Mine is not heating up even with AC on & in traffic JAM definately their shuold be some technical problem in cars getting heated.
As aleardy disscused in aother post normal running temprature of Uno is about 90~100C so the temp gauge normaly goes above from center but car didnt reduce water from radiator. I had very detailed disscusion with previuos owner actual he was the third owner & I am the fourth in case of my car.
The 2nd owner get fited radiator of some haevy engine might be of Toyota Hiace or small Mazda Truck but that was giving more trouble. When the third owner got that car he decide to keep it stock so he went to mechanic & got back original radiator of his own car after paying 13000/-Rupees. Bullshit....
