    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.

    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.

    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.

    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

      Good call I guess I got lucky because mine never leaked ha ha and I ended up selling the truck anyway.

    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 😉.

  • @Goodhuman_brb
    @Goodhuman_brb ปีที่แล้ว +2

    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)

    • @MotorheadLars
      @MotorheadLars  ปีที่แล้ว +5

      It’s been a while since I did this. Most or all the air should come out of the bleeder screw. I never bothered with the funnel. I left rad cap on while I was bleeding and just topped off the rad after. If you take rad cap off while bleeder screw is open then coolant will come gushing out.

    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? :((

    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

    • @MotorheadLars
      @MotorheadLars  3 ปีที่แล้ว +2

      That happened to me once too. Close that screw before it overheats after the majority of the air is out. Also make sure your radiator cap is on or it will spray out of there. If it still does overheat you may need to start considering a thermostat or worst case, head gasket.

    • @MotorheadLars
      @MotorheadLars  3 ปีที่แล้ว +3

      You could also have blockage somewhere in the system so make sure you’ve got heat coming out of the vents with heater on.

      @@MotorheadLars I had a lot of air in the system because it’s never been bled until I found out about this video. It only overheated after spraying a bunch of coolant out. Possibly draining it to the point of there not being enough coolant to keep the motor warm. I did it a different way and got all of the air out of the system and now I get heat in my vents almost immediately and it runs at a lower temp than the middle tick

    • @MotorheadLars

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

    • @MotorheadLars
      @MotorheadLars  2 ปีที่แล้ว +1

      It will lose some as the air bleeds out of the bleeder screw. So you’ll need to refill when it’s all done. Be careful when opening the cap. If you take the rad cap off while bleeding and bleed screw is open it loses pressure and a bunch of coolant. So If you leave the rad cap on when bleeding you won’t lose nearly as much.
