Application and Buying Notes

Before you order, check that your vehicle uses a Denso-style alternator and compare the mounting dimensions on your original unit with this part. The key identifiers here are DXA4037, IR115, 12V, 100A, twin leg mount, 65mm inside mounting legs, and 169mm centre-to-centre. Those measurements are the practical checks that matter when matching the replacement.

Pulley detail should be confirmed carefully. This alternator is listed with a 7 groove clutch pulley, 55mm outside diameter, and a note that it will replace a 6 groove clutch pulley original using the 6 grooves closest to the fan. If your original alternator or belt setup differs, do not rely on appearance alone; compare the groove count, pulley offset, and mounting arrangement.

The unit is new and uses an internal regulator, so there is no need to match an external regulator setup on this part. That said, electrical compatibility still depends on the exact application and connector arrangement in the vehicle, so the pin code IR115 and the Denso unit make should be checked with the existing alternator or parts record before purchase.

If you are buying for a Toyota Camry or Toyota RAV4 application, use the model years listed alongside this part as a guide only, then confirm the physical unit on the vehicle. Alternators can vary by build specification, so the safest approach is to match part number, pulley section, mount type, and dimensions rather than relying on the vehicle badge alone.

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 DXA4037 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.

Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include TOYOTA CAMRY, TOYOTA CAMRY 2011, TOYOTA CAMRY 2012, TOYOTA CAMRY 2013. 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.

Compatibility note: Please confirm fitment by matching the part number DXA4037, pin code IR115, Denso unit make, pulley details, and all mounting measurements against the original alternator before ordering.
