That was a job well done

The only bad thing is, im spending more on aftermarket parts for my truck, than what my truck is worth😂.

and this is why i LOVE 1A Auto !!! Great install videos and the TRQ brand parts have been fantastic ! My 2006 Silverado Z71 front wheel bearing hub assembly i got from 1A Auto 3 years ago is still working perfectly and was only $79.95 (or both sides run $129.95 i think as a set but i was on a budget at the time and only ordered 1the side)....

Make sure you disconnect the neg. side of battery before you start disconnecting wires

[Ghst]

Got a misfire in cylinder 6 replacing coil and wire hopefully that’s fixed the problem

[edwardpedroza]

Is there any diagram for the coil pack? I was told if you don't follow the correct diagram it will still misfire and cause the check engine to either come or stay on. I didn't see you used a diagram. Any thoughts? Thank you for your videos.

Could yall do changing transmition fluid and power steering fluid?

Can you post a link of the whole set of ignition coils, cables, and iridium spark plugs from your brand also need front both sides upper control, arms and camber kits for my 2000 Silverado 1500 Z 71 4 x 4
Because apparently the shop can’t align it with my brand new K02s without changing all of those parts

My 04 has square coils and 10mm bolts. Same 5.3.engine. odd...

[JuanGarcia-znlf]

My 4.3 has 1 coil, I change it but it won’t crank until I unplug it and plug it back on, then it will start until it goes cold again on next start

[wii]

does it matter if i get a square coil or round?

[masonpugh]

Great way to do it but I didn't see the left side it' was tuff

[SACRAMENTO_]

Is the code p0300 is it the spark plug or ignition coil?

[jakecorkins]

Can confirm those coils right there don't fit on a 2005 chevy silverado 2500hd with a 6.0....

This video is useless for a 2004 Chevy Silverado. You need to rename with the proper year and make. It looks like you don’t really know the proper year and make and hurts your credibility.
