The 6 Benefits of coolant flow control valve


Ever wonder why your car’s coolant system is so important? Or what does it, for that matter? Well, let this article be your guide. Here are some of the most common questions about coolant flow control valves:

Protects the engine

One of the most important benefits of a coolant flow control valve is that it will prevent your engine from overheating. Overheating can lead to serious damage and greatly shorten your vehicle’s lifespan, so this is a big deal! If you’re driving on a hot day and feel like something is wrong with your car, check out your coolant flow control valve before doing anything else.

Prevents damage to other parts of the car

Not only does it protect the engine itself, but this type of device also helps keep other parts in good condition by preventing leaks or blockages within them.

Prevents corrosion

  • Prevents corrosion: The coolant flow control valve protects your engine from corrosion, which can cause severe damage to parts of your car’s engine. This includes preventing rust from forming on the engine and preventing corrosion from spreading to other parts of the engine.
  • Protects against overheating: By keeping coolant flowing at all times, this part prevents overheating by regulating how much heat is lost through evaporation. This helps keep temperatures within normal ranges so you can drive safely without worrying about damaging any part of your vehicle’s structure or performance capabilities.

It serves as a filter

A coolant flow control valve serves as a filter for coolant before it enters the engine. It filters out dirt and contaminants that can cause damage to the engine, as well as maintain its life.

Reduces noise

  • Reduces noise by allowing more air to flow through the engine.
  • Reduces noise by reducing the amount of air sucked into the machine.
  • Reduces noise by reducing the amount of air that is pushed out of the engine

Helps maintain a proper air/fuel ratio

The coolant flow control valve helps maintain proper air/fuel ratio by controlling the temperature of the air entering the engine. The valve regulates coolant flow through a small passage in its body, connected to a larger passage leading from your radiator. When you start up your vehicle, cold water enters both sides of this small passage at once and begins flowing through it until it reaches a specific temperature–at which point hot coolant takes over and starts moving through both sides again. This process allows for more accurate control over intake temperatures than would be possible if only one side were used simultaneously (i.e., with no flow control valve).

Reduces the overall cost of ownership

The coolant flow control valve helps to reduce the overall cost of ownership by reducing the need for repairs, extending the life of your car, and reducing maintenance costs.


The coolant flow control valve is important to your vehicle’s cooling system. It helps to protect the engine and reduce noise, as well as other things like corrosion. If your vehicle needs this part replaced or serviced, contact a mechanic at AutoMD today!
