Why Is My Car Losing Coolant? Causes and Solutions

“My coolant is disappearing faster than my gas!” exclaimed Tuan Anh, owner of a Thaco Trường Hải truck operating between Hanoi and Lang Son, as he pulled into Minh Phat Auto Repair on Nguyen Van Linh Street in Long Bien District. Coolant loss in vehicles is a common problem, but not everyone understands the causes and solutions. This article provides a detailed overview of this issue.

Why Is My Car Losing Coolant?

Coolant plays a vital role in maintaining the engine’s operating temperature. Coolant loss can indicate various underlying problems, ranging from simple to complex. Here are some common causes:

1. Leaks in the Cooling System

This is the most common cause and can be due to:

• Cracked or Damaged Hoses: Caused by impact, aging, or poor hose quality.
• Blown Head Gasket: A worn or cracked head gasket due to high temperatures allows coolant to leak into the combustion chamber or externally.
• Radiator Leaks: Punctures or cracks in the radiator due to collisions or insect nests.
• Faulty Radiator Cap: A malfunctioning radiator cap fails to maintain pressure, causing the coolant to boil and overflow.

2. Water Pump Failure

The water pump circulates coolant throughout the system. Malfunctions like a damaged impeller or a broken shaft disrupt coolant circulation, leading to overheating and coolant loss.

3. Cooling Fan Malfunction

The cooling fan helps cool the radiator, dissipating heat from the coolant. Issues like a faulty motor, damaged blades, or a malfunctioning control unit hinder efficient radiator cooling, causing the coolant to overheat and evaporate more rapidly.

4. Other Causes

Besides the primary causes mentioned above, coolant loss can also be attributed to factors like:

• Using low-quality coolant.
• Improper driving habits.
• Prolonged operation in hot weather conditions.

• Don’t Add Coolant Without Diagnosing the Cause: Adding coolant without knowing the root cause might mask warning signs of severe damage.
• Choose a Reputable Repair Shop: Select a trusted and experienced auto repair shop like Thai Phong Auto in Cau Giay, Hanoi, to ensure quality service and replacement parts.
