Quick Scoop

ARC Coolant in ARC Raiders comes from defeating ARC enemies and looting their bodies, with better odds in high-loot red zones and on tougher ARC types. Common farm targets mentioned across guides include Pops, Fireballs, Comets, Surveyors, Sentinels, and bigger machines like the Queen or Matriarch, though the easier roll-style bots are usually the fastest route.

Best Places

The most repeated farming advice is to go into red/high-value loot zones and clear lots of ARC spawns there. Players and guides point to areas like Dam Battlegrounds, the Hydroponic Dome Complex, Research and Administration, Stella Montes, and other high-risk map sections as productive spots for coolant drops.

Fast Farm Targets

If you want the quickest path, focus on the smaller rolling enemies first. Multiple sources say Pops and Fireballs are the easiest enemies to chain-kill while still having a solid chance to drop ARC Coolant, while larger ARCs can also drop it but are slower and riskier to fight.

Practical Route

A simple loop is:

  1. Enter a red-zone area.
  2. Hunt Pops, Fireballs, and similar ARC units.
  3. Loot every defeated ARC, even ones you did not personally down.
  4. Extract as soon as you have enough coolant to avoid losing it.

Extra Notes

Some community posts say Baron Husks and Comets can be especially good depending on the map and event conditions, while storm or probe-related runs may also help. Drop rates are still RNG-based, so the safest strategy is to maximize ARC density rather than chase a single guaranteed spawn.

Bottom Line

If you just want the shortest answer: farm red zones , kill Pops/Fireballs , and loot every ARC body you see. That is the most consistent way people are finding ARC Coolant right now.
