Eid Mubarak. I was traveling on motorway, my veh was on CNG. (had turned AC off so that engine shouldnt heat up). However, i was in my thoughts that i started listening to some whistling sound. i kept on ignoring it for i dont know how long. when all of a sudden heat-guage caught my sight. the needle was trying to move past the maximum mark. i stopped car only to find out that even my coolant in the radiator was boiling. i shifted to patrol and completed my journey in stops. It was getting heated on patrol too but not to the full gauge.
that was plot. here is the question. What are the consequences of that much heat (when the gauge shows full reading. Secondly, What is the first thing i should be doing or getting checked by my mechanic? Has my Engine done forever or is there any chance?
Thank for patient.
