2026 Silverado VIN Hack: Look for 8th Digit ‘E’ to Confirm the DFM-Free 5.3L V8 That Ends Lifter Failure
Can you tell me if a new gasser GMC 6.2L Denali or a 2026 5.3L Denali is safe to purchase? I have read a lot about engine failures and just want to be safe. What would you recommend? Plan on purchasing a new truck in the near future.
Thanks for your assistance,
John
Oops I did leave one stat out, pay. High pay for an equipment operator in 1974 was 5$ per hour. Today it’s 25-45$ per hour. Specialties and unions pays are higher. Now I’ll leave you to it.
Were you repairing a previously working AC system? When filling with refrigerant, you need a way to weigh it properly or calculate the amount needed to add to an empty system. Pressures are only relative to temperature and a tool to use for diagnosing. Static pressure means almost nothing in regards to refrigerant charge and will also change with temperature. That said, they're not THAT fickle about exact fill amounts. You have to be considerably over or undercharged for it to impact A/C operation so dramatically.
