Information
Water radiator top hose, Intake (Upper Left).
OE Match upper-left radiator coolant hose (intake/top hose) designed to replicate the factory hose routing and connections on Tiptronic-equipped 996 and 986 models.
Fits:
Porsche 996 C2 / C4 1998 - 2005 TIPTRONIC
Porsche 986 Boxster 2.5L / 2.7L 1997 - 2004 TIPTRONIC
Porsche 986 Boxster S 3.2L 2000 – 2004
This product supersedes Porsche's old part numbers:
- 99610666555
- 99610666557
Diagram Ref No 8.
This hose transports coolant through the upper (intake) side of the left radiator circuit, supporting efficient heat rejection and stable engine operating temperature.
Function: This hose links the radiator coolant plumbing on the upper-left side and is shaped to maintain correct flow while clearing bodywork, brackets, and neighbouring hoses. Correct fitment is important to prevent restriction, rubbing, and leak paths at the hose ends as the system expands and contracts with temperature.
Cooling hoses are wear items. A weakened upper hose can split or leak under pressure, leading to coolant loss and overheating risk. Replacing with an OE Match hose restores secure sealing and correct routing, helping protect the engine and keep the cooling system operating as intended.
When to replace:
• Visible coolant seepage at hose ends or along the hose body
• Hose feels overly soft, swollen, brittle, or cracked
• Coolant smell/steam from the front of the car
• Cooling system refresh (radiators/thermostat/water pump service)
• Preventatively on higher-mileage 996/986 models
