Almost got rid of my 2005 Denali XL

[Chip18]

Guy charged me 330 to fix one coil. Told me it misfired 1100 times.

Im not a mechanic so I have no idea

OK ... that's a bit different! But that does not mean you have to get screwed to the wall. The internet is your friend.

Coil packs are on top of the engine ... they should not be a "difficult" remove and replace job?? But ... little things ... clips can get broke and bolts can be stripped!

A torque wrench is your friend! It would be "inch lbs for something like this and a "Manual" for specs or ... "ask" on here.

So those would be minimum requirements for the "DIY" route. But ... ask around for a shop "I do know stuff" but time and place needed a motor (swap) in my little Tercel original was "finally blown." Shop said "no problem."

I'd have prefered to do it myself but ... no time. I met a "guy" and he seemed to know what he was doing?? He did not, 3 months and $2500 dollars later and "Tercel" was turned over and it ran "worse" than it did when it came in. He even jacked up the T-Belt job!!!! The fact that he would call and ask me questions about the swap, that I would answer ... should have been a clue??? In retrospect, I should have just had him bolt the motor in and had it flat bedded home.

A timing belt on a Toyota DOHC 5efe is as simply as it can get! He put it in wrong and that's what broke the motor, I was double checking everything he did and found it!!! Aww well turbo motor when I get back to it.

But ... later we asked questions, family, friends and found a real shop! And they give a "One Year" guarantee on there work and parts! The first shop I used .... yeah ... they had no guarantee.

Not saying you can do it yourself but at the bare minimum shop around and ask about a warranty.

Yeah, it looks like you can buy all 8 for $160 and very easy to change them out. I've never done them but just looked at 1A Auto's YouTube video and it looks easier than changing spark plugs. Google " replace coil packs GM 5.3" Your 6.0 will be the same. Anybody can do this, don't pay that rip off shop.

LOL ... yeah ... I'll have to look there to see how to change the spark plugs myself!

I can "see" all of them but not really clear on how to lay hands/tools on them??

 

[Chip18]

Wow. The sad part is hes a mechanic from a friend. He works on me, him and our bosses trucks.

Thats sad man. Cant trust anybody now days

Ugh .... well so much for asking family and friends!

So interestingly I pulled up to a clients work location to detail his new ford work truck this afternoon. The son in law saw my Denali and was like damn that's a nice truck. And then he proceeded to ask my right off the bat if I'd had any problems with the coil pack, cuz he dad just bought a 2003 with roughly 130k and it had a bad ignition coil pack. Weird that I'm reading through this thread tonight haha.

There's no need for a torque wrench! Like the video says, a 10 mm socket and extension. This repair is so easy , don't make it difficult!

OK I'll find it ... thanks.

Not tight enough, Coil Packs fall off, too tight and bolts "Snap" ... then the "New Skill Set" becomes ... "Bolt Extraction" and "Thread Repair."

An "inch lb" Torque wrench is cheap insurance.

There is NO torque specs for those bolts,so exactly what spec are you going to torque those to? If you feel the need to start using a torque wrench to tighten down every bolt on your vehicle, you probably shouldn't be working on it. And definitely NOT advising others on how to work on theirs. Now, a Harley-Davidson, there's a machine that needs nearly every fastener torqued to specs due to the vibration, but there ARE specs listed in the service manual for those fasteners. If the specs aren't listed, you don't use a torque wrench. Period.

Like most that wrench on cars ... all the time I reserve my torque wrenches, for Head Gaskets, Timing Belts and Precision engine work. Should use them for suspension work ... but so far ... nothing's fell off.

The OP said I don't do car stuff, to me that says ... how tight is tight enough??? "Johnny Hamfist" would have no problem snapping off a bunch 10 mm bolts "those are the folks who should "Use a Torque Wrench" ... pretty much that simple.
