The electric water pump regulates the coolant flow dictated by the electronic control unit (ECU), First Line reports.

When it comes to forced induction engines, additional cooling of the turbo/supercharger after the engine is shutdown is required in order to prevent premature wear, particularly to the turbo bearing.

When switched off, the temperature of the turbo bearing on these engines can reach up to 340°C within seconds, which can result in the oil in the bearing housing losing its viscosity and lubricating properties, causing the bearing to wear and subsequently lead to the failure of the rubber or plastic seals.

Therefore, when the engine is switched off, the electric pump is designed to continue circulating coolant for a number of minutes.

This continues until the turbo has sufficiently cooled, which manages the temperature and prolongs the lifespan of the turbo.

In addition to supplying the replacement component, First Line can advise technicians on how to carry out a successful electric water pump replacement.
