Does 2007 Lexus IS250 have a timing belt?
Your Lexus IS250 uses a timing chain rather than a timing belt. Just be sure to perform regular services on your car such as oil changes, tire rotations, and any other Lexus specific service intervals and you should be just fine.
When do I need to replace my timing belt?
If the belt lasted to its replacement interval, dependent on the make-and-model, the belt’s tensioners and the engine water pump would need replacing, too.
What’s the difference between timing belts and timing chains?
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. Unlike timing chains, timing belts eventually wear out.
How often do you change the timing chain?
Timing chains are maintenance-free and typically last as long as the engine. Mechanics generally change timing belts every 60,000 to 120,000 miles. Timing chains and timing belts connect the crankshafts and camshafts in four-stroke engines.
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 timing belts need to be replaced?
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. There are no prescribed timing chain replacement intervals.
How can I tell which timing belt I have?
The first step in identifying which timing belt that you have is to look for identifying numbers and/or letters marked on the timing belt. These numbers indicate a standard trade size and will help in identifying the specifics of the cog belt.
Does my Lexus have a timing belt or timing chain find?
Depending on the model it may be a slightly later year when the switch was made but for the most part you can expect that any modern Lexus is currently using a timing chain. As we said, timing chains and timing belts do the same job in your engine. The main difference is durability and materials.
What do timing belts and timing chains do?
Timing belts and timing chains perform the same function in the engine of your vehicle. They linked the crankshaft and the camshaft to ensure that they move in perfectly synchronous time.
