I think the car has thermostat installed but I will get it checked. Well during city drive these days the temperature with AC stays close to 90 degrees and as I said in a earlier comment it gets hot on long drive i.e over 110 degrees but only on drive of 100 kms or above. It stays around 103-105 even on inclines. I did a climb of miandam i.e 6500 ft above sea level and the temperature did not cross 105 degrees.
The point is that I have had this car for 3 years and have driven it in extremest of summer temperature but no problem until this may I notice that it is starting to loose water. I had plain water until that point and believe me I did not decrease in during those 2.5 years. I changed from water to caltex coolant 50/50 in mid may and went to swat in mid june where all of a sudden this temperature rise comes that temperature exceed 113 degrees with a drive of 90km/hr with AC on With Ac off the temperature remained near 107-105 but on salt range the temperatures touched 119 and upon stopping the car for 5 minutes with Hood open the temperature was back to 95 degrees. Thats why I think that its radiator is not a culprit.
Another thing what is the white foamy liquid that forms after every 2-3 minutes its like some poured surf in radiator but its not that because I am the only driver of this car.
