AISIN Engine Water Pump P/N:WPT-808.
The AISIN water pump for your Toyota or Lexus is an OEM-quality replacement designed to meet or exceed factory specifications. As one of the world's leading water pump manufacturers, AISIN produces pumps that deliver exceptional cooling efficiency, durability, and reliability—key factors in ensuring the longevity of your Toyota or Lexus' 3.5L V6 engine (2GR-FKS).
Key Features of the AISIN Water Pump for your Toyota or Lexus
-
Precision Machined for a Perfect Fit
- The AISIN water pump is built using exacting tolerances to ensure it bolts directly into place without modification. This results in OEM-level fitment and eliminates the need for adjustments during installation.
-
High-Quality Materials for Longevity
- AISIN utilizes aluminum die-cast housings, which provide optimal heat dissipation while maintaining a lightweight structure.
- The internal components include stainless-steel bearings and carbon-ceramic seals that resist wear, reducing the risk of premature failure.
-
Efficient Cooling Performance
- The precision-balanced impeller ensures smooth coolant flow through the system, preventing hot spots and reducing stress on the engine.
- Designed to maintain consistent coolant circulation, helping to regulate engine temperature under all driving conditions.
-
OE-Equivalent Sealing
- Comes with high-quality gaskets and seals to prevent coolant leaks, reducing the chances of overheating and costly engine repairs.
-
Corrosion-Resistant Design
- The water pump’s components are coated to resist corrosion, protecting against rust buildup even in extreme temperatures and harsh conditions.
Why Choose an AISIN Water Pump Over Aftermarket Alternatives?
- OEM Supplier: AISIN is a direct supplier to Toyota/Lexus, meaning their water pumps are engineered to the same quality standards as the factory-installed units.
- Longer Service Life: Many aftermarket pumps use inferior bearings and impellers that wear out faster, leading to coolant leaks or impeller failure. AISIN’s factory-tested design ensures long-term reliability.
- Optimal Performance for the 2GR-FKS Engine: This 3.5L V6 has a reputation for durability, but maintaining a healthy cooling system is key. A failing water pump can lead to overheating, warped cylinder heads, or head gasket failure—all costly repairs.
Signs That Your 2GRFKS Needs a New Water Pump
- Coolant Leaks: If you notice puddles of coolant under the engine, it could be a sign of a failing gasket or bearing inside the pump. A failed gasket for this specific water pump may typically appear on the side of the pump facing the firewall.
- Whining or Grinding Noise: Worn-out bearings inside the water pump can produce a whining or grinding sound from the engine bay.
- Steam from the Engine Bay: A failing pump can lead to coolant leaks that cause steam to rise from under the hood.
Installation Considerations
Replacing the AISIN WPT-808 water pump on a 2GRFKS Toyota or Lexus can be labor-intensive due to its placement behind the timing cover. Here are some key installation tips:
- Consider replacing the electric thermostat and coolant at the same time for optimal cooling system longevity.
- Use factory-spec coolant (Toyota/Lexus Pink Super Long Life Coolant) to prevent compatibility issues.
- Inspect the serpentine belt and pulleys while replacing the pump to avoid future maintenance issues.
