You reminded me of a story I heard. A guy got a flat tire outside the yard of a mental institute. As he was putting on his spare tire he dropped all the lug nuts down the storm drain. He let out a loud exclamation, with curses, as he watched the lug nuts disappear. An inmate who was inside the fence and happened to be watching the mishap, yelled at the driver; "take one of the lug nuts off each of the other three wheels of your car and you'll be able to get to a parts store on three lug nuts." The driver was perplexed at such good advice coming from the insane asylum inmate and said; "that's a great idea, I thought you people were supposed to be crazy", to which the inmate responded; "well we might be crazy but we're not stupid."

My Dad was a mechanic and his name was Scotty ❤️ He always told me to "Pay attention because I'm not going to be around forever" I wish I paid attention...I miss him 💔

Scotty, I am a 63 year old and have been a fix myself car guy. (Hotroder) my whole life. And you are one smart cookie. Thank you for taking the time to teach an old dog new tricks.

We need more people like Scotty. An expert in his field willing to help people instead of trying to take every last dollar out of your pocket.

I love Scotty...I am an experienced mechanic, but I have learned so much from him. I watch almost every video he creates.

Great info on the battery jumping. It's worth mentioning that ALWAYS connect the red/positive to the terminal FIRST then the black/neg to a part of the car. This minimizes sparking to virtually nothing. Also, while you mentioned that battery explosions/fires are rare, they can and DO happen even with today's batteries. Always clear the air around the battery, (just fan it), before connecting to a terminal. If you've ever seen a battery explode, it will ruin your day and possibly your car, eyes, face, skin, and so on...

When I was a teenager my battery died in my car, I was in the process of removing it and as soon as I started removing the negative cable my battery blew up in my face, the only thing that saved my sight was my uncle grabbed the water hose and flushed my eyes out. I was blinded for three months. I live with nerve damage now. Be careful removing dead batteries.

I am a 79 year old and just burned up my 2000 Lincoln Town Car !

Next up will be electric cars that have 'sealed for life' drive systems. I really wouldn't want the change the battery on one of those ! .. Thanks (from the UK), for your entertaining presentation Scotty.. P.S. Living free is also getting difficult !

What would we do without this guy ? Got to Love him.

My 2011 Camaro Convertible had the AGM battery and there was a reason it was ordered like a race car with only the suspension and drivetrain upgrades! Even stripped down there are tons of electronics, but GM doesn't make life harder. My '08 Caddy came with a lead acid but I went back with the glass mat, and I did that battery swap myself, but quickly, and my battery wasn't dead dead.

My 12yo Sonic LS sans turbo and automatic has relatively simple electronics, even a proper top post battery. Incredible lighting system never allows a dead battery. I've only changed rubber parts like wipers, tires and coolant hoses. For a noise I replaced the serpentine, but the tensioner was the cause. Saved the original belt, it's still serviceable. Original timing belt is like new, no cracks or crumbling of the teeth. Tensioner or idler will fail first, so will change it all soon. Original Freon, brakes, clutch, and the only engine bolt turned is the oil pan plug. No seeping or burning, oil stays full between changes. Simple is the best of every brand.

One of the young guys in the shop I used to work at was undoing the positive lead from a battery and his wrench touched the negative pole - the battery went bang and he got covered in battery acid. 15 mins in the shower and a trip to the emergency room to get checked out, but luckily no lasting damage to him or the car. Ever since then, I've always thrown a rag over any uncovered battery poles.

A tip that might save your life: The two metal tubes on the headrest are designed to be able to shatter a window in an emergency!

Scotty, you can help a lot of people with older or high mileage front wheel drive cars if you do a video warning them to be sure to also >change the small heater hoses that are not visible behind the engine! My 2015 Sedona lost all of the coolant in the radiator on a long trip and overheated damaging the head. Even I was making regular under the hood checks, I didn't know that the coolant was low because the system didn't pull a vacuum. Resivior was still full even when this happened! $7,000 repair!

Honestly Scotty, love your work. Worked for BMW, not anymore though, now gone indie. I learned to simple charge all batteries on AGM setting. AGM setting is lower amps than "regular" setting. Won't wear out lithium batteries either. Save myself a lot of time at work, forget trying to decipher what kind of battery I'm charging. Won't blow up a lead acid, perfect for AGM, and if it has a secondary lithium battery for starting, won't kill that either

So the fancy computer controlled charging system can't tell the actual state of the battery and you have to manually tell it that the battery is new. Sounds like just another way to get you to the dealership.

Lord I miss the 50s and 60s. Cars were easy to work on. All you needed was a good shade tree.

I watched one video because I had issues with the serpentine belt.
