Question:
My truck is a 2023 F350 4x4 with 6.7 HO. Grok tells me this heater will fit on the rear block on the drivers side. Will it fit there?

Hey Dale. There's not enough flat space on your F-350's engine block for the Kat's Heaters Handi-Heat Magnum Magnetic Heater item # KH1190. This heater measures 5" x 4-1/4" and it needs a flat surface at least that large to attach to. Since your oil pan is aluminum that's not going to be a suitable mounting space either.
As an alternative, I recommend the Kat's Heaters Oil or Transmission Pan Heating Pad item # KH24500. This is a 500 watt heating pad that you'll be able to attach directly to your F-350's oil pan. It uses an extremely strong adhesive to attach so you won't have to worry about magnets. It's also powered by a standard 120v outlet.
Does your F-350 have the factory-installed block heater element?

Thanks for the reply, this again proves that AI is not always correct. No, I cannot believe my F350 does not have the block heater installed, especially considering we're in Northern Wisconsin. I was hoping to use a magnetic heater since it's too cold now to apply an adhesive, -4 F now at noon. Any other alternative?
