We have to Replace Belt all ?

Most vehicles have a plastic belt on leading of the engine unit that drives accessories including the air-conditioning compressor, vitality steering pump and alternator. If this accessories drive belt (also known as a V or serpentine belt) breaks, the power won't get priced, the air conditioning equipment won't blow cool air and the energy steering will venture out. Furthermore, if the belt drives the drinking water pump, the engine unit could overheat.

Most manufacturers demand regular inspection of the belt within planned maintenance, but few list a particular replacement period, and inspection intervals differ widely.

Mercedes-Benz, for example, says to examine the belt every 2 yrs or 20,000 mls, while Volkswagen says to check on it every 40,000 mls. Of all Ford vehicles, the maker says to start out inspecting it after 100,000 a long way and then every 10,000 a long way. On many GM vehicles, the first recommended inspection reaches 150,000 kilometers or a decade.

Though these belts often previous a long time, they may become damaged or frayed and have to be replaced. That is why they must be inspected at least on a yearly basis on vehicles that are lots of years old. Furthermore, if the belt must be substituted, the pulleys and tensioners that guide the belt should be inspected to ascertain if they triggered damage apart from normal wear.

A belt that's not damaged or frayed may appear to be it's who is fit, but grooves on the concealed aspect may be worn enough that the belt slips on the pulleys that drive the accessories. Which will cause problems in systems that count on the belt to keep things humming. For instance, a sliding drive belt could cause the alternator to work intermittently or at reduced ability, and the power supply won't get totally recharged because of this, perhaps triggering a caution light.

Another sign of the worn belt is a squealing sound under acceleration. Which could signify that the belt is sliding because of wear, a belt tensioner is loose or a pulley has gone out of alignment.

Modern vehicles use belts created from ethylene propylene diene monomer, a fabricated rubber that endures longer than more aged types of engine motor belts. Most belt manufacturers calculate the typical life expectancy of EPDM belt to be 50,000 to 60,000 a long way, plus some say it's more than 100,000 a long way. However, it could be hard in order to how worn one has been only a aesthetic check because EPDM belts are less inclined to split or lose chunks of plastic than other styles. They must be inspected by a specialist.
