Toyota's New Engine Technical review Part 1 : Cooling,Lubrication,Direct Injection and EGR

A Toyota Master Diagnostic Technician goes over Toyota's new engine technical review in simple and easy to understand terms.
The new A25A-FKS and A25A-FXS engine from Toyota is widely popular engine in 2020 across multiple Toyota models both gasoline only and toyota hybrid models.
This engine is a marvel of engineering with so many advancements in technology. It is possibly one of the most advanced and efficient Toyota engine ever made.
In this series I will go over it's key features that makes it different than other engines.
In this part of the series I will go over the following systems of the engine :
1- Cooling system : With an electric water pump this engine gets a rapid warm up thanks to it's priority cooling system using valves to direct coolant where needed.
2-Lubrication system : Variable pressure oil pump makes load on the engine low while optimizing pressure for continuous engine lubrication at all engine speeds. The use of 0W16 oil is a must in this engine.
3-Direct injection system D4S is a genius system using both Direct and Port injectors therefore resolving the issues with direct injection carbon build up common on direct injection only engines.
4-Exhaust Gas recirculation : The system is back on gasoline only models.

The port injection allows fuel flow over the intake valves to remove carbon, it’s also makes better low rpm torque using port vs direct. The other thing it allows is for the engine to go through a direct injection self cleaning cycle during hot idle. The direct injectors actually have the ability to blow the carbon off of their tips and sides while the engine runs on the port injectors. Genius system.

In regards to the EGR cooler. My coworker has a '15 Prius C and the EGR is fed post-cat. She uses her vehicle to commute 45 mins on the highway each way to go to and from work. Car has 120k on it and is serviced at the dealer. She was experiencing rattling and loss of power under low load (think stop and go traffic), every once in a while when the car would start up (Prius death rattle), and when the ICE would turn on after switching between electric and mixed us (middle of the eco bar). She went to 2 dealerships and 1 independent shop and they all told her nothing was wrong with her car because there was no codes stored or pending and they couldn't reproduce the issue. I called a 4th shop that are Toyota specialists and they told me they wouldn't be able to diagnose it unless it threw a code or had one stored or reproduced the issue while a scan tool was hooked up to the OBDII port. I contacted my buddy who owns an independent shop and I told him what it probably was, but to also run some other diagnostics just to rule out a bad coil, etc. Well, her EGR cooler was clogged solid. Once it was replaced, it runs fine. The passages are too small on the EGR cooler as designed. This EGR will clog, it 's just a matter of time. The only improvement that I see is that there is now a separate plenum that feeds the exhaust gas into the head / intake manifold.

I am totally amazed at my 2.5 Dynamic Force engine in my 2020 Camry LE (8,350 total miles) I recently took a 445 mile trip that put my car through just about all the scenarios a car could face including, freeway, hills, mountains, long gradual inclines, long gradual declines, 78 miles of winding uphill, downhill, sharp turns, not so sharp turns, manually downshifting, manually upshifting, and driving around a small coastal California town of Fort Bragg for two days. After I came back home I filled up the tank to check for the first time my gas milage turned out to be...an amazing "35.8 miles per gallon." I had to redo the numbers on my calculator to double check...445 miles divided by 12.4 gallons of gas. I am totally amazed! And all these miles were not "easy interstate miles"...only about 125, or so. My car performed better than I anticipated and this engine...totally amazed me! The car is rated for 39 MPG (freeway) on the window sticker. It looks like it would do even better! Totally amazing!

Heated thermostat can be used during warming phase as described but it also allows much reduced HP load for coolant flow. With the coolant flow valves and variable speed electric water pump there is no need for thermostat to have any temp control function other than speeding initial engine warm up. Once engine reaches temp the water pump speed becomes the main control of heat energy rejection. Low load creates low heat and low pump speed is all that is needed. The pump can run and move all the coolant needed with only 250-300 mA, maybe less. The mechanical water pumps oversupplied greatly and thermostat would reduce opening to keep coolant temp higher. Pushing water through the reduced opening takes fuel for that extra work.

