Two electric engine coolant pumps are used in conjunction with the belt driven mechanical pump.

The continuously running electric pump mounted on the RH strut tower assists the flow of warm coolant to the heater core at idle when the ambient temperatures are low. A failure in this pump would result in poor heating performance, especially at idle.

The second electrical pump is mounted on the LH of the radiator, which provides the additional flow of coolant through the radiator. This pump is energized when the coolant temperatures reach 90°C (194°F)

The mechanical drive-belt driven engine water pump provides a constant flow of coolant through the engine at all times while the engine is running.
