A coolant flange or cooling system T-joint is a connector within the engine cooling circuit designed to distribute coolant flow between different hoses. It ensures leak-free connection and stable coolant circulation.
The component may be manufactured from heat-resistant plastic or metal. Depending on vehicle design, it may include mounting points for temperature sensors, sealing rings, or quick-connect fittings.
Failure symptoms include coolant leaks, antifreeze odor, dropping coolant level, or engine overheating.
Our catalog includes coolant flanges and T-connectors for many vehicle brands. Genuine cooling system components, reliable aftermarket replacements, and tested used units without cracks or deformation are available.
Used parts are inspected for housing integrity, sealing surface condition, absence of micro-cracks, and fitting wear.
Selection is based on VIN number, engine type, hose diameter, and part number. Replacing a damaged coolant flange restores system sealing and proper engine temperature control.
