Time to replace my spark plugs, I've never done it before on my own. Now it's time to, and I need to know what plugs you guys recommend and all that jazz.

 

Also, I know it's been discussed, but I have a loud squeal on cold starts. It goes away as soon as the engine warms up. I tried lubing the bearings in the pulley? or something like that haha, someone suggested that a while back. Think it's the belt? If so, what belt should I buy?

Thanks guys!

Yea stay with Ac Delco or NGK. Don't bother with those 3E spark plugs, pretty much just hype and no benefits with those plugs.

 

The chirp or squeal sounds like belt issue, good thing you only have one on the motor. Any brand is good for at least another 100k miles.

I'd stay with AC plugs..... And as far as I'm concerned a belt is a belt so that shouldn't be a problem but saying that we use Gates on everything we replace (tractors semis trucks etc.)

I have had more GM trucks come in with misfires due to non-AC Delco plugs being installed than I can

remember. Stay with the factory AC Delco replacements for your truck, you'll be glad you did.

 

The chirp is most likely your a/c belt. Give it a light squirt of PBlaster when it is chirping. If it goes

away, you have your answer. Common issue with those trucks.

use the ac delco factory plugs. The noise is more than probably your ac belt like everyone is saying replace both belts while you are in there. The previous post recomended using pb blaster to diagnose it thats not a fix nor is any type of belt dressing for that matter.

AC or NGK plugs, I just pulled NGK plugs out of an 04 suburban. They were the original plugs at 150k miles. They didn't look bad other than having an .080 gap. :)

 

How many miles are on your truck now? I generally like to change out my belts on my 02 Silverado at 60k or so just to be safe. The chirp could also be the idler pulley. Gates are a good brand to get for replacements.

Nor did I imply that it was, either. :D

 

P.S. It's spelled PBlaster not PB Blaster. Lost that discussion once myself until I read the can. LOL!

Quick diagnosis, and rule out the pump. :)

ended up doing this all last night. truck has 85000 on it now, got it with 78000. didn't have any idea if anything had been done before so i've been slowing doing it all myself.

 

replaced the plugs with NGK iridiums, and replaced the main belt with a gates one. didn't think about the a/c belt, but when i cold started it this morning it was chirping still, so i looked down there and the a/c belt is clearly worn so i will do that this weekend if i can make the time for it.

 

thanks guys

      Some Assembly is Required

      Hi, New here.  2026 Denali HD.  Just purchased 7/2/26. I am having the same issue.  I just traded in my 2024 AT4, and the truck connected to bluetooth and Android Auto Immediately!  Now, with the new HD, it connects when it wants to, which is usually not at all.  I have to use the usb-c cable to get it to connect.  Bluetooth won't even connect without the AA. Now after saying all that, I'll take a 20 min drive with the phone plugged in.  Stop at a store, restaurant, etc....  Get back in my truck and DO NOT plug the phone in.  The truck then decides at this point, lets connect BT & AA and work perfectly, ie how it should.   I have deleted (forget phone) the phone multiple times.  I guess I'll just get used to plugging it in every time. even though I don't think its good for the phone battery to have it on charge after it hits 100%. I have searched all over.  No one else seemed to be having this issue, until I read this thread today.   thanks for reading.

      2004 GMC Sierra Crew Cab Ignition issues

      By Heath · Posted

      I have an issue with my ignition hanging and I have to tilt the steering wheel to get in the off position. I have used a great key lock spray and it doesn't help resolve the issue. Is this an ignition assembly issue or something else. If anyone has a past experience with this please advise.   Thanks  Heath

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By jl6690506 · Posted

      This is a terrible GM warranty experience, two months waiting for a covered engine swap with no loaner or timeline is not allowed under GM’s courtesy transport policy.Escalate straight past regular support to a GM executive case manager, document every closed service ticket and dealer repair paperwork. File a complaint with NHTSA to force faster action, and ask for daily rental reimbursement while your truck is down. If it’s been out of service over 30 days, your state lemon law may let you pursue a full vehicle buyback.

      2019 GMC Sierra 1500 - 8l90

      By jl6690506 · Posted

      198°F isn't unusually hot for an 8L90, so I don't think temperature alone caused the issue. Since everything returned to normal after the truck sat for several days, I'd be looking at an intermittent electronic or hydraulic control problem before assuming the transmission itself has failed. The first thing I'd do is scan the Transmission Control Module (TCM), not just the ECM. GM transmissions can store manufacturer-specific or history codes that won't trigger a check engine light. I'd check: TCM history and pending DTCs Commanded vs. actual gear Line pressure Shift solenoid status Torque converter clutch (TCC) slip Transmission fluid temperature If it happens again, try to capture the data before cycling the ignition, since some intermittent faults disappear after a restart. A professional scan tool that supports full GM transmission diagnostics makes this much easier. For example, the Foxwell NT809BT can access the TCM, read manufacturer-specific transmission codes, and display live transmission data that's not available on a basic OBD-II reader: https://www.foxwelldiag.com/products/foxwell-nt809bt Hopefully it's just an intermittent control issue, but I'd definitely pull the TCM data before replacing any parts.
