sounds like the pump is bad. do you notice that the temp is alright when you are at highway speeds,and the temp goes up when you are at slower speeds (<40-45 mph) or at idle?
if your car has 140km on it, i assume you did a timing belt change already. idk what the recommended milage for a timing belt change is for your accord, but my ek was at 90-100,000 miles. anyways, you should change the water pump, thermostat, and maybe the radiator hoses at the same time.
your water pump is on the block, you probably can't see it, it might be behind the lower timing belt cover.
