Remove the bolts that secure the lower timing belt cover in place and remove the cover from the vehicle.
Turn the engine very slowly and align the timing marks on the crankshaft with the marks shown in the picture.
NOTE: If the belt in your vehicle broke and you feel that one of the pistons may be touching a valve as you turn the crankshaft STOP!, and come back to align the marks on the crankshaft after you align the marks on the camshafts.
Turn the camshafts very slowly in a clockwise motion with a wrench, if you feel that one of the valves may be touching a piston as you turn the camshaft, stop and proceed to turn the camshaft in counterclockwise motion till you have aligned the timing marks the way is shown in the picture.
Slide the sensor attached to the front of the engine mount off.
Before you attempt to remove the front engine mount, place a floor jack with a piece of wood on top of it under the oil pan to support the weight of the engine as you remove the engine mount, the floor jack will need to remain in place till the engine mount is installed back on the vehicle.
Remove the 3 bolts that secure the front engine mount to the body of the vehicle.
Remove the upper bolt ( shown in image ) that fastens the front engine mount to the bracket mounted on the front of the engine, remove the second bolt and nut and remove the front engine mount from the vehicle.
Remove the bolts that fasten the front engine mount bracket to the engine and remove the bracket from the vehicle.
To make the belt installation much easier, you will need to use 2 allen wrenches as shown in the picture, one to turn the timing belt tensioner away from the belt, and a second smaller allen wrench to keep the timing belt tensioner in its locked position.
Install the new timing belt starting on the crankshaft sprocket in a counterclockwise manner followed by the water pump, idler, camshafts and last the tensioner ( shown in the image).
Once the new belt has been installed double check to make sure that the timing marks on the crankshaft sprocket and the camshafts are aligned properly, if they are, proceed to remove the allen wrench from the timing belt tensioner to allow it to work, turn the engine slowly by hand two full revolutions and check the alignment marks one more time.
This is how the alignment marks on the camshafts look like with the new timing belt installed.
Install the remaining components in the reverse order you took them off, make sure that you use a suitable harmonic balancer installer to install the crankshaft pulley back on the engine, failure to install this pulley the right way may result in damaged crankshaft threads.
Once you are done, start the vehicle, if there was no piston to valve contact during the timing belt failure the engine should run smoothly, however, if the engine is running uneven or it seems to have a miss, you will need to perform a compression test on all 4 cylinders, if any of them doesn't have compression or its compression is below 100 psi, it will be necessary to remove the cylinder head and replace the damaged valves to cure the problem.
