    Low Blinker Fluid?

    There are cases where a poor blinker fluid level and winter air not used in winter for the tires, correlate with each other in an unfavorable way and this can lead to undefined problems with the vehicle. Therefore, always change to winter air in winter... I know what I am talking about, I am...

    Bank 1 and 2 lean codes

    So check first the fuel pressure. There is a connection on the rail for that purpose.

    P0446 after purge valve replaced

    If your vent valve fails, the code pops out of the blue, because the system is only checked at certain conditions. When I remember correctly only when 2/3 filled. Can fail electricly or due clocked because of charcoal like said before...

    03 z71 Tahoe didn’t stay aligned

    And check the steering wheel adjustment nut. It's located near the master brake cylinder. You should loosen this, grease the rod and tighten the screw again, so that the steering wheel can be adjusted just enough. This is also where play can come from, which then manifests itself in steering...

    03 z71 Tahoe didn’t stay aligned

    I think the problem will be that you haven't tightened the screws on the upper wishbone, where the camber and caster are adjusted well enough. That's what happened to me too. There are considerable forces acting on it and when you accelerate in a curve, this adjustment mechanism slips. This...

    2001 yukon denali 6.0 oil in cylinder 1 and 3

    Yes, you remove the rocker arms, then the valves are closed. Then you give air pressure with an adapter, which you can screw into the spark plug hole in the cylinder. That prevents the valves from falling into the cylinder. Then you use the tool you see, to compress the valve spring and...

    2001 yukon denali 6.0 oil in cylinder 1 and 3

    Here you see, as an example a valve, from my Escalade where oil comes down from the valve stem seals... I change the valve stem seals as well.. If you know what you do, then you need approximate 3 hours for both sides... If you do it the first time it will take a little longer...

    2001 yukon denali 6.0 oil in cylinder 1 and 3

    If you have oil in cylinder 1 and 3 you should look with endoscope into the cylinder, to see where the oil comes from. If it's the valve stem seals, what is very likely, then you see that, when the valve is opened. Miss firing has nothing to do with that, except you have a lot of oil in the...

    Electric fan wiring question

    I guess you have one ground for both and two plus lines for each of the fans. Just measure the passage. The positive cable must have continuity to ground, but the positive cable don't have continuity to the other positive cable.

    Excessive Body Roll & Self-steer Over Bumps After Front End Overhaul

    You set the wheel upright and measure the angle to the ground, i.e. how the wheel stands in relation to the road. Then you turn the wheel 20 degrees outwards and measure the changed angle. The angle between the straight and 20° position is the caster. But about your problem,. Have you adjusted...

    Power Steering Fluid mixing with brake fluid in brake reservoir.

    That is correct, the hydro boost has a piston which pushes the piston of the main brake cylinder. There is no "fluid connection" which is "separated" by sealings. The main brake cylinder is mounted on the hydro boost, there can not be a crack in a housing where fluids mix...

    2003 Tahoe engine replacement in ATL

    The LQ (6.0) and the LS (5.4, 5.3) a basicly the same engine. The block is the same, just has a bigger bore at the 6.0. So everything like your servo pump, intake manifold, generator and gearbox are compatible, with the difference, that the 6.0 uses the 4L65e which is a reinforced version of...

    What's the chance someone could have jumped my Yukon reverse polarity causing damage?

    I had the same problem, my Escalade was empty after sitting for a long time. and I was hectic and thinking and tried to bridge my vehicle and swapped the poles. It made a violent flash, I removed the cable immediately, but then I had the problem that the car started, but the central locking no...

    2003 Tahoe engine replacement in ATL

    Because most shops are afraid, that there is some incompatibility with electric, sensors, ECM or whatever. And most shops have no time or addiction for research and no interest of recruiting problems. And I can understand it a little, because I have as well the experience that I do something at...

    02 Sensor Issues - MAF, Sensors, What else?

    So I would start logically. The fuel system works as follows. You accelerate and the throttle opens. The engine sucks in more air and therefor oxygen, this is measured by the MAF. Based on this measured value, the engine control calculates the corresponding injection quantity with the help...

    Transmission fluid and filter change at 200K.

    There is a good video from ZF technicians about this topic. ZF is a German manufacturer of automatic transmissions that builds automatic transmissions for BMW and Mercedes, for example. They strongly advise against using additives when flushing automatic transmissions. Firstly, only the...

    Transmission fluid and filter change at 200K.

    That's the problem, even shops that specialize in something, no longer have a clue what they're doing. A friend of mine recently went to an air conditioning repair shop to repair the air conditioning on his bus. They filled the system with refrigerant and discovered that there was too much...

    Transmission fluid and filter change at 200K.

    Then you go to this mechanic who is a pro at changing engine oil, probably replaces the spark plugs and if he is an old and adventurous “mechanic” he changed the internal filter once. But he was very nervous about it. But he never looked inside the automatic transmission or even understood...

    Transmission fluid and filter change at 200K.

    The former mechanic which made a flush without Filter change, did everything right, because in a transmission only a third of the oil is in the oil pan, the rest is somewhere in the system, for example in the torque converter. If you want to change the oil, it doesn't actually make sense to...

    2004 Yukon XL A/C Compressor not turning on

    If you can bypass the compressor relay and the compressor starts, then it is most likely that your refrigerant level is not right. Of course it could also be that the compressor relay is defective. You can simply measure on the control cable whether 12 volts are arriving at the compressor...

    Incorrect fuel pressure Key on and Engine Running

    This is normal if your hose is lower than the level of your tank. Then there is this effect. This is how tanks used to be emptied, the hose sucked in petrol, and the hose hung lower than the tank was full.
