Never do This when cleaning engine bays! These are the common issues that happen after cleaning and\or washing an engine bay that I see after washing an engine bay.
Folks you've been asking for this video for a long time and I hope this video delivers what you've been asking for. I am not a car detail professional however as a mechanic I see the common mistakes that cause issues with detailing an engine bay.

Detailers, especially on RUclips, 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.
Good to know. I'm in southern California and had to watch RUclips videos to see the damage that salt does. Unbelievable till I actually saw it.
Nice to know others do the same thing. Friends think I'm weird for using silicone/dielectric grease to protect the electrical contacts.
I clean my engine by hand, water and bucket a small brush. Then I buff the whole thing with WD40 with a rag till dry. Last 6 months.
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).
Unsealed bearings and even sealed mechanisms should be illegal. It amazes me how many bikes that are $1500+ still have unsealed hubs. 🙄
Even with sealed bearings on a non-steel bike?
water in engine bay, motorcycle, bike, is all madness. just wipe it off.
minus engine bay, that one needs nothing. leave your esthetics for visible parts.
@@kovie9162 Yup. It is best practice.
@@Evom777 Yes. That is ridiculous.
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.
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-drip groove.
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.
Wood wicks as it's permeable. Metal is not. Basic understanding of materials.
not being a dick/capillary attraction
No that's not what it is. I think you're referring to is water being absorbed by wood. What I'm refering to is two non-permeable surfaces (such as glass or painted wood) that are barely touching each other. So if you've got a electrical plug facing upwards into the socket, the water will find its way between the two and it wont drop down with gravity. Or with electrical wire it will go horizontally before it goes straight down if the wire is horizontal for example.
That's why a traditional window should have a groove between the sash and the frame, because it should only have a penny gap (1/16" or so) after its been painted. But nobody ever did it, and typically they didn't have a penny gap so it didn't always matter. @@jahmanborneo1343
@@jahmanborneo1343 it wicks because water is attracted to itself, not because of the properties of the adjacent material.
@@jahmanborneo1343 Not being a dick, materials don't matter, it's a combination of liquid surface tension and the adhesive forces in play. Basic understanding of capillary action...
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!
I always use diesel as a degreaser, do cover fuse box, battery and alternator with a grocery bag and on a spray washer I never push actual trigger for more pressure, just spray it off, keep hood open for a good 15 minutes, carefully wipe out the area with microfiber towel, lastly I use 303 plastic / rubber protector spray as a detailing. I drive my car as delivery as well as for personal use about 35K a year, any weather, keep engine bay clean is a must for me.... Great vid, thanks for sharing 👍
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!!! 😇
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.
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 👍.
The dealerships usually contract 3rd party detailers to do their jobs. The detailer will charge a certain amount like $500 for example & the dealership charges the customer $1100.
I've seen toyota detailer power wash the inside of car doors 😂
@@goldentrichomeshydro4260detailers will often clean out the door jambs using a pressure washer. They use a low angle tip to limit the amount of water getting into the interior.
@balabay77 Worked for Toyota in the early 90's which i jet washed Toyota engines & the area manager caught me TWICE! He did warn me the first time. Never had any issues,i didn't go overboard jetting it,i just made sure the chemical was pretty strong but not overly strong/powerful....a decent scrub prior to jetting is what i did.no comebacks thou..
They're hiding the oil leak
You are 100% correct when it comes to your explanation of cleaning your engine, it's science and application
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.
Wow. Finally, you made this video!
Thank you, Ahmed.
Hi, AMD!
Thank you for your professionalism!
I'm in fond of your videos and thankful for answering my emailed question.
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 used to work in a garage but as a car painter, the mechanics always told us to let the engine run if it was a diesel while washing it and not spray directly on certain parts it was almost a decade ago and only did it once or twice but I think the reason is that if you didn't the engine might not want to start after and maybe because if there's some water that goes where it shouldn't the heat will dry it.
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!
