I just replaced the ambient air temperature sensor. Easy as pie. I simply had to remove about 10-12 clips on the plastic cover over the radiator and remove two T-10 torx screws on the hood release lever to liberate the cover (Amazingly, none of the clips broke. All came out and went back in with zero problems). Once the cover was removed, the temp sensor is easily accessible. The sensor cable snakes through a few guides and can be pulled out for even easier access to the sensor. I was able to work the sensor out of the mounting hole. There is a red sliding catch on the plug that must be pulled back to disconnect the cable. The plug was quite tight. I had to use a screwdriver to pry it out. I plugged in the new sensor ($6.45 from RockAuto), snapped it into the mounting hole and re-snaked the cable. I put the radiator cover back on and reattached the lever arm to the hood release. All done! I started up my Suburban. The temperature read 82 °F. Other thermometers at my house read 80 °F. Close enough. It might be reading high as my vehicle was sitting in the sun.

Yes! That graphic helped me locate it perfectly.

Where is the Ambient Air Temperature Sensor on a 2021 Chevy Suburban? How do you access it? I believe mine is going bad.

My 2021 Suburban had the cherry red tintcoat which looks like what you have. My paint is still in great shape. People ask me how I make is shine so much. I do wax it several times per year.

Every once in a while, I hear a sloshing sound but it doesn't seem to be a problem otherwise.

I'm looking for longevity. V-8 Suburbans statistically last longer than V-6 Fords.

Ford doesn't make any SUV's with a V-8.

When you're in part-time 4WD on a hard, dry surface, the vehicle is going to buck when turning as the front wheels are fighting the back wheels as they both want to rotate at different speeds. All part-time 4WD vehicles will do this. And this is hard on the drive train. That's why they call it "part-time." You don't want to leave it in this mode for regular driving. The AUTO mode solves this problem by running in 2WD and only engaging 4WD when a loss of traction is detected.

Never forget that Suburbans are sought simply for their towing capabilities. The max towing package will add resale value to any Suburban. If you have to pay more (and/or shop longer) for a Suburban with max towing, it will bring back more money in the future if/when you choose to sell it.

Is there a reasonable place where I can tap some power in the overhead console for a dash cam?

Is it stolen?
