Please compare your original cap number or check via registration before ordering. STOP COOLANT LOSS AND OVERHEATING: A cracked or worn expansion tank cap loses system pressure, causing coolant loss, low-coolant warning lights and the risk of engine overheating. This cap restores the sealed cooling circuit with a rated pressure of 1.45 bar (145 kPa), helping to keep the coolant where it belongs. A low-cost fix that can prevent expensive engine damage. OE-SPECIFICATION REPLACEMENT: Not an original Ford, Mazda, Volvo or Land Rover part, but a replacement manufactured to original specifications. Heat-resistant plastic body, precision pressure valve and a reliable sealing ring for a long service life in the engine bay. EASY FITMENT IN MINUTES – NO TOOLS: Allow the engine to cool completely, remove the old cap by turning it anti-clockwise, check the sealing surface, then screw on the new cap until it clicks into place. Important safety note: never open the cooling system while the engine is hot, as hot coolant under pressure can cause serious burns. WHAT'S IN THE BOX & FIT CHECK: 1 × coolant expansion tank cap (radiator reservoir cap). To verify fitment, read the part number from your original cap (e.g. 1301104 / 3M5H8100AC / LR000243) or send us your registration number (VRN) – we will check compatibility before you buy.
