How do you burp cooling system?
Hey guys,
So this stupid radiator flush has been taking me all afternoon/night. Now it is dark and I am working by flash light and I want to get my coolant in and everything working ready so I can shower and go to bed before work.
I was finishing flushing out my system when I noticed while my truck was running both radiator hoses were collapsed flat. I have searched multiple threads and see the advice to "burp" the system but I guess I don't know how to do that.
Can't find it in my Haynes or FSM. I am sorry I am a total noob.
I bought and put on new hoses and radiator cap today.

Jack up the front end, open radiator cap, turn truck on heat full blast, let it run and add coolant when the tank lowers. I also squeeze my two radiator hoses a bit while im doing this to make sure I can hear any air. Im sure HeyYou or Zman will tell ya something better, but this works for me.

Yeah I leave the cap off, yes while it is still running. Rumble truck is right you can drill a small hole in your t-stat to fix this, but that requires more work and mess. Just open radiator cap run truck full heat untill your gauge is up to 180-190 give your radiator hoses a coouple light squeezes and add coolant as the level goes down and it is filling air voids

I've always just filled it up and the expansion tank too, then put the caps on...start it up and let it run until it starts to get to normal op. temp then shut it off and let it sit for 10 minutes, take the cap off and refill. Do it again and let it warm back up and shut it off and check it again after 10 minutes or so. Worked for me everytime. I even drained the block completely last time. My Audi has a cool little valve for bleeding the coolant system as did my old Honda.

Ok, well it doesn't seem to be collapsing anymore but now it won't seem to suck up all the coolant. The reservoir and the radiator are full but I have only put about 4 qts of coolant and 3 3/4 water. I let it run, with the heater on for awhile and drove it around the block a bit but nothing. Guess I will be done for now and keep the water/coolant in my truck and keep an eye on it.
