Belts and Hoses

There are a number of parts in your GM vehicle, many of which depend on either belts or hoses in order to operate their best. As a matter of fact, some even rely on both!

Types of Belts

The timing belt is a notched belt that helps turn your camshaft while ensuring that valves and pistons operate in sync. If you drive a newer model, however, it may feature a more durable timing chain instead. The serpentine belt teams with the tensioner, crank pulley, and idler pulley to move such parts as the alternator and power steering. Drive belts, which are more numerous, run off the crank pulley and help move your water pump and other parts.

What Hoses Do

Hoses route fluid to and from parts that need to be lubricated or cooled, such as the radiator and engine. The radiator sends coolant to the engine to prevent it from getting too hot, and then engine returns the fluid to the radiator to be cooled all over again.

How to Spot Issues With Your Belts and Hoses

Your owner's manual will detail your recommended maintenance schedule, though you'll want to make a regular practice of inspecting your vehicle's belts and hoses. Signs of failure include:

• Frayed belt edges
• Loose or slack belts
• Belts that are overly tight
• Cracked hose material
• Large pools of liquid underneath your vehicle
