Change your Porsche 924 Timing Belt every 60,000 miles to avoid major engine damage. You may want to change the Porsche 924 Timing belt tensioner and idler pulley at the same time.
The Porsche 924 timing belt tensioner should be replaced along with the timing belt every 60,000 miles or at the manufacturers recommended replacement mileage. The Porsche 924 timing belt tensioner keeps pressure on the timing belt so the timing belt does not jump teeth and cause damage to the Porsche 924 valve train. The timing belt pulley and the bearing should also be replaced at the same time.
