Why the Coolant Reservoir Matters

The coolant reservoir provides space for coolant expansion and recovery as engine temperature changes.

A cracked, damaged, or leaking reservoir can contribute to:

• Coolant loss
• Air entering the cooling system
• Reduced coolant reserve
• Cooling-system leaks
• Increased risk of overheating if coolant loss continues
  

Replacing the complete assembly can also simplify service when the existing reservoir, sensor, or caps require attention.
