You may not have given a look at your timing belt until you heard a cymbals slapping each other; and then, the buzzer sounds off. Anything can go wrong when it’s time for timing belt replacement. Yes, even if you haven’t reached the maximum distance yet. Take a chance to see your timing belt and check for cracks, shredding, or excessive slack.
Apart from the natural symptoms which could wear up your timing belt, other factors that will affect its early replacement are oil leaks from surrounding seals, living in a dry climate where belts are worn rapidly, and infrequent driving (causes the belt to become a set shape).
These factors will lead you to replace your timing belt. If you don’t feel going to the mechanic and is more accustomed in doing your own repair, you’ll likely need tools that will help you do this.
The basic tools include socket set, torque wrench, combination wrenches, screw drivers, drain pan, jack and jack stands, and antifreeze. In addition to these tools, you will need more tools specifically designed for timing belt replacement. These include a new timing belt, timing belt cover gasket, timing light, belt tension gauge, and pins/bolts needed to hold camshaft position while working. For some vehicle whose crankshaft pulley doesn’t just slide off, a harmonic balancer puller or three-jaw gear puller will be needed.
Remember that in timing belts, it isn’t “one size fits all.” Tools, belt type, and procedure may vary depending on the vehicle’s model. Perhaps, the most valuable tool for replacing a timing belt is a manual from your car’s manufacturer.
