How do you change the serpentine belt on a 2007 Pontiac vibe?

Answer 1

There is a big difference between a TIMING BELT OR CHAIN and a MULTIFUNCTION SERPENTINE ACCESSORY DRIVE BELT. The Timing Belt or Timing Chain is inside the engine and cannot be seen. Some cars have a rubber belt (many Japanese vehicles) that has a limited life, such as around 60,000 to 80,000 miles. It takes 2 -3 hours or more to change it because many parts have to be removed, sometimes the radiator. If it breaks, in some cars, one of the pistons will hit one of the valves and bend it, and this type of engine is called a "valve bender". Fixing a bend valve is very expensive. Many cars have a steel timing chain (many USA vehicles such as Chevy, Pontiac, and others). The steel chain is good for the life of the engine. They usually don't break, maybe 1 in 500,000 vehicles. God bless America and vehicles that are MADE IN USA.
