Do AIO Coolers Come Pre-Filled or Do I Need to Fill Them?

Hey folks! I've built quite a few PCs with tower air coolers, but I've never used an AIO cooler before. I just got a Be Quiet Light Loop 240mm AIO, and it came with a bottle of liquid, but the manual is pretty terrible and doesn't clarify if I need to fill the radiator myself. I'd hate to have to disassemble it, so what's the deal? Do these typically come pre-filled or what?

Most AIO coolers come pre-filled, so you usually donโ€™t need to worry about filling them yourself. If you gently shake the radiator and hear sloshing, thatโ€™s a good sign that itโ€™s filled! I've personally never dealt with one that required user filling.

CoolBuilder42: Thanks! Iโ€™ll try shaking it to see if I hear anything. Itโ€™s just odd since they gave me that bottle labeled 'water and propylene glycol'. It makes me wonder if mine can actually be refilled or if itโ€™s just a misunderstanding on my part.
