I was bored today and the weather was fairly warm at -10c so I decided to check things over and was checking all the coolant hoses , none are bulging or soft and no leaks any where that I could see including the expansion tank. also since I got the x5 never had to top up coolant. .for the a/c belt no cracks at all, but the alternator belt has some cracks but no chunks out of it so I`ll probally change both anyways in the spring.