I’ve never used water inside my engine compartments. I’ve used either windex or simple green. They are both great cleaners and degreasers without fuss. With all of the electronics and connectors, you have to be conscious of your cleaning methods. His points are well headed.
Great video. I use to detail cars and luckily never had any issues. Always used a degreaser and pressure washer at a distance. Let the degreaser do the work. But nowadays on my personal vehicles I just try to upkeep the cleanliness so it isn't a big deal.
Thanks on the info on touchscreen infotainment systems. I didn't know they could be damaged with certain cleaners. Been using 409 but will definitely be getting touchscreen cleaners.
Thanks, excellent info. Working with electronin equipment since the early '70s, MANY intermittent problems were caused by connectors. We old timers could go to the coin op car wash and spend 25 cents on a shiny engine. Those days are long gone. Compressed air is your friend.
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.
We’ve been waiting for this once since you announced it, awesome man, so great!
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 a huge fan! I'm 71 and like to be as hands-on as possible in life. I have 2024 Camry Hybrid. May I suggest doing a video where you suggest/instruct non-car people - those of us who can't get underneath their cars - how to do the simpler tasks?
Car detailer is a super tip to clean the engine covers. Thanks 🇨🇦👍👍
So appreciate your knowledge and attention to detail in your videos. I'm having trouble finding detailed service/maintenance schedule for my 2018 RAV4 XLE. Currently just over 50k miles and I'm aiming for 300k. Seeking greater details on what needs to be checked, changed, serviced, replaced. Thanks
So amazed how professional you are , we’re lacking people like you in this profession (even in France 😂).
Those videos are so informative, please keep on doing this. Thanks for the sharing
@@phillipbanes5484 sorry my english is not fluent. We have some good mecahnics there but also some really bad... like everywhere i suppose ^^
even in France….well that just changes EVERYTHING I used to think about France. From this ONE comment. Now I do not think that France is perfect, or that EVERYONE is professional. That’s crazy how I used to think that every single one of you are painters or poets or lovers or skunks..Now I’m just all confused about the fact that France and its people might actually just be as normal as a lot of other people, and not snobby, inflated ego, oblivious, crass, body odor having, pubic hair flaunting croissant eaters. Absolutely crazy. Thanks for the perspective.
@@phonkyfeel1 as i said before, my english is not fluent, i didn't mean to say thing this way. Of course every country is not perfect....It is crasy how people are overthinking or reacting.
@@phillipbanes5484 as i said i didin't mean that at all. i understand your point and i ll be carefull on it, but please don't assum that all french are arrogant, that's a bit racist...
@@phillipbanes5484 got it , thanks for your advice. i'll be carefull on the way i express myself in english. Sadly i think i did a msitake an used some loan traduction that cause this issue
I been waiting for this video for so long. Thanks so much! blessings
Nice to present a clean engine bay to a mechanic because the mechanic will appreciate you providing a clean engine to work on and it also shows that you have some respect to the person working on your car. That in turn is more likely to give you a mechanic that is happier to work on your car.
Thank you AMD, God bless you and your family.
Thanks for the tips on this. I only wipe when cleaning the engine bay. I will use the quick detailer next time. I love the results. For the touch screen I use a microfiber rag damped with water.
Of course it nice to see when your mechanic cleaned your engine bay little bit. He had to replace some part , but he also cleaned, so for me this means that he cares. I live in Germany , and I have visited many shops with my previous German car , and no one ever cleaned anything.
The personal cleaning demonstration was very helpful - common sense prevails.
Mr TCCN is the MAN, the MYTH, the CAR CARE LEGEND!!! Thank you! 👍❤
I’m glad I watched this video. I was thinking of cleaning the engine bay soon. Just ordered the body cleaner and will do this. Seems very simple!
Thanks for clarifying this! I always see detailers using a pressure washer on the engine bay and they always say how safe it is! The problem is that they are NOT mechanics and the damage they MAY do wont necessarily be seen for many years. Wash by hand, and take your time...
