This was my first time replacing this so there may be some varying opinions on ways to get this done, but this should give anyone who has never done one a decent guide to getting it done quickly, efficiently and safely. Please read through this completely first, you may wish to do a couple of the steps I described in a different order such as removing the dogbones and jacking up the hub assembly. This took me about 30 minutes for my first time. My first step was to set the emergency brake. Then jack up the passenger side of the car and get it set on a jackstand. Then I removed the wheel. Next remove the cover in front of the a-arms that covers the harmonic balancer and AC compressor for access to the engine mount area. It is held on with three plastic retainers that you pull the center out of and then remove the base of the retainer. I have a panel tool that makes getting these retainers out a little easier, but it can be done with a flathead screwdriver. Here's the view with the cover out of the way. The "U" shaped bracket is what is attached to the engine and sits on the mount. You can see the two upper studs of the mount going through the bracket and the mount directly below. Now remove the two 15mm nuts on the two studs that go through the engine bracket I mentioned. You may have to use a wrench to get these off, I just happened to have a very shallow 15mm socket that allowed me to get them off with a ratchet. Next, from under the car, remove the two 15mm nuts that hold the mount in the cup on the frame. There is one in front and one behind the cup that the mount sits in. Next I removed the 2 torque struts (dogbones) on the top side since we will have to jack up the engine off of the mount. If you've never had these off, they consist of two 15mm bolts through each dogbone with a 15mm nut on each bolt. 4 bolts, 4 nuts total. After the dogbones were removed, I placed a short piece of 2x4 across the oil pan and transmission pan and placed the jack between the two on the 2x4. I used the 2x4 to keep the engine level while I was lifting it with the jack. We are only lifting the engine here, so this will support the weight no problem. I think it goes without saying, but DO NOT use this as a lift point to jack up the entire car, ever. Also, do not start jacking this up without removing the 4 nuts completely from the engine mount. Failure to do so will more than likely crush your oil and/or trans pans. When I started lifting the engine, I realized it was putting a pretty severe angle on the halfshaft, so I went ahead and jacked up the hub to reduce the angle of the half shaft to avoid any damage. Two jacks came in handy, but you could do this before you get started and place the hub on a jackstand. With the hub supported, I continued jacking up the engine until I had enough clearance to remove the old engine mount. You may need a small prybar to free up the mount. Now, with the old mount out of the way, I suggest cleaning up the inside of the cup that it sits in. It tends to catch small rocks and other debris that you don't want getting in the way when you put the new mount in. Once it's all cleaned out, set the new mount in the cup and SLOWLY let the engine down. You will most likely need to use a prybar to shift the engine around the get the holes in the engine bracket to line up with the two studs on the top of the mount. I let mine down until I had just slight pressure sitting on the studs then shifted the engine around with the prybar until the studs popped into the bracket on the engine. I got one stud slightly in the hole and then I pryed only on the engine mount bracket with the prybar against either side of the large cradle bolt you can see on the right of the picture below until the other stud popped into place. Once they are lined up, let the engine all the way down onto the new mount. Now replace and tighten all 4 of the 15mm nuts on the mount, 2 on top, 2 under the car. You can now let down your hub assembly and reinstall your dogbones on top. Also reinstall the plastic cover and three retainers you removed over the pulleys. Put your wheel back on and get your car down off the jackstand. That's it, all done! Here is the solid rubber engine mount I got from Autozone. The solid one is only available from them online. See this thread for more info including part numbers and ordering info for this mount: http://www.grandprixforums.net/f79/autozone-solid-engine-and-trans-mounts-4219.html
Here is the new solid one in front of my old worn out hydraulic one. There is probably close to half an inch of drop in the old blown out one versus the new one. Feel free to ask any questions if you run into anything I didn't cover and I'll do my best to help out. | |||||||
