Coolant holder is an item used in Back to the Freezer. It is found in a crate in the storage room of the secret bunker in the past. It should be used with the ice maker in the break room to make a cool-ant.
Unlike most items, it has a separate version in each of the non-English RuneScape translations, with a separate icon in order to continue to have a pun.
