Custom Metal Coolant Expansion Tanks for Automotive Cooling Systems
This coolant overflow recovery tank is specifically designed for automotive cooling systems to provide overflow protection and fluid recovery under fluctuating pressure conditions, while also facilitating routine coolant top-off maintenance. The front of the product features a large knurled filling cap with a built-in O-ring seal, enhancing sealing reliability and operational stability during the filling process. Hose/fluid connectors are located on the side for overflow inlet and return connections, creating a controlled flow path for the coolant as system pressure fluctuates. This integrated design enables unified management of pressure relief, fluid compensation, and maintenance refilling.

FAQ
Q1: What is the purpose of the knurled cap in the structural design of large-size knurled filling caps?
A1: The knurled texture increases friction during manual operation, making filling and opening more stable, while the built-in O-ring ensures the filling port remains sealed.
Q2: How is secondary contamination or air entrapment prevented after coolant overflows into the reservoir?
A2: The sealed reservoir chamber minimizes contact with outside air, thereby reducing the risk of air entrapment and contamination.
Q3: Does this design affect the radiator's original pressure setting?
A3: No. The overflow reservoir serves solely as an auxiliary storage and buffer unit and does not alter the radiator cap's original opening pressure setting.
Q4: Do the side fittings support flexible installation orientations in different system layouts?
A4: Yes, they do. The routing of the tubing can be adjusted according to the vehicle or equipment layout to accommodate different installation orientations.
