Reference 15701-0L030 identifies the oil cooler cover sub-assembly in the selected Hilux offer. The supply is the pictured cover and filter-housing assembly, without a gasket. It should not be assumed to mean an entire oil-cooling circuit or every part associated with the filter.
For this selection, the 1KD engine code is not enough. Keep the restricted build period and supplier configuration with the physical housing comparison.
Keep the early KUN configuration attached to the enquiry
The selected KUN16/KUN26 oil-cover assembly is listed for the Australian 3.0L 1KD-FTV diesel application, 02/2005–08/2006, with the supplier’s non-watercooled-EGR configuration.
That configuration is part of the selection record; it is not an instruction to alter emissions equipment. Other build periods and EGR configurations need a separate fitment check. A registration year or a 1KD description should not remove those limits.
Compare the filter face and engine-side layout
Match the original reference, oil-filter mounting face, coolant connections and mounting-hole layout. Use a complete view to orient the housing before comparing individual connections or bolt positions.
A similar casting outline does not establish every passage, interface or included internal component. Ask for clarification of anything not shown in the package or photographs rather than assuming a complete cooler assembly from a cover reference.
Plan the excluded gasket separately
The supplied assembly has no gasket. Have the installer identify the correct sealing and service requirements, and confirm which surrounding parts remain with the vehicle. A package description should not substitute for diagnosis or the vehicle-specific fitting procedure.
This guide identifies the oil-cover assembly boundary. It does not diagnose an EGR, oil-pressure or coolant complaint, or recommend changes to the vehicle’s configuration.
Send a configuration-aware comparison
Provide the VIN, actual build month, chassis and engine details, original reference and accessible photographs of the complete housing, filter face, hose connections and mounting side. Include the existing configuration with the enquiry and resolve any mismatch before ordering.
