How To Clean a Hybrid Engine 

Probably the safest and cleanest engine bay cleaning I have seen so far. Please do a video on the Gen 3 too.

thanks man, But if I may say, use silicone spray instead of WD40. there is no smell and is safe on plastic and rubber.

Very well explained. I have been looking in cleaning my Prius 3 Gen engine bay but wasn’t sure on how to proceed. Now I have a good idea. Thanks

Very good to see that you are environmental conscious about the chemicals leeching into the ground and getting into the oceans. Keep up the good work.

I also like to see a clean engine. I detail mine regularly and have been doing so for 30+ years. I have never used a pressure washer. I don't like the idea of possibly forcing water where it shouldn't be going. (Like into an idler pulley bearing) My cleaning weapons of choice are plain old Gunk engine cleaner where there may be an accumulation of dirt and oil or just grease cutting dish soap mixed with water in a spray bottle and a long bristle paint brush and a parts cleaning brush to scrub into the crevasses. After a good brushing I gently rinse it all down. I do cover my alternator with a plastic grocery bag and foil. I don't worry about covering all the plug in connections that are already pretty waterproof since I'm not blasting with a lot of water pressure. Afterwards I dry it all with compressed air and a long reach blow nozzle. My choice for a new looking finish is Dura Gloss Wet look tire shine. Also spread around with the paint brush. It doesn't stay wet and sticky like most tire dressings.

I've a 2008- 2nd gen-188k mi. and always hesitant to clean for those areas to avoid... Your fine effort here clears alot of that for me! - the brushing and spray of connectors - use of aluminum foil -use of trimshine Thanks Angel!! :-)

That grout brush may be stiff enough to damage some wires or connections. I wonder if a softer bristle brush might be a better choice?

Trim shine looks like back to black in spray form. Cool thanks.

Thank you so much Greg. It helps me a lot. I have a Toyota Camry Hybrid and I want to clean for summer but I didn't know how to clean. Now I do. Love your video clip.

I’m very late but this is by far the safest way to clean engine bay. But I also have 1 question everyone been asking, “the pully thing”. No covers how you can avoid water splashing on that. Other than this, it’s great video. Thank you

I hardly ever even wash the exterior of any car I have, but I have vacuumed the leaves under the hood of my 3rd gen Prius. Seems like that might be a good thing to do before power washing, just to keep organic bits and sand from blowing other places and/or draining down to hidden spots

Wd40 will displace water but it a solvent. It will eat rubber

Now I know why the 2010 Prius we just bought looks brand new under the bonnet. I kept all the engines of my scooters and motorcycles as spotless as I could, it just made sense. That was how I monitored for fluid leaks.

Thanks. Did both of my Prii using your tips.

I'm about to buy my first ever hybrid and it is going to be 2009 Prius for my 160+ daily commute, so I'm going to detail it first, thanks for your videos! P.S. that engine bay turned better than 80% of real detailers have at the end!

I keep my engine pretty clean, I go over it once every other year or so. Personal preference. Not trying to deceive someone when I sell it lol. Just seems lazy to me to let it get all cruddy, it's a big investment, why not take pride in it?

Guys WD-40 is a Silicone lubricant (in a spray form)/ So please be specific and name the alternative to the brand/Item you're suggesting ?

Greg NICE vid. I normally would remove the radiator splash guard, cowel tray and wiper assembly in my prep. ALso I'd use armor all wipes but i like the easier Trim Shine spray. Great alternative ideas to clean the engine bay. Thanks.

But when you power wash you didn’t cover that pulley that you were talking about, didn’t water go inside, especially from 9:57 to 10:07 🥴

WOW, ANGEL YOU DELIVER YOUR Teaching's where I c an understand the Subject. Thank you. There are us who understand when some one who Knows how & Can deliver their Teachings in a CLEAR Controlled, Enthusiastic MANNER. You are TOO COOL. ,, Man I paid attention . THANK YOU. we want your STYLE of TEACHING. eddd

The area around the spark plugs/coils can hold a lot of water and you don't want water getting into your spark plug wells which can cause misfires which will lead to other problems. The seam in the middle between the cowling pieces (just below the windshield) is a known issue on some models allowing water to drip into the spark plug area . Black urethane caulk that resists UV works well to seal the seam. Use an Armor-AlI type product on the connectors and other plastic or use a Silicone spray that states "for use on plastic", wherever you need to lubricate metal along side plastic or rubber. I use Liquid Wrench RV Silicone Spray. Peace.

