#41 of 1492 6.5L Diesel advice requested by eric99504 Jan 09, 2001 (11:24 pm)
I am considering a 1998 K3500 Crew Cab with the Diesel engine. It's the same engine they put in the Hummer, or HMMWV. I have researched this power plant and have not found anybody ready to "sing its praises". Many say the 1998 K3500 is a fine truck, but nobody raves about this engine like they do about the new Duramax, or the Power Stroke or Cummins.     Any kind words, or words of warning would be appreciated. I have read many references to the injector pumps failing, and some valve/compression issues. I understand that it has a lot of torque, but only 190 horsepower. I am concerned that while it may get up and pull my trailer (high torque) it may not get there very quickly (low horsepower).   Thanks for any help you can provide,   Eric B, Anchorage, Alaska

While you're waiting for a response here, you should also try asking (copy/paste) your question in this discussion: Chevy Silverado/GMC Sierra (1988 - 1998). Good luck.   Pocahontas Host Pickups Message Board
#43 of 1492 ZRT7 - 2K Sierra pulling to the right! by shiftless Jan 10, 2001 (6:17 pm)
Several problems your service shop should be aware of:    First is the front end alignment specs from the factory were in error. (New specs get both wheels going in the right direction).   Second is a defective steering shaft. Original shaft causes a rattle after 9K miles or so. (Replacement shaft is a tighter fit).   Third is probably your problem pulling to the right. A defective steering box. (The power assist valves are not balanced & cause a pulling usually to the right).   Factory warranty should cover all costs to you.

PS: For the front end alignment error, they replaced both of my front tires with only 7000 miles with no sign of wear.
#45 of 1492 Pulls to the right by erikheiker Jan 10, 2001 (6:43 pm)
Several questions for Shiftless. Is this a problem on the 2WD or 4WD? Have these problems been corrected for 2001 models? Are you also Lazy?   Thanks,   Erik

Answer 1. If you read ZRT7 question #35 you would know my answer was directed to him for a 2K Sierra, 1500, 4W/D Z71.   Answer 2. My experience is with a 2K Sierra not a 2001. The factory is aware of the problems I mentioned to a point of issuing a Tech. Bulletin on each of them. I don't know about the 2001.   Answer 3. Yes I am lazy.   For all of you regulars, I have been a steady reader of this forum since March 1999 and I appreciate all of the good information you have passed on to many of us who have stayed on the sidelines. For example, my first direction was to buy another 2 W/D to replace my 21 year old 1978 Sierra. I live in NH & driving in the snow for these 21 years was never a problem with 2 W/D. However, because of the drive line vibrations you covered primarily on 2 W/D, I decided to get a 4 W/D instead. You guys saved me a lot of heartache. Just for the record this is what I have:   2K GMC Sierra, SLE, 4 W/D, 1500, Short Bed, Regular Cab 5.3 V8 3.73 Locking Differential Plow Prep Package Trailer Package Z71 Package Polished Aluminum Wheels (Good For Resisting Corrosion From Road Salt) Active Transfer Case Bucket Seats Sliding Rear Window (No Leaks) P265-75R-16 WOL Block Heater Color: Toreador Red W/Pewter (Sorry about that Ryan) ARE - Hard Tonneau Cover W/Nomadic "Glider" Roof Rack   8000 Miles And Enjoying Every Trip (Smooth, Quiet & Strong)   Ed
#47 of 1492 Rear door wind noise by jlflemmons Jan 12, 2001 (9:21 am)
I know I read about this somewhere in the forums, but is there a TSB out for the 4door Ext cab rear window wind noise? I drive a 2k 2500 and at about 3000 miles the drivers side rear door window made a 'pop' and now it has wind noise like a hurricane. If I pull in on the latch firmly, I hear a pop inside the trim, but as soon as I get back up to highway speed, "pop" and the noise is back. The window stays latched, just not very tight. Before I take this in for warranty, I want to be armed with any data on a TSB.   Thanks!   Jim

Jim, On the first visit back to the dealer for wind noise, they replaced the rear window latches per the most recent TSB they had at the time. That did nothing to help the problem. Yesterday they replaced the entire window and frame on both sides as per a new TSB. That seems to have done as much as the latch replacement did ! Don't know what they will try next, but the local GM re is scheduled to drive my 2000 Sierra so he can feel the torgue converter lock up at 38 miles and hour. Perhaps he will notice the wind noise while he is downshifting my automatic transmission to get it to go to a lower gear !! I would have your dealer at least replace the latches, it might help your problem.                               Brad
#49 of 1492 When test driving for the converter lockup, best to by obyone Jan 13, 2001 (1:54 pm)
take the truck up to 50-55 then back down to 38-40. That way you're insured that OD is engaged.
#50 of 1492 Latest TSB on rear quarter windows by obyone Jan 13, 2001 (1:55 pm)
Seems GM has gone 50/50 on mine as my drivers side is fine but the passenger still leaks air.
