BLOX Racing coolant expansion tanks are designed to catch coolant overflow and properly re-circulate it back to the radiator. The proper re-circulation ensures that your engine continues to operate at safe temperatures.

BLOX Racing coolant expansion tanks are manufactured using high quality stainless steel. Unlike aluminum, the fully polished body resists corrosion and stains.

BLOX offers 2-different sizes for easy fitment and mounting. Each style includes a pressure cap and mounting hardware.

Expansion tank size specs:

• 2" x 15", 26oz capacity (Longer)
  
• 3" x 10", 34oz capacity (Shorter)
