Introduction to Coolants and High Mileage Engines Coolants, also known as antifreeze, play a crucial role in maintaining the optimal operating temperature of an engine. Their primary function is to absorb the heat generated during combustion and facilitate its dissipation, preventing overheating. This is particularly important for high mileage engines, which often experience increased wear and tear. High mileage typically refers to vehicles that have surpassed 75,000 miles, leading to various performance challenges, including the need for stronger, more effective cooling solutions. As engines accumulate miles, their components can degrade in efficiency, leading to overheating and potential engine damage. Thus,…
