    spark plug change 5.3

    Absolutely agree OP should have mentioned his were disabled, don’t bend those lines or your maintenance will create more maintenance!! im surprised your rear lines are still holding up, I capped mine after second set of new lines lasted 2 years!!

    2012 Chevy Tahoe low oil pressure/ shop says I need new engine!

    I like the oil analysis idea, that will tell if and what parts in the engine maybe falling apart. Isn’t the oil plug magnetic? Cant you just pull the oil plug out and inspect for metal, not as good as the analysis but cheap and easy.

    Need Help With Brake Lines

    Thx T14, I didn’t have that size in my kit and I was advised not to do that as it would cut the threads down a bit and might leak. I looked for a split die thread chaser but doesn’t exist in that size. Good news though, I removed the line from the MC and it looked pretty good, the MC hole is...

    Need Help With Brake Lines

    Hi folks, 2008 Yukon XL SLT 5.3L Flex Fuel. I need to replace my brake lines running from the Master Cylinder down to the ABS module, I unfortunately buggered one of the ends trying to thread it into a new MC. My lines are coated and have M12x1 fittings. After some research, I presume they are...

    A/C Snowflake light on but compressor does not run

    Ok, thx Dave, that makes sense, mine sitting at 50 so looks like it’s were it should be, was at 20 before I added I can and the table also explains why the top of the blue on my gauge is 55. I presume that the table is when system is running so, here is a question for you, you said you topped...

    Battery drain on a 99 Tahoe

    Oh wow!! Sometimes you just never know. That’s a great tip to check that first before moving on to fuses. I had a 66 wildcat that I could take the key right out of the dash without turning it off!!

    A/C Snowflake light on but compressor does not run

    Thx, I’ll try that next if she runs down again. I did see a bit of green leak tek near the high pressure valve so it’s possible that is the problem. Is it the high or the low that is most often to blame? Also, what pressure should I have on the low side, I read another post where guy said he...

    2006 Tahoe/AC charged but Compressor not turning

    That’s a good start but swapping the relay only proves it is prob not the relay, did you jumper the pins to put voltage to the clutch as I suggested?

    2006 Tahoe/AC charged but Compressor not turning

    Awesome find!!! Luv it when it’s that easy. Our OP sounds like he is having a bigger issue but always start with the basics to see what you got.

    Battery drain on a 99 Tahoe

    I don’t always agree with Scotty but I used this method on a 97 civic and found several draws. The battery would go dead in about a week. The 1 ohm resistor method is great as you can hook up the shunt and monitor your voltage over time and the battery is still hooked up so all the modules stay...

    2006 Tahoe/AC charged but Compressor not turning

    I was just dealing with a similar problem yesterday on my 08 Yukon. If you jumper pin 87 to 30 this will put power to the compressor. You can do this key on Eng off and you will hear an audible click from the compressor, that tells you the power is making it to the clutch. If you do this eng...

    A/C Snowflake light on but compressor does not run

    Thx 972 for your time. I analyzed that relay from the fuse panel diagram and sure enough, it’s the outboard posts 85 and 30 that have the pwr which is the way it should be but I realized that the relay was in upside down but I checked it to the fog lamps relay and the fuel pump relay and they...

    A/C Snowflake light on but compressor does not run

    A/C was charged last year and worked fine but slowly got less cold and then the snowflake gave the 3 flash mode. I presumed a slow leak and bought some stop leak and was gonna give a try. I hooked up and system pressure shows 20 psi and is enough I presume to command system on because snowflake...

    2003 Chevy Tahoe- Transmission Fluid Change

    My 08, the downpipe nuts are pretty hard to get at with the cats in the way, i just took the hangers off the exhaust and let it drop down a bit and a pry bar and gave lots of room to get the pan off cleanly.
