Your car’s cooling system<\/strong><\/a> is a key element that greatly affects the efficiency of our vehicle. It is made up of different components and uses coolant for a number of purposes: The main purpose is transferring heat and <\/span>preventing engine damage <\/b>caused by freezing or boiling. <\/b>The second purpose is for\u00a0<\/span>climate control<\/a><\/strong>\u00a0in the vehicle\u2019s cab during cold ambient temperatures.<\/span><\/p>\n

It plays an essential role for <\/span>keeping the engine within operating temperatures<\/b>, as well as protecting the block thanks to the auxiliary water pump<\/span>, which\u00a0circulates coolant<\/strong> throughout the engine and cooling system.<\/span><\/p>\n

While most vehicles only have a single water pump<\/a><\/strong>, some others have a second water pump that will expedite the process, known by the name of <\/span>auxiliary electric water pump.<\/b><\/a><\/p>\n

But, what is auxiliary water pump<\/a>? These pumps were first used on diesel vehicles and their initial purpose was to cool the vehicle passenger compartment<\/strong>. And now,<\/span> auxiliary water pumps<\/strong><\/a> are fitted to many modern vehicles, typically located at the rear of the engine.<\/span><\/p>\n

So let\u2019s get started. This article provides you with all the necessary details you need to know about this <\/span>type of automotive water pumps<\/span><\/a>.<\/span><\/p>\n

 <\/p>\n

What does the auxiliary electric water pump do?<\/b><\/h2>\n

 <\/p>\n

As its name indicates, its main function is to support the vehicle’s cooling system<\/strong>, although its use is largely intended for the comfort of the passenger compartment. It also<\/span> regulates and distribute the temperature with which the heater is turned on. Regardless of what the thermostat is doing, its main function is to circulate coolant through the engine itself when it is cold.<\/strong><\/span><\/p>\n

This water pump is based on the integration of a hydraulic system, an electric motor and also an on-board electronic module. <\/span>What\u2019s more<\/span>, <\/span>noted for being silent and high durable<\/b>. And also, like the <\/span>electric water pumps<\/span><\/a>, these do not continuously operate.<\/strong>\u00a0<\/span><\/p>\n

Additionally,<\/span> more auxiliary water pumps can be added to the vehicle. This will depend on the complexity of the cooling system that the vehicle has.<\/span><\/p>\n

Thanks to the electrification of vehicles, the auxiliary electric water pumps have led to other utilities such as <\/span>the cooling of batteries<\/b> in Hybrid and Electric cars, a current trend in the market.<\/span><\/p>\n

Differences between a primary water pump and an auxiliary water pump<\/b><\/h2>\n

 <\/p>\n

An auxiliary water pump differs from the primary water pump of the vehicle in a number of different ways. First of all,<\/span> it is an electrically controlled motor<\/b>, rather than the vast majority of water pumps that get its power from a <\/span>timing belts<\/span><\/a> or accessories. It also provides coolant through the heater core when the engine is not running<\/strong> or the RPM is low.<\/strong><\/span><\/p>\n

The auxiliary water pump is not in continuous operation. The BCM (controlling module) <\/strong>will control and regulate the water pump<\/strong> depending on the information obtained. This information is based on:<\/span><\/p>\n
