Thread: Grid Heater Troubles?

    Grid Heater Troubles?

    Hi all.

    I have a check engine light on my 2013 that came on the other day and the code was P2609 intake air heater.

    So I looked at the relay and it looked good then I followed the power wire going from relay to the heater element and noticed the stud was loose and they call it the Cummins grid heater killer bolt.

    So I am wondering if I should do the delete or get a new grid heater element?

    Please help LOL.

    It's definitely up to you but if you don't live in an extremely cold climate then i would just remove it. I would utilize the Glacier Diesel Power grid heater delete.

    If you would like to have some type of grid heater they have one that you can install easily.

    Thanks; yeah, I live in Missouri, so it’s not too bad here, and I am just worried that that bolt will break off and get down on one of the cylinders.

    Just delete it.

    If you need a grid heater go with the inline one that installs in the post-filter intake tubing.

    My 2013 2609 CEL came on.

    Checked the grid heater bolt and it was loose. I shut the truck down and removed it that day. 127K miles on the truck.

    If you decide to keep it stock and replace with a new Cummins heater make sure you check the Torque on the inner bolt before installed.

    The heater grid maintenance is required i think every 60.000 miles anyway for cleaning. Just replace it.

    This took 2 days to get to me. I live in the North Pole it helps LOL.

    Sorry to tag on to this post but I am in the same boat on my 2013 2500. Intermittent p2609 code and loose grid heater terminal.

    I ordered a new grid heater but want to make sure this doesn’t happen again. Is checking the torque on the inside bolt sufficient?

    I was thinking about tig welding the nut to the bolt so it definitely won’t come off.

    Just an FYI. I love in Communist California so I don’t want to delete it and I need to pass a smog check immediately.

    Well the way i looked it this issue is there are 10"s of 1000's of stock 6'7 trucks of every year out there that have the factory grid heater still and most likely even some that recommend delete or aftermarket /But they may still have the factory grid still themselves . Mine took 127.000 miles to fail . I purchased our truck 2nd hand with said miles the day after we purchased the 2609 came on thought it was a mirror replacement and temp sensor that was 2609 . Nope damn heater bolt was loose . turned the truck off and pulled it immediately and replaced . Now this truck will only see about 2500 miles a year now and is in garage. it will never see additional 127.000 miles again LOL .. Works great and a tach weld would be a great idea to keep currant solid to keep it from arching . Good thing was @ 127K miles the intake was not as bad as i have seen . very little crap inside grid . It will most likely Rust out before i have to replace grid heater again . Now if we could just get the Goberment here to stop killing our fish in our rivers and spreading Iodine all over the roads maybe we can save the world with our DEF fluid such bull$hit hypocrisy

    The nut isn't coming off the stud, the stud is melting in half. When it ends up busting completely off it drops into the intake manifold and kaboom, big problems.

    I check mine regularly to make sure there’s no play. When I get some extra cash i’m getting rid of it and going with an aftermarket horn and the gdp heater. It’s not likely to happen but it is happening enough for a tsb to have been issued.

    Oh. I was under the impression that the nut came loose and caused an arc that melted the bolt but I may be wrong.

    I think it has more to do with the current passing through that little stud. Check this video out for some examples of bad ones.
