    2005 Tahoe Slow Coolant Loss

    2005 Tahoe LT 5.3L, 220k miles, LM7. Slow coolant loss—no puddles, no drips, no sweet smell inside, no codes. UV dye's been in 10k miles—black light shows no leaks anywhere, no clear streaks or trails. Perhaps I am missing something common? Water pump replaced at 150k by prev owner, thermostat...

    Pin diagram needed for Z55 air compressor connector

    Hello. Does anybody have the pinout description of this air ride compressor connector? I have a few rusted eroded pins as you can see that need replacement. I would rather repair the 2 pins than buy an expensive pigtail. Thanks much!

    Oil pressure all over the place - SOLVED

    So I put that Valvoline Restore 5w-30 in my truck 3 months ago. For the past few days I've been getting the bells and DIC warning of low oil pressure. The dash gauge goes back and forth from 0 - 40 psi many times during a 5 mile trip. I checked the oil level multiple times and it is full on...

    What's left?

    Through the years my 05 Tahoe has been mostly gone over 2 or 3 times front to rear. It's arguably been refurbished and serviced more than it deserves. Most major parts have been replaced including fuel pump body insulator mounts, heads refurbed... the usual tuneup and all steering and brake...

    Rear window not working

    My driver's side rear window won't roll down anymore. I can hear the relay activate back at the door but no roll down. Either motor or sticking window because power is getting back there. Just wondering if anyone has any experience and can provide a quick solution? I would rather not have to...

    New cam and higher # injectors?

    I'm in the process of replacing my cam. I also taking this opportunity to ultrasonic clean the right side bank of stock injectors on my LM7 engine. I got the cam stuff down pretty well (it's an Elgin step up mild cam). I didn't want a funny idle or a higher rpm torque band that requires a new...

    Air pump electrical connection

    I was using my scan tool the other day and noticed some codes for the air suspension pump relief valve. So I checked the air pump and disconnected the air pump electrical harness. Upon inspection I noticed the power red wire completely rusted away. I've been looking all over online for either...

    Air conditioning compressor clutch

    I noticed my A/C wasn't working today. The interior fan works. I checked the underhood fuse and relay. They are working. I also jumped the always hot pin of the relay socket to the pin for the compressor clutch and the clutch engaged. Also the PCM side pin to operate the AC relay works as...

    Loosing coolant. Underhood coolant smell

    I was working under the hood today and noticed my coolant reservoir was halfway empty. It was fine a month ago when I added a few quarts. It was just below the line about 1/2 inch. I also have been smelling hot coolant around my radiator shroud/ front of engine area. I don't have any leaks on...

    Hey everyone I'm hearing a metallic rattling noise coming from the right front wheel area that seems to be getting worse. The sound only happens when going over small bumps in the road.

    Heater fan randomly turns off

    Hello everyone. The other day after replacing the drivers side window motor on my 05 Tahoe I noticed my heater fan turning off for a few seconds and then comes back on and continues blowing like normal.

    Large engine misfire at idle

    I noticed this morning my engine was misbehaving more so than usual. I noticed that when it idles and maybe off idle?...the engine randomly shudders or misfires. Feels like someone cycled the key very quickly. Almost feel like the engine is about to stall. So I bought some Berryman cleaner and...

    Vehicle pulls left or right when braking

    My 2005 Tahoe LT 4x4 seems possessed. Does anyone know what would cause the vehicle to pull randomly to either side when braking only? I realize that the primary cause is usually a bad caliper but if it randomly pulls to the left or right...what would that be caused by? It's very odd behavior...

    2005 Tahoe..Engine hours on DIC starting from 0

    Odd...for some reason (maybe not?) The hour meter in the DIC shows 8 hours. It used to show around 1560 or some other bigger number (supposedly legit). Anyone know what happened here? Is my PCM overwritten?.

    Cadillac Smooth ride suspension

    One of my colleagues at work has a Cadillac . 2007 model I believe. He says it is the best ride so far for him. He previously drove Tahoe's and Yukon's. My question is this. Can the Cadillac provide a ride experience better than the Auto-ride suspension which is found in the LT Tahoe's or...

    Left Turn Fuse Keeps Blowing

    Was wondering if someone can lead me looking in the right area for this issue? I know this has come up many times before by searching...just didn't want to hijack any prior threads. Also, the answers to each left turn fuse issue seems to be slightly different. I keep replacing the 10 amp left...

    Time to replace battery?

    I was looking at the date on my battery the other day. It's a Duracell AGM 34/78 from Sam's club bought in 2013. Just wondering if replacing an AGM at 5 years is prudent? I have read that AGM's last twice as long (10 years?) than a normal flooded lead acid battery. Just looking for opinions on...

    Brake performance issues

    As of late my truck seems to be gettting harder to stop. When coming to a stop light it feels like i am going to glide right into the back of the car in front if me. In other words it seems as if I need to press the brake pedal much harder (lack of boost?) than normal. The brakes feel like they...

    Hard to turn steering wheel in parking lot.

    A few years ago in put in a new power steering pump and it's just never worked well. It still has poor assistance when in parking lots and other low speed maneuvers. I'm about to spring for another pump but thought I would ask here first with all the experience and stuff. Does putting in GM...

    New CV Axle leaking

    Not 100% sure about this...but are the aftermarket cv axles supposed to leak any amount of grease at all? There is some black moly coming out both sides of the driver's outboard boot.

    Want to start a 6.0 HO project...

    Can someone point me in the right direction to find an 6.0 or 6.2 HO block? I test drove a 6.2 Maxx one time and loved the throttle response and torque. Can these be retrofitterd into a NBS engine bay? I'm assuming there are no factory compatible PCM's...could be wrong. Just looking for a stock...
