This was awesome Eric! Nice!
Love you Chris!❤️
impeccable timing too!
Thanks Chris!
I'm humble mechanic, this is my other channel. What's up guys?
Hooray for brotherly car guy support!
You got all these fancy cars with their quantum actuated engine mounts and then me and my hockey pucks.
I relate to this 😂
Haha!
And more affordable as well.
I'd rather have hockey pucks....
Hockey pucks ftw
Having a big bowl of ice creme watching ETCG1 explaining active engine mounts. Life is good.
Never knew if active motor mounts until today Great video!
I've seen them before but I called them the wrong thing.
I remember those hydraulic mounts with the vacuum hose attached. I recently replaced all 5 motor/transmission mounts for my brother on his 2006 Pilot. Yes I bought all 5 mounts from Honda.
Got a 2005 Pilot, how much did all 5 factory mounts run ya? How many miles on it before replacement and what symptoms did you experience?
XxHyJyNxX they were pretty expensive, not gonna lie. I probably spent about $300 at least. As far as symptoms, I noticed a slightly higher pitched idle on cold start and the front hydraulic mount was completely flat and every time I went over a bump it was really rough. Car now rides much better and I can honestly say that it was worth every penny given that the car at that time had well over 230k. I do recommend that you get Honda mounts if you have to do this job.
Michael Sackstein I haven’t even hit 150k yet on mine, gotta love “little old lady” specials! Honda service-records an inch thick. Purchased it 2 months ago for under 3k. She rides pretty nice, but I have noticed a distinct “rocking” noise and motion going at angle over speed-bumps, as if the engine is shifting left-right at a different pace and more freely than the body. The engine deflects only but an inch or so when revved in-gear, brakes locked, no noises or excessive lift... but upon harder up-hill throttling you can almost feel the engine hop back, like a bad torque mount on a 4-cylinder for example. Is this the troublesome rear mount?
XxHyJyNxX it could very well be that mount is on its way out. I would definitely replace them. The problematic ones are usually the passenger side motor mount, and the front hydraulic mount
XxHyJyNxX it could be that your suspension needs work as well. Sounds to me like struts and sway bar links. I recently refurbished the entire suspension on my brothers 06 as well.

I never knew there was such a thing called an “active engine mount” that’s controlled by vacuum or the computer. But I just did engine mounts along with a few other things in my mini and holy crap what a night and day difference that was. I’d hear the engine clunk whenever I went over speed bumps. When I replaced the lower engine brace I noticed the rubber bushing was gone because the leaking oil had eaten away at them. And yes I did address the oil leaked as well
Very informative! Thank you AI and Eric for giving us a concise and detailed look at different types of engine mounts.
Great timing Eric! My Crown Vic has a bad mount! Put the car in reverse, with the hood open.... Apply some throttle.... and up it comes! (Non Active, just like your truck)
Thanks for reporting on the engineering boy's latest edition on how to add something consumers never knew they needed while adding complexity and cost. Not to mention additional headaches for mechanics sorting out vibration issues.
This is pretty cool, something I wasn't even aware of. It would be neat to use this in a custom application. On my stand alone it would be super easy to trigger these when the TPS is at a certain percentage through the nitrous control output.
Thank you so much for this information! My wife just told me she was experiencing clunk when accelerating and when switching gears this morning in our 2014 Honda Odyssey. It's been a great vehicle. This looks like it will be quite involved for me to try and fix. We'll get it done.
Great explanation Eric! I had no idea that were Liquid and So Many other Variables of Motor mounts!
Eric, you're having way too much fun! I appreciate this, it solved the problem with my lesabre shaking on acceleration in a right turn. Dude, you rock!
Ok, really like this kinda of vids, both the explanation and the examples are super informative and clear. Thanks!
Wow!!! What a great freaking video Eric!!!! Thank you so much. Learned a lot, and I’ve been an mechanic for 10+ years lol
Really superb, Eric, and Damn! what a set of pipes! This is certainly an understatement, but you've got one of the best inf not THE best voice-over/voice-talent guys on TH-cam or the internet. Really top notch.
