Cooling System

Cooling System Articles

Your car's cooling system keeps the engine from overheating by circulating fluid through passages in the engine block and radiator. When this system fails, your engine temperature climbs fast—and an overheated engine can seize up, warp cylinder heads, or crack the block. You land here because you want to understand how coolant flows, what each component does, and what happens when something breaks down.

These articles answer questions like: How does a thermostat control engine temperature? What's the difference between coolant types, and does it matter which one you use? Why does a water pump fail, and what are the warning signs? What causes a radiator leak, and can you drive with one? Understanding your cooling system helps you catch problems early—before a small leak becomes an engine replacement.
