If the timing belt failed while the engine was running the chance of valve damage is probable, therefore an engine compression test should be carried out after the belt has been replaced. In the removal process, do not revimplify the crankshaft or camshafts once the timing belt is removed so as not to cause valve damage from impact by the piston. First, remove the negative battery terminal, properly jack up the vehicle placing jack stands and then remove the right inner splash shield and the accessory drive belts. You remove the crank shaft pulley by slackening the center bolt of the crank shaft pulley, if it cannot be held still by hand you could use a large screwdriver or bar to do this, use a three jaw puller to remove the pulley with the correct insert to protect the crank shaft threads. Retranslate the lower and upper timing belt covers, replace the crankshaft bolt with spacer and take out the right Engine Mount by using floor jack. I will make sure that the camshaft sprocket and the crankshaft are aligned in the right manner before the timing belt is removed and if one is to reuse it, the direction of the belt has to be marked. Relax the tensioner pulley in order make some space then remove the timing belt, and check the crankshaft front oil seal, the water pump, the tentioner, idler wheel and the timing belt for any signs of abrasion or wear. Ensure that the timing notches on the camshaft sprockets are properly aligned, turn the exhaust camshaft sprocket in the anticlockwise direction and fit in the timing belt by creating tension. Allen wrench should be used to turn the tensioner and tighten the lock bolt; then rotate the crankshaft two full rotations clockwise, if it is tight this may mean incorrect valve timing. If required rearrange the timing marks and replace the belt and other parts in the reverse sequence making sure that the crankshaft pulley bolt is tightened to the right torque before starting the car for road test.

Unbolt the idler pulley and remove the engine mounting plate by taking out the retaining bolts.
