The brands you mention are fine, I’ve only heard bad things about Pro Parts Sweden which fcp recently started selling

 

Pro Parts is kind of hit or miss. Engine mounts, coolant hoses, and seals from them aren't great from what I've read, but I got a replacement mirror glass from them and it was great quality and super cheap for what I got.

 

Between fine and genuine volvo stamped, where are they on the scale?

 

I mean are there any OEM Engine Mounts which are the same as the genuine volvo ones sold by dealers?

 

I just put Hutchinson mounts on my daughter's 2006 2.5T and they had the Volvo logo ground off

 

Any particular vibrations or change in ride quality for the worse?

 

No. I assume it is the same as the original part

 

As far as I've read so far - the Corteco mounts are same as Volvo original, just lettering removed. But..on a youtube comment from a guy who worked for a distributor, the genuine volvo mounts have been pre-screened for defects by Volvo themselves and scrapped if they don't meet specific quality criteria of Volvo. On a different forum a member said his Corteco vacuum mounts held no vacuum and likely were a bad batch which he returned, a different user claimed his OEM mounts were leaking air/vacuum when he tested underwater. So this seems to be the main difference - quality.

 

FWIW, while I don't know what brand a previous owner of my C30 put on, but they had replaced the primary passenger side motor mount maybe within the last 20,000 miles or so. When I removed it for my recent work, it was clearly already shot. Rubber was sunk in and it was leaking. That's pretty bad. Prolly a PPS part. Haha. Anyway, I ended up replacing it with a new "Volvo" one.

THAT SAID, on my XC70, I replaced both primary motor mounts with some Cortecos about 1.5 years and 20-30K+ miles ago and they're holding up just fine. I think the main thing is either go Volvo or make sure it's a high quality OE version. Don't cheap out and go with PPS. They're garbage. Haha.

 

Regarding the primary mounts(I assume you mean lower front and rear hydraulic mounts) is there really a difference between front and rear? According to a few videos, one is slightly taller, but in another video a different guy said he saw no visual difference between both. I am asking because the lower rear is $30 more expensive than the front.

Addendum: It seems I was mistaken about FCP euro, just because they are named FCP Euro does not mean they are based in the EU.

Anyway, elsewhere it is said eeuroparts is the largest supplies of engine parts. On their website they list the Hutchinson lower mount as fitting both front and rear Volvo Engine Mount 30778952 – Hutchinson 586338 Hutchinson 586338 but on googling these guys it seems almost everyone had bad experience so I'm gonna assume their info is wrong.
But regardless even IPD USA says the lower mounts are identical to each other Engine Mount for Volvo - Hutchinson - 30778951 - 112761

 

FCP Euro is based in USA, Groton Connecticut to be exact. If any part has the Volvo name ground off from it, then it's the actual manufacturer of the Volvo blue label part. So if a Hutchins mount for example is identical to the factory original but has the name ground off and not just stamped flat on that side, then that's the same manufacturer as the original part sold by Volvo. The main hydro mounts may be Corteco while the passenger side mount is Hutchins. That all said, I've used a few PPS parts between my current S60 and my previous 1st gen S40 and have not had any issues with their stuff. Currently I run a PPS poly lower torque mount and have had 0 issues with it in the 5+ years I've had it on.

 

I replaced all of my engine mounts last year with Hutchinson branded stuff from FCPEuro.

I didn't notice any difference in NVM but my car also does not ride like OEM, but no idea if these pieces will last as long as the OE Volvo parts. FYI, after 150k miles, my cylindrical lower front and rear mounts were still perfect when removed, so you may be able to get away with not replacing those (the most difficult ones also)

 

Sadly I could only get the vacuum mounts from Hutchinson, I had to get the other 2 from Corteco and the lower torque rod is supposed to be genuine volvo, again, supposed to be. I am very hopeful I get an improved ride.

 

I must disappoint. While in Park and at a stop light, the idle vibrations are now higher with the upper Corteco and lower right Corteco mounts than they were with the broken mounts. Those are definitely not what Volvo dealers sell.
Funnily if I raise the RPMs slightly higher the vibrations quiet down and disappear.

 

That's odd. Your description of how the vibrations quiet down when you increase RPM is what happened when my motor mounts were broken. Are you possibly missing a mount? I think there's 4 overall. Maybe something else is going on?

