When to Replace a Timing Belt, Serpentine Belt, Coolant Hoses
Losing a belt or hose today can mean big trouble for the engine tomorrow. Serpentine belts are used on most engines to turn the water pump, alternator, power steering, and air-conditioning compressor. Timing Belts are used to drive major internal components such as the crankshaft and camshaft and can cause catastrophic engine damage when they fail. If a belt snaps, you may be stranded. A blown hose could result in an overheated engine and can cause additional engine damage.
“It’s not easy to know the true condition of a belt or hose by its outward appearance, because most belts and hoses fail from the inside out,” said Rich White, executive director, Car Care Council, an automotive consumer education group. “Replace belts, radiator and heater hoses at specific recommended intervals to prevent your car from breaking down.”
- Hoses should be checked at each oil change for age hardening (or softening) by pinching. Any hose that feels rock-hard or mushy is due for replacement. Leaking, visible cracks, blistering or any other visible damage on the outside of the hose also indicates a need for replacement.
- The clamps should be replaced when new hoses are installed.
- Special tools are available to professional Technicians to measure the deterioration of drive belts.
- Drive Belts and especially, timing belts may turn a tan color as they age and the rubber becomes less pliable and hardened.
- On old timing belts will show clearly defined indentations of the timing gear teeth on the back side of the belt.
- Drive Belts should be replaced every three to four years or 40,000 to 50,000 miles.
- V-belts and serpentine belts should be checked for looseness and cracking.
- Replace the timing belt between 60,000/5 years and 90,000 miles / 7 years or based on the interval specified in the owner’s manual.
Nearly one-third of all cars and light trucks currently being driven on the road have belts or hoses that should probably be replaced. Proper maintenance of your vehicle’s belts and hoses is an easy way to protect your car’s reliability and prevent more costly repairs down the line.