I've never hear of active motor (engine) mounts, but I recently replaced the three on my old 2007 Saturn Vue, and WOW. You can actually carry on a conversation in what was rated as a really noisy car. Lovin' it... Great advice and well delivered! Thanks... Don
Why don't I know anything? I've never heard of active engine mounts! I thought that they were just rubber units sandwiched between metal mounting blocks. I suppose the next stage is when we need a $1500 scan tool to reprogram them whenever they get replaced - that'll be something to look forward to. Anyway, enough of that rant. Great quality video - still the best on TH-cam. Long live ETCG!
Thanks! Perhaps we'll be switched to electric by then. We won't have to worry about idle vibrations then. As always, thanks for the comment.
Thank you Mr. Eric. I appreciate your channel immensely.
That's a really good use of a sponsor!! Really educative too!! Thank you Eric
Yea, I was very happy to make this video. Thanks for the comment.
Cool 😎 I never seen a cut open view of a active motor mount👍
Now this is how sponsored content should all be done. The sponsor gets a nice subtle bit of recognition while enabling the host (Eric) to better illustrate the function of the component.
Very nice cut open demonstration of all the engine mounts Eric 👍👌
Nice job on the video. Very informative and professional.
Thanks for the explanation Eric, very useful
thanks man i just replaced my wifes 2006 honda odyssey rear mount all the juice was coming out of it and was vibrating real bad. Wanted to learn more how it works. Much easier to do then my 2002 odyssey with the other style mount. Appreciate you
Another expensive and over engineering idea doomed to fail that only gives a small return on investment - except for the manufacturer and the mechainic getting $100 an hour plus parts to replace them. Reminds me of when Cadillac put shock absorbers on the fenders of the old Sevilles to stop minor fender shake that was present because it wasnt a real Cadillac but rather a Chevy Nova subframe that shook like a leaf. Yes im that old. Still a very informative video Eric, thanks again.
These have been around since early '90's at least.
@@FixingWithFriends only you will never get an active mount that lasts as long as one that is not.
Which is terrible for a section of the frame.
All for ONLY the sake of comfort.
I'm gonna tear mine out and put polyurethane mounts because that's enough to deaden the light vibration that can wear out the mount bolts, idc about vibration in the cabin I'm not a woman
Eric I just changed the front mount on my wife’s 99 Accord with active engine mounts but it has the vacuum line on the bottom but the vacuum is ported from a valve up on the drivers side of the engine compartment. Thanks again for the video and stay dirty and well 👍👍👍 I had a slight vibration in steering wheel at idle and hook up a vacuum pump to vacuum port on mount and it would not hold vacuum. Also changed all the vacuum just for reasons of age they were good but what the heck 😊😊😊
Right! You don't want vacuum leaks!
Thanks for video. My favorite type of engine mount is on a racecar. Engine bolted to metal bracket, metal bracket then bolted to frame. Done!
I learned quite a bit. That was awesome!
Thanks, Eric. I appreciate how you reviewed the history of engine mounts going from semi-solid (rubber/steel) to vacuum, and then on to liquid and electronic combinations.
I was wondering how the active engine mounts affect the drive train, in particular the drive shaft? The drive shaft is often neglected as a crucial component of the drive train system. So often, the height of vehicles are changed by different-sized tires, or suspension system and the drive shaft is not checked for parallelism to the driving surface.
This is an important aspect of drive train engineering I would like you to cover in-depth in a future video.
Thanks for another brain stimulating video. Now I know that if my car is rockin' my active engine mounts could be knockin'. Jeff
They don't usually use these on rwd cars, and a fwd can axle can take a lot of flex
I actually touched on ride height affecting driveline angles during the #ETCGDadsTruck series. However, it didn't specifically reference engine mounts. Perhaps at some point it would be worth revisiting. Thank you for the suggestion.
