    Have a 2000 freightliner century class with the isx Cummins. I've been having issues with it running hotter then it should be. I'm hoping some one can give me some advice on where to look next. With the fan on auto it will run upwards of 230f or more. Hot enough that the warning light will come on. If I run with the fan on manual, it will get up to 215 max. Which I think is a normal temp(correct me if I'm wrong).

    Truck info,
    Farm truck pulling tridem grain trailer mainly. Not long distances, so a lot of shifting up and down. loaded gvw is 47,500kgs(104,000lbs).

    What I've tried,
    Replaced coolant filter(several times), thermostats, water pump.
    Done coolant system flushes, and cleaned the rad. The rad is clean and fresh coolant in the truck with proper mix.

    I'm not sure where else to look. any help, will be much appreciated!

    Try replacing the coolant temp sensor. Since the warning light is also coming on, the gauge is reading correcting, but the sensor could be measuring falsely.

    215 is normal when climbing a hill, but typical temps cruising on flat ground are 170-190. If 215 is normal, then there is a problem.

    You can pull the grill out and unbolt the charge air cooler, then look how much dirt has stuck to the inside of it and rad. then clean it out good.

    Mike379L,

    I agree with all the suggestions given.
    If you don't have to pull any long hills you will likely be able to get by running with the fan on on overide until the weather cools off.

    When you say the rad is clean do you mean it was done by a Rad shop or with a garden hose?
    If the other suggestions don't fix your problem and its already been to the the Rad shop you will likely have to replace the rad core.

    I had a lot of problems with my T600 rad cores using the green antifreeze.
    Rad shop cleaning didn't last very long.
    When I switched to long life antifreeze the rad cores lasted a lot longer.

    thanks for the suggestions everyone! Im going to look further into how clean the rad is. From what I can see it is clean, but maybe I haven't done a good enough job on that. Also going to change the temp sensor. fairly cheap and easy thing to try. Thanks again!

    Did you ever figure out what the problem was with your truck? I have a Volvo with a ISX with the same issue.
