Why Do Large Trucks Always Need to Add Water to Their Radiators?
2 Answers
Large trucks frequently need to add water to their radiators because heavy-duty trucks carry substantial loads, resulting in greater inertia. When braking downhill, the friction between the brake shoes and the brake drums generates significant heat, causing the drums to become extremely hot. Prolonged exposure to high temperatures can lead to carbonization of the brake drums, potentially causing brake failure or tire blowouts. Below are some key points about encountering large trucks on the road: 1. Avoid Truck Blind Spots: Trucks have large blind spots, particularly on the right side. During normal driving, trucks often occupy the center of the lane, and if slower vehicles block the fast lane, drivers may attempt to overtake from the truck's right side, significantly increasing the risk of accidents. 2. Hazards of Truck Turns: When a large truck turns, it exhibits a phenomenon known as 'off-tracking,' where there is a difference in the path of the front and rear wheels on the turning side. If a passenger car lingers in this zone, the truck driver may not see it at all. It is crucial to move away quickly.
I've been driving trucks for over a decade, and the radiator constantly needs water mainly because the engine's large size causes temperatures to skyrocket rapidly during operation. Especially during long-haul trips or when hauling heavy loads, the accumulated heat accelerates coolant evaporation. The radiator materials themselves degrade over time, with seals loosening or developing tiny cracks, causing slow leaks. When driving on highways in summer, the temperature gauge rises alarmingly fast. If you forget to add water, the engine might emit white smoke or even burn out components, leading to costly repairs. That's why I've developed the habit of stopping every few hundred kilometers to check water levels, promptly topping up with purified water or coolant to ensure safe and smooth operation. Regular maintenance of the cooling system also helps prevent unexpected failures and reduces the risk of breakdowns.