This is a great video, worldwide they sold over a Million Hybrids, so all Prius should at least counted for a quarter of a million, you sir deserve more views. :)

No need to foil anything in a newer engine. Connectors are made with seals to prevent water from entering. Just don't high pressure wash it directly at the connector. I've washed engines for more than 10 years and never had a problem.

I used a TrimShine equivalent on an 21 years old car and it did magic with tarnished plastic trimming, i want to do the same stuff with my 08 Prius and 12 CT200h, to spruce thing up a notch.

Is it me,, or did you, after admonishing us NOT to get water on that pulley, fail to foil off the pulley and then shoot water all over it?

fantastic!!! I was just thinking about cleaning my prius V engine compartment today! great info thanks!!!!

Nice video, great help for me to detail my Hybrid Thanks !

I've washed my engine without all that stuff on my Gen 2 Prius. I haven't had any problems, but I will watch-out for the belt/pulley. I didn't know about the berings being exposed to getting water in there. I will grab a finger-full of bearing grease and smear it inside that area. (The heat should sink that right in) Thanks.

Can you please make a video for 3rd generation Prius?

Nice video, very thorough! 👍

I would be a little leery of spraying WD-40 on the plastic electrical connectors. A friend of mine back 20 years ago found that spraying WD-40 on Anderson connectors (I believe they were the gray SB-50s) just caused them to fall apart. I wonder if there would be something better than WD-40.

Thanks for an amazing video. You didn't cover the pully with that foil and sprayed water quite generously. I want to know why? Were you able to avoid water going into that pully??

hi thanks for the video. could you also please upload a video regarding the detailing and cleaning of engine bay for prius 2010 models specifically which parts to cover with the foil which wiring components to avoid wetting. thanks

Good workmanship..wish you could make another video purely 3rd Gen Prius hybrid engine clean up

Great Job! Please do a 15-17 Toyota Camry Hybrid when possible. Thank you 🙏

Don't use all purpose it stains. Use Dawn mixed with warm water instead. Skip the wire brush on the wires no need. If possible use a regular hose instead of a high pressure washer. Start engine and let it dry on its own. If done right you don't need to put anything at the end. It'll be nice and clean

what about the bearing? man

Great video

i did it. my car looks new. thank you

If anyone is having a hard time finding those medical sheets to put under the car they are very similar to the puppy training pads you can get at the pet store. I used the puppy pads when replacing my radiator.

I was hoping to see how to clean the later model. I've got Auris 2013 and it looks same as your 2010 Prius. Thanks. Subscribed.

Hi Car Angel, thanks for the video but what about the pulley? It seems like you did not cover it and water got up in there. Should it be wrapped in foil too?

Hi Greg, First, excellent video! I have a 2011 prius (3rd gen) and in your video, you had foiled area just above the ECM without WD40, but you mention also that you should WD40 everywhere that you use a foil. Should I WD40 that ECM area with all the wires? BTW, WD40 is liquid; it seems counter intuitive to spray electrical connections with that since we don't want even our water rinse hitting these area. Is the purpose of the WD40 to clean since you weren't able to do with with the Shine product? Many Thanks! --Tai

I have to admit, i am impressed!

Great stuff! I'm confused about that pulley. I didn't see you cover it with foil. How did you protect it? Thanks for making this video. I'm going to get out there and clean up my 2004 Prius!

great job!

