Application and Buying Notes

Before ordering, compare the part number DXS4001, the 12V rating, 9 tooth pinion and clockwise rotation against the starter being removed. On starter motors, matching the mounting pattern and dimensions is just as important as matching the electrical specification, so check the 122mm mount centres A, 74mm flange diameter and 2 hole mount layout carefully.

The listed Denso style and suits unit make of Denso indicate the type of application this unit is intended for, but the exact match still depends on the vehicle and the starter fitted from factory. The fitment information supplied includes Lexus LS, Toyota Corolla, Toyota Noah/Voxy and Toyota RAV4 applications, but those should still be confirmed against the vehicle details and the original part.

If you are replacing a unit that has suffered wear, poor cranking or heat damage, it is worth checking the pinion at rest measurement of 14mm and the 29mm pinion diameter against the old starter. Those physical checks can help avoid delays and reduce the risk of fitting a part that looks close but does not line up correctly.

The 1.6kW power rating and 2.92kg weight are useful reference points when comparing starter assemblies. They do not replace fitment checking, but they can help confirm that the replacement is broadly in the same category as the original unit before installation begins.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number DXS4001 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

OEX Starter Motor 12V 9Th CW Denso Style. Part number DXS4001 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number DXS4001, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include LEXUS LS, LEXUS LS 2006, LEXUS LS 2007, LEXUS LS 2008, TOYOTA COROLLA, TOYOTA COROLLA 2006. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using part number DXS4001, the Denso style application, and the measured mounting and pinion details before purchase or installation. Vehicle fitment can vary by build date, engine application and original equipment fitted, so the original starter remains the best reference point.
