I just went to a mechanic to book a full service on my car, driving off from the mechanic reved the engine to about 4000 and bam, Ive got a big round circular piece of metal fly off, managed to pick it up off the road, and two belts that are bust.
What do the two belts do? (Luckily cambelt is still on there

)
Ive realised that they have to be for Aircon, Power Steering, and alternator, is there anythign else the two belts do?
Mind you it seems to go alot faster now. (still get the tick tick tick noise

)
Also theres some liquid leaking out now

Im not sure if its oil or what

Gonna let some more leak out and have another look.
