Introduction
Many drivers use the terms coolant and antifreeze interchangeably, but they are not exactly the same. Understanding the difference can help you maintain your car properly.
⸻
What Is Antifreeze?
Antifreeze is a concentrated liquid, usually made from ethylene glycol or propylene glycol.
It is designed to:
- Prevent freezing in cold temperatures
- Raise the boiling point of engine fluids
⸻
What Is Coolant?
Coolant is a mixture of antifreeze and water, typically in a 50/50 ratio.
It helps:
- Regulate engine temperature
- Prevent overheating
- Protect against corrosion
⸻
Key Differences
- Antifreeze = concentrated chemical
- Coolant = ready-to-use mixture
Most modern vehicles use pre-mixed coolant.
⸻
Why It Matters in Miami
Even though Miami doesn’t freeze:
- Coolant is still essential
- Prevents overheating in extreme heat
- Protects engine components
⸻
When to Replace Coolant
