Fit For Ford Fiesta VI Van / VI B-Max-FSM Car Radiator Overflow Water Tank Hose 8V218B081BD 8V21-8B081BD Easy to Install: Direct replacement for old or damaged original coolant expansion tanks, easy to install, no modifications required. High Quality Material: The expansion tank is made of high quality high temperature resistant material, which is more stable in use and has a longer lifespan. It efficiently accommodates the thermal expansion and contraction of coolant, heating up to store the coolant and cooling down to allow it to flow back, maintaining a stable system coolant level throughout the process and preventing engine overheating caused by coolant shortage. Optimized pipe interface curvature ensures a tight fit with the original vehicle's water hoses, eliminating the risk of air intake and leaks, guaranteeing smooth cooling circulation, and extending the lifespan of the radiator and water pump., Manufacturer: ZDGsdgSY
