Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2005 Chevrolet Silverado 2500hd with the 6.6 liter duramax engine overheated when pulling my 25 feet travel trailer. Found this to be a hazard that GM was aware and was not doing anything to correct the problem.

I believe my 2005 Chevrolet Silverado 3500, duramax/allison was equiped with under designed cooling systems; both transmission and engine. On slow mountain type roads I can run my unloaded truck into near overheat conditions. I believe these issues may be common to other '04.5 and '05 lly GM and Chevrolet trucks like mine and GM has not provided it's dealer network with solutions to remedy the problem (most of them are simple, that the other 2 majors seem to understand: Air flow control throught the cooling stack and cold air to the intake)

problem #1

Silverado 3500 4WD 8-cyl Diesel

  • Automatic transmission
  • 3,500 miles
Truck has 11000 miles, been in the shop 5 times for over heating while towing. GM technician line has a case # on file, and told the technician who relayed the information to myself that they were aware of the problem but at this time have no fix. I call bs because the 06 models have revised cooling systems and a larger turbo charger. My belief is the fix is to much $$ and they will only take care of the few people that tow and have issues. I have notice a lot of information on the net about 04.5 and 05 lly duramax truck that tow over 10000 have this issue. The major down side is the trucks inability to maintain the speed limit due to the 234* plus water temperature and the power loss formed a cooling fan that runs no stop when towing. I have made the same pull with my 2001 Chevrolet duramax truck and have not had issues with impeding traffic flow.
