Timing Belt: A timing belt must be replaced as recommended by the manufacturer intervals, usually from 60,000 miles to 105,000 miles (from 96,000 km to 168,000 km). You can find the recommended replacement interval in your owner's manual for replacemnt under ideal conditions. There are other conditions which you would want to replace your timing belt regardless of the miles.
A timing belt with cracks, is fraying, has cuts, or if it is soaked in oil leaking from the engine, or if it shows any signs of excessive wear.
Choosing to not replace your timing belt can result in the timing belt breaking. If you are approaching the mileage for a timing belt change, or if you bought a used car and you don't know if the timing belt has been replaced, it's a good idea to have MAKESTAR Automotive inspect the timing belt condition.
When timing belt breaks, the engine will no longer motivate the vehicle, stops all the sudden. If a timing belt breaks while driving in an interference engine, the camshaft stops turning leaving some of the engine valves in the open position.
A heavier crankshaft will continue rotating by inertia, moving pistons up and down. This will cause the pistons to strike the valves that left open. This may result in a heavy damage to the engine with broken or bent valves, damaged pistons and, possibly, destroyed cylinder head and block.
**Bottom line is if you ignore changing the timing belt, it could be a costly decision.
