The coolant temp sender that shows the gauge working temp is mounted below the upper radiator hose.It is mounted below close to the thermostat housing.It has a single wire terminal that slides on the connection.To replace is simple,drain coolant down enough so no fluid is in the upper hose,unless you plan a coolant flush(I recommend) unless your coolant is less than 3 yrs old.Now take terminal off,unscrew sender with a wrench.I suggest using some permatex high temp thread sealant(sold at auto zone,advance,napa) in a white tube.Place a small amount on the threads of the new sender and install snug,do not over tighten.Connect electrical plug,refill coolant system,and bleed air off,with truck at idle temp selector on heat,fan hi for 15-20 leave radiator cap off until coolant starts to bubble over then put radiator cap on.You might consider replacing your thermostat at this time as well and use a new gasket.If your hoses are over 4 years old replace those too being winter is coming,and are prone to failure on temp change hot,to cold either way.

If you are referring to the coolant temperature sensor which sends signal to your dash guage and controls when the radiator fans come on refer to the following website if you have a 4 cyl vehicle. http://www.mazdaforum.com/archive/threads/coolant-temp-sensor-how-to-replace-pix-4746-1.html
The engine oil capacity for a 1986 Mazda B2000 is 4.1 quarts.
The coolant temp sensor for the gauge is located near the front passenger side of the engine near the thermostat. It will be pointing slightly down and to the front of the truck. Will have a single yellow wire attached. The coolant temperature sensor for the ECU is bolted into the intake manifold in front of the carb. It will have a green 2 pin molded body. A 3rd sensor is located in the bottom of the radiator, this turns on the Carburetor PTC heater when the coolant temperature is below 60 deg F. Kyrasis6 Owner of Mazdatruckin.com
The 2003 Mazda engine coolant temperature sensor is located on the front of the engine, above the thermostat housing. The sensor will have to wires leading to it.
I believe the carburetor is a Mikuni. I have a 1986 B2000 myself.

At the back of the engine on the coolant outlet that goes to the heater hoses on the firewall.
