Checking The Water Pump

Activate the water pump.

There must be a buzzing sound from the water pump when it is activated.

The fault is permanent if the water pump does not start.

If the water pump starts, this is an indication that the fault was present previously but that it is not active at the moment, i. e. the fault is intermittent.

Remedy as necessary.
