Inspect Belts and Hoses: Why Rubber Parts Fail in Summer Heat

belts and hoses

When the summer heat sets in, most drivers think about air conditioning and engine cooling—but don’t forget your vehicle’s belts and hoses. These essential rubber parts are especially vulnerable in hot weather, and a failure can leave you stranded. At Bender’s Auto Sales, we’re here to help you stay on the road safely. Here’s what to watch for.

Why Heat is Hard on Rubber

Rubber components like serpentine belts and radiator hoses expand and contract with temperature changes. Over time, heat causes them to dry out, crack, or even separate. Under the hood, temperatures can soar well above 100°C, accelerating wear and tear—especially during summer.

Warning Signs of Trouble

  • Visible cracks or fraying on belts

  • Squealing sounds during startup or turning

  • Bulges, soft spots, or leaks on hoses

  • Overheating engine or sudden coolant loss

What These Parts Do

Belts power vital systems such as the alternator, power steering, and A/C. Hoses transport coolant to and from the radiator. A single failure can impact your entire engine system or lead to an expensive repair.

Regular Inspections Make a Difference

Even if everything looks fine on the surface, age and wear can be hiding beneath. Belts should generally be replaced every 100,000 km or as recommended by your vehicle’s manual. Hoses should be checked at every oil change and replaced if they show any signs of wear.
