It’s difficult to see here, but this belt is weathered and cracked. The reason for this is that over time, the
rubber dries out, leaving it brittle and hard. Friction and expansion and contraction from the engine heating
up and cooling down have created the cracks you see here. A belt in this condition is ready to break and leave
you stranded on the side of the roadway. Replace a belt that looks like this.
Hoses: The radiator and heater hoses carry the engine coolant. The coolant is
forced through the hoses under high pressure at high temperatures. This harsh
environment causes deterioration of the hose material, weakening them. Have
the hoses checked regularly throughout the summer and replace any soft or
brittle hoses.
