In your engine, valves over each combustion chamber open to allow fresh air in, close during the combustion event, and then other valves open to let out the exhaust. All of this happens over and over thousands of times a minute. The timing belt’s critical job is to make sure that all of this happens as it should – at precisely the right time. If the timing is off, your engine won’t run efficiently or maybe not at all – so a good timing belt is critical. If it should break, you could have costly engine damage.

Knowing how their engine works can help Brea drivers make informed decisions about car care and prevent pricey repairs to their vehicles. This is especially true when it comes to timing belts.
An engine’s power is generated in the cylinders. Inside the cylinder is a piston that moves up and down while the engine is running. Power is generated in a cycle that includes four strokes of the piston. First, the piston drops and a valve at the top of the cylinder opens to let in fuel and air. The piston then rises, which compresses the fuel and air. At this point, the spark plug fires, igniting the fuel and pushing the piston down. This downstroke transfers energy to the engine, which provides the power it needs to run. The piston rises again, and a valve opens to release the exhaust.
All of this movement is orchestrated by a timing belt. The timing belt is so named because it keeps the pistons and valves operating in synch with each other, just as a conductor keeps all of the instruments in an orchestra in time with one another. Thus, the timing belt is critical to the proper operation of your engine.
Not all vehicles in the Brea area have timing belts. Some have timing chains. A timing chain is more durable and rarely breaks, but timing belts are cheaper, so many auto makers use them to save money.
Timing belts wear out and break, so a vital part of preventive maintenance for Brea drivers is to replace the timing belt on schedule.
The results of failure of a timing belt depend on the type of engine in your vehicle, but they are always inconvenient and can be very costly for Brea drivers. If your engine is a non-interference engine and the timing belt breaks, the engine simply stops running. Now that can be an incredibly dangerous situation depending on where you are driving around Brea when it breaks, but it won’t cause any engine damage. On the other hand, if your vehicle has an interference engine and the timing belt breaks, the valves on your cylinders will actually fall into the path of the pistons. Then things start getting chewed up by the motion of the engine and it will cost thousands of dollars to get everything sorted out again. Compounding the problem is that there aren’t any warning signs before a timing belt breaks. A visual inspection of the belt is difficult also. In some vehicles, parts of the belt may be visible, but most vehicles hide the belt under a cover.
The timing belt doesn’t even have to break to cause major engine damage. If it slips, even one notch, the result could be engine damage with repair costs in the thousands of dollars.
Our only car care option is to simply replace the timing belt periodically. You can check your owner’s manual to find out how often your timing belt should be replaced. Many vehicles need a replacement at 60,000 miles, but the recommended replacement mileage could be as high as 90,000 or 100,000 miles. If your owner’s manual recommends replacement at 60,000 miles, however, don’t wait until 65,000 miles to get it done. Remember what you’re risking.
Replacing a timing belt is not a cheap part of preventive maintenance for Brea auto owners. The belt is usually difficult to get to and often requires removal of some of the engine accessories. The cost of the replacement, however, is a lot less than the repairs may cost if the timing belt fails.

Your engine is like a finely choreographed dance. All the parts have to work together. If the timing is off at the ballet, dancers crash into each other and fall down. It the timing is off in your engine, it may not run at all. One of the most intricate dances in your engine, has to do with the combustion cycle.
Your sedan engine has cylinders in which a piston travels up and down. At the top of the cylinders are valves open to bring in the air and fuel. And there are valves that open to let out the exhaust after the fuel has been burned.

It’s critical that the values be timed to open and close at precisely the right time in the combustion cycle, or the engine will run poorly or not at all.
The timing belt is responsible for rotating the shafts that control the valves. It’s vital and precision work. Timing belts are made of very tough flexible material. They can last a long time. But they eventually wear out and can break. The consequences can be disastrous.
In some engines, the valves actually protrude far enough into the cylinders that they could come in contact with the piston. If the timing belt breaks, the pistons will smash into the valves. Valves get bend or broken. If the engine is spinning fast enough, the broken parts will shred the cylinder head as well. Repairing this damage can cost several thousand dollars.
It’s a sad day when this happens; especially since it usually can be avoided. Manufacturers have issued recommendations for when you should replace your timing belt. For some engines, it’s at 60,000 miles. For others it’s at 90,000 miles or more. If you’re approaching 60,000 miles, or have passed it, make sure you check your owner’s manual or with your Brea California auto service advisor at Jax Auto Repair for when the timing belt should be replaced. Don’t let this one slip by.
Now some timing belts are visible and can be inspected. Others are hidden under a protective cover and are hard to get to. Some timing belts also drive the water pump. If you have a leaky water pump, the coolant will contaminate the timing belt and could make it fail sooner. So if you have this kind of engine, get it in to Jax Auto Repair for an inspection right away if you have a coolant leak.
Most people in the La Habra area with this engine design end up with a new timing belt when they replace the water pump. And when you’re having your timing belt replaced on schedule, check with your Brea California auto service advisor at Jax Auto Repair to see if it makes sense to install a new water pump, even if it isn’t currently having problems, since most of the labor is already being done any way for the timing belt replacement.
As a heads up; larger engines will often have metal timing chains rather than belts. The chains don’t need to be replaced like belts.
We’ve already told you how very expensive it can be to get your car running again after a timing belt fails. You also need to know that replacing the timing belt is very labor intensive and is one of the most costly maintenance services you will have. So if you will be at the point where your timing belt should be replaced in the next year or so, ask for an estimate from Jax Auto Repair in Brea California so you can begin to prepare for the expense.
