Yes, you can replace it, according with the thermostat replcement to take off the housing for 3.0L OHV Engine...

CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

  1. Drain the coolant until the level of the coolant is below the level of the thermostat.
  2. Disconnect the upper radiator hose from the water hose connection.
  3. Unfasten the three water inlet connection retaining bolts and remove the water hose connection.
  4. Remove the gasket and thermostat from the water hose connection. Discard the gasket.
To install:
  1. Clean the water inlet connection mating surfaces.
    NOTE The jiggle valve on the thermostat must be in the up position.
  2. Place the thermostat in the water hose connection making sure the thermostat jiggle valve is facing up.
  3. Install the new gasket and place the water hose connection assembly into position.
  4. Install the water hose connection assembly retainers and tighten them to 89-124 inch lbs. (10-14 Nm).
  5. Connect the upper radiator hose to the water hose connection.
  6. Fill the engine with coolant, start the engine and check for leaks.
  7. Stop the engine and top off the coolant recovery reservoir as necessary.

1995 ford f 150 6 cyl leaking coolant passenger side back of block.

As long as you have good access it is easy.
If the leak is from the thread where the sensor enters the block:
drain the coolant, (remove bottom radiator hose)
remove the sensor (use a ring spanner as the sensors are often brass and easily damaged)
apply some thread tape to the sensor.
reinstall (don't do up too tight)
reconnect rad hose
refill with water (when refilling, fill the radiator to the top, start the car, let it warm up, continue to top up the radiator as required. replace the cap, check for any bleeding valves (usually on the thermostat housing if any) open to release air if applicable.

Termostat is as follow. See clarification. R U changing the sensor?
Follow the top radiator hose over to the engine and where it connects to the thermostat housing. There should be two bolts holding the housing to the motor. Remove the housing and replace the thermostat and gasket. The larger side of the thermo goes in the engine.

2004 dodge stratus leaking coolant

there is a temporary fix for this until you can get it replaced, you will need 4 washers wide enough to fit around the lip of the upper half. Remove the 4 bolts holding the outlet and place the washers on the bolts and tighten down lightly enough to prevent leakage, this will fix it on a temp bases only until it can properly be repaired.
