I have done the following test...

- Both the fans are running perfectly
- No leakage anywhere

First of all thanks for your valuable response.

Thermostat, I don't know how to test it.

Upper hose is too hot, when the red light blinking in my car.

Sometimes reservoir getting empty, sometimes it is full.

Previously after 10 kilometers, the red light will blink.

But now it has reduced to Just 5 Kilometers itself.

So the problem is getting even worser. Need to fix it at the earliest.

Last time when i did the oil change, mechanic said oil level is very low. So it seems to be its eating the oil also.
