The wires are part of the mount. The connector is between the white and green arrow. Just decouple it from the harness and the rest is part of the mount.
extra_informaiton: The mount is active mount and the electrical pulse counters the vibration.

Anyone know what is the torque spec for that 17mm bolts for the front engine mount? I had to loosen it to lift the engine up a bit so I can remove the water pump.
I want to tighten it back but I can't find the torque spec for that bolt.
Thanks!

Also, I removed the oil filter to make this process easier. I also used a 1/2 socket extension, so the rachet would be above the engine frame. Hope this helps.
Hi, the top bolt is also visible after removing the filter and looking through the manifold. Can you use an Impact wrench with an extension? Did you use a 17 mm swivel socket? Thanks.

Hi, I am in the same situation and can't get the mount out. How did you end you end up finishing this?
Thanks.

I just did this and I can say it wasn't as easy as it sounds but if you have worked on cars before somethings are hard. This one is difficult because you definitly have to remove the radiator. There is a good DIY article on how to remove the radiator. There isn't any other way to maneuver the mount out of the car without doing this.

As JohnLX300 mentioned the oil filter also needs to be removed.

The center 17 mm bolt still had some resistance to it so I was able to loosen it with a breaker bar. The other three 14 mm bolts are easier. Pay specific attention to how the connections are going into the mount as this is an active mount and moves up and down depending on the vehicle speed/idle. No need to remove the top dog mount. You only need to raise the engine a littlte to remove and install the mount. Do not go over board in raising the engine.

In putting the bolts back, the center one needs to go in first. Turn it about 1/2 way before putting the front bottom 14 mm bolt. Then put in the two side bolts. Don't tighten any of them just hand tight. Once the three bolts are in lower the engine and tighten the center bolt all the way then proceed to tighten the other three. Go over the center bolt once more to make sure it is tight.

Don't be discouraged if the center bolt doesn't turn easily even though it isn't in much. This means it isn't in place correctly. You'll need to start the above process over.

I also recommend changing the "Engine Torque Strut" if it has never been changed and your car like mine has over 200,000 miles on it. Four bolts and there you go. Put some penetrating fluid on the top bolts.

12361-20060 Engine Mounting, Front
12307-20021 Engine Torque Strut

Hope this helps someone and send me your questions. Good luck to you all.