@@xxRamD3yruxx Anytime an ICE engine is placed in the front of a car a drive axle must be employed to transfer locomotion to 4WD, AWD, and RWD vehicles.
@@jeffkelley3419 right, but a cv axle is not as likely to have a driveline vibration as a driveshaft with ujoints. I would say the inherent differences in the way rwd vs fwd cars are built and the physics involved negate the necessity for an active engine mount
1995 honda odyssey rear mount was a vacuum engine mount. There is a lever near it don't know what it's for. Gave up trying to fix. Has 300,000 miles on it. Thanks very informative
This was awesome !! Im glad your taking the time to do this !! keep up the creativity and thanks again !!
That was a GREAT video Eric, I NEVER KNEW!!
Thank you!
Great information in a short video.
Eric, do you really buy these just for the sole purpose of cutting them up and informing us? Thank you so much for these videos!
WOW, awesome information. Very informative, thank you!
I didn't even know about active mounts until this, interesting to see. I know none of my vehicles have ever had them. Speaking of engine mounts, I'll be unbolting them in my 91 Lincoln Town Car soon to lift the engine and try to change the oil pan. Had to do this in my Ford Ranger once as well, what a pain in the backside. If you need any content Eric, I have a few vehicles that could sure benefit from your lift and or engine hoist, I'll do the work, lol. Anyway, thanks for the cool videos Eric!
Nice educative video, more like these is a good thing. Now I know there is such a thing like "active engine mounts". Makes lots of sense.
Very cool Eric and I bought a trans mount from them a month ago and doing my engine mounts for the hell of it now
From Anchor?
Are there motor mounts decent?
Great video! Tnx for explaining Eric!
All the blown engine mounts ive personally seen have been on stick shifts. Seems like they take more abuse than autos. Either the driver feathers the clutch too slowly and they go through clutches or they pop it too quick and go through engine mounts. I talked to a guy last month that had bad mounts on his automatic truck and thought it was Odd. I tend to get a lil aggressive with my driving so I've had a few manuals that I had to replace mounts on. Mounts seem like the last component that absorbs rotational force from the power put down to the tires. As it propels the vehicle along. And they are susceptible to hard Jerky acceleration.
Good stuff! Thanks, Eric!
Great video,Eric! Using marbles for showing the little movement was a great idea!
Excellent summary!
Thanks for the informative and fun video Eric
Great Quality Video Sir, very Informative and Educational.
Learning something New everyday. - Every-DAY.
.Thank You!!!
Great video. I would think manufacturers need to go back to better engine design versus overcomplicating the mounts used. I once owned a 1988 Toyota Cressida with a 2.8 liter I6 motor and it just had standard engine mounts. The motor was so smooth and quiet you couldn't feel it idling when inside. If that car can be that smooth and quiet with old and basic mounts why would a manufacturer need to go with such fancy mounts versus good engine design and tuning?
Great job! Love the cutaway views!
Great video Eric
those cut-outs are awesome!
More fancy stuff to go bad.
My introduction was the nissan/infiniti active mounts would burn out circuits in the PCM and cars could not get through emissions because of the stupid check engine light was illuminated.
Interesting. Glad you got it sorted.
AWesome Knowledge Sir..I never new that.So educational ..Keep them vids coming
Thanks Eric. I'm only familiar with old school rubber mounts. I never knew they had "active" mounts. Honestly I think it's another excuse for the car to set a CEL and send people to the dealer but I appreciate being educated.
Thank you soooo much for making this video!
Thank you my 2004 Acura tsx will be getting a set of anchor mount
Learn something new every day!
Actually pretty cool. I never knew that
Awesome video Eric, thanks!
Very interesting information. Thank you Sir!
That is a great description.
Damn i have a honda element and your videos are helpfu0l thanks for sharing
Glad you find the videos useful. Thanks for the comment.
Thank you Eric. Awesome video. Help me out a lot.
Reverse to drive? Some of us have a manual transmission 😂
Great video. Just had a vacuum line to my mount go bad and caused a vacuum leak and fuel trim problem.
