    10 RPM clicking mystery

    OK, new serpentine belt installed, the belt I removed had a gm part number so I am assuming it was original. HOWEVER the tapping every 10 revolutions continues. Got out the stethoscope and located the source at some pressure hose at engine driver's side rear . Looks like it goes to the intake...

    10 RPM clicking mystery

    From what I can see from above the serpentine belt looks OK but also appears like it has some miles on it. Taking a road trip next week so heading to NAPA tomorrow for a new belt. Just a note here: I normally do not buy extended warranties but this thing is a rolling appliance so I bit. Had to...

    10 RPM clicking mystery

    At a mere 95,000 miles now, hope for many more. Done Range, trans cooler bypass and K&N catch can. This was my neighbor's car and always admired it.

    Double door lock 18 Yukon

    Have not pulled the door card yet but mechanically disabling the double pull feature sounds like a challenge I can't resist. I know what you are thinking... This must be the same guy that said "hold my beer and watch this".

    Double door lock 18 Yukon

    Thanks for the reply. I did study the manual and my interpretation is the settings would need to automatically unlock the doors upon going into Park. Then one pull would pop the door. I would prefer not unlocking everything so may pull the door cards to mechanically delete this feature. On my...

    Double door lock 18 Yukon

    I am a one year owner of a nice 2018 Yukon and have lots of observations and questions. One thing that bugs me is the front door latch has to be pulled twice to exit. First pull unlocks the door but does not open. Second pull opens. How can I normalize this so the door unlocks AND opens on the...

    AFM Disable Options

    So what you are saying is my GMC AFM messes with the CAN and ECU is just a PIA. Sorry, I just had to do that. Silly me that I thought when I bought the Yukon in April I thought all i would have to do is pull a fuse and that would be it. Duh! Well at least I don't have Auto Start/Stop. On the...

    AFM Disable Options

    Thanks for the reply, Kwing. So there are future implications to using the dongle?? I have a problem with using the OBD port for a nefarious purpose but if it solves the problem....Right now at 84K miles on this recently purchased Yukon I hear a lifter tapping at cold idle. Exhaust note sounds...

    OK, I see a variety of AFM killers on the market from $35 all the way to over $200! What gives? If the all perform the same function, why should I pay big bucks? Thanks, (new guy, 2018 Yukon 5.3 w/84,000 miles.
