@pwuser171497134013 Charade AC is as good as of modern cars may be even better, less maintanance. Anyone saying Charade cannot have a good air conditioning he is a joker.
- First you need to make sure that car engine is not weak especially the head.
- Car cooling system is working as it should with atleast radiator fan auto on/off, quality coolant with proper working radiator cap.
- Obviously with proper AC setup including healthy modern compressors (duet or Terios can be good options).
Normally people do not focus on points 1 n 2 and blame the car. Because even AC is properly tuned car can become problematic.
Just to support the aurgument,
I have been using G11 since 2009. I am getting 12 km/lit in city and 14 - 15 on the highways.
During heatwaves I travelled to Hyderabad when temperature was around 55 with 5 adults, AC was continously working, travelled around 160 kms @ speed around 90 without any engine heatups or radiator pressues issues.
I hope it helps.
