1999 1.1 engine whines and noises - Niamhg

i have just had the water pump and timing belt changed in the Peugeot 206. The garage it was at said they know there was a problem because they counld hear a groaning noise from the water pump. Now I have it back, and the engine is still making noises, both what sounds like a groaning noise to me and a higher pitched noise. The garage says this is the fan belt adjusting as they had to remove it and that it should go away in time. Should the engine not sound a lot better anyway?
