“A stitch in time saves nine,” especially for trucks, the lifeblood of countless families. Besides regular maintenance at reputable garages like XE TẢI HÀ NỘI, every driver should know how to care for their vehicle. Today, let’s explore a seemingly simple yet crucial task: adding coolant to your truck.

1. Coolant: Its Vital Role and Essential Knowledge

1.1. Why is Coolant Important?

Coolant, also known as engine coolant or antifreeze, plays a crucial role in maintaining the stable operation of a truck’s engine, especially for those carrying heavy loads and traveling long distances. Without sufficient coolant, the engine can overheat, leading to severe damage, even stalling, affecting work and income.

Mr. Nguyen Van A, an auto repair expert at Thanh Cong Auto Garage, Cau Giay District, Hanoi, stated: “Many cases of severe truck damage are due to owner negligence in checking and adding coolant regularly. This seemingly simple task significantly impacts engine longevity.”

1.2. Common Coolant Types

Currently, there are two main types of coolant on the market: pre-mixed coolant and concentrated coolant.

• Pre-mixed Coolant: Convenient, ready to use after purchase.
• Concentrated Coolant: Requires mixing with water at a specific ratio, usually 1:1 or as directed by the manufacturer.

Choosing the right coolant type depends on individual needs and budget.
