    Default '05 Lly Tsb 1850306

    Hey,
    I just bought my truck and the temp runs at 210 under both unloaded and towing, so I took it to the dealer and told them about 1850306, they "tested" the engine and said it qualified for the TSB, so they ordered parts and installed a '06 air cleaner, which appears to have a larger feed tube. Anyway, the new tube wasn't long enough to reach the input to the engine, so the tech hacked off a 5" piece of the old tube and used a hose clamp. Now I maybe be picky, but if a factory modification doesn't fit, I call the factory, not get out my trusty hacksaw. I have seen the temps go down to 190, but then go back up to 210 and then back down. but, I think the reduction in tube size has defeated the whole purpose. Anyone else have this mod done with the same results? Any advice?

    Default 208F Constant Engine Temp

    My 05 LLY runs a rock solid temp of 208F, whether towing over mountains or unloaded on the interstate. I don't think my truck has ever run a much different engine temp.

    BTW, the cooling fan does come ON, for a short period, during the steeper mountain pulls, though. I didn't feel 208F was a problem.
