    Service 4wd - but only in 2wd

    Well Grounds / connections all looked OK. Pulled them off, sanded down, dielectric grease, and some water proofing on top. Removed the plugs and noted no corrosion in the pins. No change. Ordered the sensor ring based on a best educated guess. I really should get a proper scanner..... But...

    Checking Possible Rear Main Oil Leak at Bellhousing

    Flex plate: Not necessarily. That only means it's not dripping onto the flex plate. But there's no law saying the oil has to travel from shaft to flex plate. Oil pressure: change the oil again. See what happens. Could be filter plugging up, oil shearing down, gauge being funny, fuel...

    Radiator keeps taking my Transmission out

    Jesus So.... If THEY did the radiator, transmission, and install. Don't dick with it. Take it back and let them sort it. Once you start poking around, you give them cause to deny warranty. As far as the milkshake: See if you can send a fluid sample out for an analysis. See what's going on...

    5.3L Running Around 185 degrees after thermostat replacement

    Yep From my digital readout, lower bound for temperature is about 192 if I'm coasting down a hill, to 197 if I just get off the freeway and come to a stop, excluding activity from radiator fans. And that's with OEM. Previous aftermarket tstat would be anywhere from 203 to 217. And that was...

    Chrome Wheels Blistering

    Yep, leave those. That's from someone loading it on the tire machine wrong. There are 2 ways of clamping a wheel: From the outside - jaws w/ plastic liners grab the outside of the wheel near the tire bead. This is what you use for alloy wheels / powder coat / clear coat / chrome / etc etc...

    Mystery noises in engine bay

    Good to hear on the alt IAC: If it happens reliably on shutdown, give the thing a start, unplug, then turn the engine off. Note if the noise occurs. Someone check me on this as it's been forever since I've diag'd IAC issues: But take the thing off and give it a shake. If the pin rattles around...

    Anyone find a way to engage A/C compressor when below 40 outside?

    I could.... But that's cheesy I actually looked into programming the BCM but couldn't find any information either way

    Anyone find a way to engage A/C compressor when below 40 outside?

    Yeah you don't want to do that chief. That limit is there because of the saturation temp/pressure. Lower than that and the thing is going to lose phase separation between gas and liquid state. Ever seen what happens when you hydrolock an engine? Same gig in your compressor. Meanwhile I'm...

    Mystery noises in engine bay

    Clicking: Sounds like evap purge solenoid. Check is to remove the engine beauty cover - single 8mm bolt. Pull up then forward. It's a vertical thing with a hose and a plug on it just behind the throttle body. Remove the electrical plug. If that is the noise - well... A new one *might* be...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Yes but not for a leak Had some abrasion concerns against the top of the hood so I put a sacrificial layer on there Strictly speaking it's self-fusing tape. Electrical tape would get nasty with under-hood heat and weathering Edit: I'm looking at it and realizing that's probably what the loom...

    Service tire monitor

    Both the 2019 and the 2004 sensors work on the same 315mhz band. Who knows, they might work? Worth a shot. Just need to do a relearn. It's a little clunky, but I'm rather fond of Chevy's implementation as it doesn't require any special tools. To do this: 1. Apply parking brake. Turn ignition...

    My carpets make me gag. How do I clean them?

    Nice thanks guys!! I popped the seats out and gave it a good 'ol suds and scrub and scrub and scrub and suck and scrub and scrub it's a whole shade lighter LOL Had a couple stains that are there to stay. But they at least lightened up. Replacing the carpet ain't a bad idea tbh. Will...

    My carpets make me gag. How do I clean them?

    Previous owner did a number on the interior and I'm only just now getting around to it. Decade old coffee stains, sugary drinks, stuff that was under the floor mats, couple mold spots from a water leak. There are some spots that are so gross and sticky I can leave thumb prints. I'll put it...

    Mystery noises in engine bay

    For the water pump: Get OEM. At least on the thermostat side. I actually just replaced mine because it was being dumb. It worked, technically, but big temp swings. Never showed on the gauge FWIW - only saw on a digital readout

    Misfire on Cylinders 1 & 8

    Damn I read right past that!! Test all Oil leak: Not directly. But if you say.... ran it out of oil and damaged the engine, then that could cause a misfire.

    I need experienced help re: Water pouring out exhaust

    Help with what? A leak's a leak. Making a clot around a hole won't fix the hole. Might be a handy thing to keep in the glove box if you're off the beaten path, but I'm not sure I'd use those as a fix.

    Misfire on Cylinders 1 & 8

    Adding to what 'Vette said: check fuel trims - could be first pointer to a vacuum leak. Or exhaust leak. Aside from being dangerous... Atmospheric air intruding into the system is going to throw the oxygen sensors for a loop (no pun intended) could also swap injectors around and see if the...

    I need experienced help re: Water pouring out exhaust

    Quick and dirty test time Put the heads back on drill+put a an air tool fitting in the reservoir cap, connect up the coolant hoses or plug the holes, set the pressure regulator to 8-10 psi don't bother connecting the exhaust headers Yeah it might take you a couple hours to do, but in the...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    even that, I don't understand? The pulley bottoms out against the crankshaft. Once that happens, it's essentially "floating" as the only pressure applied would be a result of the belt. Thrust bearings constrain the crank shaft in the forward/backward direction. So... Hell if I know Didn't...
