Need Advise: HOT (overheating) F650

[rvatorflash]

Hi,

Am in Erdek, Turkey and am having a problem with my bike overheating. Went for a ride yesterday and the bike began overheating every few kilometers. Coolant level in resevoir looks normal. Radiator fan appears to be inoperative but I lost the fan before and had no problem with overheating as long as I was not in stop-and-go city traffic or climbing a big hill on a hot day. Therefore, the fan may have been inoperatıve for some time without me noticing... I think the problem is the water pump but would like to be sure before trying to get one shipped from İstanbul (or Germany??). My question: How do İ determıne if the pump has failed? Maybe disconnect the hose from the water pump to the back of the cylinder cooling jacket, start the bike and see if coolant gets pumped out? Not sure this will work as İ do not know the direction of circulation. Another questıon: Anthing tricky about replacing the water pump? Appears to be held on by 4 Torx-head fasteners. Just remove the fasteners and replace the old pump wıth a new one? Last question: Is there a thermostat in the system? İf so, the problem could be a stuck thermostat whıch İ assume could just be removed??? As a foreigner am unable to register a SIM card for my phone, few people speakıng Englısh here, few bıkers, and have been unable to access my e-maıl account from this ınternet cafe. Would VERY MUCH appreciate any input. Thanks!!!
