    At a loss with electrical/mech problems - 2015 Tahoe LTZ

    I wouldn't engage the parts cannon quite yet my suggestions - test the current state of the battery, it is fully charged or is it discharged (if isn't low, either it isn't being charged or some draw is pulling it down) - test the alternator, is it outputting as intended my guess is that that...

    Oil pickup tube o-ring replacement

    I have a 2007 Tahoe (4x4) with the 5.3; it's on tracks, use it on the lakes in the winter. It started having low oil pressure, when hot, at idle. Verified it wasn't the sensor via manual gauge. I left the oil pan on (4x4 so it's a pain to drop it). Instead, I went through the front cover...

    2025 with problems

    Wife has a '21 with 48k on it. I spent the last week in it on a large road trip. I noticed that 'at times' the oil pressure was below 30psi at highway speeds, at other times it was running a fair a bit higher. I don't recall this ever being a thing. Also, after it had been running for a...

    Early oil change opinions

    follow the dash; unless changing it early makes you feal better, it's your money how I got my opinion, Find a large fleet, find the Operations Director, ask them how they handle their oil changes for the 100k so vehicles they have. I have yet to find one that is doing early oil changes. The...

    GMC v. Chevrolet - Does Brand Matter?

    This part is 100% dealer dependent and nothing to-do with the brands I've spent time working in both Chevy and GMC dealers; they are the same, the difference is how they are operated.

    3.0 vs 6.2

    so... she already doesn't like the performance of the 5.3 and your thinking 3.0 going from a TRX to a 3.0 is a significant step down in regard to pep my daily is an RHO, wife's daily is a Denali xl with the 3.0; night and day difference when I switch between them she isn't like to like the 3.0

    3.0 vs 6.2

    We have both a 3.0 and a 6.2 in Denali xl's 3.0 gets better mileage, that's the only benefit, if the mileage wasn't so much better no reason to buy one 6.2 has more power (more noticeable at interstate speeds) and is quieter (mostly noticeable at idle) the gm 3.0 is way better with short trips...

    O.E. Tires

    Thoughts on purchasing a higher-mileage Duramax?

    baby diesels out of warranty aren't for the faint of heart I owned an ecoDiesel from new for 103k miles which I just traded a couple weeks ago. Wife's daily is a 3.0 duramax. Both have had thousands of dollars of warranty work. All these posts about 300k 3.0 diesel engines; after owning a...

    A few newbie diesel questions

    Regarding startup and cooldown, treat it like any other engine. At first startup (say first 5 min), be reasonable as it's coming up to operating temperature. If it's really cold (say -10F or below) I let them idle for a minute or 2 before moving. I don't use any additives, fill up at high...

    Complaints on ‘25 Tahoe?

    to void a warranty the 'mod' needs to cause harm for example, add a supercharger then the transmission started slipping, they argument will be that the added power caused the slippage disabling start/stop isn't causing harm, i.e. the warranty isn't going to be voided
