    2012 Yukon Denali 6.2L — Coolant Temps Rising Uphill in Hot Weather

    1. I live in Lebanon, in a fairly small city with multiple steep hills. Inside the city I usually drive around 20 mph, and on some wider roads I can reach 40–45 mph. The steep hills are short but frequent. This is actually the first time I learned about the fans—I only started paying attention...

    Yukon 12 Denali Chinese android unit

    The AMP-CON wire is coming from the Android’s RC connection, right? Did you connect it to a free, unused cable from the CANBUS? In my case, the green wire that fixed the issue was already connected between the CANBUS and the car’s OEM connector (where the head unit’s main connector plugs in)...

    2012 Yukon Denali 6.2L — Coolant Temps Rising Uphill in Hot Weather

    Hi everyone, I have a 2012 Yukon Denali 6.2L with 105k miles. I bought it about 3 years ago at ~94k miles. This summer, when outside temps are above 90°F, my coolant temp will slowly climb past the midpoint (210°F on the gauge) whenever I’m going uphill for 5–10 minutes. If I reduce speed/load...

    Thank you all for the detailed responses and insights—I really appreciate it! Based on your feedback, I’ll try to keep the AutoLevel system if I can find reasonably priced replacement parts locally. The OEM rear shocks from the official GMC repair service are priced at around $1,050 for the...

    I have a 2012 Yukon Denali with blown rear air shocks and a "Service Suspension System" message on the dash. I’m wondering if it’s worth fixing and have some questions about what might be involved. The compressor doesn’t turn on at all. Does this mean I’ll need to replace the compressor along...

    Finally, the issue is fixed. There is an AMP control line that goes out from the RCA cables, which is usually colored blue. It should be connected to a wire on the CAN bus (in my wiring harness, it's colored green). This is my final result: Thank you!

    Yukon 12 Denali Chinese android unit

    Yeah exactly, this has been going for sometime now and they have 0 installation instructions. To be fair they sent me 2 sets of wires stating that it will fix my issue with no luck. I read everywhere that Crutchfield is the best go to regarding head units but unfortunately I can't order to my...

    Yukon 12 Denali Chinese android unit

    Hello everyone! I have a 2012 Yukon Denali with the OEM Bose system, and I recently bought a Chinese Android radio that was advertised as plug-and-play. Most features are working fine, including the OEM camera, door notifications, and automatic switching to the backup camera when in reverse...
