What is a Cambelt?
A cambelt, also known as timing belt, is a crucial component in an internal combustion engine. It synchronizes the rotation of crankshaft and the camshaft, ensuring that the engine's valves open and close at the correct times during each cylinder's intake and exhaust strokes. Without a properly functioning cambelt, the engine would not operate efficiently, leading to potential damage.
History and Evolution of Timing Belt
Cambelts have evolved significantly since their introduction. Initially made of rubber, modern cambelts are reinforced with materials like fiberglass or Kevlar to increase durability and lifespan. The shift from chains to belts has allowed for quieter engine operation and more efficient performance.
Function of a Cambelt
The primary function of a cambelt is to maintain precise timing between the engine's components. It ensure that the camshaft and crankshaft rotate in unison, which is essential for the engine's valves to open and close in synchronization with the pistons. this precise timing is crucial for optimal engine performance and fuel efficiency.
Significance of Timing Belt in engine efficiency
A well-maintained cambelt contributes to the overall health of the engine. It helps in reducing engine noise, improving fuel economy, and minimizing emissions. A worn or damaged cambelt can lead to poor engine performance, increased fuel consumption, and potentially severe engine damage if not addressed promptly.
How often should you change your Cambelt?
There’s no ‘one size fits all’ rule when it comes to how frequently a cambelt should be changed, as a lot depends on the car. Most manufacturers suggest either a time- or mileage-based change, depending on which comes first.
There’s a lot of variation between both manufacturers and engines when it comes to when a change is due. This could range from 60,000 miles up to 100,000 miles, and from four years up to ten years.
The vehicle handbook will specify the change frequency, but if reading that is about as much fun as reading a bottle of bleach, then phone Cartopia GDK on 02033842999 and we'll be able to let you know if and when a cambelt change is due.
Manufacturer’s intervals should be treated as the absolute maximum, as failure of the cambelt can cause serious mechanical damage.
what's the price for getting a cambelt changed?
The bill for changing a cambelt can vary from around £350 to over £600 depending on the make of car, whether you want us to use genuine or aftermarket parts and it is also common for the water pump (the thing that pumps coolant around the engine) to run off the cambelt as well. In these cases it is always advisable to renew the water pump as well because if you have problems with the water pump in future you will have to do all the work again to get to it. The parts aren't hugely expensive, even genuine manufacturer parts, however it is just one of those jobs where it’s the labour that bumps up the bill.
Replacing the cambelt kit (that's what it's actually called) will take several hours of work, which involves taking apart the engine block and putting it back together.
Sings that my timing belt has failed
Again in a nut-shell, Nope.
Often there’s no sign the cambelt’s reached the end of the road as it’s so deeply embedded in the engine.
Ruben Almeida, our senior technician at Cartopia GDK with over 20 years experience, says: “If a driver is very lucky, they may hear a rattling noise but in most cases even an expert may not be able to predict a cambelt failure, so prevention is always better than the cure”.
And unlike new brakes or other replacement parts, you may not notice any difference in the way your car drives.
How to avoid changing your Cambelt?
Cambelts are often referred to as Timing Belts, because of the way they control the timing of the engine, but to avoid the dreaded cambelt change you could buy a car that's chain driven. Cars with Timing Chains instead of Belts don't need their chains changed but before you run out and Part Exchange your belt driven car for a chain driven one, you should know that it doesn't mean they're necessarily better. Chains stretch and repairs on that can be very costly too.
Seriously don't get me started on the BMW Vanos system !!!!! In fact if you have a 1.6 petrol BMW from 2004 to 2008 then you do want to be part exchanging that. :)
Maintenance Tips
Regular maintenance of the cambelt is essential for longevity of your vehicle. Here are some tips:
. Regular Inspection: Check the cambelt for sings of wear and tear every 30,000 to 50,000 miles.
. Follow Manufacturer Recommendations: Replace the cambelt according to the manufacturer's schedule, typically between 60,000 and 100,000 miles.
. Professional Service: Always have a professional mechanic inspect and replace the cambelt to ensure it is installed correctly.
FAQs About Cambelts
How Often Should a Cambelt be Replaced?
The replacement interval for a cambelt varies by vehicle and manufacture. Typically, it is recommended to replace the cambelt every 60,000 to 100,000 miles. However, always refer to your vehicle's owner manual for the specific interval.
Can I Replace a Cambelt Myself?
Replacing a cambelt requires a high level of mechanical skill and specialized tools. it involves disassembling significant parts of the engine, which can be challenging and time-consuming. Incorrect installation can lead to severe engine damage. it is advisable to have a professional mechanic handle cambelt replacement to ensure it is done correctly and safely.
