⚙️ Key Features

• 5.023 kg

• 57 applications across AQ, TD, TWD, TMD, BB and TID series engines

🔌 Function

Holds the coolant that the engine displaces as it heats, keeping the closed circuit full and pressurised.

⚠️ Common Signs of Failure

• Coolant level dropping with a stain or crust down the outside of the tank
• Tank corroded through, cracked or seeping at a seam
• Coolant pushed out of the filler under load
• Overheating with air in the circuit
• Cap seat or filler neck corroded so it will not hold pressure

🛠️ Service Notes

• Check and renew the pressure cap and its seal when the tank is replaced - a cap that will not hold pressure boils the coolant
• Flush the circuit and bleed it thoroughly after fitting, then recheck the level warm and cold
• This is a bulky item to handle - support it while the mountings are undone
