NISSAN 21074-2W201 Water Pipe Gasket

The genuine NISSAN 21074-2W201 (Water Pipe Gasket / GASKET-PIPE) is a critical sealing component within the vehicle's cooling system. Its function is to provide a leak-free seal at the connection between the water pipe and the engine block, cylinder head, or thermostat housing, ensuring the sealed and pressurized flow of coolant.

Technical Features and Material Quality:

• High-Quality Base Material: Made from a specialized heat- and coolant-resistant elastomer compound capable of withstanding high operating temperatures and the chemical effects of antifreeze additives.
• Precise OEM Fit: Manufactured to Original Equipment Manufacturer (OEM) specifications, guaranteeing exact dimensional accuracy and distortion-free sealing.
• Long Service Life: Delivers superior resistance to cooling system pressure fluctuations and engine vibrations.

Function and Symptoms of Failure:

Maintaining correct cooling system pressure is vital for keeping the engine at its optimal operating temperature. A damaged or aged water pipe gasket can cause coolant leaks, impairing cooling efficiency and ultimately leading to engine overheating.

Common symptoms of failure include:

• Visible coolant traces or residue around the water pipe joint.
• Continuous drop in coolant level within the expansion tank.
• Sweet odor inside the engine compartment caused by evaporating hot coolant.
• Unwanted increase in engine operating temperature.

To maintain cooling system reliability, replacing the gasket with a new genuine OEM part is always recommended whenever the water pipe is disconnected or coolant pipes are replaced.
