Any hole in the coolant system will eliminate the ability for the system to hold pressure. Unpressurized coolant boils off at far lower temperatures than pressurized. Your car WILL overheat under these conditions. My engine DID overheat under these conditions... one time only (bad filler cap and loose pipe plug on filler nech due to previous owner's incompetence). I replaced my engine due to bad O-rings 5 months later.
You MUST replace the coolant hoses to the engine. There are 14 of them, and if one is gone, the rest are going. I don't know how hard it is for you to get those hoses in the Middle East, but you really need to do this, or you will be looking for a replacement engine in the Middle East.
I mean it.
