Why do cars use timing belts instead of chains?
Why do cars use timing belts instead of chains?
Auto manufacturers started using timing belts because they are much less expensive to manufacture and they run more quietly. They’ll stay tight without damaging much (like timing chain teeth for a timing chain), but when they go, they’ll go. The good news is that belts are much easier to replace than a timing chain.
Why do cars have timing chains instead of belts?
Since the timing chain is made of metal links, it must be constantly lubricated with engine oil. What cars have timing chains instead of belts? More and more cars are fitted with a timing chain. In general, Mercedes and BMWs are equipped with timing chains.
What kind of timing chain is used in a straight six engine?
Timing chains were the standard in almost all four-stroke engines until 1966, when Pontiac introduced its straight-six, overhead-cam engine design. The new design featured a timing belt made of rubber, instead of a metal timing chain. To give timing belts extra strength and durability, manufacturers often weave Kevlar or fiberglass into the rubber.
How often do you need to replace timing belts on a Toyota?
Some Toyota engines have timing belts, some have timing chains. It pays to know what your engine has. Belts need to be replaced at normal intervals (usually every 90-100k on late model cars) or you will have hell to pay. Timing chains however are a different story and will generally last the lifetime of the engine.
Why are timing chains used in overhead valve engines?
For decades, overhead valve (OHV) engines used timing chains or timing gears to rotate the camshaft. Through the 1980s, timing chains powered many overhead cam (OHC) engines. Timing belts were especially common from the mid-’80s through the ’00s, but timing chains are becoming more widespread again.
What model cars have a timing chain?
Manufacturers such as BMW, Opel, Volkswagen, Ford, Cats, Mercedes and many others equip many of their models with timing chains, and the main reason for this is that the chains are much more reliable, the risk of wear or tearing is minimal and they can withstand much higher loads than timing belts.
Can you start a car with a broken timing chain?
A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves. The valves themselves will bend and potentially ruin the engine.
What cars have a timing belt?
- Most BMWs
- Most Mercedes
- All Cadillacs
- Alfa Romeo 159
- Chevrolet Corvette
- Sandero Stepway
- Honda Jazz
- Mazda with Skyactiv-G engine
- All SAABs equipped with a turbocharged engine
Do Honda engines have a timing belt or a chain?
Some Honda engines are timing belt and others are chain . You need to know which one you have. A belt will need to be changed at regular intervals (usually at 90-120k miles) whereas a chain is generally good for the life of the engine and does not require maintenance.
