Coolant hose & oil pump connecting flange
This coolant hose is engineered to replicate the original Porsche part’s fit, material and function for the cooling system of Porsche 911 (996 & 997 series). It connects the engine to the supply pipe, ensuring proper coolant flow and stable engine temperatures under all conditions. One end fit the coolant tube the other end fits to the oil pump connecting flange 99710621600

Fits:
Porsche 996 C2 / C4 / C4S 2002 - 2005
Porsche 997.1 C2 / C4 2005 - 2008
Porsche 997.1 C2S / C4S 2005 - 2008

• Location: Cooling system hose, generally the engine to supply/coolant pipe connection.
• Replacement: for factory numbers 997 106 831 03 and cross-references 996 106 831 01, 997 106 831 02.
• Function:  This hose conducts coolant between the engine block and the external supply pipe (or radiator / heat exchanger) as part of the cooling circuit. Correct hose quality and routing are critical to maintaining engine temperature regulation, preventing overheating and avoiding coolant leaks.

Over time, coolant hoses can become hardened, cracked, swollen or leak due to heat cycles, pressure changes and age. A compromised hose may lead to coolant loss, engine overheating, or reduced cooling efficiency.

Replace this hose when:
•  The original shows signs of cracks, bulging, oil or coolant staining.
•  You notice coolant loss, overheating warnings or low coolant levels.
•  You are performing a cooling system overhaul or replacing related pipes/fittings.

Installing this  hose restores reliable coolant flow, proper fitment and long-term durability.
