good kit at a good price.
if your going to proceed with this yourself then do the following
Make sure you have a new upper and lower hose.
Remove the degas bottle cap.
Remove the drain plug from the bottom drivers side of the radiator with a bucket to catch the rad fluid.
Once drained get under the truck and you will see a connection in the middle remove the clip and separate it from the hose going to the passenger side of the rad. you will take a bath there is no way around it
Now stay under the truck and its a tight fit but you need a pick of some type you will be able to reach up with your arm and get that clip off the lower water pump connection.
The install of the hose is much easier as you just have to press the hose onto their connections make sure its quiet out and you hear that clip snap into its groove. the lower connection in the middle always fights me a bit just make sure its indexed and try to push it together as straight as possible.
Now onto the top hose you may need to tape a pic to a long screw driver or something to get the top waterpump connection the top rad side it easily accessed.
Replace with new hose!
You likely do not have a radiator vac refill system but you also didnt drain the block oil and fuel coolers so you can get away with this method and if your still worried go for a trip to the dealer to have them purge the system of air if any.
Filling and Bleeding without RADIATOR REFILLER
Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level in the degas bottle. Failure to follow these instructions may result in damage to the cooling system. To maintain the integrity of the coolant and the cooling system:
add Motorcraft Premium Gold Engine Coolant with Bittering Agent. Always fill the cooling system with the same type of coolant that was drained from the system. Do not mix coolant types.
do not add orange-colored Motorcraft Specialty Orange Engine Coolant with Bittering Agent (US). Mixing coolants may degrade the coolant's corrosion protection.
do not add alcohol, methanol, brine or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing.
1. NOTICE: For diesel engine, do not add Motorcraft® Diesel Cooling System Additive when refilling the cooling system with new coolant. An excessive amount of additive may cause formation of gels that may cause coolant flow restriction, plugging of passages and overheating.
For diesel engine, when refilling the cooling system with new coolant, verify that the specified coolant is used. Not all coolants contain a nitrite additive package. Failure to have nitrite in the cooling system may result in major corrosive damage to the engine cooling system components.
For diesel engine, when reusing the coolant that was drained from the cooling system, check the antifreeze and anticorrosion level of the coolant. Refer to Coolant Test Diesel Engine in this section.
Failure to block the radiator off will require more time before the thermostat will open. Position a piece of cardboard on the driver's side half of the radiator.
2. NOTE: The degas bottle cap must be loose so that the cooling system does not get pressurized.
Fill the degas bottle to the maximum fill line. Recommended coolant concentration is 50/50 ethylene glycol to distilled water.
▪ Maximum coolant concentration is 60/40 for cold weather areas.
▪ Minimum coolant concentration is 40/60 for warm weather areas. Install the degas bottle cap until it starts to ratchet. Back the degas bottle cap off one-half turn.
3. Start and idle the engine until the coolant level stabilizes. 4. Refill the degas bottle to the maximum fill line.
Install the degas bottle cap until it starts to ratchet. Back the degas bottle cap off one-half turn. 5. Run the engine at 3,000 rpm for 2 minutes. 6. Bring the engine to an idle.
Determine if the thermostat has opened by feeling the temperature of the radiator tubes on the passenger side of the radiator. If the tubes are cool then the thermostat has not opened. If the tubes are warm or hot then the thermostat has opened.

GENERAL PROCEDURES (Continued)
7. If the coolant level has dropped below the minimum fill line then refill the degas bottle to the maximum fill line. Install the degas bottle cap until it starts to ratchet. Back the degas bottle cap off one-half turn.
8. Repeat Steps 5 through 7 until the thermostat opens.
The coolant level will rise before the thermostat opens due to thermal expansion. The coolant level will drop after the thermostat opens due to air exiting the radiator.
9. Repeat Steps 5 and 7 until the coolant level stabilizes. 10. Stop the engine and remove the cardboard from the radiator. 11. Restart and idle the engine for 5 minutes to stabilize the coolant temperature. 12. Fill the degas bottle to 20 mm (0.787 in) above the maximum fill line.
Install the degas bottle cap. 13. Verify that the cardboard has been removed from the radiator.
