    Which alternator for 2013 Yukon Denali XL? ACDelco 145 Amp?

    I can't figure out what Amps my old one had. It's not charging. At idle, it barely makes it to 13V. My other Denali at idles generates almost 15V so I know something is wrong. The vehicle has 180K miles. I get all the classic signs of a failed alternator. I am looking at this ACDelco on Amazon...

    2013 Yukon Denali XL gas tank question

    So I know the gas tank is 31 gallons. Yet when it's flashing you are low on fuel, I can only add something like 21 gallons, like yesterday, or 26 gallons if it's completely empty, on zero. Either the sending unit is not right, or .. what? If I added 21 gallons, why it was saying you are low...

    AC Delco or Moog front end rebuild kit for 2013 Yukon

    2013 Yukon XL Denali, 6.2L AWD Nothing impressive on RockAuto, the best kit they have is MevoTech 8-piece and based on the reports, it's mediocre. Is there a similar kit based on Moog parts or OEM AC Delco? The rearch revealed nothing on Ebay, Amazon, this forum, etc. I do not want to buy all...

    2013 Yukon XL Denali - introduction and questions

    Finally said good bye to the 2008 Tahoe with 5.3L. It stubbornly would not quit, after 267K miles, just kept ticking. Without major repairs. Maybe because I disabled the AFM 100K miles ago. Anyway. Just got this and what a beast. 2013 Denali XL. Specifically wanted these specs. One-owner...

    Which tuner to disable AFM?

    I've had good luck with DiabloSport but can't get mine to go beyond the boot screen, it does not go into the configure mode. Just hangs.

    AC does not turn on

    2008 Tahoe with 253K miles AC rarely turns on, it usually kind of works only when driving on the highway and even then erratically. Never when parked. I replaced the resistor that's located directly under the glove box to no avail. When parked, it seems to work a bit from the rear vents, not...

    2008 Tahoe with 240K miles The fuel pump assembly has leaked for years, at the top where it apparently rusted. It drips when the engine is running. Looking on rockauto and can't figure out which part number to get, or are there alternatives, or just easier to get something at Autozone or...

    Removed rear seats

    2008 LT I removed the rear (2nd row) seats. Should have done this years ago, as I never have passengers and it freed up lots of space. The 2nd row never folded really well into a flat surface so they were more of an aggravation than anything.
