Great video! I recently purchased a 5.3 envoy and have been watching all of your content on them Thank you!

Great presentation. I’m considering buying a 2003 Envoy with 94k miles that’s been garaged for the past 5 years, one owner. I’ll come back to your videos if needed.

First thing to do is clean every ground wire on the truck that got rid of over half my electrical problems

Got my 05 Denali… after previous owner (my buddy’s mom) handled costly repairs …. full transmission replacement Rear Air ride susp swapped -springs etc I purchased for $2500!!! (us) less than half of kbb value! Mysterious electrical issues at first with spontaneous shut off. Unresponsive etc.. (figured out it was the under hood fuse box itself! Factory replacement =perfect I’ve since done water pump myself… Upper a frame (front right) and ball joints (all). Been awesome vehicle @187k * although low oil pressure is the newest “to do” I hope I don’t need to drop the pan to do the pickup tube o-ring… but prob is my issue

Is $1000 for a 2003 gmc envoy with 220000 miles on it that runs and drive a good deal? Transmission rebuilt at 180000 and new water pump. I think its a steal but wanna be sure.

If you’re getting harsh 1-2 shift check mass airflow sensor. I had same shift problem, no codes, after research checked mass airflow sensor readings. Replaced and shift returned to normal.

Excellent video. GM destroyed the 5.3 after 2005 with the DOD system:(

Hey I got a quick question that doesn't really relate to mechanical issues but rather a radio wiring one, I have an 04 XL with the Bose system and need accessory power for my new system - which the OEM system doesn't have. Is it possible for me to route power from the Onstar system to act as the accessory power? Thanks in advance.

Awesome video! I have a 2004 Buick Rainier with V8. Do you think changing the ATF will help the tranny slip?

Hello I have a 5.3 envoy but now the engine doesn’t turn but ac compressor was making noise thank you Nicholas

My 2007 5.3 has 230k miles and still running like new

You forgot the HVAC fan motor resistor, I mean its a common issue for all GMs during this era but they seem to only last about 40k-60k miles. Same with the blend doors, their made of plastic and tend to strip out and get stuck in one position.

Couldn't have asked for a better video. Question, I am looking to buy a 2008 envoy Denali with 122k miles. It's a single owner vehicle, and in above average condition for its age and miles. I'm looking to replace a 03 lesabre as my back and forth to work vehicle. Would this be a good vehicle to buy considering the miles? The price is $7500 US. If yes, is there anything I should check or inspect prior to purchase? Thank you for you time.

Why do I need a smoke test 07 gmc envoy

I. Have a 2005 gmc Envoy Denali, and It just quit in traffic one day. I changed the fuel pump,ignition switch, crank shaft position sensor, and underwood fuse box. It will crank and run for about an hour or so, then it shuts🎉 off and will not crank again till later after a few hours or not at all for a day or so. I've had it in several shops, including the dealer, and no one can seem to find the issue. As knowledgeable as you are with these vehicles, do any ideas pop out to you, sir?

I want to buy an envoy 2003 v8 like this Its good or no? Im from lebanon

Working on 1 right now with 325k miles

Im looking at a 2007 gmc envoy for $1800. Is that worth it? I need help trying to figure out if i should get it or not. Can you take a couple minutes to answer a few questions i have?

you said they all have it.(denali) then u said that dose not. was it taki en off

You don’t have to rebuild a engine or replace a engine because of a bad lifter stop giving people false information all you have to do is replace the lifters

Temp sensor
