#617 of 2238 2500 HD 4x4 postive comments and problems
May 10, 2001 (1:14 pm)
2001 Silverado 2500HD 4x4 Regular Cab, base model, 6.0L, auto trans., 4.10 locking diff., 4300 miles, built East Pontiac, purchased 3/7/01. Overall I am happy with my truck. I purchased it to replace a trusty 4 cyl. Toyata 4x4 that isn’t up to the task of towing. I drove the Chevy from Seattle to LA after its’ first few hundred miles, observing break-in procedure as outlined in owner’s manual. Highway mileage was 15-16 mpg with speeds up to 55mph – then up to 65, once first 500 miles were past. Put many city miles on truck in LA before renting a trailer and picking up my unfinished ’66 Impala from the high desert to bring it back to Seattle. For the drive back to Seattle all of the parts for the ’66 were loaded in the bed and the stripped-down Impala with big-block and trans. installed was trailered. The truck performed very nicely and pulled strongly up the steepest hills of the Grapevine and Siskiyous. Towing mileage was 13-14 mpg, with no speeds over 65mph. Performed first oil change before beginning tow – yielded small amount of shavings on magnetic drain plug. Performed diff. fluid change upon return to Seattle. Used new GM grape-scented gear oil at $28 per quart. Used 2.25 quarts exactly to fill – glad I didn’t follow dealer’s advice – said to use three quarts and see if it needs more.
1) slapping noise from engine at cold start
2) flat spot during acceleration when using light throttle (I tend to drive very conservatively around town), engine sort of bogs down, reminiscent of bad accelerator pump on Rochester 2GC carb.
3) bed rails kind of soft – they dented from me kneeling on them while tightening tarp covering Impala parts. Chevy – not like a rock – like a soft-shelled crab. I guess my knees are kinda knobby.
Anyone else out there with similar complaints? I am especially interested in/worried about the slapping noise. Otherwise the truck is powerful, smooth, and quiet. I am actually happy with the Firestone Steeltex tires – 55lbs. Front, 60lbs. Rear – I have offroaded them in both snow and mud with excellent results and they are fine on the highway – very quiet. I was skeptical about them and took a “wait and see” attitude. I’ll use them until they wear out and then try something more deluxe.

Slap is most likely piston slap when cold startup. Don't think you'll get GM to do anything about unless you have the assistance of the BBB. Good luck.

Er, how serious is "the slap?" Is this the death knell of my engine at such a young age? Are we talking about connecting rod bearings? Or is a piston whacking into the cylinder top? It is definitely coming from within the engine. Your input and ideas are appreciated.

the rod bearings. Seems to be a common thing in these vortec engines. It doesn't seem to cause any problems, but then again the 4.8, 5.3, and 6.0 has been around since '99. That is not long term. I guess it all depends on whether you can live with it or not. Some have pursued buyback, some extended warranties, and others have sold/traded their trucks. Again, it comes back to if you can live with it. There is a couple of sevice bulletins regarding this issue. I'll see if I can dig them up.

Drej. I agree with Hunter48 that your problem may be in the fuel tank. What actually is the problem is the short fuel line between the fuel pump and sender develops a cut or slice. This in turn causes the fuel pump to lose prime and can be a pain to re-prime. The solution is to drop the tank and look very closely at the hose. If I had to do that I would go ahead and replace the fuel pump while I was in there, since Chevy fuel pumps have been known to go out prematurely. You may have already done some damage to the pump, if indeed, you were losing prime and the pump was running dry.
I don't know if I'm correct in this or not, but you may not be able to get codes from the ALDL on your truck. Your truck, being a 95, may have OBDII diagnostics which would not allow you to gather codes without a scanner. Good luck.

#625 of 2238 Headlight switch/warning bell, etc.
May 11, 2001 (12:52 pm)
For Silverado and Sierra: Does anyone know of a way to bypass the automatic headlights, other than depressing the dome light override switch 4 times? Although the system is kind of slick, I would prefer to able to turn on my headlights at will without having to do the override each time. I would also be very happy to get rid of warning tones for lights, seat belt, etc. Is there a reversible fix for this? Thanks, and everyone have a nice weekend.

your questions have been asked since the beginning of the silverado new style. Haven't seen anyone answer it other than no and no.
