- At first Acadia had problems with the timing chain and errors associated with the chain. I replaced the timing chain and showed you how to do it yourself. Showed where the timing chain marks are gmc Acadia. Replaced the water pump, replaced the alternator belt and also the tension roller. Replaced all the seals and gaskets. Replaced the spark plugs. I assembled everything, poured in new antifreeze and engine oil. Made the first engine start and heard strange sounds and also replaced that the engine was shaking a lot. Connected the launch diagnostics and saw the error p0019, I don’t know what the problem is and will try to find and fix it. In the next video I want to show you what my problem was. Thank you for watching my videos. Leave comments and don’t forget to subscribe to my channel.

One thing I've learned, especially for this engine, is to always buy OEM AC Delco timing chain kits-no aftermarket chains, period! I used to use Cloyes in the past, but they've outsourced their manufacturing to China, and the quality has gone downhill. So far, two mechanic buddies of mine installed made in China Cloyes timing chain kits that broke at around 5K miles after being replaced. One was for an Acadia and the other a CTS. BTW It sounds like it jumped a tooth. A helpful tech tip: you want to prime the chains first by pressing the gas pedal all the way down, holding it, and letting the engine turn over for about 5 seconds. Do that a few times. What a lot of people don't know is that those engines are prone to jumping a tooth or two if you just start the engine right away after a timing chain replacement without doing that step first. Also, be sure the cam sensors, VVT solenoids and sprocket/phasers are super clean. Sometimes the sensors will throw an error if they are excessively tarnished. Anyhow, hope you get it running👍🏻
Thank you so much. I think maybe the phaser is faulty. Or as you wrote, the chain jumped. In any case, I will find this problem and make a video about it.
