What's Inside the Manual
This 2,392-page factory reference manual delivers the exact technical data required to maintain and evaluate the Ridgeline. The opening sections lay out general vehicle specifications, chassis and paint codes, and VIN locations. From there, it breaks down the engine's mechanical assembly—including the cylinder head, engine block, and lubrication system—alongside cooling and fuel/emission control requirements. You will also find detailed overviews of the automatic transmission and A/T differential, complete with fluid capacities, gear ratios, and clutch pressure specifications.
System Specs and Diagnostics
The electrical and chassis sections map out the charging and starting systems, cruise control circuits, brakes (including VSA), suspension, and HVAC components. To ensure accuracy during teardowns or inspections, the guide provides extensive standard and service limit tables across all major subsystems. For example, intake valve clearance for the 3.5L V6 is specified at 0.20–0.24 mm, the complete cooling system overhaul capacity is 8.1 liters, and engine oil pressure should read 490 kPa at 3,000 rpm.
Please keep in mind that this data is intended for reference purposes. Always follow standard shop safety protocols or consult a certified technician before undertaking heavy diagnostic work or servicing this equipment.