While it may seem fast to just rinse down everything with pressure washer, in reality, it takes more time to dry everything. I learned over the years to just use a leaf blower once a month and a simple wipe down with a slightly damp shop towel if necessary. Truth be said, when the plastic covers are clean, that already satisfies each one's itch. At the end of the day, no one is going to look at your engine bay everyday.
@@michesbianan 💯
It was not that big of a deal before fuel injection and a tone of electric parts. We always pressure washed our engine while running but right after wiper it down. Cars didn’t last nearly as long as they do now. In New England we always had to replace wires but they where a-lot simpler
@@christopherjoyce9788 Right, older cars really didn't have many electronics at all, and a little water wouldn't hurt a cast iron engine with good ol' carbs! I miss my 78 Cutlass! 😆
More useful advice, as expected from this channel. Thank you
Agree 100% I couldn't say this any better. Very delicate parts in your engine compartment.
Really informative. Thanks for the video and especially talking about hybrids as well.
thank you for always providing sound and very informative advice!
Thanks for another video with good tips. I have always only used a rag and water without a high-pressure washer. Did it regularly. Will never be a problem. Ps: Work on some older cars now and then, so that we with old cars feel a bit at home in the videos :) :) I have two that I watch the most. The car care nut and scotty kilmer. Lots of good tips.
This is gold. I will not be offering engine “detailing” as a service and honestly, I think it will win them over when I explain why using the information you provided. Thank you for this informative video.
I've cleaned a couple thousand cars, and honestly, just a 20-30 second power wash (avoiding alternator and connectors), dry it up, then spray a water-based interior dressing and the customer will be very happy. And it'll take less than 10 minutes.
I'm incredibly grateful for the info you shared! I've used a pressure washer twice on the engine bay of my 2018 Camry XSE V6 since I bought it. Maintenance washes involve wiping down and blowing dust away with compressed air, and so far, no issues at all!
Thanks AMD. Great job. Good info. Excellent advice. God bless. Happy trails.
thank you so much for educating us about car caring
Appreciate the tips AMD. Happy Thanksgiving! Many people, including myself, are grateful for your channel!
Another excellent, helpful video- thank you CCN!
Thanks for sharing the true way to clean the engine bay..
This is a very helpful video. I appreciate all the details that you did. The example of using body cleaner or waterless car wash spray is genius!
Helpful and informative. I learned many new things. Thank you. Have a wonderful day!
Thank you! I've been looking forward to this one.
Thank you sir , I was going to ask you to do a video on this the other day. God bless
Excellent advice! Clean your engine compartment exactly the way he showed us and if anything malfunctions you will have a clean conscience knowing you didn’t cause any problems. Clean the exterior and interior too your heart’s content but if it ain’t broke don’t fix it! Leave the car hood closed!!!
I have been waiting for this video for so long. Thanks so much.
I had rat poop on my 2016 Honda Pilot engine cover, and removed the cover and washed it in my bathroom tube. I live in NYC, the Bronx, I guess I am going to charge them rent! LOL.
One thing I do is just use a swiffer wand every few months to remove dust in my relatively clean engine bay. It is pretty good at reaching into crevices or hard to reach places. So far I haven’t needed to use any liquids to clean it since I bought the vehicle 4 years ago.
Good teaching. Thank you and God bless you 🙏!!!
Great info Plain & very simple!
Nice job!
I always enjoy your videos. Thank you for taking the time to make great videos.
thank you so much for the information.
thank you for this video AMD.
just in time. i am really looking for a video on how to clean/maintain the engine bay. you are right, 30 minutes is enough once a month to maintain the cleanliness instead of letting it sit for 6 months.
God bless you.
I love the way you present your very informative videos. It would be awesome if you did online classes. If you ever do then you have your first student right here.😊
Outstanding video and presentation
I know mechanics always say this but I've been doing it since 1986😅
It hasn't taken me very long, watching & listening to AMD. Always follow his advice.
Thank you for your video👏👏Very professional and detail👍
Thanks!, I like to clean engine every oil change and/or filters replacement and as you mentioned, when cleaning I can check for possible leaks, rust, to tight loose caps and/or hoses, etc.
