OEX Denso Alternator 12V 150A Water Cooled New DXA570WC-79

The OEX DXA570WC-79 is a new 12V alternator rated at 150A, supplied as a fully sealed, water cooled and brushless unit. It uses an internal regulator, a pad mount, and a 9 groove pulley with a 63mm outside diameter, making the key electrical and mounting details easy to match before purchase.

This alternator is listed with a 79 series LandCruiser application only. It is not suitable for 200 series LandCruiser applications, so the part number and vehicle application need to be checked carefully before ordering. The unit weighs 8kg and is supplied as each.

For buyers replacing a Denso-style alternator in an approved 79 series LandCruiser application, the important identifiers here are the OEX brand, part number DXA570WC-79, 12V system voltage, and 150A power rating. The mounting dimensions include 161mm centre to centre, 64mm inside mounting legs, and an IR115 pin code.

Application and Buying Notes

When comparing this alternator to the unit being replaced, check the part number DXA570WC-79 first, then confirm the vehicle is a 79 series LandCruiser application. The note supplied with the product is specific: it will not suit 200 series LandCruiser applications, so model series confirmation matters just as much as voltage and output.

The important physical checks are the pad mount layout, 161mm centre to centre mounting dimension, 64mm inside mounting legs, 63mm pulley outside diameter, and 9 groove pulley section. These are the main points that need to line up with the existing alternator and belt system before the part should be considered suitable.

Electrically, this is a 12V, 150A alternator with an internal regulator and IR115 pin code. That makes it important to match the charging system requirements and connector style, rather than relying on appearance alone. The fully sealed, water cooled and brushless design are relevant construction details, but they do not replace fitment checking.

The unit is sold new and carries a 3 year passenger / 1 year commercial warranty. Warranty terms are useful, but they do not override the need to confirm application, mounting and connector details. For commercial use in particular, it is worth verifying the expected duty cycle and the vehicle application before purchase.

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 DXA570WC-79 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.
