    Radio Issues

    The believe the majority of the radio problems are with apple carplay. When GM finds the problem and sends it to Apply to get resolved Apple just sits on it for 6 months to a year. I have seen the back log of system issues GM has sent to apple for software patches and it is as long as your arm...

    Any Maintenance Techs Here?

    Just my two cents but I can almost guarantee you the second motor failure is because the tech that installed it didnt prelube the engine and for the ones that fail after the picoscope test done for the recall more than like had rod bearing failure the pico test looks for a vibration frequency...

    Motor Oil is Motor Oil

    Alittle off subject but the company that was making the blue ac delco filters was trying to sell out to another company and during the acquisition phase they found out their ceo was embezzling money and they were broke so gm switched filter manufacturers and now the filters could be black or...

    Swooshing sound?

    I know I am late to the party but yeah that valve is the source of the swoosh sound you are hearing. The valve is a back pressure control valve and the actuator that controls it is called an exhaust gas recirculation actuator. GM named them but anyway the valve controls back pressure in the...

    ‘22 ZR2 coolant smell

    Unfortunately alot of times for techs time is money so alot of them dont take the time to find and fix the problem unless it is staring them right in the face. And I wish GM had documented cases for stuff but again I think thats is one of their weakest links is tracking what other dealers...

    Why does ReadyLIFT not recommend AWD while Peak says no problem?

    Looks like Ready lift just wants a way to deny coverage of the supplemental coverage they offer because driving in auto4hi is not excessively hard on the t case unlike the added lift height is to the front axles. The awd shudder is usually caused by burrs or notches that develop on the clutch...

    A/C issues

    Internal valving failure on the a/c compressor. If you have the ability to see the high/low side pressures the high side will be lower than normal and the low side will usually be higher than normal we see 2 to 3 a week in the shop

    ‘22 ZR2 coolant smell

    Look down between your cooling fan and radiator along the edge of the radiator for wet grimy looking spot or have surge tank cap pressure checked both can cause coolant smell

    Motor Locked Up (NEW MOTOR)

    I just finished doing the recall for the 6.2l in a Cadillac and I have done to many of them to count and I can also say some of them I have done came back a few weeks later locked up. It is a messed up deal with GM and these engine but to be honest its not just the 6.2s. I have been replacing...

    What have you done to your Silverado ZR2 this week? 🛠️

    Took a couple of hours this afternoon at work and installed my leveling kit while one of my buddies mounted and balanced tires on my Method wheels then he was even nice enough to do the alignment. Installed my eboards and gator roll up bed cover a few days ago.
