Hi guys, so a little about my car. I have a Mehran VXR 2006 model Fuel/CNG. When I purchased the car it was perfectly fine in terms of drive and smooth run etc. Its been a year now and Im facing problems with the car heating up at around 5 km. Before when i just purchased the car the heating needle would start moving after about 5 to 6km but now after 1.5km the needle starts moving and by 5km it is almost less than half. I got the water body changed, changed engine oil, filter, radiator serviced. The problem is still the same. The radiator water is even fine it doesnt get less, no leakage etc. There is no smoke etc after the needle comes to half even but the car gets hot from inside. I drove it max for around 10km and needle reached half but no smoke etc just that the car geta hot inside. What more can I do?? Need serious technical advice.
