What This Product Does
The replacement pipework carries coolant through the radiator-section supply and return circuits. It addresses deteriorated connections and crossover pipes where corrosion or seepage has developed.
Functions
- Conveys coolant through the front cooling circuit.
- Connects supply and return pipework.
- Replaces affected pipes and hoses during cooling-system repairs.
Technical Details
- Supply cross tube reference: 99710671103; return cross tube reference: 99710672003.
- Connecting hose reference: 99710672307; diagram quantity: 2.
- Distributor tube references: 99710675104 and 99710675204. Supply and return descriptions vary between the supplied application diagrams.
- Left-side hose references: 99710662303 and 99710672803; right-side hose references: 99710662703 and 99710662403.
- Sleeve reference: 99710655103; diagram quantity: 2.
- Supplied 997.1 Carrera diagram identifies M96.05 3.6L and M97.01 3.8L Coupé/Cabriolet applications, 2005–08.
Symptoms of Fault
- Coolant collecting beneath the front of the vehicle.
- Damp connectors, staining or dried coolant deposits.
- A sweet odour accompanied by falling coolant levels.
- Low-coolant warnings, gurgling or increasing temperature readings.
Why Replacement Matters
Corrosion and ageing joints can allow coolant to escape. Renewing affected pipework addresses the leak source; adjoining hoses, seals, clips and supports should also be inspected rather than assuming the pipes alone explain every cooling fault.
FAQs
How can the leak source be confirmed?
A cooling-system pressure test can help distinguish leaking pipe joints from radiator or other cooling-component faults.
Does the kit provide every installation consumable?
Check the component contents against the planned repair. Do not assume coolant, additional seals, clips or mounting hardware are included.
Is gurgling proof of a failed pipe?
No. Low coolant or trapped air can produce similar sounds, so diagnosis is needed before replacing components.

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.

What This Product Does
This hose carries coolant along the radiator supply connection. It forms part of the circuit linking the radiator with the vehicle’s cooling pipework; it is the long feed version, rather than the short return hose.
Functions
- Provides a passage for coolant at the radiator feed connection.
- Connects the relevant radiator inlet to the adjoining coolant pipework.
- Accommodates movement at the flexible connection.
Technical Details
- Brand: OE Match.
- Configuration: long radiator supply hose, top connection.
- Left version reference: 99110662102.
- Right version reference: 99110662202.
- Diagram positions vary by application; match the reference and side rather than relying on the item number alone.
Symptoms of Fault
- Coolant collecting beneath the vehicle’s front end.
- Moisture or dried deposits at hose connections.
- A falling coolant level or dashboard level alert.
- A sweet odour near the radiator pipework.
- Cracks, bulging or unusually soft hose sections.
- Higher temperature readings or escaping steam.
Why Replacement Matters
A leaking or deteriorated feed hose can allow coolant to escape. Renewing a confirmed faulty hose addresses that source of fluid loss. Check adjacent fittings, clips and sealing surfaces during the repair, since damage elsewhere can cause leakage to recur. OE Match develops replacement components around Porsche applications, with reference matching and fitment assessment forming part of its product evaluation.
FAQs
How can I distinguish a hose leak from a radiator leak?
Inspect the hose ends alongside the radiator joints and end tanks. A cooling-system pressure test can help locate the source.
Why does leakage sometimes appear only after a journey?
A marginal connection may seep only while the cooling circuit is hot and pressurised.
Should the retaining hardware also be checked?
Yes. Inspect clips, clamps and adjoining fittings, replacing damaged or unsuitable components as required.
