People hate priuses but honestly if you have fun cars to drive having a reliable car that gets great mpg is never a bad thing. You won't have to worry about things breaking left and right like the merc

[@Gus11445]

So true.. got my fun Volvo S80 project car for the occassional weekend dates and special occassions but 95% of the time my wife and I use our Prius for errands and just going to work, a-b type stuff. It's unreal how much we have saved having a Prius, no regrets! The Prius is getting so much more poplular as time goes on... I've had friends and coworkers come to me saying they are looking/need a Prius for affordable transportation blah blah blah and I just smile and agree.

[@NINJA2da]

To take the entire EGR assembly out, I used an extra reach 12 mm racheting wrench for the three 12 mm Nuts in the back if the EGR cooler, took me a while to reach the 4th hidden 12 mm Nut underneath the EGR cooler. Used a Torx E8 socket and 1/4 inch drive finger wrench to remove the two stud bolts in the back of the EGR cooler to finally free out the EGR assembly

[@21boxhead]

Awesome video! Especially the attention to Detail. Thanks for sharing!

[@springer-qb4dv]

You were close when you were talking about EGR cooler. That is the main place where soot clogging occurs, as passages are pretty small. I took my EGR cooler off at 170K miles and it was completely clogged up with soot. I could not even see any day light through it when held up against the sky. That meant of course that EGR was completely off line with no exhaust gas recirculation occuring at all.

[@45AMT]

Awesome video of some good preventative maintenance. Some models of Toyotas are known for sludge issues. Might not be a bad idea to pop the valve cover and inspect under it. On my Tacoma i did and found a ton of sludge. I guess the prior owner didn't change oil enough. My oil pan had a ton, clogging the oil pickup screen causing low oil pressure. which in turn was making the valves tap.

[@Korium84]

Love this video. Very informative even though i don't plan on owning a prius. Personal opinion? Fix that valve on the merc so you can get the proper amount out of it. It's worth the time. Love where you're taking this channel, just stay true to it! Take care!

[@degeneratewinners]

Great video in maintenance on that Prius.

[@richardking6066]

I bought a used EGR valve and cooler on ebay - cleaned it up like new with oven-cleaner, all ready for when I need to clean the one in the car!

[@rondhole]

Thanks for the video. If it is 2010-2012, yes oil consumption from soft cylinder rings and head gasket leak at around 150k miles. After 2013, Toyota revised the head gasket and cylinder ring and no more oil consumption nor head gasket leak. The intake and below throttle body in 2013-newer is still wet from mixture oil+gasoline mix from blow-by but no problem at 100k miles yet.

Tips to PREVENT HEAD GASKET FAILURE: 231K - 2013 Prius. Just had head gasket replaced for $1,500. Could of prevented it if I cleaned/replaced EGR cooler my second run around 80K or 90K miles? Maybe it happened to me a bit sooner because I cleaned my EGR cooler out about 90% +\- at 130k miles, + 1000 miles/week, 50K/yr. and maybe because of potentially more cold/heat cycles on the head gasket. Lots of people highly recommend 3rd gen prius owners clean or replace EGR cooler AT or BEFORE you hit every 100K miles. EGR cooler $178 new on ebay, $300 at toyota, part #25601-37010. Clean EGR pipe and valve with the intake manifold/throttle body. Replace PCV valve, optional oil catch can. X At 230K miles my EGR cooler was completely blocked up with soot (previous cleaning at 130K). My symptoms were brief misfire on #2 couple times every 100 miles and slow engine coolant leak into the engine. #2 spark plug and #2 set of 4 valves were pretty dirty. Head gasket and cylinder head was replaced with refurbished one. (6,000/3month warranty). Car runs great so far. 4th gen prius has improved this problem.

Great video. I'm watching it before replacing for first time the spark plugs in my 2015 Prius at 155 k miles. By the way, the only 3rd Gen Prius that burns oil, is the 2010. This problem was corrected later models.

CLEAN YOUR EGR COOLER DON'T LISTEN TO THIS FOOL AND DON'T WASTE YOUR MONEY ON GETTING A NEW EGR COOLER IT'S EXPENSIVE YOU JUST NEED TO CLEAN IT WITH PRESSURE WASHER AND SOME COPPER WIRE

[@FishingWithMichaelTruong]

Not quite true. It happens for many Prius models that have a PCV valve design and also an oil control ring issue in the pistons that affected several different Toyota models in the late 2000's to mid 2015's (known issue from the factory). Toyota later went on to rectify the issue. Even still, the Prius has proven to be a very reliable car if properly maintained.

because of the hi voltage battery, you should disconnect the hybrid battery pack and reconnect it upon finish. to prevent electrification accident.

