i am new to this forum and my water temp issue is slightly different than others that i have read here. my car runs great with its temp gauge reading around 195 deg.. on cooler days, and at higher vehicle speeds it can drop down to around 165 deg.. however, when my car is idling in traffic or at stoplights the temperature needle starts to climb. once i take off again, the temperature slowly goes back to normal. at this point i can only idle for only a couple of minutes before the gauge reads 225+ degrees. because the car cools down when the engine revs above 2500 rpm i am inclined to believe that it is not the water pump, but i may be wrong. both of the radiator fans are working. coolant level is full. the car is turbocharged and the turbo does generate quite a bit of heat, however the oil temperature gauge does not fluctuate(the turbo is close to the oil cooler) so i am also inclined to rule out extra heat from the turbo. any solutions from someone who has experienced similar problems would be greatly appreciated!!
