how bleed cooling system

I need to bleed the cooling system on my 2106 transit van.
Surprise I don't have radiator plug.
Do you have any suggestion?

Draining

NOTICE: The coolant must be recovered in a suitable, clean container for reuse. If the coolant is contaminated, it must be recycled or disposed of correctly. Using contaminated coolant may result in damage to the engine or cooling system components.

NOTICE: The vehicle cooling system is filled with Motorcraft® Orange Antifreeze/Coolant. Do not mix coolant types. Mixing coolant types degrades the corrosion protection of the coolant. Failure to follow these instructions may damage the engine or cooling system.

NOTICE: Always fill the cooling system with the manufacturer's specified coolant. Chemically flush the cooling system if a non-specified coolant has been used. Refer to Cooling System Flushing. Failure to follow these instructions may damage the engine or cooling system.

NOTE: During normal vehicle operation, Motorcraft® Orange Antifreeze/Coolant may change color from orange to pink or light red. As long as the engine coolant is clear and uncontaminated, this color change does not indicate the engine coolant has degraded nor does it require the engine coolant to be drained, the system to be flushed, or the engine coolant to be replaced.

NOTE: Less than 80% of coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement.


WARNING: When releasing the cooling system pressure, cover the coolant expansion tank cap with a thick cloth.

Remove the pressure relief cap.


Refer to: Jacking and Lifting - Overview (100-02 Jacking and Lifting, Description and Operation).

Remove the underbody shield.




WARNING: Be prepared to collect escaping fluid.

Open the radiator drain valve and drain the engine coolant in a suitable, clean container.
Use the General Equipment: Fluid Container

Filling

Filling and Bleeding with a Vacuum Cooling System Filler

Filling and Bleeding with a Vacuum Cooling System Filler


NOTICE: The cooling system is filled with Motorcraft® Orange Antifreeze/Coolant. Do not mix coolant types. Mixing coolant types degrades the corrosion protection of the coolant. Failure to follow these instructions may damage the engine or cooling system.

NOTICE: Engine coolant provides boil protection, corrosion protection, freeze protection, and cooling efficiency to the engine and cooling components. In order to obtain these protections, maintain the engine coolant at the correct concentration and fluid level in the degas bottle.

NOTE: Add Motorcraft® Orange Antifreeze/Coolant or equivalent.

NOTE: Do not add or mix with any other type of engine coolant. Mixing coolants may degrade the coolant's corrosion protection.

NOTE: Do not add alcohol, methanol, or brine, or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing.

NOTE: Ford Motor Company does NOT recommend the use of recycled engine coolant in vehicles originally equipped with Motorcraft® Orange Antifreeze/Coolant since a Ford-approved recycling process is not yet available.

When adding or topping off the engine coolant:

Measure the coolant concentration in the vehicle.
Use Special Service Tool : ROB75240 Coolant/Battery Refractometer (Fahrenheit)
Determine the concentration desired based on the vehicle duty cycle of extreme hot or cold operating conditions.

Add, top-off or adjust the coolant as follows:

For concentrations measured 48/52 to 50/50 (freeze protection -34˚C to -37˚C [-30˚F to -34˚F]) use Motorcraft® Orange Antifreeze/Coolant Prediluted to maintain a coolant concentration in this same range.
Material : Motorcraft® Orange Antifreeze/Coolant Prediluted (U.S.) / VC-3DIL-B (U.S.) (WSS-M97B44-D2)
For all other concentrations, use Motorcraft® Orange Antifreeze/Coolant Concentrated and/or distilled water to get to the desired concentration.
Material : Motorcraft® Orange Antifreeze/Coolant Concentrated (U.S.) / VC-3-B (U.S.) (WSS-M97B44-D)
When refilling the engine coolant after a flush procedure, use a mixture of Motorcraft® Orange Antifreeze/Coolant Concentrated and distilled water to get to the desired concentration.

Close the radiator drain valve.