[@JuniorBetch]

Heated thermostat is used incase the driver decides to go full throttle with a cold engine, it opens the thermostat to even out the coolant temps otherwise you’ll have a cold and extremely hot area of the system

[@dominicd2694]

@@usercoimbar You made a great choice, it's absolutely an amazing car. From the styling, comfort and Lexus quality/reliability. I have never been a turbo lover and always avoided buying cars with them. Turbos create to much heat and pressure and with modern engines with all the plastic, you are just asking for trouble not to mention turbos don't last. Toyota/Lexus uses a bigger engine with a smaller turbo, so it should be more reliable compared to say German cars where they put large and sometimes two turbos in the worst location like on the top of the engine above the manifold. One thing people don't know who own vehicles with turbos, is that you can't just shut off your after driving, you need to idle it for a few minutes for the turbo and oil to cool off for a bit. I think the NX 350 uses a 2.4L with turbo. Congrats on your purchase.

I dont have direct f.i. but i tried 0w30 mobil one from walmart an dad was like next day what did you do? On crank up, you could hear a rough dry start noise mostly the timing chain or in honda accord k24 2.4 the variable phasing cam gear innereds not having oil

[@rstuff1605]

But even using 5w30 ive used conventional castrol and that got hot even though heavier than 0w30 mobil one But the 10w30 conventional castrol had valve tap idling just 5 seconds before turning off but it did hold up to 30 plus minutes of driving. Thats just dandy So i did what i had to do. I made a cocktail 1 qt 5w30 to 4 qt 10w30 and a drop of lucas stabilizer

[@craiglutska2850]

If you’re on the outside of my car you can actually hear the relay is clicking and the pump shutting off so that I know it’s the direct injection

[@rstuff1605]

Otherwise i use 5 qt 5w20 + 0.5 qt lucas stabilizer which is half qt over full mark Its all good. You just have to loosen fill cap anywhere say quarter to 1.5 turns Depending on HOW MUCH MORE PRESSURE YOU HAVE. You can have more of thin oil and get similar oil pressure as normal amt. Of say 10w30 Some 10w30 are thinner or thicker but within spec Racers would put more oil an a breather filter in place of the fill cap

[@rstuff1605]

@@craiglutska2850 have u ever tried putting the key to ON for anywhere from 2 seconds to 10. My friend doesit for 15 in his z28 thats too long lol I think it primes and builds up pressure in oil and fuel pump But the longer i do it, depending on the car, it uses more fuel lile its being heavy duty? Guess that's good to keep it cool in the summer lol

[@volvo09]

Agreed... thin oil is NOT as bad as it seems. In old cars, (even going waaaaay back to the 1920's) oil was primarily a lubricant and it's partial coolant properties were a side benefit that didn't matter, the older you go the less importance cooling was because metals were more tolerant and engines didn't make much power... As cars got newer they started to make more power and oil flow was increasingly needed a coolant, even commuter cars got oil coolers (once a high performance thing)- then oil had to travel to more places, while moving quick enough to do hydraulic things (variable valve timing, variable lift, turbocharger cooling and lubrication) and flowing oil is more important. It may flow like water, but it's supposed to, and it's supposed to be designed around that. If you are even doubting the oil in the least, just change it more often.... nothing bad will come from that... oil wear and buildup is way worse on these new engines... If there's any motto it's "keep it flowing" not more pressure.

[@jamrogjan1509]

what do you think about the metallic flakes i saw in my drain pan after using 0w-20 that are not there after using 5w-30 in a 2018 corolla with 75K? every oil change had a little very fine metallic debris until i switched. i think the lighter oil is purely for mpg's and is sacrificing engine longevity.

[@waterloo123100]

Thicker oil helps with fuel dilution. It’s a big problem with cars idling and running 0w 20. The only thing thin oil does good for your motor is fuel efficiency

