Does the 99 5.7L Vortec have a cold-start injector to help get the engine going when it's been sitting overnight or for days and days? My older car has one and I'm having a hard time starting my Yukon after it's been sitting for a few days, so I'm just wondering what is supposed to give the engine that little bit of extra fuel when you're starting it cold?

- 2026 6.6 L5P oil cooler leaking oil at 4,000 miles
  
  By Brendan C · Posted 2 hours ago
  
  New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?
- Seems to be Missing a lot of Updates

  So, GMCustomerService: Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above. So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s). Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.
