What Problems Occur With Thermostatic Valve Malfunction?

The engine of a vehicle is composed of several mechanisms working in an interconnected way to generate power and ensure good performance and fuel economy.

First of all, it is essential to emphasize that several of the symptoms of malfunctions in the vehicle’s refrigeration system may be related to other circuit defects. These include liquid leakage from the hoses, electro-ventilator malfunction, and sub-optimal coolant.

Therefore, it is necessary to check these items’ conservation state before evaluating the thermostatic valve just Blackhawk supply for instance. In the case of this part, there are some common problems during the vehicle usage time. Check out the main issues now!


Overheating is one of the most feared problems among drivers. In the case of a thermostatic valve defect, it is caused by the shutting of the closed valve. This situation causes the coolant to circulate only through the engine, blocking the connection of the radiator circuit. With this, the engine gradually increases the temperature until it reaches the point of overheating. This problem can lead to serious damage, such as casting parts.

Increased Fuel Consumption

Increased fuel consumption can also be linked to a valve malfunction. This is because when this part locks open or when it is removed from the vehicle, the coolant ends up being supercooled, causing the engine to work at temperatures below the ideal range. This situation generates a greater need for fuel to generate burning in the combustion chamber.

More Friction And Wear Of Parts

The problem of overcooling can compromise the engine’s lubrication efficiency. That’s because engineers design the internal parts to work in certain temperature ranges, with a specific level of expansion for better efficiency.

If the engine runs much of the time at lower temperatures, more space will be between the metal parts. This will make lubrication difficult, causing increased friction between the parts and, consequently, wear.

How To Avoid These Problems?

To be on the safe side, never fail to carry out preventive maintenance, such as changing the coolant and inspecting for leaks. Carry out good driving practices, avoiding, for example, riding in high gears on hills or carrying excessive loads. As already mentioned, never use your vehicle without the thermostatic valve and quick repair when there is a defect in the part. This will contribute to the perfect functioning of the whole set.

This is the main information you should know about the thermostatic valve. Remember that careful and scheduled maintenance practices are always the best way to ensure the extended life of your entire system.
