Changing the Timing Belt -- Page 1

You can do the spark plug change near the end of this overhaul, or at the beginning. If you plan to change the timing belt, you may need the plugs and battery connected to "bump" the starter to loosen the crankshaft bolt. So do this first.

You need to expose the crank pulley for this first step. Support the front end of the car on jackstands, and remove the passenger side front wheel. This is also a good time to put a support under the engine (will need this later when you remove the front engine mount). I used a bottle jack to lift, and a smaller jackstand to hold it.


Then remove the wheel well shielding, as well as the plastic shield that covers the drive belts.

Disconnect the center plug of the distributor (comes from the ignition coil) so the engine won't actually fire.


Put a six-face socket on the crank bolt attached to a breaker bar or extension, preferably 1/2" size. Then turn the key for a few seconds, "bumping" the starter. This will engage the flywheel and turn the crankshaft, loosening the bolt for you. The crankshaft spins clockwise during normal operation, as it faces you in this picture


This is a top view of the crank pulley with the "bump" breaker bar in place. Note that on this engine, there is an overlay narrow v-pulley to drive the AC compressor (in a world where A/C is an afterthought ... ). The bolt on the small tensioner pulley (arrow) is loosened to remove this belt.


Now on to removing the drive belts, pulleys and motor mount.
