Niterra, owner of the brands NGK and NTK, List 5 warning signs in the cooling system

Company Highlights Dirt, low level and lack of fluid circulation, as well as abnormal noises in the system and rising temperature in the instrument panel

São Paulo, December 2023 – With the arrival of summer, Niterra, Japanese multinational owner of the NGK and NTK brands and specialized in components for ignition systems and automotive sensors, Highlights five warning signs about the operation of the vehicle's cooling system:

 ;

1- Dirt in the coolant: Known as "radiator water", The coolant is a specific mixture of additive and demineralized water. That is why, The presence of dirt may indicate cooling system problems or fluid contamination, in addition to indicating a degradation of the fluid that hinders heat exchange, Reducing System Efficiency;

2- Low coolant level: A reduced amount of this fluid can point to potential leaks in the system. This is because cooling systems are usually hermetically sealed, And the need for refueling can be a sign of potential leaks;

3- Lack of coolant circulation: This condition suggests water pump problems or clogs and obstructions in the system that can compromise the engine's heat dissipation;

4- Abnormal noises in the system: This irregularity may be related to water pump problems, responsible for fluid circulation or tensioner problems;

5- Temperature rise in the instrument panel: Switching on the warning light may foreshadow a problem and, In this scenario, os sensores de temperatura são cruciais para identificar e alertar sobre um possível superaquecimento.

"These precautions are aimed at ensuring the correct performance of the cars and avoiding problems arising from intense heat", explains Hiromori Mori, Technical Assistance Consultant at Niterra do Brasil. "The cooling system performs the function of keeping the engine temperature stable even in extremely high outdoor conditions."

 ;

According to Mori, parts such as engine temperature sensor (CTS) and intake manifold absolute pressure sensor (MAP) With attached air temperature sensor, they work as allies in the hottest weather situations.

 ;

"These components are responsible for, respectively, Inform the engine management system of the coolant temperature, Activating the electric fan (fan) of the radiator, and make the injection adjustments, and, principally, From the ignition point, Preventing, so, damage to the engine", says Mori. "It is also essential to maintain or inspect the injection and cooling systems."

In this context of extreme heat, drivers can find parts that are essential to the vehicle's performance under the NTK brand, that, in addition to offering the aftermarket high-quality components, such as CTS temperature sensors - responsible for indicating the coolant temperature to the vehicle's instrument panel (Radiator fluid) - and MAP sensors (Manifold Absolute Pressure) – responsible for indicating the absolute pressure of the intake manifold, fundamental for the correct functioning of the injection system, It has fuel level sensors in its portfolio, ABS, rotation, speed, TPS (Butterfly Position) and oxygen.
