AskPatty's Car Care Tips to Improve Safety and Reliability, Tip #2
Inspect Hoses At Each Oil Change
Have them replaced when leaking, brittle, cracked, rusted, swollen, or restricted. Check V-belts and serpentine belts for looseness and condition, and have them replaced when cracked, frayed, glazed or showing signs of excessive wear. Typically replace the timing belt between 60,000 and 90,000 miles or at the interval specified in the owner's manual to avoid a breakdown or serious engine damage.
