    Grid Heater Delete?

    I have a 2018 RAM with 20k miles.

    How common is the grid heater bolt issue?

    Should I be concerned?

    I did the wiggle test, and there was no issue there.

    Also, if I remove it, will it throw a code?

    Remove it and opt for the Glacier Diesel unit.

    It pulls the same power as the oem.

    It's a hit-and-miss on specific rigs.

    In my head, I'll take the reassurance that the bolt will never drop into the cylinder and delete it.

    Most tuners will automatically turn off a code to be generated if you delete it.

    If you live in a really cold climate, seek out the relocation intake horns by banks.

    Plus, with it deleted, you won't be pulling amps on initial startups, which your charging system will enjoy.

    I agree with the posts above.

    It’s more for peace of mind to eliminate the possibility of catastrophic engine damage.

    If you live in a cold climate, install a good aftermarket grid heater like the Glacier Diesel MegaFlow.

    If you live in a warm climate, you don’t need the grid heater, but you can install an intake horn with a small screw in the heater; this will satisfy the PCM logic and avoid any grid heater-related trouble codes.

    The other option is to have the grid heater trouble code programmed out.

    I deleted mine a month ago, so don't let the grid heater cycle when I start it.

    I live up north but I don't drive the truck in the winter month but sense we didn't have much of a winter this year I have been driving it and I haven't got any check engine lights.
