It was probably so nice having some elbow room for a change.

Always good to have liquid water on hand. Solid water works poorly.

And why a lot of us still hold onto our older vehicles. Simplicity and ease to figure out.

As a newly qualified mechanic who did almost 6 years for my apprenticeship I have to say i love watching your videos, im constantly learning new tips to diagnose things like that with the rubber glove was awesome and I hope to show it to my old man soon to impress him. You guys work like art. I love to see the passion and great brains and I wish I knew half as much as you Dave

My brother had an old Blazer that had starting problems especially on rainy days. It was night and I cracked the hood open a bit and asked him to start her up. With his two boys standing next to me gawking inside under the hood all I could hear was "wow, Uncle Ed". It was a light show under there, flashes everywhere you looked, like looking down on a thunderstorm from the space station.

‘Liquid water’ my favorite!

"Umph": Old skool term for compression. Used in a sentence: "It's got no umph" I've owned many gas engines like that Chevy featured in the vid, including a small block 350 Suburban. I was mostly a MOPAR guy owning vehicles with slant 6s and 318s. No matter what make I owned between the "Big 3" auto makers, they were very easy to diagnose and work on and inexpensive to maintain. I remember when starters and alternators were rebuilt and sold for a song and dance of $20-50 back when. Now in the present, you add a zero to those prices that I listed. If you own old and it's fixable, keep it, fix it and keep driving it. It's worth it. Thanks again Dave!

Man, what a beautiful truck. I love the older stuff so much more! ❤

Ha ha ha. Excellent Dave. 👍🏼👍🏼 I think everyone has an old ignition story. Mine is similar to everyone’s. 72 ford ltd wont’t start / run when it had rained. Cracked the hood and had them crank it. The old original motorcraft wires were leaking lightning everywhere. Luckily I had brought the economy size WD-40. I hosed every wire, spark plug to cap, waited 5 minutes for the silicone to displace the moisture and the car started. I gave them the spray can to keep in the car and told them to get me a good 8mm replacement set of wires. Two weeks and another paycheck in their pocket later, and I showed them how to replace their wires one at a time. Good memories. Thank you Dave. ❤️🙏🏼

I had a 1993 Dodge Caravan with that sweet little 2.5 Chrysler and a 5 speed stick. I believe in if it ain't broke don't fix it. It started giving me trouble, especially in wet weather. I looked under the hood one rainy night to see a light show. The next time it rained I barely made it home. I bought new plugs, wires, cap, rotor and a battery. The 48 month battery was 9 years old. The plugs had burned the electrodes right off. She hadn't had a tune up since new but after that she ran like new again. The clutch went over 220,000 miles. That little minivan was a real trooper.

You and I grew up in a great Era !!! From Magnito's to multipoint ignition coils... What a thrill to see your videos !!! Especially when it is some good oldies.

That blazer is cherry. My friend had one just like that but it was white. It was awesome.

What a beautiful K5. I checked the coil on my 95 Astro....at night. When I revved it, coil would turn blue and motor would start missing/losing power.....some of the old tricks really work.

that’s how you know you’re a master at what you do …love working on this older stuff, we still like to do it”

Beautiful vehicle. !!! They don’t make them like that anymore. Simple and easy to work on.

Had a guy broke down in front of an automotive parts store. It was a humid misty day. I had him get in the car trying to start it and you could see the coil had a lightning ark through a crack in the coil and it was shorting itself out.. The guy said he only had trouble when it was raining and couldn’t figure out what it was. I got in it and cranked it over so he could see the crack and arching. about 20 minutes later he come out with a new coil and installed it in the car and it ran fine. Nowadays, it takes some high-tech diagnostic machine to figure it out.

I remember maybe 20 years ago my friends mid 80s accord always ran crappy. One night he popped the hood and was looking at things and all the spark plug wires were arcing to bare metal. It was quite the light show

The one person i wish had longer clips 😊 always leave his platform hungry for more

Dave, that was awesome. That's why I call you the Colonel. The way you said Lightning was similar to how you say "Boo!"

One of the only guys i follow. Good teacher and mechanic.

Love the real cars and trucks. Very satisfying to fix and drive. The new stuff just doesn't have it.

Squarebody baby. Best lineup ever

Gas engine needs the FACTS F- fuel A- air C- compression T- timed S- spark Keep up the good work!