[@XTheJenovaProjectX]

I’m in the middle of doing all of this EGR Prius maintenance bull crap. I just bought the car and should have done more research. After the first week of buying it I noticed weird shaking/vibration and thought it was suspension/tire related. I paid a shop to look into it and even they said it’s probably tire balancing or CV axles. That was a waste of money. After tons of internet research I find out it’s this EGR stuff. Now I’m tearing it all apart trying to fix it. I just hope I remember how it all goes back.... 😭

Very helpful video, I have 2010 Prius 3rd generation 170 miles on clock . Working good since I bought, but now from last few days I feel a little hitch while driving before engine kicks. No noise or sign on dash board. Plugs changed 100k ago. After engine kicks no problem at all no matter how fast I drive. But as soon as I go up at speed 30-40 and time to push engine I feel small hitch like engine starts 1 second later than it should start actually . Any suggestions bro. Thanks

my 2014 prius has never burned any oil sitting at 110k miles today. 2010 model was known for burning oil, never heard of others having oil burning issue.

the oil issue was for my knowledge only on 2009-2010 models and they fixed it after ward. in general Toyota and Priuses alike can do half a million miles easily with out any issue apart then the necessary regular maintenance every 10K miles. and that's it.

[@gibson7654]

You should try castrol gtx conventional oil not synthetic. It will keep your car from burning oil. I use it in my Yaris and it doesn’t burn oil.

All that, just to access the spark plugs. What a fantastic design! Looks like the car was built around the spark plugs. Thanks for posting the detailed spark plugs r&r.

I had to do this on my 242k 2010 Prius a few months ago. Install an oil catch can and a new PCV while you're in there to prevent the intake from filling up with oil.

@@XTheJenovaProjectX Sadly the 2010 / 2014 Priuses, if it where not because of the engine piston ring design flaw, they would be among the most reliable vehicles, but because of these defects, they are not so good, that will turn into a pain in the ass in the future.

Nice video. I am about to clean EGR for my Prius V with 190,000 miles for the first time. Is it necessary to disconnect Hybrid Battery System ( Orange Plug to High Voltage battery. I don't want to disconnect and end up with some codes. I'll disconnect 12v battery since it's simple. I am thinking of soaking it in a small bucket of gas overnight and pressure wash it next day . Is that good idea. Also. once I clean manifold , can I reuse the same gasket or do I have to put a new gasket ( if it is not expensive). I subscribed Thank you

[@digitaltactics9234]

2010 ten 3 gen only was know for a piston ring problem was fixed 2011-2015. In 2010 they had a different piston ring manufacture. 2011 & up are fine just letting you all know if your looking at buying a Prius used.

[@JUST_ONE_ID10T]

You can tell the coolant has been maintained as it's way to clean to have 140k miles on it. They did it and didn't document it. Take it and have the fluids checked for health of the fluid.

[@niveKOnBass]

turning the heat on also starts the engine and keeps it on as well.

[@XTheJenovaProjectX]

Why do you need to put it into maintenance mode? I think I missed that part.

[@AY-dw4om]

you can start the engine just by pressing the gas pedal. it will awake it.

[@metrork1]

I would not worry so much about changing out my antifreeze fluid, I would be more worried about my head gasket blowing which is common on the 2010, 2011, 2013 as you reach 150,000 molies. My 2010 blew a head gasket at 157,000 miles.

And I thought a VW T5 van's engine bay is cramped. When you have to disassemble half of it just to reach the plugs, its a new level here.

[@melvinradcliff3624]

Wowowo. Tim

[@donhiebert3750]

If there's any clogging in the EGR pipe or valve, you can bet the EGR cooler (the box-like extension behind the valve going to the exhaust manifold) is completely clogged. That's where there either is a problem or will be a problem. Those are more difficult to get out as there are coolant lines, etc but it's still a good idea to clean that out thoroughly. After removing the valve, put a tube on there and blow air toward the exhaust/catalytic converter. If air won't pass through easily, that's where the problem is. Figure on sending at least 3 cans of carb cleaner through the cooler (after removing it) or just get a new one.

[@Mr19853]

Man that's a lot of work for just replacing the spark plugs! No wonder the prius tune-up is so expensive.

Hi UberMan

[@dieselbenzrevive6820]

I noticed my wife's Prius is not getting the same gas mileage that it used to. What things do you reccomend?

[@flagmichael]

If the thermostat has not been replaced recently replace it on general principles. Thermostats don't last forever and Toyota hybrid system are *very* sensitive to engine coolant temperature. The first gen fuel economy would drop 30-40% in winter because of overcooling. If the spark plugs are near the 100K mile mark, replace them now. If top tier gasoline has not been used most of the time (I never put anything but top tier in my Prius... they carbon up easily) add a bottle of Techron to the tank. The problems with drops in fuel economy are almost always one of these three things. [Nothing but Prius since 2002]

I think it comes down to the BMW being something most of us will never own. A v12 BMW, is just cool. The Toyota is plain and boring. And is an everyday car just about anyone can own. While it makes you money, it just is not fun to watch you work on. But you do have to keep it in working order, so it is what it is. At least you keep the vids coming, and allot of other YT channels don't.

You have REALLY got to lean how to drive a prius. Prius, IF driven PROPERLY can get you damn near 60MPG. Driving like you drove it in this video, I'm sure you'll get something in the 30-40 MPG range! I often get an average of 54MPG on mine (3rd gen)!

[@KaneLono]

Yeah maybe, but you also have to drive a Prius like a regular car now and then. If you always baby it for optimum gas mileage you will never achieve enough oil pressure to blow it out. That's when everything starts getting clogged up. Like the oil rings. You may get the best mileage driving eco all the time but your also chancing the oil burning problem.
