PROBLEM IS SOLVED
before Eid i go to machanic for head gasket change but he advice me that their is very minor leak in the gasket so it is not necessary to change the gasket at this stage so i decided to not change the gasket and decided to use some good quality coolant in the radiator so i buy 2 bottles of union extended life coolant which is dark blue in color so after 2 to 3 days i see some drops of blue coolant into my gariage. So im sure about it that their is a leak in the cooling system before ,this it is necessary to mention here that before this blue coolant i use CALTAX extended life coolant which is orange in color , and after that i use osaka coolant green in color but i was unabable to find any leak , after seeing the blue drops on the floor i open the bonet and check each and every point but i was unabel to find any leak so i took my car in the sunlight and agin try to find the leak and this time i was lucky i found the leak on the small pipe which is connected between the heater pipe and the CNG kit , the leak is very minor that is why the coolant level in the radiator never drops so i change this pipe with very good quality pipe and now ALHUMDILLAH their is no bubbles in the radiator
I want to slute all the local machanics and all the suzuki authorized dealers who tell me that head gasket is leak and head needs to be service and the expense is 15 K
Thanx to ALLAH who saves me from gasket change because 2 times i go to machanic for gasket change but luckily the machanic is very honest man and he advice me not change the gasket at this stage .
Thanx to all pak wheels members , speciallay XULFIQAR bahai .
I attach the pics of the pipe which have a very minor leak and create the huge problem and the pic of the coolant which iv oil like coolant very good in quality
