Bleeding the air from cooling system in your Dodge 4.7 L engine

Just a quick video explaining how to bleed the air out of your cooling system a very important procedure especially on this truck.

Also folks remember to use only coolant that is HOAT coolant. It is usually orange or red. Whatever you do don't mix the orange or red coolant with green coolant it will cause you major problems in the future. It plainly states this in your owners manual.

The bleeder screw is superfluous on vehicles, like yours; that have the expansion tanks. The 4.7L comes with the bleeder screw because the engine is sometimes used on vehicles that don't have exspansion tanks. You can help it along if you pop the expansion tank lid when full cold for the first few days after refilling. Make sure you run the heater until it puts out hot air. If it doesn't, you may have a clog in the heater core. When gas no longer escapes when you pop the lid at full cold, you're done.

Dude you forgot to put thread sealer on the bleeder screw cap!!!! Under that high pressure it's both called for by the manufacturer and necessary! Also, for anyone else reading: the bleeder comes off with an allen key. It may be necessary to create a larger lever to crack open the bleeder, as in my case. Finally USE THE LARGEST SIZED FUNNEL TO AVOID LOSING ALL OF YOUR ANTI-FREEZE. You can actively pour coolant into the funnel: the added hydrolic weight will tend to also help push out the air bubbles

Thank you. This is the exact information I needed to solve a problem for my customer.

Thanks for the advice, it sprayed a little bit but I let it cool down and did it again and so far so good. We have heat.

Update, I ended up selling the truck and the person who bought it said it had a blown head gasket after they drove it home. I guess that’s why I had air in the system. But as long as I bled it every so often it didn’t seem to be an issue so it must’ve been just starting to go bad. I had it in the shop right before I sold it and they said the head gasket was fine so 🤷🏼‍♂️. Either way I got much more than I bought it for and it had 250 K on the Dash so i got my $$$ worth. I upgraded to a ram rebel with a hemi now 😉.

I done this today on my ram 1500 and my heat isn't very hot. Guess I still have some air in the system. I've let it run with the blender screw open for 30 minutes

How is no coolant coming out of that bleeder hole with the bolt out?...

[rolland]

Will it blow the motor if you don’t let the air out??

[brandenearle]

Thanks for vid. So you don't need to do the funnel/burping method?
Also when bleeding air through bleeder bolt do you keep your radiator cap tightened on through the whole process and just top off radiator fluid at the very end?
(I left rad. cap on because fluid was gushing out of both ends with both open)

Hi, I have Jeep WJ 4.7 today I tried to remove all the air bubbles, it took me 2 hours and I couldn't remove all the bubbles, I had to leave. Do I have to repeat this later? Is this sure to help remove all the air bubbles? But maybe i have head gasket leak? :((

My truck radiator doesn’t have the Radiator Cap just the Reservoir Tank do I also leave it closed while the bleeder is open?

My truck heats up at idle like over, almost to red, I just replaced the thermostat and filled it and bled the system but still over heating

[calinsteele]

I did this exactly but it overheated in the process and started spraying out coolant and I had to shut off the motor and now I’m kinda lost on what to do

[jgmopar]

How do people take the set screw out and not have the geyser of water flowing out? Mine turns into a geyser. Do you only fill the system half way?

[jaimejay]

My heat is hot. But for some reason my 04 ram is only taking 4 quarts of premix

[stanleyjohnson]

Where can I find a new engine coolant bleeder screw for my 2013 ram 1500 4.7l engine, mine is rounded and I can't get it off

[brovie]

Mine keeps bubbling even after 20 minutes.

[worleycole]

So keep rad cap on? Won’t it loose coolant?

BELIEVE ME SO PEOPLE ! Many times it's not as easy as it sounds or as it looks . Bleeding job might not always be the problem for overheating vehicle's and many time's the Bleeding plug screw can be old stripped or junk very tight and a pain too unscrew
