Volvo Repair Database How to replace lower motor mount?

Post by Zuffie88 »

My mechanic tells me that I need to replace my lower front (passenger side) motor mount, and that I can do it my self (I do most of my P.M.). My car is a '98 V-70.

Can anyone list the steps to accomplish this?

Thanks,
Zuffie

I just did this job on our `98 S70 a few weeks ago. Not hard at all.

1. Raise the front and remove the rt. ft. wheel. Use a jack stand since at one point you will be getting under the car. Remove the small screw that holds the top of the triangular vinyl flap in the wheel well, fold it up, and secure it with a clamp or small vise-grip. You will now have easy access to the mount.
2. Cut a 2X4 to the proper length to just overlap the edges of the sides of the oil pan. Place the 2X4 flat across the oil pan just behind the oil filter and use a hydraulic jack to apply slight lift to the engine using the board to protect the oil pan.
3. Break loose the 14mm bolts that attach the mount to the engine.
4. Remove the 17mm bolts that attach to the frame. Use a six-point socket with a breaker bar. The rt. bolt may have a clearance problem. If so, remove the 14mm bolts and raise the engine just a little more so you can get the socket onto the rt. bolt.
5. Install the new mount with the 14mm and 17mm bolts but don't tighten them down yet.
6. Let the engine down and remove the jack.
7. Tighten all the bolts. This time use a 17mm box-end wrench to tighten the rt. bolt.
8. Reattach the flap, put the wheel back on, car on the ground, and you're good to go. :)

I am slightly confused on this. I was told I needed to replace the front engine mount, this is the one in the front center of the engine correct? Do I use the same sequence as stated here?

Corrections - This article should be called the "lower passenger side engine mount" . The "lower passenger side (right) engine mount" is a simple rubber bumper and rather easy to replace.

The actual "lower front engine mount" on the V70 is hydraulic. The actual "lower front engine mount" replacement procedure is quite different from the "lower passenger side engine mount" and much more complicated. Access to the lower front hydraulic mount is highly obstructed by the starter bendix and other frufrafra.

The lower rear mount is also hydraulic on the V70. All of the mounts are actually engine and transmission or engine/trans-axle mounts since the engine, transmission, and differential are a single integrated block on these cars.

Front is on the passenger wheel side because our engines are turned sideways in the engine bay. There is no true rear engine mount unless you count the oblong tranny to engine mount on the "front side" closer to the driver's side

Actually, the above diagram shows the Front for FRONT of the CAR, and not front side of the engine. The mount labeled 9135178 is at the front of the engine due to the transversed engine. Hope this didn't confuse everyone too much.

Replacing the motor mount on the passenger side of the car is a fairly easy process. I had some trouble with some snapped bolts, but I took care of that.
Here are the instructions I followed:

Yes.
The front of the engine is as MadeIn Japan said. . . the end where the timing belt is located. The hydraulic side mounts far outlast the rubber front mount.

digging up this old post...

Besides the "front" mount, do any of other lower mounts commonly fail? I have replaced the trans torque mount and my upper mount is fine (I have a spare in case it goes bad). Are there any below that are common failures? I have replaced everything suspension related except the in the lower engine mount world. I have to do a bunch of work next month and want to add these to the list, but I'm not sure what to look for besides the front mount failure.

Also, what brand are recommended, are scan-tech to be avoided on these parts?

many thanks

I've got excessive movement of the engine despite a new Volvo brand front motor mount. The rubber on the Volvo mount is very soft. It might have been a defect. So I'm looking for a good replacement. FCP Euro offers Febi ($35) FEQ ($52) and Lemfoerder ($79). Anyone have experience with any of these, or know of their relative firmness?
