Heater grid bolt

[Funcozilla]

Has anyone had the heater grid bolt problem on a 2012-2018 engine?

No but I am very interested as I am now "My own Warranty station".

Everyone talks about it but to my knowledge no first hand experience here.

I started a thread about the bolt a few months ago.

Disconnected the HG years ago, no issues.

 

[Conifer]

Yes, I had it happen. I can try and find some photos.

Here you go, this is my original thread.

Any new updates on the bolt situation ? How do I do a grid delete and not throw a code? I tried on my 04.5 and threw code. I live in SoCal no need for it. I never do the wait to start.

Leave the relay or Solenoid wires connected, follow the wire from the relay/Solenoid back to battery and disconnect at the battery. Don't wait to start....no codes!

If you don’t wait to start does the grid still energize after startup for any length of time till the engine gets to a certain temperature?

Watch for a procedure to fool the system on newer trucks in issue 119 that should be out next month.

Rob I think it still cycles only when idling.

Thanks Learjet and Sag

 

[Learjet]

The cycling after start has never generated a code for me and others have reported the same.

Apparently the way it is monitored is different after start...or it may not be monitored at all after start.

Such a tease.

Went on a MC ride with my SoCal Chrysler Diesel Mechanic yesterday. I asked him how many grid heater nut failures he dealt with, he said NONE.

Well then... no need to talk about it any longer...Since it never happens in So Cal

sounds to me that the failures are possibly from sticky solenoid that ends up fusing together (relay) . I'm still going to do a disconnect.

 

[Cummins12V98]

Wondering if the warmer environment had something to do with no failures in his experience?

I have the up fitter buttons I wonder how much trouble it would be to make one of them activate the grids and only work when button was engaged.

That's what @Learjet was pointing out.
