HELLO from Azerbaidjan!!!

Are you sure the fan is engaging ?

The mechanical fan clutch will be fully engaged with the engine temp at 90C, and
probably will have engaged at a lower temp. If it's not engaged by 90C, it's defective. With the car in park and temp at 90C or higher, pop the hood/bonet, and rev the engine slowly. The fan should roar loudly up to ~3500rpm, you can hear it disengage by 4000rpm, then let the revs drop slowly and the fan should re-engage by ~3000rpm. If yours doesn't do this, either the clutch is bad, or there is a blockage directly ahead of the clutch as it needs hot air to trigger the bimetal strip.

I suppose that changing the water pump might help if it is faulty? I am sorry the link I gave does not give cooling system details --- here is instructions for pump change PeachPartsWiki: Replacing the Water Pump

this is a better link which does give details of cooling system Model 124 Maintenance Manual Index ----- select M103 which is your engine then SECTION 20 cooling system

The fan clutch have big role in this situation?

ALL units act together radiator---fan---waterpump----thermostat---- coolant/antifreeze It is sometimes difficult to know exactly which one is faulty Hope the information in the links helps you.
