    2012 Yukon xl 4x4 eating antifreeze?

    yeah, not you, the other guy that seems to be misunderstanding. what's commonly recommended here. in general I've always had good luck with replacing stock plastic radiators with aftermarket aluminum ones in performance cars that need extra cooling, but it seems the ones for these trucks...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    yeah hp can adjust the speedo. it's surprising easy. they have a little utility you put your speedo speed in, GPS speed in and it tells you what to change the number to.

    2012 Yukon xl 4x4 eating antifreeze?

    literally no one recommends aluminum radiators here. there's a DENSO everyone runs. a motor mount that only lasts 80k miles is junk. they should last the life of the car.

    AFM Disable Options

    the oil rabbit hole is deep. every few years I lose a week to it haha. usually come away with if money doesn't matter, just use amsoil, it's easiest and within a few % of the latest and greatest. at work we have some of the Ford v10s in ground power units that really should be and in the past...

    AFM Disable Options

    ahh Facebook group. such a horrible lay out for car stuff but somehow they took over and people refused to use a actual message board any anymore. ghe worst part is as soon as something is answered its basically impossible to find it 6 months later. blah.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I snipped the wire holding my exhaust valve open.. didn't see any change in anything. looking at timing retard for 93 and 87, flashed 2 different timing maps. fuel mileage seems the same, power felt the same. kinda weird, I'd have thought reducing exhaust restriction would have showed up...

    Towing Heavy Transmission Temps

    that's good. mine has small storage, so you gotta be picky about what you need to log. you wouldn't be tuning vve tables off it. but it's super helpful for issues

    What did you do to your OBS GMT400 Tahoe/Yukon Today?

    AFM Disable Options

    using hptuners to disable mine and all the monitors have shown pasted before. I'm a bit curious about this auto sync. does it flash the ecm or do you have to leave it plugged in all the time? what about their bcm mods, same question I guess. can you make changes to the tune? or is it a dongle...

    What did you do to your OBS GMT400 Tahoe/Yukon Today?

    where's the hole in the muffler? I've seen a lot with a small drain hole about the size of the nail to let water out.

    Oil pressure drop after addition of OEM Oil Cooler?

    I believe it's all to the filter, with an internal bypass in the filter if needed and then up and to the oil cooler passageway, with the bypass in the aluminum block able to bypass that when flow right gets high enough and then up into the block. so some sure. you do seem to be seeing more than...

    09 escalade hybrid trans question

    so this is the oil pan drain plug.. it's closer to the front of the truck. this is the tranny pan drain plug.

    09 escalade hybrid trans question

    see that's what makes me wonder.. because the tranny fluid capacity of the 2ml70 hybrid is 14 quarts and believe me, all 14 quarts come flowing out at a high rate when you pull the drain plug, overflowing most people's drain pans. because there's no torque converter to trap floor. the 7 qt...

    Oil pressure drop after addition of OEM Oil Cooler?

    interesting. my 2011 yukon under shows the oil pressure relief valve for the afm stuff that screws inside the oil pan. shows the same type valve under the oil filter bypass valve and oil pressure relief valve. they look the same but different brands listed under each. if I remember right...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I just lubed my stock 160k mile ones. with the energy suspension lube, it's this crazy thick water proof silicone based stuff. they didn't have any crack or anything. Just a little squeaky when cold in the morning. could have been the end links. I did both. ball joints, I have not done these...

    AFM Disable Options

    just a reminder, if you can do without the truck for a few days, you can mail off the ecm and have afm disabled in the tune for 50$ last I checked. it's not as good as buying hptuners, but it is cheaper and better than the dongles to me.

    Oil pressure drop after addition of OEM Oil Cooler?

    there used to be a company that made one for it, well a baffle for the stock pan. but they discontinued it. I had the pan off and was thinking of installing one. emailed them why it was out of stock everywhere. they basically said it didn't work. shame. that's weird about the listing. that...

    Oil pressure drop after addition of OEM Oil Cooler?

    not that's it's relvent here, but as an odd thing. c6 corvette owners manual calls for adding an extra qt of oil over the full on the dipstick amount if it's going to be driven hard. I didn't believe it till I downloaded the owners manual and read it myself. very weird huh. I've done it, and...

    Oil pressure drop after addition of OEM Oil Cooler?

    far as I know there's no adjustments. I was just thinking it might not have it at all. if you're really curious there's a test port on the drivers side of the block in the front. you could test the oil pressure right off the pump and then compare it to the sensor port up tops with a mechanical...

    Rebuilt transmission shifting hard

    the P0700 is trans related, but not the tranny codes. I'm sure a shop scanner would pull them up, they just chose not to show you for some reason. the p codes are just the standardized obd2 codes and then non standard codes take a little better scanner to read. but every module on the truck has...
