About the engine mounts.

Post by **Fuse** » 22 Aug 2006 06:54 pm

I have been thinking about buying a new engine mounts, those liquid filled thingies which will cost you and arm and a leg at the stealers...

Because I noticed that if the engine would go any lower the viscous fan would hit the surrounding plastics and that wouldn't be nice...

Mounts don't seem to be in a bad shape in otherwise because engine doesn't roll or anything, it just sits too low..

So I am asking that is it positive that if I buy those new mounts, the engine would sit higher? Or could there be any other reason why the engine sits so low now, I can't think of any but just to make sure.. I don't want to spend a lot of money just to notice that there is no difference.

I think I'm getting those "heavy duty" ones, even though I don't have a power steering.

And how big of a job is it to change those, can I do it easily on a parking lot with trolley jack and basic tools or is a car lift needed?

I noticed that the upper bolt/nut of the mount is in a kinda tricky spot because of the turbo but it seems that I can get a socket to fit in.. though of course I can always get the whole bracket out so the liquid thingy would come with it.

Its not a bad job to do, but you'll need good tools because the nuts that hold them on are very tightly screwed down.

Erm, yeah I did notice the engine in my blue GLE sits slightly higher than it did before, and I went for the heavy duty ones, which were about 30% more expensive.

In a post I put up a week or so ago, 650,000km in a 360 GLT (on the general discussion), there is mention (about 130,000km) of a repair technique to the engine mounts, drilling a hole and then filling with sikaflex, some liquid rubbery stuff. Does anyone know anything about this?

I called Volvo today and what a surprise.. "Part is obsolete" so those are no longer available. Wtf. I have to double check that though but if those really are not available anymore, then I have to figure out something else..

Anything new about the possibility of making a polyurethane mount? Would it work? I remember there was some discussion about it and Dai said he would look in to it. There wouldn't be no problem if the engine would sit on the mounts but as it is hanged on the mounts in 360.. Would the rubber or polyurethane mount hold?

If I can't get anything which fits I'll have to put some metal between the support and the body so I can get the engine higher.. Though that as a last option..

I have the same problem with my 360. My dealer told me that's the mounts are no longer available so are any aftermarket choice?

Thanks in advance.

I promised some time ago that i would measure the sizes of the mount. So Dai could see what he can do.

Here they are:

What i forgot to say; the left tread (right word?) with the rubber thingy is obviously worn troughout the years. That will be a bit shorter then the 3.6cm/1.42inch i guess, when you have a new mount.

Btw. what is the easiest way to change the mounts? Does the mounting brackets need to come out or is it possible just to undo bolts of the hydraulic mount and lower the engine, while the powerline is in place, as much that you can get the hydraulic mount out?

I think I have read that you can change them that way, but I can't say 100% sure...

Yet more parts no longer available. This is the sad effect of 5+ years of parts not being needed (having been replaced 5-10 years ago, or failures ignored due to age of car), and many cars suddenly suffering parts failures, only for it to emerge that parts have been discontinued due to a lack of demand. Nice...

Hello again.
This week I used the volvo daily and noticed that where the car is cold there's no hit of the fan but when more hot is the car it's make an ugly noise.

Would I change the oil in the mount? It's possible to disasembly the mount and repair it?

If anyone knows a way to fix the problem please let me know.

Thanks.

Assuming you mean the main cooling fan, it's supposed to get noisier as the car gets warmer. IIRC, it contains special oil which becomes thicker as it gets hot, not the opposite!

cheers

yup, i'm pretty sure that the oil in a viscous fan is supposed to get thicker as it gets hot, thus transmitting more drive to the fan, making it spin faster.

Most occasions I've seen of fans making 'ugly' noises is with electric fans, when the bearings start to fail and make really horrible noises! obviously this doesn't apply to a viscous fan, but it might well be worth checking that it's not fouling on anything?

The sound of the fan becomes when I drove the car but isn't continous, If the road it's in good state there's no "chunk" but if not good the fan hits in the plastic and when more hot is the car more hits...

I'm talking about change the oil in the engine mounts or a solution to mantain the engine a little higher to avoid the problem. I want to buy a new set of munts but I don't know where I could find it.

Thanks again and sprry for my (really) bad english.

oh please no there is no oil that actually gets thicker when it heats up...

the visco coupling works trough the expansion of the fluid, which actuates a mechanical clutch system.
