Mazda 5 Reservoir Tank for Sale

Experiencing coolant leaks, discoloration, or overheating in your Mazda 5? The coolant reservoir tank is often the overlooked culprit. This OEM-Mazda 5 Reservoir Tank is designed for 2006–2015 Mazda 5 models and restores essential cooling system function by maintaining proper coolant expansion and recovery.

Built from tough, heat-resistant materials, it’s a direct-fit part—no cutting or custom brackets needed. Whether your original tank is brittle, cracked, or leaking, this unit gets your Mazda 5 back to a safe and efficient operating temperature.

Mazda 5 Reservoir Tank

The Mazda 5 Reservoir Tank allows for coolant expansion when the engine heats up and returns it to the radiator when it cools down. If the tank is cracked or warped, it can lead to coolant loss and overheating. Replacing it with a properly molded, pressure-rated tank prevents system failure, protects engine components, and ensures efficient thermal cycling.

Benefits

  • Prevents overheating by stabilizing coolant volume
  • Maintains pressure balance for improved engine efficiency
  • Reduces coolant leaks and evaporation
  • Protects engine components from heat-related damage
  • Restores factory-level performance and reliability
  • OEM-style fit means fast, hassle-free installation

Features

  • High-density polyethylene (HDPE) construction
  • Semi-transparent body for quick fluid checks
  • Molded sensor port (plugged if not used)
  • Screw-on fill neck compatible with OEM caps
  • Pre-molded mounting tabs for direct factory fit
  • Chemical-resistant and UV-stabilized plastic
  • Compatible with factory hoses and fittings
  • Designed for consistent coolant expansion and recovery

Performance

Your cooling system relies on pressure stability and controlled coolant cycling—especially during extended drives or in stop-and-go traffic. This reservoir tank withstands daily thermal stress, resists cracking, and prevents air from entering the system. It ensures that your radiator and water pump can do their jobs without interruption, helping to maintain engine temperature within safe limits.
