What does auxiliary water pump do?
The function of an auxiliary water pump Its primary use is circulating water by way of a bypass hose from the main coolant lines to a heater core. The heater core is used to collect heat and distribute warm air into your vehicle when the heater is turned on.
Which is a symptom of a bad auxiliary water pump?
Since it is the primary job of an auxiliary water pump to supply hot coolant to the heater core, it seems obvious that the first symptom of a problem with this component would be no hot air blowing from the heater. The auxiliary water pump moves hot water or coolant that has recently circulated through the engine block to the heater core.
How does an auxiliary water pump work in a car?
Heater has fluctuating heat. The auxiliary water pump is a consistent flowing device that circulates warm coolant into the heater core – regardless of how fast your engine is running. Because of this fact, if you set a temperature on the thermostat control (if your car has one), it should remain solid.
Where is the auxiliary water pump on a hot water heater?
The auxiliary water pump is typically located at the rear of your engine, where the main water line splits to supply the heater core with recently heated coolant. On rare occasions, the auxiliary water pump will experience an electrical problem where the pump runs faster than it should or will continue to run after you’ve turned the engine off.
What can cause a water pump to overheat?
A clog in the suction line or strainer may be restricting the flow of water and can cause cavitation or loss of prime. Either of these conditions can cause the pump end to overheat. 5. The Motor is Drawing too Much Current

What are the symptoms of a bad auxiliary water pump?
1. No warm air is coming from the heater Since it is the primary job of an auxiliary water pump to supply hot coolant to the heater core, it seems obvious that the first symptom of a problem with this component would be no hot air blowing from the heater.
What happens when the water pump fails in a car?
When the water pump fails or is beginning to wear out, it can lead to complete engine failure. When the water cooled (as opposed to air cooled) engine was introduced, many automotive experts believed that the water pump circulating coolant through the engine block was just as critical to engine protection as oil.
Is the auxiliary water pump connected to the heater?
On the test drive, the system may perform great for you. The issue could be the auxiliary water pump. This pump is not connected to the cooling of the engine. Its primary function is to circulate warm coolant to the heater core.
