Detailed Product Overview
WAI 19043N is built for Lexus applications that use a Denso PMGR starter configuration, including Lexus IS250, IS350, GS350, GS300, RC300, and RC350 coverage across model years from 2006 through 2018. The permanent magnet gear reduction design supports efficient cranking performance, while the 10-tooth, clockwise-rotation layout matches the specified OE-style starting system requirements. If you are replacing a failing starter on a Lexus IS350 or Lexus RC350, this unit is specified for the listed Denso PMGR fitments.
This part cross-references Carlson 19043 for the same application.
What This Starter Helps Address
- Engine no-crank condition
- Slow or weak cranking during startup
- Intermittent starter engagement
- Starter noise from worn internal components
- Starting issues tied to a failed Denso PMGR unit
Installation Notes and Tips
Verify the vehicle’s starter configuration before installation, including Denso PMGR design, clockwise rotation, 10-tooth count, and flange mounting. Confirm the exact model year and build date where applicable, since some 2018 Lexus applications are listed with production cutoffs such as to 10/2017 or to 11/2017. Match the original starter specifications to the vehicle’s electrical and mounting requirements before replacement.
Quality Assurance
WAI states that this starter is manufactured as a new unit using proprietary components and processes to support service life and performance. The design is intended to meet the amp output demands of today’s vehicles while maintaining OE-style fitment for the listed Lexus applications.
