Never Do THIS When Cleaning Your Engine Bay! Do THIS Instead

Detailers, especially on YouTube, love to deep clean engine bays because they’re always so dirty and show a huge difference when cleaned. They pressure wash rinse, soak it in foam degreaser then hit it with another pressure wash. My gut instinct was that it was excessive especially in newer cars with so many sensitive electrical parts/connections, thank you for making this video Ahmed.

Great video as always I wash my engine couple times a year. I’m in salt country. I regularly spray silicone spray on my wires and I also use silicone paste on and around connectors to keep water off and keeps wires soft and copper wires from going green. Friend of mine bought tundra same time I did and his wires started to turn green while mine stayed copper. Been doing this since 1983.

Another informative video dripping with common sense. As a pro bike mechanic we faced similar cleaning issues with getting water into bearings (hubs, headsets, bottom brackets), the trick is to use dawn dish soap, soft sponge and a very light spray. I finish drying bike with a leaf blower front the front and back (preventing water entry into bearings and frame).

I have a 2020 Tacoma and when I clean my engine bay, I don’t use any water at all. I use Chemical Guys “Nonsense” (no water) all purpose cleaner. I spray the cleaner in a small area, clean with a small horse hair brush and then wipe it down with a microfiber towel. Doing it this way takes more time but in the end, I have a clean engine bay without the risk of any water damage whatsoever.

Been pressure washing engine bays in my vehicle for decades. Just be prudent with distance. I kept one truck for 15 years and had zero negative effects. Cant be just luck.

One time I went to a Toyota dealership to pick up some parts and I’ve seen their mobile detailing staff members power washing engine bays in pre owned trade-in cars so I assumed that it was safe enough to spray engine but not the electrical components. Thanks for sharing your wisdom and mechanical knowledge with us 👍.

I use Huggies natural baby wipes and spend a good amount of time cleaning by hand. If it’s good for a baby’s bottom it’s good for my engine bays.

Mr. Car Care Nut, you are a big blessing to car owners. I have always resisted the idea of taking my car for an engine bay wash and I am glad I have never done it. The advices I have received from a few local mechanics have been misleading, one of them even told me that I could wash the engine bay under pressure when the engine is running! I remained skeptical of that advice and am glad I watched this video before attempting any cleaning methods. When it comes to maintainance of my V6 toyota Mr. Car Care Nut's advice becomes cardinal rules. Thank you Mr. Car Care Nut for always educating us on how to maintain our cars. May God bless you abundantly.

I just don't clean mine.

Something worth remembering from the carpentry trade: water will travel upwards between two surfaces - against gravity. If I remember correctly it was referred to as the "phenonemon of capillary action". We had to know this when making casement windows to determine the gap between the sash and frame, and then create an anti-capillary groove. They were referred to as anti-capillary grooves on the drawings that went back decades and decades. So different from 'drips'. So the point being that when AMD says water will find its way into areas, this is how I expect it will do it. If water finds a way with wood, then I expect it will have an easier time with metal and plastic. The last mobile mechanic I employed just left the hood open in the slashing rain, and I never went back to him. Shows how rare a mechanic AMD is that he brings this up. Greatly appreciate the videos as always.

I was a school teacher for 25 years. Fifteen of those years I drove a bus. During those years, I bought a high mileage 2004 Tundra with 220,000 miles on it, and drove it for years. It sat more days than it was driven, and I typically only put 8,000-10,000 miles a year on it. One day I discovered some animal collected all types of things (leaves, pine straw, part of a some red filter foam type of material, and other trash) and carried this soft fuzzy stuff under my intake to make a nest on top of my 4.7L V7 right by the starter. I found out because I saw smoke coming out of my hood. I pulled over and fortunately we did not have a fire could not reach the debris by hand. Using some wire, I got about half of it out, but could not get it all. I washed it out...and hoped I wasn't going to have starter issues. Fortunately, we had no issues. After retiring, I got myself a 2015 Tundra and gave my old one to my son. It now has 367,000 miles on it and still runs great.

Thanks for another top professional video AMD! So thankful for the extra peace of mind you bring! Continued Blessings to you, your family and business!!! 😇

Dude is a lightning-fast engine bay cleaner!

Wow. Finally, you made this video! Thank you, Ahmed.

I really appreciate your detailed explanations and subjects that are not discussed often. I appreciate your expertise in this area and thank you for your videos!

Thanks again for a great informative video. I've had my new to me 2022 Prius LE for three months now. Thankfully I've never spayed the engine bay with water. I used to spray down my old car's engine bay from time to time (a Kia Soul), but did it gently. But seeing you demonstrate how I should keep my already spotless Prius's engine bay clean confirmed my thoughts on this. Thanks again! Your channel is a top favorite of mine.

Good Looking out Boss;! Thanks for sharing your thoughts and videos. Every time I’m going to do some things to my new Tacoma, I always say let’s see what the car care nut has to say about it. I have learned so much from you thanks 🙏 again!!

I’m not surprised some people don’t even have common sense after showing you the WHY and still going against it because they been doing it there way for 50 years,lol. Thank you AMD for this and all your videos, long time subscriber here.I have learned to do my own maintenance on my car because of you and can’t thank you enough. I’m no means A mechanic but have learned so much through your videos. I just purchased new Toyota and now know how to keep engine clean. Keep up the good work and god bless you too.

This video gives me vibes of a physician or dentist who is realistic and caring. Nothing alarming. Just explains general info and why we do the things we do. Nice video!

Nice. My older cars are old but I keep them clean, in and out and under the hood. And I feel good about how they look.
