Understanding the impact of cold temperatures on car engine coolants Coolant analysis is often overlooked by industries in their preventive maintenance. While coolants keep engines running smoothly and are formulated to function effectively in extreme temperatures, it is essential to be informed about their impact. Let’s understand this impact and take a deep dive into the steps involved in ensuring the coolant’s effectiveness and the measures that are essential to mitigating any negative effects. Effect of cold temperatures on coolant: Proper freeze protection is needed when it's cold Freezing can result in cracking and damage to the engine block and/or cooler, allowing coolant and lubricant to mix, and when it does, further damage to the asset will occur, leading to a costly, unpredictable repair. Cold temperatures weaken the coolant's protection against corrosion and cavitation. In frigid conditions, a poorly formulated or maintained coolant may become too...
