What drives the auxiliary belt?

Auxiliary belts are used to drive the air-conditioning compressor, power steering pump, water pump and the alternator, and are connected to those components from the crankshaft pulley. The auxiliary belt should be checked every once in a while to make sure the tension between pulleys is correct.

Beside this, is a drive belt the same as an auxiliary belt?

You will often find it referred to as the drive belt, the auxiliary belt, fan belt or in some American literature, the serpentine belt. They are all essentially the same thing, a belt which drives all the ancillary components such as water pump, air conditioning and alternator.

can you drive without an auxiliary belt?

Consequently, what happens if auxiliary drive belt breaks?

That means when your belt breaks, slips and, ultimately, wears out, everything—from the power steering pump to the alternator and air conditioner—stops working. What's more, the parts it controls can become severely damaged. Broken hoses and belts are bad; a damaged engine is even worse.

When should I replace my auxiliary belt?

Serpentine belts, which are much more commonly found in cars these days, are designed to last much longer then their predecessors. You shouldn't need to replace them more than every four or five years or every 60,000-100,000 miles.

Why is a serpentine belt better than V belt?

Serpentine Belts vs. V-Belts. Serpentine belts are used in new vehicles due to the fact that they are easier to maintain and are less complicated to install. The thicker multi-rib design of the serpentine belt provides a better belt to pulley contact ratio that creates less slippage.

Can a bad serpentine belt cause check engine light?

A loose or worn belt will cause ticking or rattling noises, poor engine performance and overheating, usually triggering the check engine light. If the timing belt breaks, the engine can't run — and on some engines that break can cause internal damage.

What causes a serpentine belt to slip off?

Slipping can be the result of a loss of belt tension (or a weak automatic tensioner) or pulley misalignment. When the belt slips off the track, the friction between the belt and accessory drive pulleys causes the belt to overheat.
