How an Active Engine Mount Works

[@IAMPOPP]

I never even knew there was such a thing as an "Active Engine Mount". I learn so much from your videos! My new favorite channel.

[@FrankySilverFace]

Was that your brothers engine too? Hahah

[@speedkar99]

Nope. I bought the car with my own 💰

[@gabedahlinghaus3594]

Hahahahaha😍🥰

[@ackinito]

You must be your brother's favorite. Great video as always.

[@speedkar99]

No he favours the little bro more than me

[@jumpinjohn54]

I've been wondering for a couple weeks now how this worked. I changed all my mounts in my 02ES300, but got stuck on this one. It was super tight coming out, then noticed the new one was bigger. So I stuck the old one back in, and was not able to get the switch mounted back on. Another great video. I've always had to know how things work. Been tearing stuff up since I was very young.

[@cck0728]

[@speedkar99]

Awesome thanks

[@MrCopRobo]

very interesting content! I was confused yesterday under my RX300 mk2 what is this vacuum line coming to mount

[@LugiaMCG]

what? lesser vibrations when active mounts are turned OFF?

[@carnage50x]

3 out if the 4 motor mounts are very active on my car.

[@ScubaCat3]

Very cool. I don't have the active ones on my camry, just 3 hydraulic (plus the dog bone). I do have an annoying intermittent vibration lately... I'm leaning towards replacing the side mounts since they are 18 years old now but I wish there were a good way to really diagnose them. They SEEM fine

[@speedkar99]

If oil has leaked out or you notice the engine rock alot back and forth when Changing from R to D then it's time to replace them.

[@ScubaCat3]

@@speedkar99 Nah, I took it off completely and it *seems* fine. But on another vehicle (ford minivan), I had the same thing where I couldn't detect a problem but it had failed internally - maybe a valve or diaphram broke - and was not absorbing vibrations. Replacing it fixed the problem immediately. With the toyota, they're just so expensive, I hate to throw a part at it and not solve the problem.

[@ScubaCat3]

@@speedkar99 Also, I replaced the front one and dog bone. I'm thinking the transmission mount is the problem

[@randomeyes]

brothers old sock lol.... Lol r u sure that wasnt ur own shirts and socks 😂 i liked that.. anyway good job on video i think my car needs new engine mounts.

[@evianway]

Good vid however I'd like to see breaks on, gear in, slight acceleration to see engine movement and what amount of movement is acceptable before we assess a bad engine mount or not thanks!

[@condor5635]

Another great video SK! Thanks I changed mine out few months back. Just not sure whether this mount is really worth it over a conventional rubber pad type one especially considering the expense!

[@speedkar99]

You'd likely feel the difference if you went with the non-active mount.

[@Redkit34]

Bro when you activated the engine mount you sent air into the mount and compressed the hydraulic chambers so you increaed the spring rate of mount. When there is no air in the system these two chambers touch each other and establish a softer mount. However stiffer spring is soft for higher loads and higher frequencies. When you rev the engine up to higher speeds you will need a stiffer sping mount to have a softer ride. You shouldnt activate it at lower revs or adjust proportionally. When you activated it you sent air at full rate. This gadget shouldnt be on off valve but a proportional valve. This is my assumption from my vibration knowledge and hydraulic control. I didnt know this type of mounts until I saw your video thanks again :D

[@Questchaun]

Seems overly complicated to secure a v6

[@rafaelrodriguez442]

I thought it would be the opposite. When the active engine mount is "off" , should the engine vibrate? I'm trying to figure out why I'm getting a slight vibration in the cabin when the car is at a stop and in gear. It's like a slight drone. Most people won't even notice it but I know this engine show be very smooth at when in gear. Could it be my motor mounts? 130k on car. Changed plugs Pcv Cleaned mas air flow Injector cleaners

[@speedkar99]

Yes it could be the mounts. If you have active mounts then use the scan tool software to enable and disable. If there's any noticable change then its working. Otherwise you have a vacuum or electrical problem

[@tlacki13]

Awesome explanation- TY! I had no idea that was in my car.. I went to replace the 3 lower mounts and found the front one that I got wasn't an active type. There's not a lot of room in there- do you have a video on how to pull this one out and replace it? Or at least, can you say if it comes out from the bottom or top of the engine compartment?

[@kbbkbbkbbkbbkbb]

very good video - but what I don't understand is when will you feel excessive vibration if one of these goes bad - is there primary use to reduce vibration when going at idle as the video seems to say at one point? Of would you feel vibration thru all RPM ranges, or ???

[@angelobovara317]

All that engineering and expense could have been avoided had the balanced the reciprocating assm.

[@Argedis]

Aren't V6 engines inherently smoother than i4 engines? At least at load. But what about idle? Are V configuration smoother than i configured engines?

[@speedkar99]

Yes V6 is smoother than i4. But i6 and V8 is smoother than them both. It has to do with the derivative of acceleration (secondary inertia forces), and how they are balanced in the engine configuration.

[@catsspat]

I6, H6, V12, ....

[@littymathew9493]

Hay nice stuff. Need your assistance. M driving a camry vu 2005 American spec in Dubai. However my concern is there is a slight delay few seconds when ever I raise the accelerator. Is this normal for v6?

[@littymathew9493]

I hav gone everywhere replaced spark plugs cleaned throttle replaced axles catalyst repaired gear box but I still feel the delay.

Great video! I had no idea active mounts existed. I have an unrelated question: at 6:35 I can hear your engine making almost a clicking sound, I guess, at idle. I have the same engine in my '00 Camry and it makes the same noise at idle, although a bit quieter. Do you know if this is normal or something to worry about?

My Toyota 1mz-fe engine mount was replaced with an aftermarket one a few years ago. The transmission repair guy said he needed to replace it. I noticed more engine vibration right away. It's not too bad though. However I I told the mechanic he should've told me before he replaced it so I could decide OEM or aftermarket.

Won't an issue with the hose (like a crack) or the motor mount cracking cause a vacuum leak issue with the engine? Kind of like causing a lean condition at idle?

Thanks for another great video. Our 2005 Toyota Avalon shudders/vibrates when accelerating from a stop so I'm suspecting it could be the engine mount or maybe the cv shaft. It s=doesn't vibrate at highway speeds or when braking.

When near a stop it's probably not the CV shaft. Check to make sure it's not the engine itself bogging down from a dirty throttle body or something

I must have totally misunderstood that demonstration. With the active engine damping mount turned OFF it was nice and smooth, and with it turned ON you could feel the vibrations? Seems a very expensive and complicated way to inject vibration into the chassis. I'd be looking for a way to permanently switch the damn thing off :)

[@speedkar99]

This doesn't inject vibration. It isolates it. When you turn it off, the solenoid turns off.
