318 engine overheating
What elevation are you at; Brazil has a huge variation in driveable elevations. That might put a big monkey-wrench in your tuning.
The water thermostat only sets the MINIMUM coolant temperature. It has nothing to do with the maximum.
The maximum temp your engine might run at is governed by the efficiency of the rest of the system,and starts with the coolant itself. Water is the best coolant.
Next up is the pump; you may need to install an anti-cavitation plate on your impeller.
Next up is the fan, and I see you already have what looks like a 6 or 7-blade hi-efficiency all-steel fan on there. and it appears to be in a shroud. So you are good there. But IDK, it sorta looks like that fan is on backwards or it is a reverse rotation type; check it out.
Next up is the rad; water should run out the bottom hose nearly as fast as you can pour it in the top.
And finally is the fan clutch. IDK if you have one, and in Brazil, it might be a good idea NOT to have one. But if you have to have one, I highly recommend a thermostatic type; NOT a simple viscous type.
Check out your fan. Here is what I run.
