I have serviced heater core, it was having some debris in it.
So now, heater is working but mild hot air is coming because the Radiator fan is direct (although thermostat is installed) due to gasket replacement. Mechanic says gasket is changed by previous owner, head face is expected not to be in the genuine condition so car can be overheated during your journey.
What do you recommend guys should i make the fan auto?
I was using guard coolant green one, but now mechanic told me to use caltex coolant mixed with AC water.
I am planning a trip from KHI to LHR after 15 days.
