Belts and coolant system

Sooner or later your car’s engine accessory drive belts, timing belts, and coolant hoses will dry out and crack. Regular inspections, coupled with timely automotive belt and hose replacement will help protect against roadside breakdowns and expensive repairs.

Belt System:

  1. Drive Belts: Most modern vehicles have one or more serpentine belts that drive accessories such as the alternator, power steering pump, water pump, and air conditioning compressor. Inspect the belts regularly for signs of wear, cracks, fraying, or looseness. If you notice any issues, replace the belt(s) as needed. Typically, serpentine belts should be replaced every 60,000 to 100,000 miles, but refer to your vehicle's maintenance schedule for specific recommendations.
  2. Timing Belt: Some vehicles have a timing belt that synchronizes the rotation of the engine's crankshaft and camshaft(s). If your car has a timing belt, follow the manufacturer's recommended replacement interval, typically every 60,000 to 100,000 miles or as specified in your owner's manual. Failure to replace a worn timing belt can result in catastrophic engine damage.
  3. Tensioners and Pulleys: Along with the belts, inspect the tensioners and pulleys for proper tension and smooth operation. Worn or damaged tensioners or pulleys can cause belt slippage or failure.

Coolant System:

  1. Coolant Level: Check the coolant level regularly when the engine is cold. The coolant reservoir usually has markings indicating the minimum and maximum levels. If the coolant level is low, top it up with a mixture of coolant and water according to the manufacturer's recommendations.
  2. Coolant Quality: Inspect the coolant for signs of contamination or degradation. Coolant should be clear and free of debris. If it appears dirty or has a rusty color, it may need to be flushed and replaced.
  3. Coolant Leaks: Check for signs of coolant leaks under the vehicle or around the radiator, hoses, water pump, and heater core. Leaks can lead to overheating and engine damage. Replace any damaged hoses or components and repair leaks promptly.
  4. Radiator Cap: Inspect the radiator cap for signs of wear or damage. A faulty radiator cap can cause coolant to leak or boil over, leading to overheating. Replace the radiator cap if necessary.
  5. Radiator and Hoses: Periodically inspect the radiator and radiator hoses for signs of corrosion, leaks, or damage. Replace any worn or damaged hoses and have the radiator flushed and cleaned as needed.