Hi AMD, you are excellent at making the extremely complicated explanations simple. After having watched your channel over the past 3 years I purchased the same exact car(2023CamryHybridXSE)as you except in silver,without the black top.I traded in my 2017 Audi A8l 3.0 w/ 32k miles. I had previously owned over 20+ years only BMW’s.,from a 2006 750li ,to my last a 2015 X4. I truly loved the technology of the German cars, but found them to be finicky and problematic (not all of them). What I felt was that the technology was forced into the car because of trying to always one up the competition, either in the engineering and or entertainment/safety. Which brings me to this video and how you describe the Toyota 2.5 and the painstakingly thought out process they took to design this motor. I have always been a big Toyota fan from my very early 20’s . My first one I owned was a 1977 white Corolla,then 1979 Celica hatchback. The last Toyota I owned till now was a 1985 Toyota Celica ST that my brother bought brand new. He gave me the car with 150k miles, which I took to 210K , and sold with the original clutch and NEVER 1 issue. I went to the Toyota dealer this past Dec , and when I drove the 2023 Camry Hybrid I was blown away impressed(your descriptions were spot on). I really like the looks, and even acceleration was good , making me impressed enough to buy it. I would just like to thank you and your wife for making the channel and staying with it. I do actually have a question on the use of the paddle shifters. If I use them to downshift in trying to slow the car (charging/save on the brakes) am I putting a lot on strain, or doing damage to the transmission? An why do I see in certain blogs that they say the brakes last a lot longer on this particular hybrid? Thank you for sharing your talents . God Bless you and your family. 🙏Eddie S

[@mtjsrc1]

That was an excellent explanation!

[@symmetry08]

I heard that Toyota used their own small invention which is tumble method to efficiently mix fuel and air ration, upon entering the cylinders. It is a method of changing angle of entry and instead of traditional swirling around, mixture enters directly and swirl sideways.

[@obsoleteprofessor2034]

I have an old 80's EEC-IV Ford book that went into detail on how many microseconds it took for the computer to calculate injection times. It said the computer used up only 30% of its computational speed. Now that computers are faster, imagine how many additional factors can be taken into account.

This engine is very cool, but it's the reason we just bought a 2018 Rav4 instead of going newer. Really complicated and the last generation 2.5 has already proven itself for many years along with the 6 speed transmission.

[@zarirunvala]

I just bought a 2018 RAV4 Factory Certified Pre-Owned with 27,000 miles on it and I feel more secure in my decision, thanks to your post!

[@user-tb7rn1il3q]

The last generation 2.5 didn’t have enough power in the mountains and wasn’t particularly good on gas. In addition the previous Gen RAV4 didn’t do great in crash tests. The 2019 plus is better in every way. It’s bigger, basically a shrunken Highlander, and is much stronger (better protection and handling). The 2019 plus has a spin on oil filter which is DIY friendly. The 2018 engine is also very complicated.

Love your videos! We appreciate the technical knowledge you have!! A comment on 0w16. These engines are spec'd only 0w16 in North America, but in the Middle East and Austrailia they are spec'd for 0w16, 0w20, 5w20, 5w30 and 10w30. I don't personally feel there ever would be any negative effects other than fuel economy from using any of these oils in any engines as long as the temperature range is not exceeded. 10w30 below 0F. Toyota and Lexus have recommended even 15w40 in the GR engines above 20F in the Middle East and Australia. Toyota does maintain that 0w16 is recommended for all temp ranges as well as all by 10w30 is also recommended for all temp ranges. But 0w16 is preferred. A concern I have see on my 08 GS450h (2GR-FSE) is fuel dilution, and on the lower viscosity oils this can be very detrimental to engine life. Have you seen any oil analysis on the Dynamic Force engines or the GR and UR engines?

[@TheCarCareNut]

Hi! No fuel dilution issues on the dynamic force yet other than cars that are frequently driven short distances and go 10k oil changes against the recommendation in the manual

A certain German car manufacturer using electric waterpumps - YAY MONEY PIT!! Toyota using electric waterpump - it must be damn reliable :)

[@amazoidal]

It's not that reliable. Ask GASKETMASTERS, who replace all the blown head gaskets caused by Toyota electric water pumps. Toyota electric water pumps are poorly designed. The impeller is too small, and the impeller rides on a circular armature that has a plastic rim. The plastic rim cracks and jams the impeller. Then the pump is toast. Stay with a Gen 2 Prius with a conventional water pump that lasts 200k+ and costs $35.00 to replace. This old water pump will probably let you know when it fails and you won't be calling GASKETMASTERS or worse, junking your car with a fried engine.