AWESOME SHOW. THANKS, GOD BLESS. 😇
Great tips...better to maintain regular cleaning than not and then having major cleanup.
Thank you for the great, informative videos! I am a big Toyota and Honda fan. I operate a car wash and attempt to provide guidance to customers when i see them preparing to wash their engine bays. The water pressure at the exit of our pumps is 1450 psi! In bay, the water pressure at the tip is about 1300 psi, high enough to cut a finger off. We also use professional strength Dawn to degrease our bays. It works great and is not aggressive on paint.
Thanks for the tips. I hadn't thought about covering the alternator. Some cars (I'm thinking of my Dodge product) has the ECM exposed. I cover that before cleaning. As MarzNet256 suggested, I use my small (Worx) battery leaf blower. It's useful for blowing leaves and dust away. When I need to rinse engine cleaner off, I'll use a light mist spray from the hose, then use the blower to dry up most of the water. I don't use my compressor as that might drive water into connectors.
I am very conscious of my 4Runner’s condition, and first use a very soft dust pan brush to get most of the dust off my engine components, and then move on to other means as necessary. Works great! Thx so much for your great videos, and for your spiritual sign off 😊
Helpful information, good job
On my older 1995 Dakota 5.2 Sport I use what I learned from a neighbor on his 5.0 mid production Mustang with it’s brand new looking engine bay. A hand spray down with Original 409 cleaner, wait ten minutes, then garden hose spray gun on spray setting. Because of all the connectors and deep spark plug tubes in my 2021 Tacoma Sport TRD I will be subscribing to your hand spray detailer micro fiber wipe down instead. Good video. Thanks.
I agree… I maintained my wife’s 2018 Camry from new and almost 6 years later the engine bay looks like new
2018 Camry also. Early summer i use dish soap with a lot of water at low volume to remove salt. Then run the car to heat up the engine . Then wet towel to clean the top covers and painted areas. Works great .
Amazing advice that should be taken seriously! Thank you very much for all your advice. The problem is that the people who need it the most don't listen to channels like this one, "which is the best."
I’ll use some simple green/purple power, rinse with wide spray of water, then compressed air. I’ve never had an issue, but I generally only do this annually. Engine bay looks clean helping to spot any leaks.
I’ve seen many cars where it’s so dirty, you can’t even read brake/washer fluid levels.
We detail in our automotive shop after a car after a repair that involved an oil leak. We dilute Purple power with water and a brush to agitate the oily grime. We follow with compressed air and a wipe down. I apply tire shine on the plastic and then a wipe down to remove the extra residue. We avoid alternators and ECM/PCM. It can take 1-2 hours but we want to the customer to notice the difference in the finished product. We send them BEFORE and AFTER photos of all of our repairs
@@jamram9924 I'm a bit late to the video... only a few minutes in... but was hoping this would be addressed. I need to do some de-greasing and cleaning on my high mileage car to help see if I have an oil or other fluid leak. (Both now and preventative in the future)
@@fricky172 sometimes I’ll use a pump bottle with very hot water and degreaser. I apply it directly to the areas where the oil is present. If the oil turned into greasy dirt, you may find yourself using a stiff wire brush or putty knife to remove the thick encrusted oily dirt. I’ll use a power washer in areas like the engine block, transmission and engine oil pan to do a final wash and rinse.
Thx for the tips. On the infotainment screen. What works for me is very light mist of distilled water and a microfiber cloth to "gently clean the screen" Never use Windex or any alcohol based cleaners on infotainment screens. I'm going to try the no rinse car was for my engine bay. I've always just wiped it down but l Like your suggestion and demonstration.
I’ve been waiting for this!
More Wise advice!! I love all of your videos
Thank you for the great information. I wish I lived in your area, our dealer has never done this after service on the engine bay. You must be working for a very reputable dealership.
Thanks AMD, awesome video.
Happy Thanksgiving! Thank you for all your tips and advice, you are a blessing to all of us.
Excellent video...very timely and valuable advice.
