Radiator leaks , at the left corner bottom right next to the discharge valve. Consulted some mechanic and was told that the radiator is made of aluminium, can't be repaired and need to replace.

Anyone can offer some help ?

 

Try aking it to another shop.
I was leaking antifreeze as well, and it was only the water pump.
If you have high mileage, if could be time to replace it.
