Start with the sensor on the engine. Then the relay. From there, I would take a look at the guage itself.
SOURCE: Radiator fan won't kick in
On my slightly older Saab the radiator fan is electric and only is engaged when the temperature meter reaches 3/4 to the top.
When the car is in motion it will not spin since the air flowing through the radiator from the speed is sufficient to maintain normal engine temp. Only when the car is still it for a few minutes it may start to spin especially during summer, it will sometimes continue to spin even after the engine is turned off. This is normal behavior for this car.
To conclude, if your engine temp only goes up to half the gauge there would be no need for the fan to start spinning. If it doesn't engage during the conditions I described above there would be a problem that needs to be fixed.
SOURCE: Overheating problem
With the sensor unplugged and the fan works,, replace the new sensor,,,,, it is probably defective. I have seeh this before.

I had this exact same problem -- for about a year and a half! Replaced thermostat, replaced sensor twice, replaced overflow tank, replaced radiator cap, placed a grounding kit on the car in case the problem was electrical ... and was ABOUT to replace thermostat again and then the water pump when a new mechanic suggested we bleed air out of the cooling system. The heater core was PACKED with air, as was the upper hose valve area. Previous mechanic had been using a pressurized fill device to bleed the system and this had just been backing air into the heater core. There are two valves under the hood for bleeding air -- one on the heater core and one on the upper hose. It only takes a few minutes to fix this!

There's a number of possible reasons.
You don't mention if the engine turns over in the attempt, and you don't say which light is on.
A SsangYong service person can plug in a diagnostic tool to see what error codes are present.

I dont think the coolant is boiling, I think you have an air bubble in your system wich is causing a air lock and youll need it flushed out. Your reservior cap should be tight always.. never loose this is an air tight system and your allowing it to get air in it. I have a 2002 linc ls and just had to pay 1000.00 to replace the system because I let an air lock go for too long and had so much back pressure I blew up my reservior.
Testimonial: "Thanks a lot. I've changed the coolant reservoir and reservoir cap. now it seems everything is ok with my car. so, your advise was really helpful."
