The timing belt broke on my 2001 ford focus 2.0 z engine how do I fix it
If you are technically minded, this job should take you about an hour or so, provided that you have the right tools for the job. The first thing to do is to expose the old timing belt by removing the plastic cover running down the full length of your engine from the top cover( where you fill up the oil) to the bottom, near the floor. To do this you may have to remove all the drive belts such as the alternator, power steering and air conditioner belts.
Next, place the car in 1st gear and ask some one to apply pressure to the brake pedal. this is to prevent the engine from turning whilst you loosen the bottom crankshaft pulley bolt, so as to gain access to the timing belt. This bolt might be VERY tight, in which case you need to stop the crank shaft from turning by holding the ring gear on the opposite side of the engine. To get to this you must first disconnect your battery and then remove the starter motor. You now need something like a large screw driver or tyre lever to place between the engine and the flywheel teeth to prevent the crankshaft from turning. Once you have loosened the front crank pulley bolt, you should remove the top engine cover to expose the cam shaft.
You now have to set timing, To do this safely, first remove all the spark plugs so that you can see when number one piston comes up to the top of it's stroke, Now remove the distributor cap and work out where the rotor is pointing and which spark plug is the next in sequence to get spark. remember the MOST engines rotate clockwise, when looking from the cam belt side towards the flywheel. to ensure that the valves do not ouch the piston when you turn the engine, turn the engine at the front crankshaft pulley slowly until the closest piston ( number one) is at the top of it's stroke. You can confirm this by looking for a mark on the front crankshaft pulley which should now correspond with a mark on the front engine cover. If there are a few marks on the cover, look for a zero (o) or TDC mark. Align the pulley mark and the front cover mark, Now turn the camshaft until number one spark plug will receive spark. Now take a close look at the camshaft pulley. There should be a mark of some sort to indicate that the camshaft is also corresponding to TDC.
You can now remove the front timing belt covers and remove the old belt. Now remember that the engine rotates clockwise, so therefore, there will be a tight side and a loose side to your cam belt. On the loose side there should be some sort of tensioning device. This must be locked out of the way to allow you to fit the new belt.Double check that your timing marks are correct and then place the new belt over the toothed pulleys with the tight side on the right, and any slack or free play on the left. Once the belt is in place, release the tensioner. Double check that the timing marks are still correct.
Replace the front covers and the top cover.
Replace the front crankshaft pulley and tighten. A few drops of locktite thread lock should be applied to the bolt before tightening. This bolt should be torqued to a factory setting of about 140 Nm.
It is a high tension bolt so do not be scared to make it as tight as you can. Replace all the belts, distributor cap and spark plugs and the job is done. Before starting the engine, turn the crankshaft by hand at least two revolutions to ensure that all is well.
