What is a Toyota Radiator Tank?

The radiator tank is a crucial component of your vehicle's cooling system. Typically constructed from high-strength plastic or aluminium, it forms the sealed outer shell that holds the coolant and connects to the core of the radiator. The radiator core is where the actual heat exchange happens, but the tank is essential for directing the flow of coolant into and out of the core via its inlet and outlet ports. It also features connections for the overflow hose and often includes the mounting points that secure the entire radiator assembly to your vehicle. In short, the radiator tank is the durable housing that contains and manages the pressurised, hot coolant vital for regulating your engine's temperature.

When Should You Replace a Radiator Tank?

Over time, radiator tanks can succumb to heat cycles, pressure, and age. It's important to consider inspection or replacement if you notice any of the following signs:

  • Visible Cracks or Damage: Hairline cracks, often near the hose connections or seams, are a common failure point.
  • Coolant Leaks: Puddles of brightly coloured (often red, pink, or green) coolant under the front of your vehicle are a primary indicator of a leak from the tank or its seals.
  • Overheating Engine: A compromised tank can lead to a loss of coolant and a drop in system pressure, resulting in engine overheating.
  • Discoloration or Bulging: A tank that appears warped, swollen, or has become brittle and discoloured (often a brownish shade) from excessive heat is at high risk of failing.