Maybe POSSIBLE you ended up with defective new ones? They definitely shouldn't be acting like that. Bolt holes weren't stripped or anything, right? Make sure everything is torqued down properly too.

 

There are actually 5 mounts. I've replaced 3 of 5, with the other 2 being the two fat ones on the subframe, the lower rear and front which I have not yet replaced because they have not arrived yet. I'll be using Hutchinson for those.

The lower torque rod I used genuine volvo, while top and right mount being Corteco. I should correct myself though, the vibrations are a bit worse in Drive and sitting on brake, while in Park they are...normal I think or maybe slightly worse.

 

What you're experiencing sounds normal for polyurethane mounts, not standard rubber ones... My car needs to the passenger side mount replaced badly, and she vibrates with a vengeance at idle, lol. It's enough that it's caused 2 separate poly upper torque mount inserts to be gone through within 3 years before realizing the issue!

That all said, I wonder if your issue is either something not torqued down to proper spec, or could it be your subframe bushings? Those get warn and sloppy after time and also eventually need replacing... Not sure if those would cause what you're experiencing though.

 

That's the thing though, I am sure I didn't order polyurethane mounts, nor did I expect Corteco to be polyurethane. And if I slightly raise the RPMs the vibration goes away or at least is substantially reduced. I consider it to be annoying as it causes the door panels and plastics to resonate e.g I get a buzzing noise in addition to feeling the vibration in the passenger side, driver side and even the seats(free massage?)

I don't have a durometer to compare the rubbers though.

 

Just buy Lemförder and be happy. Its a major OEM player in EU and probably the highest rated OE distributor of aftermarket parts for the european market.

I wanted Hutchinson as that is what FCP Euro sell, and the reviews are more than splendid, but...are rare in my country. And someone said Corteco are one of the original suppliers to Volvo e.g genuine parts so I took a gamble, that maybe didn't pan out.

And I know about Lemförder in fact I could've gotten it at 20-30% discount, but I wanted Hutchinson or Corteco, if the Hutchinson mounts are not genuine volvo with the wording burn out, then I may consider trying to order genuine Volvo, but the cost is higher.

 

Actually am not sure who is the original OEM supplier of the P2 mount. I know corteco atleast has been an OEM supplier for alot of vehicle models out there but there seems to be some concerns about where corteco parts are manufactured today.

What I do know is, a lot of people, including myself, whenever possible and when cost difference is within a margin, go Lemförder and be happy. Almost everything I buy, if it's not OEM its Lemförder, TRW, MeyleHD or Sachs (and INA, Valeo and F.A.G for bearings as they are normally OEM)

Actually Corteco were more expensive than Lemforder. In any case as soon as I replace the two fat subframe mounts with Hutchinson I will post back if it solved my vibrations. If it didn't I will know it's the right passenger mount with code 30748811

 

Ok, so one final correction. With the old broken mounts, I had less idle vibration(in Park) than I do now with the new ones(I am yet to replace the two subframe mounts) and even more in gear with brake applied. I know I said it was fine before, but today I did another test drive and I can confirm I get more idle vibrations compared to before. Like before I'd be at a stop light in the passenger seat and car in Park and I'd feel fine. Now I feel like I am getting a massage and the door panels have more buzzing from them.

For anyone reading this in the future: Yeah it's a brand new mount, but avoid Corteco for the lower right engine mount(also called passenger mount) as it transfers more vibration in the cabin.

 

For vibrations into the cabin, I have found that the upper engine stabilizer contributes a lot to this. I had a poly one from IPD for several years and the dash and steering wheel rattling would drive me crazy, but not enough for me to change it. I finally changed it over to a OE style bushing from PPS (ProPartsSweden) from FCP and it is wonders better. Not perfect in terms of idle vibration, but much better. At the same time, I also understand that it has been ~100k miles since I replaced the OE Volvo rubber mount with the IPD PU one, so things in the dash are definitely more loose in general, and the engine itself is probably not as smooth with 150k on it compared to when it had 30k.

I, also, find that sitting at a light in N (Manual) that the vibrations are the worst. If I give it a slight hint of throttle to raise the RPM's from the 800rpm idle to 1000rpm, the interior vibrations quiet down significantly (think dash/cluster rattle, wiring harnesses behind the radio, glove box, etc). I've done my best to take things apart and add felt tape or rubber gaskets to tighten things up but there are still rattles in a lot of places, but I would consider this pretty normal for a 12 year old 150k+ mile car.