KNOWLEDGE IS POWER. GREAT VIDEO GREAT KNOWLEDGE.📡🇺🇸👽

That's a beautiful square body Chevy!

Drove one of those in high school man I miss that truck

Thanks for the 1980 shop class 👍

I love the old stuff brother

Love that old Lincoln in the background!

Hola 👋 señor Dave!!!😊 what a great trick to diagnose the problem You have always an ace under your sleeve…great job great video…Saludos!!!👋😃👋

This guy just seems like a good dude. I don't let people work on my cars, I'd rather do to myself, but I would let his shop repair my cars if he were local.

You’re the best Mr. Dave and the boys always great information. Thank you for sharing. God bless you.

Did Dave just say liquid water lol. Love the videos. Thanks for the knowledge Dave. You have taught me alot about engines.

Dave's saving the dinosaurs!👍

These mechanics are lucky to work under this guy. He will teach them things they never knew possible and they will become masters themselves

That truck is a BEAUTY. I love my old Chevys

Liquid water? Didn't know there was a choice. 🤣 I enjoy your videos. Always something interesting to learn.

"Engines need three things" ... Proceeds to list four things

I just got my 85 Elco not too long ago so this is Great to know thank you for spreading knowledge to us younger generations as very appreciated!

My old shop teacher taught me the wire trick with soap and water, i still have the picture 13 years later cause i thought it was the coolest thing ever. Really taught me things are not always what they seem visually. Matter of fact, ive been blessed with some good teachers like yourself in my career to make me as good as i am. Love passing this knowledge along to the next generation

Love those old trucks as well. 👍

It’s gotta be liquid water, the dry water gets sticky

You make me proud to have been a Driveability technician man.

And that’s the exact reason why I love my 02 ZR2 Blazer so much, easy to work on, dependable and $70 bucks a month for insurance lol.

Good looking OBS Blazer!

These guys do a really job 👍

Started working in a ag equipment, big rig repair shop a little over a month ago. Even though I was hired for my modern diag knowledge and willingness to become better, the old stuff is soooooo nice to work on. Even the clapped out Mack dump truck I just did a clutch on that was a nightmare. Give me those older trucks/ equipment any day.

Dave you are the best .one of the few good guys left

We use to wait till dark.

Timing is the fifth thing you need. Just putting it for whomevers new to fixing motors

The old stuff is so much easier to work on. Love the old square bodies.

Beautiful K5 blazer was beautiful back in the day with a removable camper tops.

“These old motors need 3 things…” 1. Compression 2. Spark 3. Air 3.1 Fuel 😂

Sounds like 4 things to me, but I digress.

Wish I could send my car to you get I running 110%...your work ethic is top notch 👌

i learned this as a kid when i asked my dad’s friend who was a master mechanic for the local air force he worked on everything from the old dodge k cars to trains and the fire crash trucks so lots of experience anyway i asked him what the spray bottle of water was used for that was hanging of his work bench and he told me it’s a good tool for finding misfires and he showed me it was a very interesting thing to learn as a younger kid

Gotta have "good equal umph" 😅

Did he say get some liquid water?

Very sharp looking truck. Its impressive how quiet the engineers got those old engines.

Years ago at a bus garage owned by the school district, they had a series of engine failures over period of two years. Long story short, I found out that number five was firing number seven and that was the reason they were breaking cranks and cracking pistons. They were remanufactured engines from a local engine builder. He knew what the problem was but he never told them. So once I found out what the issue was and they changed the wires on most of the engines the engine problem went away. Lots more to the story but you have the meat of it.

Where can I purchase Liquid water.

this is so cool now I know why my coil wires need to be replaced instead of just replacing them

I bought a Blazer years ago. It was missing really bad. The car lot gave me a great deal to get it off of their lot. I got under the hood the next morning. I took the "custom" breather off and she purred like new. The breather was resting on the distributor cap. That was the best feeling.

My favorite stuff to work on is old stuff, less things to go wrong and WAYYY more room to work 😊

Yep, the manager at the first shop i worked at, taught me this trick. Thanks for the memory

Man I wish I could afford to have you guys build my 09 duramax !!! Yall do amazing work !!! Thank you for all of the great tips and help !!!

