same topic as was not answered (https://www.pakwheels.com/forums/t/suzuki-swift-over-heat/1066204).
I have same issue.
3 days ago in the evening, after a 1-hour drive, my swift ac tripped. after some time heat gauge up. I turned of car for 2-5 min and filled the coolant reservoir with water.
and restarted the car as well. after 10 min same thing happened and a pipe was broken. I refilled water and waited for 20 min.
The next day the radiator was washed and pipe was fixed.
the local mechanic said the car has still some heat.
I went 80 km far to check. no gauge up but the water was evaporating in the coolant reservoir. I didn't check the radiator.
called a specialist and he said to remove the thermostat, check the water pump, and use high-qualityhe coolant in this weather.
he said that a blown gasket can not be driven outback 100 km.
well, no milky cap, no white smoke, and no water in oil yet.
but in my city temp is usually 40+ (khairpur) and I have to Islamabad in this week.
please need to advise
