About the Radiator Filler Cap black outline icon
A rectangular radiator core is drawn with seven evenly spaced vertical fin slots, a rounded pressure cap rising on a short neck at the top left and a square outlet tank protruding from the right side. The combination of cap and outlet marks it as an engine cooling unit rather than a room heater. Use it in auto repair booking apps, vehicle diagnostic dashboards, parts catalogs, garage service menus, and maintenance checklists.
Proportions are wide and low, with rounded outer corners and straight capsule-shaped fins that hold their gaps at small sizes. The offset cap breaks the silhouette so it stays recognizable in a dense parts grid. Pair it with engine, oil can and thermometer icons; render at 32 px or above to keep the fin slots distinct.
This is the black outline version of the radiator filler cap icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
