The 1J0 121 087D coolant hose flange by URO Parts is an OE-style replacement fitting used on select Volkswagen models equipped with 2.0L and 1.9 TDI 4-cylinder engines. This tee-style connector serves as a junction in the engine cooling circuit, providing a secure interface between the exhaust gas cooler and heat exchanger hose to maintain proper coolant flow and stable operating temperatures. Manufactured under ISO 9000 quality standards, this URO fitting matches OE connector dimensions for a guaranteed direct-fit installation.
Plastic coolant connectors are exposed to constant heat cycles and pressurized coolant flow. Over time, the housing can become brittle, crack, or weaken at the hose barbs — leading to coolant seepage, low-coolant warnings, and potential overheating. Replacing the failing connector with this URO 1J0 121 087D fitting restores a tight, leak-free connection and reliable cooling system performance.
A failing coolant hose flange produces recognizable early warnings. Look for coolant seeping or dried residue around the connector and attached hose ends, a persistent coolant smell from the engine bay after driving, or unexplained drops in the coolant reservoir level. A low-coolant warning light may follow. In advanced cases, a cracked or split housing can cause sudden coolant loss and rapid engine overheating. Physical inspection may reveal a visibly brittle, warped, or cracked plastic body. Prompt replacement prevents further coolant loss and protects the engine from heat damage.

Helps prevent coolant loss and engine overheating
Replace hose clamps if worn and inspect hose ends for swelling or internal cracking before reinstalling. Replacing aging hoses at the same time helps prevent repeat leaks. After installation, refill with VW/Audi-approved coolant and properly bleed the cooling system to remove trapped air before returning the vehicle to service.
Always verify fitment by VIN before ordering.
