Replying to: lemoncrd (Sep 03, 2009 3:43 pm) Several people reported a bug in the processing of the engine temperature displayed on the console. In case the engine really over heats, you will be notified by the engine malfunction indicator and the injection system will turn itself off. Try to use the engine above 2000 rpm when you torque it; this will improve horsepower + cooling + life of the torque converter. I also live in a mountain area and I know diesels need to breathe to provide the extra effort. I have close to 100,000 miles and this engine performs better than it did when I got it new For info: During 4 hours at a steady 80 mph with 3 passengers plus luggage and 90 degrees Fahrenheit (in the shade), the temperature indicator needle did not pass over the mid temperature line. For "lightnin3": my tire pressure was 39psi Replies to this message: lemoncrd (Sep 06, 2009 7:30 am)

Replying to: caribou1 (Sep 04, 2009 4:15 am) Thanks, it makes me feel better to learn that there is a malfunction indicator and shutoff system. I have a friend with the same vehicle and he said there was a Technical Service Bulletin (TSB) out and they fixed his, but he couldn't remeber the details. I asked the dealer and they said "huh?". I did some looking on another forum, and they show TSB 08-043-05 as reprogramming the software so the gauge shows the correct temperature. It sounds fishy to me, because of the abrupt runup from straight up to far right on the gauge and it only happens when towing uphill. I'll go back to the dealer with the TSB number and see what I get.