Always good to know! Thanks very much.
Great video Eric, thanks.
Good work on the video Eric
cool, nice little bit of knowledge spreading - thats a good thing! cheers.
Thank you Eric I enjoy watching your educational video I am from South Africa 🇿🇦
Hello South Africa!
@@ericthecarguy hello USA 🇺🇸 😂
Just wanted to let you know this is still a great educational video. Thank you:-)
This was video gold
There is nothing better then original parts
Great informative video.! Thanks
While it seems a bit excessive to me, this was really cool to see inside these things though.
Thankyou brother great knowledge
Thank you mr.eric
Very cool! Thank you.
My engine mounts are all made from the finest bespoke, UV aged, ripped rubber...
Why are your mounts in the sun light
You. Are. Awesome.
Great video learned something new today.
감사합니다
Great Sponsorship!!!!
Informative, thanks.
Thanks Eric!
Very interesting
A very well done, informative video.
Unfortunately in the Nissan world when motor mount electrics shorted, it would also take out the ECM. Quite a surprise for the customer after warranty time expired.
This is interesting to watch.
Way to go! I always learn a lot from your videos. Thanks.
What knuckle head gave you a thumbs down? Must be electric car guys. 🤦♂️
I would have like to know how the vacuum actuated the upper mount chambers. The physics and all. Thanks for the vid, I will probably buy anchor mounts from now on
Good stuff! Thanks for explaining Eric! :)
Putting in new mounts can make a world of difference in the smoothness of your car. I replaced mine on my 01 e320 and now I can hardly tell it's running. They are oil filled.
cool vid! great work
awesome!!! thank you
Great video. From the state of pa.
What is your opinion on shin etsu grease
Very cool👍
I've noticed that when I run the A/C, the engine has a bad vibration/rattle from idle to moving. I think because the engine is being run a little harder with the A/C engaged makes the motor vibrate more. Therefore when the motor mount failed the mount tend to cause a vibration rattling sound.
Edit: Also, popping the hood, left foot on the brake and right foot lightly on the throttle. If you see the engine jumping a little excessively, it's a sign the motor mounts are bad or going bad and you can tell which ones failed.
Check your ac compressor bearings and belt tension first.
@@scallywag1716 Oh, I know the A/C compressor is bad. I took it in to the shop and they just replaced one of the hoses and a month later the A/C stopped working again. It only works when I go 80mph, LOL. Seriously. Luckily, I'm in Texas. It's 2011 Hyundai Sonata, the car has all this new gen technology for its time. Its called Variable Valve A/C the clutch is eliminated. The A/C compressor has a tendency to have an electrical failure. Also it's got hella problems, I can probably fix most of them, but I tend to stay away from A/C compressors because I don't have the refrigerant to recharge the system.
@@scallywag1716 Also the car has 120k miles on it. All the motor mounts failed, failed right rear upper control arm, airbag sensor stop responding to the BCM, the steering wheel radio sound controls flips the volume up button to a volume down button sporadically (physically hitting seems to fix it, LOL), the window hold down switch that normally whines down the window automatically when fully pressed broke. I'm lazy in working on this car, plus it's got damaged by a Hyundai dealership in a car wash. It's paid for and honestly, I'd just rather buy a new car and truck, 2016+ Camaro 2SS and a 2016+ Silverado CrewCab 1500. I'm pretty much done with imports.
It's a whole new ball game with these on Honda's VCM engines (Ody, Pilot, etc.) I assume they get softer during cylinder pause to absorb the vibration? Too bad these Anchor mounts don't usually last a year in the Honda VCM vehicles. Would be great if one of these aftermarket companies made an active mount that lasted in that application, since Honda charges $6-700 but at least they'll last 100-150K or so.
Wonder if they offer it for older cars. Nice video eric!
I'm going to have to get busy swapping mounts on my 2007 Civic soon, (non-active engine mounts) just hard to switch into second gear lately.