Dave is a awesome mechanic very personable and professional I can't wait till they make a show about his shop

I just learned a thing or two I'm 17 and own a 1985 chevy 305 and I do love the extra room to sit

1989 K-Blazer. Bought one new in Austin and put 235,000 miles on it before I had to get a four door (Yukon) for the family. Great truck. Wish they still made them.

Man the old stuff was easy. Easy money fun to work on just all around good.

Why do old cars look so beautiful, I was around when this thing was new, and at the time it was nothing special, now it's beautiful. A lot of newer cars look great too, especially percentage wise.

I love the K5 Blazers and full size Ford Broncos.

I love those blazers, nice matco truck in the back too.

Bro just learned me something . Holy cow I’ve never seen that before .

Most BEAUTIFUL Truck in the DACC shorts library!😍👍👍😎

POINTS!! I was beginning to think I was the only one left that knew what a set of points were!

I got an 89 k5. I love older cars as well. Im happy when one rolls into our shop and i get the ticket

Damn, great looking blazer. We had one just like it growing up, I loved that thing!

K5 blazers are my Favorite!!! Sale for big money now.. use to be 3,500$ all day long...

Gas motors need 3 things: 1. Umph 2. Spark 3. Air 4. Fuel Good one Dave! 😆

Just make sure it’s top dead center n check for vacuum leaks, plugs you’ll hear them, gas you’ll hear it, idk I’ve learned with older trucks that just noticing a back fire or odd rumble was enough for me to know what’s goin on, . Love your tips, soapy water saves lives

I love these 89-91 blazers!❤ wish I could find one that clean 🎉

My first car was a 71 Charger 440. I had to let it go because I couldn't afford the gas and weekly repairs. I got an 82 Plymouth Horizon 2.2. Half the cylinders, a fraction of the HP and four times the wires and hoses. I still liked it, it just wasn't the same.

That blazer is beautiful.

Beautiful K5. Keep them rolling

Cool! You can also put a blanket over the hood to look for the short in the dark.. never seen the soapy water trick before. 👍

Another word of advice when working on older vehicles. Before you pull out any of the Fancy Nancy tools any of the testing devices whether it's an electronic or compression testing devices. Yes I am only 20 but I've dealt with two generations of mechanics in 1994 f250. And the things that have been unplugged for certain reasons. Is just astonishing and sometimes that can be part of your problem and plugging those back in can help you make the correct diagnosing of what's wrong with the engine. On top of that with older vehicles turn to be owned by older people that like to work on their own vehicles when it comes to simple things. Nate passed away vehicle gets passed down to the next generation. They thought they were able to pay enough attention to grandpa doing it turns out they got cylinder one spark plug wire on cylinder 5 and cylinders 5 spark plug wires on cylinder one. Or when they tried to replace the points and the cat and they got the wires mixed up.

Also… Love your shop… I WISH You were closer to me!!!

In the 70s, we always did a compression test with tune ups. It might get more work for you.

Fun fact: our jet skis run perfect at the lake but sometimes they run terrible as soon as you get to the ocean. Take the hood off after sunset and the salt water will show you lightning all over the place under the hood. We use self vulcanizing tape to insulate it if we are desperate but fresh coils would be the way to go to get fresh plug wires.

That’s a cool trick I’ve never seen, soapy water to check for bad plug wires, I’m gonna have to use that trick!

Back when i was a young lad. I was driving my vw powered by a vr6 in the snow when it started to misfire. I pulled over opened the hood and from what i know now is my coil pack, was coming hair line white flashes. I asked myself, what the heck is that? I went in with my index finger to find out that it was electricity. Oh i felt those shocks in every one of my holes.

What a great looking truck!

Soapy water is an unsung hero in troubleshooting a few things.

Always good to see the old tricks being used to find a bad wire

Learnd that trick from an old mechanic about 50yrs ago except we used salt in the water because the salt conducts electricity and lights up bright.

We learned this in shop class in high school over 30 years ago

Engine Dave, motors are electric. Love the content, your shop, and everything you do. I’d be honored to work for you some day.

You can tell that tool truck is there only one guy messing around in the shop. The rest are paying weekly bill. Great tip with soapy water and compression test to make sure problem will be fixed......

Been doing that for years works great when it's on Dyno have a blessed day today 🙏
