Belts and Hoses

Chances are good that the first time you opened up a hood to look at an engine, you were a little overwhelmed by the number of belts and hoses you saw.  Belts are responsible for moving the moving parts in the engine, while hoses transport liquids and air throughout the cars systems.  A belt or hose failure can bring your car to a stop and might actually cause serious damage to your vehicle.  That is why is it very important to regularly inspect belts and hoses and replace worn or damaged hoses before they become a problem.

Checking most hoses and belts is simple and can be done by even novice DIY mechanics.  While the steps are easy, it is important to realize two things; the engine should be off when inspecting them, and the engine should be cool.

Ideally, hoses should feel both firm and pliant.  If they have any bulges, collapsed sections, cracks, surface abrasion, or nicks, they should be replaced. If the hose feels brittle, it should be replaced.

Many newer engines are driven by a single multi-grooved serpentine belt.   This belt drives the alternator, water pump, power-steering pump, and air-conditioner.  However, older engines may have multiple belts, known as V-belts, which drive the accessories.  When inspecting these belts, you are looking for cracks, fraying, separating layers, missing chunks, and splits, but you are also looking for any spots in the belt that appear too-smooth or slick; a slick belt can slip.

Vehicles also have a timing belt, which rotates the camshaft and the crankshaft.  The timing belt may actually be a timing chain, depending on the age, make, and model of your vehicle.  Water pump, tensioner, and pulleys should also be replaced if you are doing a timing belt replacements.
