Change your Mazda MX-6 Timing Belt every 60,000 miles to avoid major engine damage. You may want to change the Mazda MX-6 Timing belt tensioner and idler pulley at the same time.
The Mazda MX-6 timing belt tensioner should be replaced along with the timing belt every 60,000 miles or at the manufacturers recommended replacement mileage. The Mazda MX-6 timing belt tensioner keeps pressure on the timing belt so the timing belt does not jump teeth and cause damage to the Mazda MX-6 valve train. The timing belt pulley and the bearing should also be replaced at the same time.
