Automotive Belts & Hoses

 
What people often learn the hard way is that belts and hoses age, and what happens when they fail.  The coolant leaks out and the engine overheats.  Most belts and hoses fail from the inside out.  The rubber deteriorate with age and exposure to heat.   The material can become hard and brittle.  Tiny cracks develop which eventually cause leaks, blisters or splits.  But what happens if you never replace your belts or hoses?  Hopefully nothing because nobody can predict when a belt or hose will actually fail.  But if a failure does occur, the consequences can often be far more serious and expensive than a breakdown and a tow.  Overheating is the biggest danger.  Depending on how hot an engine gets, the consequences my include a blown head gasket, a cracked or warped cylinder head and/or a broken or frozen overhead camshaft.
