Hi people. My MV6 BJ 1996 was recently at the “Friendly” for oil and brake fluid changes. On the bill is now among other things: BEFUND: Timing belt change due. Can this be after original 14.500 km ??? Yes, yes. True already BJ 1996 and original 14.500 km. I looked at the belt once exactly. It looks like new. No cracks, no signs of wear, nothing. Is there besides the miserable long belt that drives the alternator among other things maybe still one under a Thank you for your help. Greetings, MV6-Cruiser
