I would change the belt, but not the tensioner, on the proviso that it spins smoothly and quietly.

I've just done this on my own 1800, as low mileage does not always equate to being fit for service, and 12 1/2 years is well overdue on time.

The belt part number is 5497XS and with tensioner and water pump is KP15497XS

The original Rover number is LHN100560 and were Gates HTD belts, not Dayco which I won't fit.

Unfortunately there is often no visible indicators that a belt is at the end of service life until it is too late, but at least in the case of the 1800 75 and ZT, they are a complete doddle to replace

P.S. the car in question has covered 15000 miles since fitting seven years ago, so low mileage
