Mini Cooper S 1.6 petrol 2001 issues..

[shotbyjoeyultra]

hey guys n gals, just bought a mini cooper s 1.6 2001, passed the MOT, but i had another friend who's an MOT guy and he had a look, said the air con pipe has been cut?, i was like who or why would anybody cut it?, and also the rear drivers side when ever i go over bumps in the road it sounds like i've killed a gerbil.. no idea what that is, but its driving me INSANE. Also i put coolant in the coolant pot and the next day i have to put more in?, from reading on here its something to do with a thermostat or something?, also why is the fan to cool the engine down so LOUD?? if it was a supercharged beast i can understand but a 1.6 sports mini cooper?.. makes no sense.
Any advice would be appreciated as i have never owned a mini before. i bought it for a project, so i plan to renew any old parts that need doing, and give it some new health, its a brilliant car so far, just few issues. any advice would be great, thanks!!

Thanks

Joey
