VW/Audi designed much of their coolant piping from hard plastic, which often becomes brittle after years of exposure to hot coolant and constant heat cycling. Over time, these components commonly crack or break, leading to leaks and cooling system failures.
This coolant flange replacement is manufactured to OE specifications, ensuring perfect fitment and quick installation. Replacing cracked or worn flanges helps restore sealing integrity and keeps your cooling system operating at peak efficiency.
Includes:
Note: O-rings for sensors must be ordered separately (Part # N 903 168 02).
For best results, check all associated hoses, fittings, and clamps when performing the repair, and replace as needed. Pairing the replacement with fresh coolant will ensure a reliable, leak-free cooling system.
JC PRONTEZZA supplies OEM-quality coolant flanges, hoses, and sealing components to protect your engine from overheating.
