Why Do Large Vehicles Need to Add Water?
2 Answers
Adding water to large vehicles helps in cooling the engine. Below is an introduction to the engine cooling system: 1. Introduction: The function of the automobile cooling system is to dissipate part of the heat absorbed by heated components in a timely manner, ensuring the engine operates at the most suitable temperature. The engine cooling system can be divided into air cooling and water cooling. A cooling system that uses air as the cooling medium is called an air-cooled system, while one that uses coolant as the cooling medium is called a water-cooled system. 2. Cooling System Circulation: (1) Main Circulation: The main circulation includes two working cycles, namely the "cold engine cycle" and the "normal cycle". (2) Heating Circulation: The coolant passes through the heating device inside the vehicle, transferring the heat from the coolant into the vehicle, and then returns to the engine.
I drove trucks for over a decade and fully understand the importance of adding coolant. During long-haul transportation, engines run for extended periods under heavy loads, making them prone to overheating without proper coolant. In summer's high temperatures, coolant absorbs heat to prevent engine damage—insufficient levels can cause water temperature to spike, leading to breakdowns or serious malfunctions. Winter is no different; skipping coolant risks freezing and expansion that damages radiator pipes. Large truck engines have massive displacement and poor heat dissipation, making regular coolant top-ups routine. I always checked fluid levels before every trip to ensure safety. Moreover, coolant doesn’t just prevent boiling and freezing—it also combats corrosion, extending component lifespan. Neglecting this leads to terrifyingly high repair costs. Safety first, never cut corners.
