I have a S70 TDI.
Take off the engine hood. This the large black hood that hides the engine bits. It's held on by 4 bolts at each corner.
On your left hand side follow the black thick hose pipe from the radiator to the engine. At the point where it goes into the engine there will be a sensor just above.

The Volvo 850 has two horns in front of the radiator, lift the hood and their they are.
It is located in the intake pipe between the MAF sensor and the throttle.
It is located in the thermostat housing assembly located on the block behind the alternator. It nor the thermostat are serviceable by themselves. It only comes as a unit, which is the thermostat, the sensor and the housing. Part # 31293698 and gasket part#8636573

upper rear right corner of the radiator and/or attached to the radiator hose. If it has an electric cooling fan in front of the radiator, the relay is a black rectangular 4 pin located on the bracket next to the left shock tower. If you are asking about a relay for the blower fan in the car, there is no relay
Inlet tube going into intercooler radiator (front of car, driver side).
If what you're referring to is the temperature sensor, (so that you get a readout in the instrument cluster), it is located just below the radiator hose that attaches to the engine. (On the left upper side as you look into the engine compartment). It is screwed into the 'gooseneck' of the upper radiator hose. I recently had to replace mine, as it made the vehicle difficult to start, with lots of black smoke once started. Now it is fine after the replacement was made.
The 850 does not use a MAP sensor. It uses a MAF sensor that is located and attached to the air filter housing lid
The cooling fan relay switch can be located on the back of the cooling fan motor. The relay switch should be labeled as such.
On the right side of the throttle pedal
