OEM Water Pump O-Ring for 2001-2004 Nissan Pathfinder models equipped with the VQ35DE powertrain. 

The Water Pump O-Ring is a small rubber or silicone ring that forms a seal between the water pump and the engine block. It is responsible for preventing coolant leaks and maintaining the proper pressure within the cooling system. Over time, the O-ring can become worn, brittle, or damaged, which can lead to coolant leaks and engine overheating.

Here are some signs that the water pump O-ring may need to be replaced:

• Coolant leaks: If you notice coolant pooling underneath your vehicle or dripping from the front of the engine, it could indicate a faulty O-ring. Coolant leaks can lead to engine overheating and potential damage if not addressed promptly.
• Engine overheating: A failed O-ring can result in coolant leakage, leading to inadequate cooling of the engine. If your engine temperature rises consistently or you receive a warning light indicating overheating, it is important to inspect the water pump O-ring as a potential cause.
• Visible damage or wear: Inspect the O-ring for signs of cracking, crumbling, or deterioration. Over time, the rubber or silicone material can degrade due to heat, age, or exposure to coolant and other chemicals. If the O-ring appears damaged or worn, it is advisable to replace it.
• Routine maintenance: The water pump O-ring is often replaced during regular maintenance when the water pump itself is being serviced or replaced. It is a good practice to replace the O-ring as a preventive measure to avoid potential leaks in the future.
