In the case of the mechanical fan, a thermally sensitive clutch engages when the warm air being pulled through the radiator heats it up. This drives the big fan and pulls a lot of airflow through the radiator.

What causes a car’s radiator to stop cooling?

When a radiator plugs internally these tubes become clogged due to lack of maintenance ( radiator flush) calcium will then stop the coolant flow which inhibits the radiator’s cooling ability. This condition generally occurs gradually over time and will be more noticeable when climbing a grade or in warmer weather.
