🔌 Function

Holds the coolant expansion volume and gives a visible level check for the cooling system.

⚠️ Common Signs of Failure

• Coolant level dropping with no leak found elsewhere
• Tank cracked, crazed or weeping at a seam or spigot
• Coolant staining or crusting down the outside of the tank
• Tank collapsing or ballooning as the system heats and cools
• Overheating because the system cannot hold its coolant

🛠️ Service Notes

• Check the cap, hoses and mounting straps while the tank is off - they age with the tank
• Refill and bleed the system properly, then recheck the level once hot and cold again
• Never open a hot cooling system - wait until it has cooled before working on the tank
