    5.3 Guys, opinion on oil change intervals

    I have an 07 Tahoe with 317,000 on it and I put 295,000 of that on and a 2017 with 102,000 and do the changes myself. The 2007 burns some oil these days, however, leaks more than it burns (for another thread). I use Valvoline in both and change at 3,500. However, I think most all oils on the...

    Sealing up the oil cooler block-off plate once and for all?

    Hey Dave, The OEM part warped on my 07 and replaced with the plate Ron linked to. It's been on over 2 years and no leaks. Tim

    Considering buying a 2017 Tahoe Lt--need input from 4th gen owners

    I have a 2017 LT 5.3 with 100k (I put 23k on it). I concur with the rest of the folks, ride and handling is very good and especially on long trips. I did have to have the trans rebuilt at around 88K, the torque converters on these trans are not good as they shed metal. Also, the trans...

    Low oil pressure

    @Tjudd, I had to replace the timing chain, tensioner, gears, oil pump and pan gasket/oil pick-up ring on my 07 Tahoe. On the initial start-up I had an issue with the lower oil pressure than normal. As it turned out, the Purolator oil filter I used did not pressurizing properly. I replaced with...

    2017 Radiator Failure

    Update - I went ahead and tore this down. As a reference point, there is not a trans cooler in the radiator of this vehicle, the trans cooler lines run into the AC condenser and is in the upper half of the condenser. Thus the puzzling question of how glycol could get into the trans fluid. The...

    2016 Yukon Denali - Died over weekend

    Because it's completely dead, it sounds like the battery may have had a plate collapse and shorted itself internally so to speak. As other have stated, battery replacement is pretty easy. You can pick up a decent battery at Wal-mart or Menards as well they have decent warranty and I believe the...

    2017 Radiator Failure

    Dave, when you say 'air-to-oil cooler' are you referring to the cooler in the upper half of the AC condenser? I did not see an external cooler in front of the AC condenser. Thanks, Tim

    2017 Radiator Failure

    Hey Guys, I haven't had time to replacing radiator yet but I have a question, if I recall when I changed the AC condensor the trans lines input into it. So, is the trans cooler in the condenser or the radiator? If its in the condenser, how could coolant get into the trans fluid?

    2017 Tahoe - AC went out, suggestions for what shop? (dealer or independent)

    As everyone on this thread has stated, there is a high probability its the condenser. I have direct experience on my 2017, mine went out after 80k. Took it to our local dealer and they were willing to absorb the cost of the condenser but wanted to charge me for labor which was material. We went...

    Camshaft Position Sensor / P0013

    Oldchev, I'll second what Mattbta explained. I have encountered the 'run on' issue when I replaced the cam sensor with an aftermarket. Albeit it was on a 07 5.3L. I ended up taking it out and replacing with ACDelco, problem stopped.

    Electrolysis - Radiator

    I am going to swap out the radiator in my 2017 due to coolant in the trans fluid. However, before doing so, I wanted to check and make sure I didn't have a case of electrolysis going on. So I looked up the method in which to check, it stated to remove the radiator cap to access the fluid...

    2017 Radiator Failure

    Interesting update - the trans shop called me and wanted me to bring it in so they could look at the a sample of the fluid. Which I did and they don't believe there is coolant in the fluid because the fluid is bright red and there is no milky look whatsoever. It could be the amount is so slight...

    2017 Radiator Failure

    Thanks Gents for the feedback. I am going to replace radiator. Also, this trans was rebuilt 8k ago and started having intermittent shifting issues after about 2-3k, especially after driving a while. After taking it back to the shop and leaving it with them several times and they were unable to...

    2017 Radiator Failure

    A little background on my issue - sent in a sample of trans fluid for testing to Blackstone Labs. The fluid had less than 8k on it. The report came back noting there was a presence of sodium and potassium in the fluid which in their view indicated coolant in the trans fluid. The amounts were not...

    Heater hose Tee connections

    My 07 went at about 195,000, in eastern MT pulling a boat to Fort Peck. It was a real PIA situation. Luckily, I carry a tool box on trips like that and had some radiator clamps and water. Gerry rigged it, to get to the next town. No parts available so had to improve on the gerry rigging and fill...
