As in the title. Yesterday i was driving around and saw the Temp goes all the way up.. I immediately stopped the car and let it cool down then i top up the water (normally i got collant in there) . After cooling down and topping up the water the car was fine. In the morning i checked the radiator again and water level dropped not much as yesterday but it dropped . I filled up the water and the Reserve drove around and then i checked again and the water level dropped again.. During the drive today once i saw the Temperature went up to 75% almost. Again I parked the car in shade and let it cool down (didn't top up the water ) Started the car and the temp leve was at 50% middle..
I got some one to check it he is saying may be the gasket is gone but how can i make sure ? and where can i get a proper gasket and cost ?
