In this modern era, many vehicle owners are becoming more and more savvy about vehicle maintenance and repair. But, timing systems, crucial to good engine performance, are still a mystery to many people. Here is a short "primer", nine important facts to know and understand about timing systems:

1. A timing belt, timing chain or cam belt is a part of an internal combustion engine that synchronizes the rotation of the crankshaft and the camshaft(s) so that the engine's valves open and close at the proper times during each cylinder's intake and exhaust strokes. (Wikipedia)
2. A timing belt is a belt that usually features teeth on the inside surface, while a timing chain is a roller chain. (Wikipedia)
3. Since timing chains and belts serve to synch the motion of the crankshaft and piston position with the cam shaft, maintaining these will avoid major mechanical failures and help to avoid serious repair bills
4. A great many vehicles, especially those built in the last decade, might utilize a timing chain for timing the camshaft and valves instead of the timing belt that had been standard on older cars.
5. Despite the fact that timing chains are much more stronger than older timing belts, they can still break down and be the cause of catastrophic damage.
6. A high percent of cars that use timing belts, instead of chains, are known as interference engines. That means that the valve and the piston occupy the same space at different times. At any given time, there is always at least one or two valves that are at full extension.
7. If your belt fails for any reason...water pump, idler bearing, etc. ...the camshafts will stop instantly. And, as you are rolling to the side of the road wondering what has happened, your pistons are still going up and down attached to the crankshaft, beating and bending the daylight out of whichever valves are still left at full extension when the camshaft stops (because the cam and the crank are no longer synchronized).
8. Remember folks, your timing belt should never be left in place more than 100,000 miles.
9. A good "check" is to look at the exposed serpentine belt, if it's never been changed, then the timing belt has likely never been changed.

So, your vehicle's timing system is a crucial part of your engine; your timing system is something every vehicle owner should have a basic understanding of. And, with proper care, your vehicle should serve you well.

Stop It! ...Good Brake Care

You should probably know that without good brakes, your vehicle would not be safe as you may not be able to stop quickly or slow down when you need to.  This may be especially bad when you are driving at higher speeds!  Here are a few tips that might help you:

1. Free brake inspections are available at many car repair shops.  Take advantage of this free inspection service that may be offered in order to secure your business.  They should check all your hydraulic fluids, brake pads and shoes, caliper and rotor wear along with checking your anti-lock brake system (if your vehicle has one).
2. Make it a rule to visit your regular ASE certified full-service mechanic shop so you can catch any problems early on and avoid costly repairs to a badly damaged system.  These kind of shops inspect all systems as a preventative measure for good maintenance practice and safe vehicle operation.
3. Learn to pay attention to the common signs that accompany brake problems like your vehicle pulling to one side when applying your brakes, a soft feel to the pedal, jerking when you attempt to stop, leaking around the wheels, strange grinding sounds or grinding noises, or your brake warning light turns on.

If you should have any of the warning signs or need your yearly brake inspection (and are in the Lake of the Ozarks area), call or stop by Gerbig's Osage Auto Service for quality service that is fast and convenient.
