High-Quality Materials: This engine coolant reservoir is made of high-quality, high-temperature resistant plastic, capable of withstanding the high temperatures, pressure changes, and continuous vibrations within the engine compartment. The reinforced structure effectively prevents cracking, deformation, and premature aging, reducing the risk of coolant leakage and ensuring long-term stable use under various driving conditions
Semi-Transparent Design: The semi-transparent outer shell of this coolant reservoir allows for easy viewing of antifreeze and coolant levels without opening the radiator cap. This helps drivers detect abnormal levels promptly, reducing the risk of engine overheating and ensuring safety during daily driving and long-distance travel
Product Function: The coolant expansion tank can store excess coolant that overflows due to temperature rise during engine operation, and return it to the radiator after the engine cools down. This helps maintain the normal circulation of the cooling system, prevents coolant loss, and keeps the engine at a stable temperature
Easy to Use: Manufactured according to OE standards, this product directly replaces original parts 603-253 / 1K0121407A. Its plug-and-play design requires no complex modifications or special tools, saving installation time and costs. For best results, professional installation is recommended
Compatible Vehicles: This engine coolant reservoir is compatible with 2006-2019 Audi A3, Q3, RS3, TT models and 1993-2019 Volkswagen Beetle, CC, Eos, Golf, GTI, Jetta, Passat, Rabbit, Tiguan, etc. Please verify vehicle compatibility before purchasing
