I've not done a coolant change on my 960, but I would second Bill's recommendation regarding taking your time.and definitely change the thermostat (only one type will fit at about $12). I do think changing the hoses and the radiator is a bit severe in my book, unless there is evidence to do so. I would change hoses without question in a car that has 100K+ on it, but then only upon close inspection of the currrent hose condition. I generally favor preventive maintenance, bt I don't think a 5 year old car should need new hoses summarily, let alone a new radiator!
