If you're looking for a new timing belt, there are a few things to consider. Firstly, you need to know what type of vehicle you have. Different vehicles use different types of belts. Secondly, you need to decide which material you want your belt to be made from. The three most common materials are neoprene, polyurethane and polyester. Each has its own advantages and disadvantages.
Neoprene is the most popular choice for timing belts. It's strong and durable, making it ideal for high-performance engines. However, neoprene can be susceptible to stretching over time, which can cause the belt to slip or break.
Polyurethane is another popular choice for timing belts. It's less likely to stretch than neoprene, so it doesn't need to be replaced as often. However, polyurethane belts can be more expensive than neoprene belts and they're not as widely available.
Polyester is the least popular choice for timing belts but it has some advantages over the other two materials. Polyester is very strong and resistant to stretching, making it ideal for high-performance engines.
