2005 CHEVROLET SILVERADO 3500 Engine And Engine Cooling Problems

TL*THE CONTACT OWNS A 2005 CHEVROLET SILVERADO 3500. WHILE DRIVING 5 MPH, THE POWER STEERING FAILS. THE FAILURE BECOMES MORE SEVERE AFTER THE VEHICLE HAS BEEN RUNNING FOR SOME TIME OR DURING WARM WEATHER. THE VEHICLE WAS TAKEN TO THE DEALER OVER TEN TIMES AND THEY REPLACED THE POWER STEERING PUMP AND STEERING GEAR BOX. THE CONTACT WAS FINALLY INFORMED THAT THE TIRES HAD INSUFFICIENT AIR. THE FAILURES HAVE NOT BEEN CORRECTED. THE ENGINE ALSO OVERHEATS WHEN DRIVING UPHILL, PULLING A TRAILER, AND DURING WARM WEATHER. THE DEALER REPLACED THE COOLING FAN AND THE INTAKE SYSTEM. THE CONTACT STATED THAT THERE WAS A TSB (1980030) REGARDING THE ENGINE OVERHEATING. THE CURRENT MILEAGE WAS 21,500 AND FAILURE MILEAGE WAS 1,613. UPDATED 3/4/08 *CN UPDATED 03/04/08 *TR

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)
