Detailed Product Information
URO part number 4284303 is an HVAC heater hose made for the Saab 900 heater circuit connection from the water pipe to the heater by-pass valve. The molded EPDM construction helps maintain the original hose path, which is important for fitment, clearance, and a factory-style layout in the engine bay. If you are replacing a worn Saab 900 heater hose, 4284303 provides the correct shape and connection sizes for the listed applications.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Common Repair Uses
- Replacing a cracked or softened heater hose on a Saab 900
- Restoring coolant flow between the water pipe and heater by-pass valve
- Correcting leaks caused by age, heat cycling, or ozone exposure
- Addressing hose collapse, swelling, or poor routing in the heater circuit
Installation Notes
Verify the hose routing and connection points before installation. This molded hose is shaped for the OE path, so alignment with the water pipe and heater by-pass valve should be checked during removal of the original part. Confirm the end diameters and molded profile match the vehicle before final assembly.
