How Often Should You Change Your Car Coolant?

Coolant plays a crucial role in keeping your engine at the right temperature, preventing overheating, and protecting against rust or scale buildup. But many car owners in Pakistan are unsure how often they should change their coolant. Replacing coolant at the right time can save you from costly repairs and ensure smooth performance.

 

Why Coolant Replacement Matters

  • PREVENTS OVERHEATING – Old coolant loses effectiveness and may cause your engine to overheat.
  • STOPS CORROSION – Fresh coolant prevents rust and chemical buildup inside the radiator.
  • EXTENDS ENGINE LIFE – Regular changes protect metal and aluminum components.

 

How Often Should You Change Coolant?

Most modern vehicles require a coolant change EVERY 2 TO 5 YEARS or EVERY 40,000 TO 100,000 KM, depending on the type of coolant used:

  • GREEN COOLANT (IAT Technology) – Typically lasts 2 years or 40,000 km.
  • RED COOLANT (OAT Technology) – Longer-lasting, up to 5 years or 150,000 km.
  • BLUE COOLANT (HOAT Technology) – Balanced performance, usually 4 to 5 years or 150,000 km.

Always check your vehicle’s manual for the manufacturer’s recommended interval.

 

Signs Your Coolant Needs Changing

  • Engine temperature rising faster than normal
  • Rust-colored or dirty coolant in the reservoir
  • Sweet smell from the engine bay (coolant leak)
  • Frequent need to top up coolant levels

 

How to Change Coolant (Step by Step)

  1. Let engine cool completely before opening radiator cap.
  2. Drain old coolant into a safe container.
  3. Flush the system with radiator flush for best results.
  4. Fill with new coolant (use the correct color/variant).
  5. Run the engine with heater on high for 10 minutes.
  6. Top up if needed and close cap tightly.