Install the underbody shield.


Install the vacuum cooling system filler and follow the manufacturer's instructions to fill and bleed the system.
Use the General Equipment: Cooling System Vacuum Tester and Refiller
Recommended coolant concentration is 48/52 to 50/50 engine coolant to distilled water (freeze protection -34˚C to -37˚C [-30˚F to -34˚F]).


For extremely cold climates (less than -37˚C [-34˚F]):

It may be necessary to increase the coolant concentration above 50%.

NEVER increase the coolant concentration above 60%.

Maximum coolant concentration is 60/40 for cold weather areas.

A coolant concentration of 60% provides freeze protection down to -50˚C (-58˚F)

Engine coolant concentrations above 60% will decrease the overheat protection characteristics of the engine coolant and may damage the engine.


For extremely hot climates:

It is still necessary to maintain the coolant concentration above 40%.

NEVER decrease the coolant concentration below 40%.

Minimum coolant concentration is 40/60 for warm weather areas.

Engine coolant concentrations below 40% will decrease the freeze and corrosion protection characteristics of the engine coolant and may damage the engine.

Vehicles driven year-round in non-extreme climates should use a 48/52 to 50/50 (freeze protection -34˚C to -37˚C [-30˚F to -34˚F]) mixture of engine coolant and distilled water for optimum cooling system and engine protection.


Fill the degas bottle to the MAX FILL line.

Install the degas bottle cap until it contacts the hard stop.

Turn the climate control system off.

Start the engine and increase the engine speed to 3,500 rpm and hold for 30 seconds.

Turn the engine off for and wait for 1 minute to purge any large air pockets from the cooling system.

WARNING: Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may result in serious personal injury.

Check the engine coolant level in degas bottle and if necessary fill to the top of the MAX FILL line on the degas bottle if the engine is warm or to the top of the MIN FILL LEVEL if the engine is cold.

Start the engine and let it idle until the engine reaches normal operating temperature and the thermostat is fully open. A fully open thermostat is verified by the cooling fan cycling on at least once.

Increase the engine speed to 3,500 rpm and hold for 30 seconds.

Allow the engine to idle for 30 seconds.

Turn the engine off for 1 minute.

Repeat steps 16 through 18 a total of 10 times to remove any remaining air trapped in the system.

WARNING: Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may result in serious personal injury.

NOTE: The coolant should be at room temperature when checking the level.

Check the engine coolant level in degas bottle and if necessary fill to the top of the MAX FILL line on the degas bottle.

Install the pressure relief cap.

wow thank a lot for all this informations.

So if I installed a heat exchanger on the cooling system I have to bleed the system with the Vacuum Cooling System Filler?

Some air bubble into my system does not allow me to pump the coolant in the heat exchanger.

i have heard of priming water pumps (not in vehicles) the cooling system should be self priming, all the air usually ends up in the radiator eventually, often rather quickly, remove the radiator cap and keep adding coolant until after the engine reaches operating temperature, put the cap on and check the overflow tank. there must be a valve or a plug still in one of your upfitter lines, did water flow out of both upfitter lines before you hooked up your lines to them? or maybe you could try blowing air thru both lines one at a time with the radiator cap off to see if there is an obstruction in one line, although not know how its plumbed the thermostat may stop the airflow. (things were simpler in the old days Y-ing off of the heater core hoses!)

Where is the pressure relief cap and after removing it does one just turn the drain plug a quarter turn to the right to drain the coolant?
Thank you,

Vacuum air extraction is the way to go-
I've seen cooling systems where you will NOT get all the air out any other way-
I bought a cooling system pressure tester kit years ago with a lot of adapters to fit almost all cooling systems- I use my air operated* vacuum pump through it to suck out any air in the system- takes only a minute or so and you know it is right.

This one is unexpectedly high quality for a Harbor Freight tool and is what I bought>

*I have an electric Air Conditioning vac pump also but I'm not gonna risk sucking coolant through it!
