For sale, a 2015 Ddsan radiator fan, seems to be original, red color

For sale, a 2015 Ddsan radiator fan, seems to be original, but I'm not sure. Regarding performance, it worked due to belt tension and heat; the mechanic told me to replace the fan, I replaced it but didn't benefit at all, then I replaced the radiator but still didn't benefit. I have the radiator, if someone doesn't want it, it's available, but I prefer that it be checked at a radiator specialist shop. I also changed the upper hose, it's Chinese.
