    Smoke testing Procedure help needed

    Don't forget, the smoke can escape through a leak in the brake booster's vacuum circuit.

    Rear Control Arm Attachment Problem

    Well, I didn't notice any smell, with it in my garage with the door shut. When I pulled my tank, there was a lot of gas in that depression. I jumpered the pump relay to remove the gas, so I could handle the tank, as it had 10–12 gallons in it. I did cut a hole above the pump while I had the...

    Rear Control Arm Attachment Problem

    If the repair is on the left side, be careful to protect the gas tank from sparks. The metal lines on the top of the fuel pump rust also. You might find a pool of gas in the little well where the pump mounts.

    Fuel pump only replacement 07 suburban

    Thanks for reserving judgement. I did it under awful conditions. I had just delivered some prototype vehicle body assemblies, and I had to do this right in the customer's parking lot. He helped as I hacked the hole with the side of a screwdriver. He stayed while I did the whole job and still...

    Fuel pump only replacement 07 suburban

    I just cut an access panel above the pump on my 2007 Yukon. Seal it up good with heavy fabric tape so fumes can't pass through. I had to put 8 pumps in my 1996 Chevy Express van, and that convinced me to always do this.

    What year would you avoid in a Tahoe or Yukon?

    The "ignition off drain" issue is so ridiculous, none of the industrial electronics those vehicles are made on would lose memory if left off for an extended period of time. The welding control I supplied to all of the GM Truck assembly plants could be left off power for four years, without...

    2007 Yukon..Common places to check for coolant leak.

    My 2007 leaked along the rear heater lines, aluminum tubes tightly clamped every couple feet to the rocker panel. Leaked at a couple clamped areas. Rather than redesign that method of mounting the hoses, I just capped them off. BTW the AC tubing was already capped off... Many stories on the...

    2008 Tahoe LTZ. No oil. Added 2 quarts, dipstick still doesn't show anything.

    Is the added exhaust near anything it can touch when the engine moves as you put it in gear?

    Crazy screeching noise from '03 6.0

    I had a similar problem years ago on a small block Chevy, due to misaligned pulleys. As the serpentine belt traversed across the smooth tensioner pulley it was dragged sideways just 1/8". I had to move the alternator back 1/8" and it was finally quiet. I discovered this by putting straight...

    What are your must-do things on new-to-you gmt900?

    Check the mounting bracket for the drivers side rear lower trailing arm. In the rust belt, they rot out and it is a big deal to repair.

    need help identifying/naming rear frame part

    Just discovered this thread. Did the same with my 2007 Yukon. Son-in-Law donated it to me, and it had broken completely. He still drove it from repair shop to repair shop, no one wanted the job. Says it drove OK, just had this "clunk" sound. The rear end is still attached by three trailing...
