drive belt buying guide
Why replace this part?
Drive belts transmit rotational power from the crankshaft to engine accessories including the alternator, power steering pump, air conditioning compressor, and water pump. On serpentine systems, a single belt drives all accessories; a failure leaves the vehicle without charging, cooling, or power steering simultaneously.
Signs you need a replacement
- Squealing noise, especially on cold start or when loads increase (A/C on)
- visible cracks, missing ribs, or glazing on the belt
- battery warning light
- power steering suddenly heavy
- belt debris visible in the engine bay
When to replace
Every 60,000–80,000 miles or 5 years, whichever comes first. Always replace the tensioner and idler pulleys at the same time — worn pulleys rapidly destroy a new belt.
