Coolant Service Video

Coolant, also called antifreeze, carries heat away from your engine and keeps internal temperatures within a safe operating range. It also protects the block, water pump, and heater core from freezing, corrosion, and mineral scale.

This coolant and antifreeze video shows how coolant moves through the system and what it looks like in the reservoir. It also explains how the thermostat opens once the engine warms up, allowing hot coolant to flow through the radiator. In normal operation, the mixture cycles continuously between the radiator and the engine, absorbing heat and releasing it through the radiator fins.

Warning signs usually show up in the driveway or on the temperature gauge. A sweet smell or a puddle of green, orange, or pink fluid under the front of your vehicle can indicate a coolant problem. Other common warning signs include a rising temperature gauge or a low-coolant warning light.

Cape Girardeau winters make proper freeze protection especially important. Over time, coolant’s corrosion inhibitors deplete, leaving aluminum radiators and other cooling-system components vulnerable to corrosion. A Parks Automotive inspection checks fluid condition, tests freeze protection, and pressure-tests the system for hidden leaks.

When the fluid or a component needs attention, schedule a cooling system inspection for the full diagnostic and repair scope. Drivers from Jackson and Scott City bring their vehicles to us for cooling system work.

If your temperature gauge is rising or you notice colored fluid under your car, call Parks Automotive at (573) 335-2599. You can also visit a  car repair shop near me in Cape Girardeau  to have your coolant checked before a small leak leads to engine overheating.
