Thread: 2003 tahoe

    Default 2003 tahoe

    Hello, I am new to this site due to looking at purchasing a 2003 Tahoe with 75,000 miles on it with the 5.3L engine. Any words of advise for a possiable new GM owner? All I have ever had are Ford's. One thing I noticed is that this Tahoe has a "electronic throttle body". Any problems with these like Ford has had? I have never owned anything that didnt have a throttle cable. Any help would be great thanks.

    we hardly ever replace accelerator or tp sensors.

    check both front axle seals for leaking

    make sure ipc needles run smoothly ( ones that are bumpy usually dont have much life left)

    check the tranny lines on the rh side of radiator. if their seaping or leaking it will be right around that area

    if you can get the front tires in the air and check for play in the hubs

    and the notorious bumping in the steering wheel over bumps. usually the I shaft failed due to lack of grease. no biggy there easy fix just jack it off or re-grease it

    those are the most common problems. they are good rigs you'll like it

    What are IPC needles? So the idle air control valve isnt a problem like Ford's? Also, what oil weight do you reccomend? I prefer 10w30.

    ipc is just termonology sorry fellers. instrument panel cluster (ei mph and tach needles)

    no iac valve on them ;)
