Aluminum Radiator Coolant Overflow Tank

The male to barb fitting thread size is M14*1.5 and is compatible with 3/8" ID fuel hose. The overflow tank has a storage volume of 1 liter. This universal coolant reservoir tank fits most vehicles. Please measure before purchasing to ensure proper installation space. The tight closed cap, fully TIG welded construction, and included O-ring gasket ensure a secure seal and prevent coolant leakage. Using Teflon tape during installation is highly recommended to enhance airtightness and prevent interface leakage. When the radiator's coolant pressure exceeds the pressure cap setting, coolant flows through the overflow tube into the reservoir tank. The bottom port serves as the radiator overflow, while the top port is for tank overflow.
