    I have a 13 Silverado 4.8. When my truck idles for a few minutes either in drive or park with the heater on the temp starts to rise. Its never over heated. Once I start moving or I hit the AC button and the other fan kicks on the temp will do down. Never climbs past the half way mark any other time.
    It's done this since I bought it new, I don't know if this is a normal thing or if I need to get it fixed. Could it be the second fan doesn't kick on with the heater on?

    The highest I've ever seen it get was 235-240.

    That sounds a bit too hot. Are you sure the regular fan is working? Is there anything blocking the radiator?

    Pretty sure the radiator is good. I can idle all day during the summer always stays at 210.
    Just during the winter it does this.
    If I had to guess it's a fan issue of some sort just didn't know if anybody else had this issue. I should have gotten it fixed when I had my warranty

    Your fans should start to kick on at 220, I would hook a scan tool up and check that the temperature your gauges are showing is true to the actual temperature the scan tool reads

    Don't kick yourself for not taking it to the stealership, they most likely would of gave you the run around or would of said that's normal running temp and there is only a issue if it goes over 260 since that's what the manual says.

    Yeah I hate taking it up there for something that's not obviously broken.
