saturday morning i noticed the temp. gauge was reading the car was running a little hot. i did not drive the car again until saturday night when the gauge was reading right to the max. the a/c was not on and the temperature outside was cool. both fans were running so fast i could hear them from inside the car. i was only a couple of blocks from home, so i turned on the heat and headed back. the engine was not pinging and did not feel all that hot when i parked in the garage. i am hoping it is only the thermostat, but i can see from doing a search of the problems fourm, that it may be the water pump. i flushed the system last summer and the car only has 75000 easy kilometre's on it. does this sound like a pump?
