Belts and Hoses

What Do Belts and Hoses Do?

They move all the parts of your Nissan vehicle that are supposed to move. Belts move things mechanically (in other words, using other parts), while hoses move them hydraulically (i.e., using liquid pressure).

What Types of Belts are There?

Serpentine, drive (also called V-belts), and timing.

Serpentine and drive belts move parts in the AC system, for instance -- those like the compressor. They also move alternator, power steering pump, and other parts. Timing belts, however, help the crankshaft and camshaft turn properly, opening and closing the engine valves at the right intervals and the pumping of the engine pistons in the process.

What Types of Hoses are There?

There are many, for everything from the radiator, heater core, and fuel system to the brakes, air induction system, and more.

Radiator hoses, for example, move coolant (also called antifreeze) between the engine and radiator. Heater core hoses, on the other hand, send hot coolant through the heating and air conditioning system to help warm the cabin. Fuel hoses connect engines and gas tanks in older Nissan models.

Brake hoses, though, send brake fluid to the brake calipers. Air intake hoses, in contrast, help the engine regulate its oxygen and fuel levels. There are even hoses for things like oil coolers and PCV (positive crankcase ventilation) valves.

What are the Symptoms of When They Go Bad?

For one, you may be unable to start your vehicle. Also, it may not run right, or it may end up disabled completely. Most often, though, its belts and hoses will appear visibly loose or obviously damaged, and you may hear screeching or chirping sounds. You may also see leaking fluids and battery and lighting malfunctions, and your engine may misfire or overheat. Finally, many systems may start failing generally.

How Often Should They be Changed?

Review your owner's manual for the answer. It should contain info on mileage limits. Most hoses, however, get replaced every 4 years or so. Before buying new belts or hoses, though, be sure they're genuine.

Why Buy Genuine OEM?

Nissan manufactures its belts and hoses to spec for your model -- car or truck, SUV or van. That essentially guarantees compatibility with it -- a promise that the aftermarket may not always make.
