    Well Hell Just Froze Over

    I believe GM had trouble with small parts on the lifters or something like that. Not that that led to sludge in GMs, but it did lead to lifter failure. Ford's had issues with oil ports plugging up in the cam phasers. All these issues seem to be mitigated if synthetic oil is used.

    Air bubbles in the coolant reservoir

    That is true. Once I stripped the head of the rockers I was able to confirm there was no Castech logo.

    Well Hell Just Froze Over

    Um... actually mine was. If Dexcool slowly mixes with oil, the buffer additives can cause the oil to sludge. As soon as i fixed my cracked head, my oil did not sludge up anymore. But I know what you are saying.

    Adding an oil cooler

    Ah ha! I've been looking for rear world stories of engine temperature when towing. We were pulling a fully loaded 20' camping trailer up the Coquihalla and I was getting freaked out when the engine temps started to rise about 212F! I guess I could have let it rise more, but if you have ever...

    5.3 vs 6.2 octane

    How heavy is the boat you are towing? My 2002 Tahoe works hard to pull our trailer up hills. Loaded, we had a total loaded weight (truck, trailer, people, cargo etc) of about 10,000 lbs. The engine worked hard and tended to overheat in the summer heat unless I turned off the AC. I know there...

    Which coolant

    I've flushed my system once each year. 1st time to change a thermostat gasket. 2nd time to do the thermostat gasket again because it leaked. (use RTV thermostat seal with the gasket, that solves that problem). 3nd time to change the water pump. 4th time to replace a cracked head. I'm just...

    Tow mirror questions

    This may not be your cup of tea, but these are fantastic mirrors. I can adjust them to see the required 200 feet behind my trailer. Also, it allows me to keep the stock mirror on so I see easily what is beside me, and the tow mirror lets me see what is behind me. Admittedly, the type of...

    At least it seemed to take 19 years for this Chevy to "implode", quite literally.

    Well Hell Just Froze Over

    You're all off the mark on this one. Clearly, everyone knows that Chevy's are overpriced and start falling apart at an early age when compared to Hondas. You should get a Sequoia instead. Fenders don't spontaneously crumple, interiors don't darken with age, and windshiled glass in Hondas...

    Infotainment systems

    GM, I want a #@$!@#% normal radio! I don't want all that extra !@#$%#! :fca5278d: I see what my father is going through with his tablet. These screens do not respond well to elderly skin, they cannot be used with gloves unless you buy special gloves. I know this is the way cars are going...

    You say the seats come out with 2 thumb screws?

    GMTK2xx

    I don't doubt that the later models have things that make them way better. I sure wish I had direct injection, a 6 or 10 speed transmission, DOD (the later version), etc. What I don't want is: -power folding seats. We have them in my wife's Explorer and they're great for her. But for me...

    Does the rear glass still lift separately from the liftgate?

    GMTK2xx

    This raised bed would drive me absolutely nuts. I'm sure it was done to allow a folding 3rd row, but I'd rather just remove the 3rd row seat and have a true flat bed in the back. I think I meant the 2021 Tahoe fixes this. I just saw a picture of a 2020 Tahoe and see the same issue.

    GMTK2xx

    Eventually, my 2002 Tahoe will have to be retired. I was looking at a 2019 for fun and realize how much I appreciate the GMT800 platform. In 2019, and I'm not sure how long GM has been doing this, raised the truck bed to accomodate folding seats. I know the 2020 managed to lower the truck bed...

    Yukon Denali 6.2 towing Travel Trailer

    If you have a weight distributing hitch and have it adjusted correctly, you don't need airbags. In fact, a WDH is a much better and safer option.

    Yukon Denali 6.2 towing Travel Trailer

    The KNP should be the heavy duty one, but it is a lot smaller than any of the Tru-Cool ones. At least, the KNP for 2002 is this one here: https://www.amazon.com/ACDelco-20880895-Equipment-Automatic-Transmission/dp/B0049417FU The regular one appears to be ACDELCO 52497562...

    Yukon Denali 6.2 towing Travel Trailer

    An important question to ask now is what transmission cooler did you replace? Did you get the cold weather bypass? I believe that is required if the vehicle is to be operated in below freezing temperatures. My 2002 Tahoe has the Acdelco heavy duty transmission oil cooler which has the...

    Rear Main Oil Seal

    I stripped threads because I didn't use a torque wrench. If you broke something using a torque wrench, either it was faulty, you accidently set it to ft-lbs for a in-lb spec, or the part was faulty.

    I assume you used a torque wrench for the pan bolts.

    Rear Main Oil Seal

    The problem with distinguishing between the rear main, oil pan seal, or other leaks from the back of the engine, is that the oil pan makes a lip that juts out pas the rear of the block. Anything leaking there, whether it be the rear main, rear cover, oil pressure sensor, camshaft sensor, or...

    Air bubbles in the coolant reservoir

    A couple of years ago I had the same issue. I finally had to accept it had to be leaking internally. I put the pressure tester on and left it on overnight. I saw no drips, smelled no coolant inside, the rear heater core was dry. I finally pulled off the valve cover gaskets and saw this in...

    Oil leak, rear main seal ok? pics

    Torque is critical for the pan bolts. You may wish to check those, especially the rear pan bolts. Also at or on the back of the engine: Rear cover gasket (should have been replaced with the rear main, did they? There is a TSB regarding aluminum blocks, but I think your was before the...
