Engine Coolant Reservoir Water Expansion Tank T2H19682 car engine radiator cooling pot coolant expansion tank Suitable For Jaguar

Product Description:

Coolant expansion tank

OE number: T2H19682

Applicable vehicle type: For Land Rover

The automotive expansion tank, commonly known as the 'auxiliary water tank', or 'overflow tank', is an essential pressure regulation and buffer container in modern car cooling systems. It typically consists of a semi-transparent plastic reservoir, a cap, and connecting tubing, marked with 'MAX' (maximum) and 'MIN' (minimum) scale lines.

Its core function is to accommodate the volume changes of the coolant due to thermal expansion and contraction, ensuring that the cooling system always operates in an ideal state of full liquid and free of gas.

Core functions and importance:

• Accommodating thermal expansion: When the engine operates, the coolant temperature rises and its volume expands. Excess coolant and generated steam flow into the expansion tank to prevent system overpressure.
• Supplementing coolant: After the engine is turned off and cools down, the coolant volume contracts, creating a vacuum that draws coolant from the expansion tank back into the radiator, maintaining a 'full' state in the system to avoid cavitation.
• Discharging air: Air and steam in the coolant separate in the expansion tank, with air vented through the cap's pressure relief valve, reducing system air resistance and enhancing cooling efficiency.
• Indicating liquid level: The transparent design of the tank allows owners and mechanics to visually check the coolant level.
• Maintaining system pressure: The cap integrates a pressure valve and vacuum valve to keep the cooling system operating at a specific pressure (typically 0.9-1.5 bar), raising the coolant's boiling point.

Common faults:

• Body aging and cracking: Prolonged exposure to high temperatures and pressure causes plastic aging, leading to coolant leakage.
• Lid seal failure: Fatigue of the pressure valve spring or aging of the sealing ring results in abnormal system pressure (low pressure may cause 'boiling over', while high pressure increases leakage risk).
• Internal dirt accumulation: Long-term failure to replace coolant leads to the buildup of scale and impurities, which may block connecting tubes.

Fault symptoms:

• Unexplained reduction in coolant: Presence of pink/green coolant crystals or stains on the body or connectors.
• Engine overheating: Due to insufficient coolant or air entering the system.
• Abnormal cooling system pressure: After lid failure, coolant may overflow from the lid, or cooling tubes may collapse.
• Dashboard water temperature warning light illuminates.
