Radiator
In Turkish: Radyatör
In short
A radiator is the heat exchanger in liquid-cooled engines that transfers heat from the hot coolant to the air.
The cooling system consists of the radiator, water pump, thermostat, fan and fan switch, and the radiator cap. The thermostat keeps the radiator circuit closed until the engine is warm; the fan switches on as temperature rises.
- Coolant (antifreeze) is usually changed every 2–3 years; it protects against freezing and corrosion.
- Signs of overheating: a rising gauge, a fan that does not run, boiling in the overflow tank.
- Bent or clogged fins reduce cooling; clean them with a soft brush and low-pressure water.
