What is a Timing Belt?

Timing belts are a crucial part of a vehicle’s engine and drivetrain. Many Loudoun County and DC Metro area drivers know that much. But what is a timing belt, exactly? What does it do? Essentially, timing belts, sometimes called cambelts (along with timing chains in engines with larger bores and strokes) play a critical role in how internal combustion engines work. Timing belts ensure that camshaft and crankshaft rotation are in sync, which in turn allows engine valves and pistons to operate normally. Ready to dive deeper into the curious world of timing belts and internal combustion engines? The MINI of Sterling service pros are here to help! 

How Much is a Timing Belt? 

If your MINI timing belt breaks in Dulles Airport or Loudoun County, then what will happen is your engine’s valves won't be able open and close at the correct time. The vales will then hit the pistons and the car will need very expensive repairs — we’re talking up to $2,000+ if the valves, water pump, and pistons were damaged. This is why most manufacturers recommend replacing the belt every 60,000 miles to 100,000 miles. Looking for a way to save on MINI maintenance in Sterling, VA?

Signs Your Car Needs a New Timing Belt

Wondering when it’s time for a new timing belt? These are telltale signs that it could be time to replace this critical engine part:

• The engine misfires 
• More smoke and fumes than normal 
• Oil leaks from the front of the motor 
• Ticking noise coming from the engine 
• The engine won't turn over 
• The engine acts up between 2000 - 4000 RPM 

Timing Belts vs. Timing Chains: What's the Difference? 

Timing belts and timing chains have the same function. The major difference is what they're made of and where they're located. 

Timing chains are constructed of metal, while timing belts are made of reinforced rubber. Timing belts are generally much quieter than chains and can be found on the outside of the engine. 

Timing chains are normally found inside the engine and use engine oil for lubrication. In recent years, upgraded timing chains that operate quietly and with little vibration have made a comeback and can be found in a wide range of vehicles.
