#428 of 2018 2002 GMC Sonoma Problems
Jun 28, 2004 (12:19 pm)
I have the following problems with my 2002 GMC Sonoma w/ ZR7 package.
1) Windows warp out and windows can't be closed. This occurs when it is above 90 degrees or below 20 degrees. I had have it back to the dealer 3 times and they can't seem to duplicate problem.
2) Engine has no upper end power above 3,000 rpm.
I had a 1998 GMC Sonoma (same set up as my 2002) and the 1998 had all kinds of power.Dealer says I just have to live with it. It runs worse than a bad 4 cylinder engine.
3) This 2002 GMC Sonoma is a real gas guzzler. Dealer has installed all updates and replaced air cleaner and the best I can get is 15miles or less on the highway running empty.
Has anybody experienced any problems like this!
#429 of 2018 2001 S-10 ZR-2 W/squeaking noise
Jun 29, 2004 (3:39 am)
heres the jist. Had a squealwhen accelerating and stopping(basically constant). Dealer told me brakes, i told them bull. Changed brakes myself and took old pads in to prove it werent the brakes. dealer then replaces the u-joints like i asked them to do under warranty. i thought it was u-joints. they said they couldnt figure out which one, front or back so they changed both and i looked to make sure they changed them. squeal went away for about and hour. now the squeal is back but you can only hear it with the radio off, windows down and having the sound bounce off of a passing vehicle. im wondering if a bearing is bad on the tailshaft of the transfer case? any ideas?

If you have a flex fuel engine they will burn more fuel, its a compromise between gasoline or alcohol.

Jul 16, 2004 (6:07 pm)
I parked my 2001 S10 today and attempted to restart only 1 hr later. Truck would not start. I jumped truck with another vehicle (started fine). Truck will not start on its own. After starting with another vehicle, odometer lights flicker quickly. When moving the truck, random and sometimes all dash warning lights come on and then all instrument panel power goes off (spedo, tach, all gages, lights, etc). Truck seems to run fine after starting with another vehicle but will not start on its own battery. Battery tests strong and instrument gage shows full power. There is a high pitched wine coming from under the dash when running. truck will not start on its own... I dont understand how this is happening. If the battery is full charge, why does it not start by itself. It will only start by jumping battery to another vehicle.. this doesnt make sense to me!! can anyone help?!?!

Assuming the battery is good because you said it "Tests Good", and assuming the Starter is good because you said it starts good when jumped from another battery, it would only leave a problem in the wiring, cables and connections. A loose connection on a cable could easily cause your problem. Check all cables, tighten all connections.

#434 of 2018 Coolant change on S-10
Sep 01, 2004 (2:26 pm)
Was wondering if any changed the coolant on their S-10. I'm about due to change mine, hitting the five-year mark last month, and though I am WAY under the mileage, thought I would change it just the same. My problem is with the radiator peacock and am wondering how to open it. It's plastic, doesn't have any "ears" on it like the older ones and the head seems to be like the one-way-screw heads, where you can twist it in, but can't twist it out. Can't seem to fit a driver or an extension on/in it. Parts stores don't have a clue or listing for it. Is there a technique or special tool to open the peacock or other method. The shop manual doesn't list anything, just saying it can be opened and to open the peacock on the block, which I have yet to find. Have a 2WD 99 LS reg. cab, short bed, 4.3 V6, 4L60E, ZQ8.

I recently had the coolant changed on my 2000 S10. I had 95,000 km (59,000 miles). I suggest you replace the upper and lower rad hoses, thermostat, and rad cap. GM has had problems with the original rad caps keeping the cooling system pressurized. Good luck!

the "petcock" on the radiator does indeed turn. Just apply a slight bit of force, but be careful. After you turn it counterclockwise a bit, if I remember corectly, it pops out a bit, allowing the coolant to drain.
With regard to the block, I've never seen a petcock installed by the factory. There should be a hex headed pipe plug near the bottom of the block, one on each side.

I always spray mine with penetrating oil before I open or close it, saves from breaking it. Not my idea I picked it up on another site.
