§ Atlas · Interactive Reference

Underbody Explorer

Identify what you're looking at under an Astro or Safari before you touch it. Tap a hotspot to see whether a line carries coolant, fuel, EVAP vapor, or brake fluid — and open the matching Atlas article. This is a v1 schematic placeholder: labeled photos and per-year/drivetrain overlays plug into the same layer model as the Atlas grows.

Safety-critical identification

A wet line near the fuel tank is not automatically a brake line. Confirm the fluid before deciding whether the van is safe to move. See Rear brake line rust near the fuel tank.

Roadmap

Planned layers: front subframe & steering, mid-body fuel/EVAP by year, AWD transfer-case & propshaft, and rear disc-brake conversions. Contribute labeled photos through the Admin Research Console.