I would also think twice about replacing the lower two cylindrical style engine mounts. They're by far the worst to replace (the rear one above the steering rack is difficult) and mine at 150k miles were perfect, so maybe thoroughly inspect before going down the path of replacing. It will also be worth it to check out the condition of your subframe mounts as if they've gotten hard and brittle over time, they may be transferring more vibrations through the subframe into the cabin.

The lower front mount does little for engine vibration into the cabin unless your motor really vibrates more than normal, and is used to restrict motion backwards during acceleration. The same for the upper mount, but that one translates the most vibrations into the dash area since it's so high up and connected to the shock towers (worse if you have solid 'strut tower mounts' or PU inserts). The lower passenger mount is the one that probably fails most frequently.

 

I actually did a test. While the engine running and car in Park, I removed the bolt of the upper torque mount, effectively removing it from the equation. This according to my gf caused more vibration to be transferred in the cabin. I interpret this to mean that it actually reduces them, which leaves only the lower right mount as the likely culprit. It's the closest mount to the source of vibration - the crankshaft.

The vibrations are felt through the steering wheel, the seats, the door panels buzzing and in the foot area.

In my country its standard practice to rollback the odometer and make the car appear low mileage. I wouldn't be surprised if its close to 300k miles. And I doubt 300k mile engine mounts will be any good. Anyway, the Hutchinson mounts have arrived so...I have to change them out sooner or later.

But, like I said before, with all else being the same, it's either the upper mount and the lower right engine pad that could cause this. Funnily enough, the original lower right mount was so busted, I honestly wonder if it did anything but slightly keep the engine from falling down and yet vibrations were much better in gear than they are now(in Park mode no less) with the brand new Corteco ones.

From the research I have done, the reason some mounts transfer more vibration than others is largely due to the Shore scale of the rubber. Higher duro rating equaling more vibrations. And its a no-brainer from all of this that Corteco used rubber(or neoprene) with a higher Duro rating than genuine volvo.

EDIT: So what I plan to do is put back the original in and note the vibrations if they are increase or decrease. Second thing I have planned and will probably sound crazy, but has been bugging me for a while, is to experiment with adding a custom mount there with hydraulic fluid. Custom being a bracket and the actual mount being the fatty OR if I can find a different hydraulic mount. Usually engine mounts are tuned to specific frequencies(or so they say) and the location being chosen based on a number of criteria, obviously different engine mounts server a different purpose. Regardless of this, it's a nice experiment to try. I also really really like the idea of adding an active motor mount and have it be controlled by an external device.

 

I had same experience when changing the lower left engine mount (I have a manual gearbox - and it is that mount by the gearbox that creates my problem) The old mount is almost shut - but the thinner part of the mount (the end that connects to the gearbox) is still not totally shot - and very loose. I bought a Lemförder one - and when installing it an annoying vibration started in the cabin - mainly at idle - but I can also feel it when accelerating - just not so much. If I put slightly more rpms in idle in neutral - the vibrations go away. I found this video on youtube where a guy compares the original Volvo mount - with an aftermarket one - and the difference is extreme. The original Volvo one seems waaaay softer than the aftermarket ones. The one I got from Lemförder (and also another one from another aftermarket brand) are exactly as stiff as the one shown on the video (the not original one shown in the video) It seems the rubber on the thin part (that goes on transmission) is too hard on the aftermarket ones. (I will post the youtube link in next reply as not allowed to post link in first post on forum) On mine - if I remove the two bolts (either on the subframe or the gearbox) and start the engine - then the vibrations are gone in the cabin - and when I tighten the bolts with the engine running - vibrations at idle is back. Question now is if the original mounts are still as soft as the ones in the video - or if the original Volvo mounts have also started being fitted with the harder rubber on the thin part of the mount....? (As I understood it in this thread - the lower left at transmission had been changed with an original Volvo mount so I am curious if that mount is as soft as in the video)

 

This is the video comparing the mounts

 

It is now an old post, but I would like to chime in with an update. The upper torque mount Corteco failed within 2000 or so miles. As for the video in question, the original Volvo torque mount is much softer, the bigger bushing in the video barely flinches, whereas the Volvo genuine one has a lot of play, as it is soft.

Hutchinson for the upper torque mount are not available, so beyond Volvo genuine not a lot of options left.
