5. Frequently Asked Questions (FAQ)
Q1: Why do the two uploaded reference images look completely different?
A: The first image shows only a sub-component hose (part number 1303011XKW09A) sold separately. The second image represents the complete, ready-to-install 1303500XKW09A total assembly which includes all required connected lines.
Q2: Does this engine air-bleed assembly include the necessary replacement seals?
A: Yes, the complete assembly shown in Image 2 comes pre-fitted with its vital connection ports, rubber branch hose, and intermediate sealing ring to guarantee leakproof operation out of the box.
Q3: What are the main failure signs of a broken water tunnel overflow line?
A: Persistent micro-leaks or crusty coolant residue around the hard-to-soft transitions, unexpected low coolant warnings, or tiny cracks forming on the rigid sections indicate it is time to replace the whole assembly.
