Engine Cooling

Most, small aircraft are air cooled by the air intakes in the front of the cowling. Where others are liquid cooled.

On air-cooled airplanes, the outside airflow enters the large openings, baffles route and circulate the air over fin's attached to the cylinders and around the exterior of the cylinders and engine, before exiting out of the bottom through the cowl flaps.

Avoid operating an engine at higher than normal temperatures, this can cause a loss of power, oil consumption and will also lead to permanent damage such as scoring of the cylinder walls, damage to pistons and rings and burning of and warping the valves.
