TIMING BELT REPLACEMENT
Your timing belt is a crucial part of your engine's performance and is the one part that can cause possible major damage instantly when it breaks. This belt allows the crankshaft to drive the camshaft, which in turn opens and closes the valves. Without the timing belt, the engine can't run.
You should replace the timing belt when your manufacture recommends a replacement. On many cars this is around 60,000 miles. Be sure and remember that this also means that it needs replacing again at 120,000 and 180,000 and so on.
Many modern cars have interference engines. If a timing belt breaks or jumps a notch because it is too loose in an interference engine, then the result will be $$$'s or even result in a destroyed engine--costing thousands. So you shouldn't try to "get by" and hope it doesn't break---CHANGE IT AT THE RECOMMENDED INTERVALS.
Be sure to find out from a professional if you have an interference engine. If you don't have an interference engine, then the worst thing that may happen is your car stops running, leaves you stranded, requires a tow to your local shop for a timing belt replacement, which causes major inconvenience, but at least your engine is not destroyed.
Your professional technician should check your timing belt for signs of wear, such as cracks or lack of tension. He should also check for signs of oil leaks from adjacent seals that could damage the belt and shorten the life of the belt.
We have had many vehicles in our shop that did not heed these words of advice and to our sorrow they have destroyed their engines , resulting in a useless vehicle. Not many customers at this point can afford upwards of $3000 for a new engine. So save yourself some possible grief and heed the timing belt replacement intervals. See our BLOG
