Coolant Leak is a mod that allows the Sentinel to freeze and slow all enemies at close proximity in a similar manner to Cold b Cold procs.


  • It has a very small radius of 3 meters.
  • The speed reduction of 10% is relatively low.
  • Unalerted enemies that fall under the effect of this mod will become alerted.
  • Cannot be used for Transmutation, although it will appear in the codex entry.
  • Note that this mod is not passive (unlike Mod TT 20pxSanctuary) and is actively involved in the precepts order.
  • It can be traded, though isolated reports of being unable to trade exist, most likely connected to other factors.


  • In Capture Missions, it is recommended to use this mod's effect to slow down your target, preventing them from running away from you and making it easier to capture them.



  • While dueling in the Dojo, a Sentinel with Coolant Leak installed will affect its owner.
  • If a player that has a Sentinel equipped with Mod TT 20pxCoolant Leak is affected with Radiation b Radiation, the player is slowed. The player will continue to be affected until either the Sentinel or the player dies.
  • Sometimes Coolant Leak cannot be traded, when trying to trade a pop-up message will tell you that unique abilities or copies of it cannot be traded.

    • Havy anyone noticed this mod slowing your warframe? I playing a Rhine Prime that suddenly became a lot slower.
    • If you are procced with radiation, the sentinel sees you as an enemy, therefor slowing you down as you are in range.
