MTE-THOMSON, recognized as one of the leading manufacturers of engine coolant thermostats in the country, standing out in the automotive aftermarket, and being a brand widely remembered and recommended by repair technicians due to the quality and reliability of its products, demonstrates its expertise in manufacturing items for the cooling system since 1957, explaining some complications of the lack of preventive maintenance.
The engine coolant thermostat is essential for the correct functioning of a vehicle’s cooling system, directly influencing the engine’s ideal temperature. When there is a defect in this component, a series of problems can arise, significantly affecting the vehicle’s performance and safety. Below, we detail five problems caused by defects in the engine coolant thermostat, emphasizing the importance of opting for components from renowned manufacturers such as MTE-THOMSON.
-
Engine Overheating
One of the most common symptoms of a defective engine coolant thermostat is engine overheating. This occurs because the thermostat, when it does not open correctly, prevents the coolant from circulating through the engine, causing the temperature to exceed the ideal value. This overheating can cause serious damage to the engine, such as deformation of components and in the cylinder head.
-
Insufficient Engine Warm-Up
Contrary to the previous problem, a engine coolant thermostat that remains open will cause the engine not to reach its ideal operating temperature, leading to insufficient warm-up. This can result in increased fuel consumption, higher pollutant emissions, less power, efficiency, and premature engine wear, since an engine that operates below the ideal temperature does not function efficiently.
-
Engine Temperature Variation
A defect in the engine coolant thermostat can cause variations in the engine temperature, where the temperature rises and falls irregularly. This usually indicates a thermostat that is not adequately controlling the flow of coolant. These fluctuations can lead to irregular vehicle performance and potentially cause long-term damage to the engine.
-
Change in Fuel Consumption
A defect in the engine coolant thermostat can lead to a significant change in fuel consumption. On the other hand, if the thermostat remains open, the engine may not reach its ideal operating temperature, resulting in a richer fuel mixture to compensate for the lower temperature. This also leads to an increase in fuel consumption, in addition to potentially causing damage to the catalytic converter and the oxygen sensor due to excess unburned fuel.
-
Premature Wear of the Cooling System
Improper functioning of the engine coolant thermostat can lead to a continuous cycle of overheating and cooling, which exerts additional pressure on the cooling system, including the water pump, radiator, expansion tank, and hoses. This premature wear can result in cooling system failures, requiring costly repairs and even the replacement of components.
“Choosing quality components is essential to ensure the proper functioning of the cooling system and, by extension, the vehicle as a whole. MTE-THOMSON offers a portfolio with more than 3,000 items for cooling, electronic injection, and exhaust systems, which meet the needs of repair technicians and vehicle owners, ensuring ideal engine performance and avoiding problems resulting from failures and lack of adequate maintenance,” explains Alfredo Bastos Jr., Marketing Director of the company.
