- Check radiator condition, get it cleaned or replaced if required. Use recommended quantity coolant.
- Make the radiator fan direct (short thermostat terminals).
- Your LPG kit maybe set for richer mix of lpg, get it set properly.
If still it heats then it will be a good idea to run it on petrol while you are using AC and later switch to LPG when car gets cooled or when not using AC at all. |
