Coolant, also known as antifreeze, is a liquid mixture vital for engine health. It regulates engine temperature, preventing overheating and freezing.

Components Of Coolant

To better grasp what makes coolant effective, let’s break down its key components:

• Ethylene glycol or propylene glycol: Primary ingredient; lowers the freezing point and raises the boiling point.
• Water: Mixed with glycol; helps in heat transfer.
• Additives: Prevent corrosion and scale buildup in the engine.

Importance Of Coolant

Keeping your engine at the right temperature is crucial. Coolant plays several roles in engine performance:

• Temperature regulation: Maintains optimal engine temperature.
• Corrosion prevention: Protects engine parts from rust and corrosion.
• Lubrication: Ensures smooth operation of the engine’s moving parts.

Types Of Coolant

Different engines require different types of coolant. Here’s a brief overview of the most common types:

• Inorganic Acid Technology (IAT): Used in older vehicles; usually green.
• Organic Acid Technology (OAT): Suitable for modern engines; typically orange or yellow.
• Hybrid Organic Acid Technology (HOAT): A mix of IAT and OAT; often found in European cars.

How Coolant Works

Coolant circulates through the engine, absorbing and dissipating heat. This process involves several steps:

• Heat absorption: Coolant absorbs heat from the engine.
• Heat dissipation: Transfers heat to the radiator.
• Cycle repetition: Continues circulating to maintain temperature.

Signs Of Low Coolant

It’s essential to know when your coolant is running low. Watch out for these signs:

• Overheating: Engine temperature gauge rises.
• Coolant leaks: Puddles under the car.
• Sweet smell: Indicates a leak in the system.

Understanding coolant helps ensure your engine runs efficiently and lasts longer. Keep an eye on your coolant levels and choose the right type for your vehicle.

How Does Engine Coolant Work?

Engine coolant regulates engine temperature by circulating through the engine and radiator. It absorbs heat, preventing overheating and ensuring efficient performance. Coolant also protects against corrosion and lubricates the water pump.
