Hey guys, just noticed a rattling sound coming from a pulley under the engine and popped the hood to have a look and noticed some coolant has been leaking. It's coming from the top hose and dripping down (maybe this is the cause of the pulley noise?). Anyways here's some photos, I'm not familiar with how the hoses on a Benz are but they seem a little more complicated than just getting a hose from AutoZone and slapping it on. Could somebody have a look at my images and give me you're opinion on what I should do? Much appreciated!

Hose is failed, and looks like it failed at the crimp and not the o-ring. Doesn’t matter, it’s an easy replacement. Pull the metal locking tab and replace. No I wouldn’t get a generic hose.

Sweet, I appreciate the reply. 1 question though - could I get away with just popping off the hose and trying to catch any coolant that comes out (obviously on a cold motor) or do I have to completely drain and refill?

With the hose like that I would suggest a coolant change anyway, not real good mixing coolants as some coolants react to other types of coolant and can cause problems later down the track with corrosion of the aluminium.
