AISIN Engine Water Pump WPT-106 — Fits Chevrolet Prizm, Pontiac Vibe, Toyota; Gasket & Bolts, Carbon‑Ceramic Seal

AISIN WPT-106 is a brand-new, OEM-grade engine water pump kit that includes gasket and bolts and fits select Chevrolet Prizm, Pontiac Vibe and several Toyota models.

This replacement water pump is engineered by AISIN, a leading original equipment manufacturer, and is built from all-new components with upgraded materials to resist rust, corrosion and coolant scaling. The WPT-106 uses precision rotors, quality ball bearings and a carbon-ceramic mechanical seal to maintain smooth coolant flow and long service life. Included in the kit are the correct gasket and mounting bolts to simplify installation—confirm vehicle and engine fitment using the fit checker before purchase.

How does this water pump improve my vehicle’s cooling system?

The WPT-106 restores proper coolant circulation through a precisely cast housing and efficient impeller design, helping the cooling system reach and maintain optimal temperatures. High-grade bearings and a carbon-ceramic seal reduce internal wear and leakage risk, supporting consistent performance over time.

• Engineered impeller for steady coolant flow and reduced cavitation
• Durable ball bearings for smoother operation and longer life
• Carbon-ceramic mechanical seal minimizes leaks and contamination
• Materials selected to resist rust, corrosion and scaling

Will this part fit my car and what’s included in the kit?

The AISIN WPT-106 fits specific model years of Chevrolet, Pontiac and Toyota vehicles—fitment can vary by engine, so verify compatibility for your VIN or engine code. The kit ships complete with the water pump, a matched gasket and the mounting bolts you’ll need for installation.

• Compatible models listed: Chevrolet Prizm (1998–2002), Pontiac Vibe (2003–2008)
• Toyota: Celica (2000–2005), Corolla (1998–2008), Matrix (2003–2008), MR2 Spyder (2000–2005)
• All-new, not remanufactured components included
• Gasket and bolts provided to streamline replacement

How reliable is AISIN’s manufacturing and what materials are used?

AISIN has decades of OEM experience and uses upgraded materials chosen to withstand the most common failure modes for water pumps. The construction emphasizes corrosion resistance, scaled-reduction surfaces and robust internal components to maintain reliable cooling performance.

• High-quality metals and coatings resist corrosion and coolant deposits
• Precision-machined housing and impeller for consistent flow
• Carbon-ceramic seal offers superior wear resistance compared with standard seals
• Manufactured as new parts rather than remanufactured units

What should I expect during installation and maintenance?

Installation follows typical water pump replacement procedures and is simplified by the included gasket and bolts; torque specs and belt alignment still must follow the vehicle service manual. Routine checks of coolant quality and proper belt tension will help the new pump reach its designed service life.

• Use proper torque values and replace accessory belts if worn
• Flush or renew coolant as recommended for clean operation
• Inspect hoses and thermostat while replacing the pump
• Confirm leak-free operation after initial run-in

Who is this for: The AISIN WPT-106 kit is aimed at DIY mechanics, professional technicians and vehicle owners seeking a reliable, OE-quality water pump replacement for compatible Chevrolet, Pontiac and Toyota models. Choose this pump when you want factory-level engineering, corrosion-resistant materials and a complete kit (gasket and bolts) to reduce installation time and risk of repeat service. Always verify fitment for your engine variant before ordering.
