XC90 Top Engine Mount Replacement

dd1898 · Jul 31st, 2010, 16:57

First thread on here so please go easy.
I replaced the top engine mount on my XC90 today and thought I would post the procedure.

Remove the engine cover.
Remove the through bolt on the mount (15mm socket for bolt head and 18mm socket for nut).

Remove the right hand side restraint as it makes it easier to remove the mount (17mm socket for the bolt head and 18mm socket for the nut) and swing it towards the front of the engine compartment (not too much as it is still restrained on the left hand side).
Picture 2.jpg

Remove 3 off studs (14mm socket) and 2 off studs (10mm socket) from the mount and lift the aluminium block out.

Here are the two mounts side by side. Hopefully the new one is a little bit sturdier.

Reverse the procedure when fitting the new block, the Volvo mechanic said that the studs holding the block down should be set to 50 Nm (36.8 ft/lbs).

Here is the new block in position.

Took no more than 30 mins to do.
The new mount cost £55 and the part number for mine is 30776354 (Engine Anchorage).

Hope this helps some of you who are unsure about tackling the basic jobs on your car.

How old is that engine mount? I thought they'd all have been replaced by now. Thanks for the photos.

Sorry for the late reply, I went on holiday the next day.
The mount is the original one (2004), the rest appear ok so have left them.

Can I ask what the simptoms of a failed top mount are?

Vibration... cracking exhaust due to movement?

Thanks

David

To be honest I did not notice any symptoms prior to changing and have not felt any difference after it was just that I noticed that the rubber was split nearly all the way through and knew that it should not be that way. Having looked on other posts people were talking about steering wheel vibrations or uneven engine movement, I for one could not afford that problem so a new mount was the easy fix.

Thanks for the quick reply.

As a new owner, I must say that I was surprised to feel vibes from the steering wheel on mine at idle... and did wonder if something was up.... could this be it!?!?!

Thanks great thread really found the photos a big help and the spanner sizes saved me having to get out loads of kit. My mount was completely torn and only took 15mins to replace thanks to your clear instructions. regards phil rich.

Thanks for the post - saved me over £70, bought the part for £36 from a volvo dealer selling on ebay, and spent 25 minutes following your procedure - the 18mm nut was a challenge getting to with my socket drive but got there in the end! Was quoted £129 for it by Lancaster Reading!

Im wondering if any of my engine mounts are knackered, Ive only owned my '04 D5 for a month now and love it. Started to notice a vibration under acceleration, enough to be able to feel through the pedals and to blur the rear view mirror!
