What This Product Does
This short hose forms the radiator's lower return connection within the coolant circuit. It carries returning coolant through the radiator-section pipework; it is distinct from the longer supply hoses shown in the assembly diagrams.
Functions
- Provides a passage for returning coolant.
- Connects the radiator return section to adjoining coolant pipework.
- Accommodates movement at the hose connection.
Technical Details
- Component: short coolant radiator bottom return hose.
- Left-hand reference: 99110662502.
- Right-hand reference: 99110662602.
- Brand: OE Match.
- Diagram positions vary by application; match the reference to the required side.
Symptoms of Fault
- Coolant pooling beneath the front or collecting on the undertray.
- Damp connections, staining or dried deposits around hose ends.
- A sweet odour accompanied by falling coolant level.
- Cracked, swollen or softened hose sections.
- Low-coolant warnings, gurgling or increased engine temperature.
Why Replacement Matters
Renewing a deteriorated or leaking return hose addresses coolant loss at that connection. Inspect adjoining fittings, seals and retaining hardware during the repair, since an unresolved connection fault can cause further seepage. OE Match's Porsche-focused replacement programme uses application and original-reference checks to identify suitable components.
FAQs
How do I select the correct side?
Match the original reference and diagram position: 99110662502 identifies the left hose; 99110662602 identifies the right hose.
Does front-end coolant leakage confirm hose failure?
No. Inspect the radiator and neighbouring joints too; a cooling-system pressure test can help locate the source.
Why might a leak appear intermittently?
Seepage can become apparent only as coolant temperature and system pressure increase.
