Curious what mods can be done without voiding the warrant and which ones are worth getting? Does a cold air intake actually make much difference? How does GM know if you tuned the vehicle?

There are a couple dozen computers in a modern vehicle - it all tattles on you,,,,,,,,,

 

Even the Range V-4 disable would leave a trace - by not having V-4 logs..........

 

Truly you cannot do better than the original air filter - especially compared to oiled units. Of course the sellers of these products will tell you differently.

 

Sometimes it is best to leave things be - I left my 2007.5 Duramax stock and it never let me down in 10 years - and is now serving the next owner just as faithfully.........

Technically no modification voids warranty, the dealer has to prove that your modification led to the warranty being breached. If you install a CAI and your tailgate breaks, you still have the bumper-bumper coverage on this. Now if you install a CAI and your throttle body stops working properly, you will probably be at fault.

I don't know if the dealer HAS to prove anything to anybody. If they even suspect that a mod you did caused a failure, they can deny the repairs. (that's why it pays to have dealers install lifts, etc.)

 

Basically, by modding your truck anywhere other than exterior styling YOU are taking a risk of "voiding" some part of your truck from warranty repairs. The bumper to bumper has a lot of exclusions, have you read it?

 

Now in real life, can you make a lot of changes and still get warranty work done? Yes. Lots of people modify their vehicles in some way, as have I.

 

But be aware that any fiddling with the engine, drive-train and suspension may get you denied in the future. I am aware that if my front suspension components are shot next year, I'll probably have to pay for them due to the large red thing in my picture.

 

One last thing- a mod won't automatically sabotage your entire warranty, just a specific part or set of parts. Again- up to dealers discretion.

well, the factory has incentives to make vehicles as efficient as possible. So if you want to make yours louder and less efficient, MOD AWAY!!!

But I did spend mods money on the Duramax - just not on engine mods. Pin striping - Katzkin - bed cover - etc.......

I remember seeing something in my paper work about aftermarket exhaust voiding your warranty. I'm choosing to go with the dealer install of the borla exhaust as to not void it. I also had the dealer install the GM performance cai (iirc got that and installation for about $330 out the door). I did ask about a catch can and they did tell me that would void the warranty (but they did offer to install it :/). I'll just wait until I'm out of warranty for anything like that,if I even care by then.

Trust me though the dealers are very good at blaming anything on the mods.

 

At least they try to.

 

I only have an Intake and just remove it before I take it in.

 

I'm so good I can take it out and put it back, in just over 9 minutes now ha ha.

      Where is the Ambient Air Temperature Sensor on a 2021 Chevy Suburban?

      By newdude · Posted

      Yea that's pretty normal to be off a few degrees.  Usually 2-4 degrees from say a weather app or thermometer.

      Where is the Ambient Air Temperature Sensor on a 2021 Chevy Suburban?

      By studly · Posted

      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.

      Wow I'm in a pickle. (Broke down truck) and a story.

      That one looks decent for the price   BUT..I want something that also supports OBDI/1.5. A lot of the prosumer-grade scanners don't have legacy support in order to keep costs low. I believe the Autel does if you go higher end with them.   For fun, I reached out to a local Snap-On rep because I was interested in the 2600. $1895 MSRP, says he can do $1595. That's still a lot, but then again, that's not a horrible discount for just asking out of the blue. Could probably do better if I was a regular buying off his truck, but I'm not.   Not sure if I mentioned but I didn't realize with USED scanners from Snap On that you need to make sure a) the serial number isn't flagged as stolen. On the newer ones, SnapOn can remotely disable the device if it's flagged in their system. And, customer service can tell you if it is, if you're thinking about buying used. B) Make sure it's paid off. If the seller still owes money to the truck or if they financed through Snap On, the device can be remotely disabled until the balance is paid. It's less clear if SnapOn will tell you if a balance is still owed; I didn't make it that far with the used model I was considering. I did read that SnapOn has no way of tracking any "truck financing" deals between the SnapOn rep and buyer, only if they financed through corporate. So there's that extra caution needed.   Still waffling on whether I go with a ~$500ish Autel/TopDon or spend bigger money. The value seems to be in the prosumer brands. I'm not giving them enough credit TBH, actual production repair shops use them daily BUT I'm still allergic to certain kinds of underdog products trying to unseat American companies with solid reputations. SnapOn's scanner isn't wholly made in the US, but it is assembled here and they have US support and probably the most proven/ robust legacy support.   Something to think about. Value, or principles? There's a $1k difference.

      Winter Returned

      By Atlas · Posted

      I'm thankful to live where we don't have extreme weather. We might all be blown to smithereens when Mt. Rainier goes, but 80 is warm enough in the summer and I can generally count the number of hard freezes in the winter on one hand. The cars here don't rust and they don't get sun-baked, either.   We have finished off many of our average 52 days of "clear/sunny" weather, though. Sunsets are coming earlier, the nights are a little cooler. It's right around the first week of September when we get our first warning that summer is coming to a close with overcast skies and the start of "hoodie weather" temperatures during the cooler parts of the day. By October, it's usually time to ditch the shorts. By November, it's mostly raining.
