Expansion Tank Caps
The expansion tank cap is a critical component of the engine cooling system, designed to regulate pressure and protect the system from coolant loss. By maintaining the correct operating pressure, the cap helps increase coolant boiling point, improve cooling efficiency and support stable engine temperatures under all driving conditions.
Although small and often overlooked, a faulty expansion tank cap can lead to coolant leaks, overheating and reduced cooling system performance. Manufactured to rigorous quality standards and engineered for dependable sealing performance, Serck expansion tank caps provide reliable pressure control and long-term durability across a wide range of passenger car and light commercial vehicle applications.
Expansion tank caps are among the most frequently replaced cooling system components. Exposure to constant pressure changes, heat cycles and coolant vapours can gradually weaken seals and springs, affecting their ability to maintain correct system pressure.
StockASSIST helps identify the expansion tank cap applications most commonly required by UK workshops, ensuring factors can stock the products technicians need most.
