnect the battery! Use a tensioner pulley release tool to get the serp. belt off, then remove the wiring harness to the alternator, then pull the top short bolt out, then remove the long pivot bolt at the bottom of the alt.