Nice please can give more info about 3th generation 2013 2014 Toyota Prius .like how to drive best eco saving. And also what i must know about the 3th gen.Becouse i buy 2013 with 38 mileage on the clock meter thank you please

@1:23 you said avoid water on this part. But you didnt show how to cover it. Do i cover it with foil? Tnx

The "gurgling" you heard wasn't the "hybrid engine talking", it was the brake actuator pump refilling the reservoir. It's something that notoriously goes wrong with the Prius more than anything else and it's expensive to fix. If you open up the good and start getting that noise cycling don't buy it.

I have two concerns: Worries me to wrap aluminum foil around electric connectors, just does not feel right to use a metallic foil. WD40 is flammable, probably not a good idea to spray it in an engine compartment.

Nice. My Prius 2012 Prius 3 has rat issue while it was parked for 3 years without use. I have some inner detail but after 12 hours or so the smell comes back. Where should I do detailing to avoid it?

Amazing job 👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽

Very well explained....

Can you do a tutorial for a 2012 Prius C aswell?

Wow, very impressive!

great video- thanks!! Question: on the Gen II Prius, you mention crucial to avoid pulley bearings. How did you deal with this? I didn't see you cover it with tin foil...... Thanks- good down to earth video.

Is it necessary to disconnect the 12 v battery?

You just saved me $40, thank you! Great video!

Thank you

Very good

I actually thought I was the only person that used aluminum foil, its the safest thing to use when cleaning engines

What good is a video that displays rough idle when cold and does not give a remedy, but switches to how to make your engine clean???

Can i clean my hybrid engine using only rubbing alcohol?

As long as you’re not blasting the bearing area with high pressure, there’s no need to cover it. Actually you should let your APC do most of the work and don’t use a brush this stiff. Agitate the really cruddy areas with something like a parts cleaning brush after letting the APC dwell then RINSE, don’t blast! You really don’t need to cover anything if done properly. It’s an engine bay designed to live with crud and a certain amount of water exposure.

Excellent job

nice video , thanks .

Look you said the poly should not be contact with water but you didn't cover it and you washed so y need to change the belt it makes me confused if possible please answer.

Very informative

SO CLEAR, THANK YOU.

Good job

that is a great work ,

What was the belt for in the Gen 2 Prius???

great job and good information

What is the all purpose cleaner you are using?

Enjoyed your videos.

He earned his ponytail!

What is the point to have clean engine?! It would be foolish to buy a car because the engine shine!

When I got my 2008 prius this year it was a one owner car with 140,000 miles. The engine bay looked as new as in this video. My first guess was it was garaged, do you think its that or would it be required to be cleaned over a period of 10 years to still look new?

Thanks for this video, but does the water affect the generator prius 2007.

How about those headights ? Any hints on cleaning ? My 2012 prius is as faded as that one.

What is the spray you are firing all over the engine compartment n hood before applying water at 14:08?

how do you know where you can spray the wd40?

Do a complete caomparison of both cars

Did you also use foil to cover the pulley with the barren

how do the 4th gen plug-in models differ? should they be cleaned differently? I have a 2019 Prius prime. thanks and love your channel!

Hi car angel can you please upload a video for honda HRV or honda vezel hybrid engine washing service

Good trick with the kitchen foil but spraying that shiny stuff afterwards especially around the windscreen wasn't great idea.

How about using a blower for removing dust

Can u remove the cover & spray where coils are?

Could you shine my camry hybrid for mefor me?

Great video but I wouldn't recommend trim shine or anything plastic with sun exposure. It would ruin the plastic.

How did you not wet the belt system?

Is it a good idea to disconnect battery. ?

Incredible!

How would you clean the 2009 Ford Escape Hybrid engine bay?

How much different is Trim Shine from a typical brand of wet tire shine?

For 3rd generations, only 3 areas to be foiled?

why do you have to remove the foil?

Gen 3 has an expensive to replace electric engine coolant pump compared to the Gen 2 mechanical water pump which lasts 200k. Also Gen 3 has an EGR valve that clogs after 100k and is difficult to service. So buy a Gen 2 if you want a cheap to keep Prius and go 400k.

Now, I am going to use tin foil instead of a condom.
