The key to summer driving is keeping the engine cool. The hoses connected to the radiator help pump coolant to and from the engine block, and the belts run the fan that helps cool the system further. If the hoses crack or the belts snap, the radiator will quickly overheat, leaving you stranded.
Check hoses for cracks, leaks and loose connections. Hoses should be firm, never soft and malleable. Hoses suffer from a slow deterioration process called electrochemical degradation (ECD) that eats away at rubber hose material from the inside. The most vulnerable parts of the hose are those nearest to clamps where the hose connects to the radiator or the engine.
