KUTTOLE Stainless Steel Electric Water Pump Rotor for Toyota Prius/Lexus CT 2010-2016 — Bench-Balanced, Corrosion-Resistant Upgrad

This replacement rotor is precision-machined from corrosion-resistant stainless steel as an upgrade over common ABS rotors, offering improved balance and durability for high-temperature, high-load cooling systems. It is bench-tested before shipping and designed to match OEM fitment numbers so you can replace a damaged rotor and return coolant circulation to specification for many Toyota, Lexus, and select Honda hybrid applications.

How will this rotor help when my hybrid vehicle shows a cooling fault?

A worn, deformed, or cracked pump rotor can restrict coolant flow while the pump housing remains intact. Replacing the rotor can often resolve flow-related errors, engine overheating events, or intermittent cooling faults without the expense of a full pump replacement.

• Restores proper coolant circulation by replacing damaged impeller vanes.
• Prevents escalation to overheating when diagnosed early.
• Bench-balanced to reduce vibration and extend pump life.
• Compatible with common hybrid models—check fitment against OEM numbers.

What models and OEM numbers does this rotor fit?

This rotor is produced to fit a wide range of hybrid vehicles from Toyota, Lexus, and selected Honda models. Always verify compatibility using the listed part numbers and your vehicle's year and engine specification before ordering.

• Common OEM references: 161A0-29015, 161A0-39015, WPT-190, 161A0-290015.
• Toyota applications include Prius (2010–2015), Prius C, Prius V, Prius Plug-In, Camry Hybrid, Avalon Hybrid, Corolla Hybrid, Prius Prime.
• Lexus fitment includes CT200h and ES300h hybrid variants.
• Selected Honda models: Accord, Clarity, CR-V, and Insight hybrid variants—confirm before purchase.

How is this rotor different from other replacement options?

KUTTOLE’s rotor is a one-piece stainless steel design rather than the injection-molded ABS commonly found on aftermarket rotors. The material choice and precision machining improve resistance to high temperatures and mechanical stress typical of hybrid cooling systems.

• One-piece stainless steel construction for corrosion resistance.
• Precision-processed for improved assembly accuracy and dynamic balancing.
• Tested on a bench to validate balance and performance prior to shipping.
• May show light surface marks from testing—these do not affect function.

What should I expect during installation and warranty support?

Installation typically involves removing the pump housing to access the rotor; if the pump body shows no leakage, replacing only the rotor can be a cost-effective repair. KUTTOLE backs this rotor with a 1-year warranty and customer support to help confirm fitment and troubleshoot issues.

• Replace only the rotor when pump housing is intact to save cost and labor.
• Follow manufacturer torque and sealant recommendations during reassembly.
• 1-year warranty and responsive KUTTOLE customer support available.
• Pre-shipment function testing reduces the likelihood of immediate failure.

Who is this for: This stainless steel pump rotor is intended for automotive technicians, DIY mechanics, and fleet owners seeking a durable, OEM-referenced replacement part for hybrid cooling systems. It’s especially useful when coolant flow issues point to a damaged impeller while the pump housing remains serviceable. Confirm your vehicle model year and OEM part number before purchase to ensure correct fitment.