I've been waiting for this!!!
This was great useful information. Thank you!
I had my engine bay cleaned by an expert and it looks amazing
Nice to know that I've been doing most of the right things all along. :)
This video should definitely be one of the most important videos on your channel.
Excellent informative vid bud!
I see that MR2 in the back!!! love seeing those makes me want to get one alongside my NA miata
Wow another brand new video I can't tell you how helpful these are for those of us who want to own our Toyotas for a lifetime!
totally agree with you, i just spray a towel with a general cleaner(quick detail spray) and wipe everything down, works great and zero water so no worries.
Me too. I can spend hours on the initial cleaning, but monthly, bi-monthly, it's just a dust wipe down. I love old cars.
Great tips👍. The detailer product use is a good one ☝️. Bottom line, less (water pressure) is more…
Thank you, Ahmed. I should be more careful when the engine is hot, not to wash it with cold sprayer at the self serve drive through washes. It's so tempting to get it super clean like you said, "not necessary" and could damage components like the alternator. Much appreciated your video is really helpful. May the lord keep YOU and bless you. Have a nice day!
I just wipe things off with shop towels type paper towels. I use armor all cleaner but that's obviously not the only one that one can use... A damp (water) paint brush cleans areas that are hard to get at. Good demo.
Some vehicles are designed/built better than others in terms of keeping stuff out of the engine bay, so it doesn't get dirty/soiled much in the first place at all. My 2022 CX-30 is almost 2 years old now & the engine bay still looks brand new minus a very light coat of dust that I finally wiped off last month without much effort. The Corolla Cross (& regular Corolla) has two giant/open hood gaps above the headlights from the factory with no seal & which allows all sorts of rain/water, dirt, grime & debris into the engine bay. My friend's one year old Corolla Cross looks super dirty/grimy already inside the engine bay & my 2020 Corolla sedan had the same issue. Not sure what Toyota was thinking (other than cutting costs) with those large hood gaps & no seals/weather-liners for U.S. version models on these vehicles (some other global markets did receive the seals/weather-stripping in those areas). Tacky, tacky - and makes you wonder where else they cut little corners to increase profits.
I normally go over mine with Tub 'O Towel wipes but I'm going to try some waterless car wash soap and microfiber towels next.
I, once, saw a list of the Top Ten most un-trustworthy professions and it included the "why" for each one. Not surprisingly, auto-mechanics made that list. I am certain that, if names had been found there....yours would not make it to the list at all. You are convincing because you are such a professional----AND so trustworthy. I would imagine that you have a trail of customers who are so relieved to know that they chose you as their mechanic. I sure would be. Your videos are both educational and entertaining. Even if I see one that has nothing to do with any car-issue I have, I still watch them because you so seamlessly explain and demonstrate and I learn many new ideas. I always look forward to your next video.
You’re a likable guy! Great channel!
I’ll clean the engine bay maybe once a year but more importantly, I replace fasteners that are starting to rust. Good information here as always. The engine bay gets dusty and dirty very quickly so I just hand clean with a hand pump sprayer. I like Oil Eater spray. Doesn’t affect metals or plastics. 1:2 dilution. Distllled water.
I suggest using fluid film with a applicator every season. Eventually it builds up thick and you just have to touch up once in a while. People think it’s just for underneath but you can spray it anywhere and all over anything. It stops rust and makes the plastic shiny.
I do the same with fasteners! I replace any that are starting to rust. I also keep the peppermint cans fastened in the engine bay also….They keep the mice, rats and squirrels from Chewing wires. The peppermint works great.
@@markm0000 Coating an engine bay in oil, what could go wrong lmao
@@ADUSN The coating just boils off areas that get hot. The problem is when you have a lot of oil dripping out the valve covers right onto the exhaust while the car is driving up a hill with high EGTs. That’s when it becomes a fire hazard and the oil combusts.
@@ADUSN Oil temps reach 250f max? Set your oven at that temp and put a pan full of thin cooking oil in there. It will not catch on fire, it just boils off. Same thing here.
