I remember I used to watch your videos and think, "I don't even have a toyota " now my first toyota is a 4runner. Thank you for making these educational videos!

Good thing they brought it to you, the Toyota dealer probably would have said you need a new engine, engine is toast.

Engine was hydro locked and still didn’t get damaged! Gotta love the Toyota 4.0 V6!

Just changed my spark plugs, although I knew 100% I re-attached that hose, I still went out and double checked. One thing I think is very important as a DIY'er, is to make yourself a checklist of every step you must complete, and triple check it as you go. It doesn't matter how familiar you may feel about a task, working out in the cold or heat will make you forget stuff. By running a checklist, you reduce the chance of this happening.

He perfectly explained why I will never step foot in a Toyota service center again, unless its to pick up my purchased parts.

You are a natural, born teacher, the way you explain things gets through to pretty much everybody

[horsepower]

That’s why you either find a good mechanic you trust or learn to work on your car! Ever since I started working on my car I’ve had zero issues but I still wish I lived close to Car Care Nut he is a legend!

We had an older Ford ranger with the typically Rock solid Lima 2.3 engine. One day my son was driving it in freezing rain, it slid on the ice and gently turned sideways into a ditch. The ground was so soft there was only minor damage to the fender. Fortunately, he shut the engine off right away. We took it to a shop that had a good reputation but that we had not used. A technician there told us unfortunately the engine had hydrolocked. However, he said he would offer us $350 for the truck. That triggered my suspicions. We took the truck to a body shop recommended to us and the mechanic there said the story was BS. He cleaned it up, put some marvel miracle oil in it and fired it up. It shot a little coolant out the exhaust and ran fine after that. We put another 60, 000 mi on it and sold it you're a very happy young man. The moral is if a technician pronounces your vehicle dead but then makes a lowball offer for it get it somewhere else as fast as you can.

100% true. An old timer told me this a long time ago. He said short trips will kill your engine. You can smell your dip stick and if you smell gas, you are killing the engine. Really good information as always. Im still enjoying my 2003 gmc envoy because of knowledge like this.

[mikemike]

Been working for Toyota for over 10 years now, first time I’ve seen/heard of this happening to these 4Runners. This is definitely some very useful info. Thank you for posting this!

[coltonworkman]

I don’t even own any Toyota vehicle but I love to watch your videos and listen to your knowledge of Toyota products thanks for your hard work and dedication

[truckerrickakamanowar]

A testament to how tough and well made those 4 litres are. One of the best engines Toyota has ever made imo.

Last year I bought my 2023 Toyota 4Runner brand new. My first new car since 1989. Yup. And my first ever Toyota. I’m hoping it’s my last car and I love it.

I did this with a the first car I bought, a 97 Civic. I did exactly what you said, I would started it to move it out the way of my roommate to get out of the driveway then later start it to put it back. Luckily on the third startup it triggered the check engine light. I don't remember exactly what the code was but I think it was a rich code. The service advisor said exactly what you said, never start it and shut it off because it will dump too much fuel in the engine. He said just driving around the block and back would be good enough to burn off the excess fuel.

Every time (almost) AMD works on a car that another mechanic has worked on, he discovers problems such as missing clamps, wrong parts, loose or mis-routed hoses / wires etc. Sometimes they aren't critical but just bad practice or a mechanic unfamiliar with the car etc., but sometimes it is. Even though I DIY on my cars, I would not leave hoses loose, screws/bolts out etc. I did learn something new here and a very critical item, that too. You are a true gift to Toyota owners and to car owners in general.

[Treetopflyer]

I had to run out to my 4R to check that hose 🤦🏻‍♂️
I bet I’m not the only one haha😁

[chromeplatedcowboy]

Honest and SKILLED mechanics and repair shops are a Godsend..most rural areas do not have a place like this.

[ajchiappetta]

I own a repair shop specializing in bmw, Rolls and other exotics and I drive a 2024 4Runner, I bought a TRD ORP and have fallen in love with with.

[jamram]

Rookie mistake that should never occur. My father, a gasoline/diesel technician for over three decades, always taught me to return and check and recheck the work performed. This was a very happy ending for this vehicle owner. Thank you AMD….

[ChrisJDee]

Not too many things would put a 4Runner engine at risk, so it's definitely worth paying attention. Great video.
