Whether you're driving a Toyota or Scion, your vehicle has many moving parts. High-quality OEM belts and hoses help make sure they all move the way they're supposed to. Brake hoses, for example, move brake fluid from your brake lines to your brake calipers; this process charges your brake system. Air intake hoses, on the other hand, control oxygen levels in the air/fuel mix whose combustion powers your engine; this keeps the latter running right. Serpentine belts and drive belts, for another example, move systems like power steering, not to mention your alternator. Timing belts and timing chains, though, turn your camshaft correctly, properly pumping engine valves and pistons. There are plenty of other original belts and hoses at work under the hood, too, ranging from AC compressor belts to heater core and radiator hoses. Older Toyota and Scion models may even still have fuel hoses. Is your vehicle running badly or disabled? Worn belts and hoses may be the causes. Signs include visible looseness, damage, squeaking belts, leaking hoses, battery or lighting problems, and even engine trouble. Change belts according to mileage and your maintenance schedule. Replace hoses approximately every 4 years. Our online auto parts counter makes ordering both easy; we've got plenty of genuine belts and hoses in stock, straight from Toyota & Scion.
