    Can anyone help me find out what happened here?

    The problem is probably the disconnected little hose, that's a PCV hose (Fresh Air) that is connected to the intake manifold, you need to remove the engine cover for access, There should be a port there. Oil is probably coming from the intake manifold PCV port, if the catch can is full or almost...

    Entire strut assembly part number?

    I installed these ones on 2016 (ACDelco 903-040RS), And everything is good, no problems at all and it seems to me the truck got leveled (not like a lift kit I suppose, but looks better), somebody told me it will settle in a few months but has not happened yet after 2 years. I know it is weird...

    Range AFM - LED light questions

    I am planning to get one of these cables. You can just turn it on/off when you need to. And if you don't like the device's light you can just hide the device behind the center console or dashboard.

    Have an '08? Replaced TPMS sensor(s)?

    Thanks for your help. I suppose I will be the one testing them and reporting back. You are righ, any of them have replaceable batteries but these ones have just two contacts soldered to the PCB and the sensor seems easy to open, This kind of batteries are everywhere, you can buy them very...

    Have an '08? Replaced TPMS sensor(s)?

    My front left sensor is also going bad. Did you buy the part number 13598771? Apparently all the part numbers listed below can be used in our trucks. But the newest one is 13598771. I like the new style because it seems to me the battery could be easily replaced. Let me know if you bought the...

    '07 GMC Yukon XL Denali AIrbag Erroe Code - B0084-39

    That would be easy then. I have no idea about the part number change but sometimes the factories have material shortages and they use replacements, assuming it is the original sensor from the assembly line. Sent from my iPhone using Tapatalk

    '07 GMC Yukon XL Denali AIrbag Erroe Code - B0084-39

    Yes, they are the correct part numbers, Dorman brand should be OK, I have purchased Dorman replacement parts before and they have good quality, fitment and perform well. Since Left and Right sensors are the same, I would change positions (Left to right & Right to left) and scan again just to...

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

    This is a guide I found online and it is exactly what I did: Make sure your engine is warm. Not hot. Just let it run for a few minutes. This will help loosen the dirt. Cover the alternator, battery, and any wires/plugs/important parts if you have concerns. LIGHTLY spray down the engine...

    I just covered the alternator and battery, You're not really going to hurt much of the electrical components with clean water, all the connectors have seals that keeps moisture out. Never use a pressure washer to clean the engine.

    The truth behind synthetic oil (my story)

    It's a 2007 tahoe with 82K miles, I change the oil when the Oil life Monitor is at 20%, I also track my miles and I get around 5K miles between oil changes.
