Check the ODO Temperature reading. Already 31Degrees. We at middle-east are having toughest summer. The previous year the same ODO (displayed below) read temperatures in the range of 51, 52, and 53 Degrees. Most American and Japan vehicles are designed to withstand high temperatures. What my suggestion is to check the Radiator, and Coolant periodically. The coolant must be specific, and recommended by the manufacturer. This is highly suggested in Indian vehicles.
