Agreed, this may be a normal condition. But, let me offer another possibility... Some 9000 models, depending on market and options, come with a 2-speed radiator fan. It could be that your "low speed" fan function is not working, so the fan doesn't activate until the engine reaches the higher temperature required to turn on "high speed". If this is the case, the cause could be the temperature switch on the radiator, the resistor that regulates the low fan speed, or one of several relays and fuses. Might want to get your hands on an electrical manual...
