Belts and Hoses

Condition and fittings
Look under the hood and inspect all belts and hoses to make sure there are no signs of bulges, blisters, cracks, or cuts in the rubber. High summer temperatures accelerate the rate at which rubber belts and hoses degrade, so it’s best to replace them now if they show signs of obvious wear. While you’re at it, check all hose connections to make sure they’re secure.
