Replacing an Engine Mount.

Introduction: Replacing an Engine Mount.

About: As of April 2017 I have decided to no longer post on instructables. The fact that several of my published works have been removed without my consent is inexcusable. Also the insult of an author having no co...

A couple months ago I replaced all the engine mounts on my Honda Civic 1999.

During the replacement of my Timing belt, the main engine mount got busted when I torqued the nut on the rubber mount's bolt. The Honda manual called for 74Nm but the bolt spun freely after 50Nm. Must have been a poor quality mount but from now on for that bolt I will not cross 40Nm!

Read on for how I replaced the busted mount in less than 20 minutes!

Step 1: Supporting the Engine.

Using my OEM car jack, I supported the oil sump using a piece of wood as a buffer.

Step 2: ‚ÄčRemoving the Busted Mount.

Removing the (3) 14mm bolts and (3) 17mm nuts, I took out the bogus mount. You can see the cracks on the rubber damper.

Step 3: Comparison.

Here is a side by side pic of old and new. The new one came with a lock washer and nut which I didn't bother to use.

Step 4: Installing the New Mount.

Putting in the replacement was straightforward. Once I torqued the nuts and bolts (the 3 bolts and mount nut to 40Nm, the two 17mm nuts to 60Nm), I removed the support jack and the job is now complete!
