IC Pump/Line problem

[Dr.Evil]

How does one properly bleed the air out of the IC lines? I have been messing with it for the past few hours and can't get it to flow.

I just replaced all of the IC lines and re-routed them and verified they all flow fine.

I tested the new high-flow pump by sucking up some water from a jug and it flowed like a hose.

I verified both front IC's flow well and the upper tank is free flowing.

I just cannot get the air out of the lines. Whats the trick? I am really getting fed up with this whole thing. I searched the forum and from what I have read, it should just flush itself out. I have the whole thing apart, and I can't get it to clear the air out even by bypassing both front coolers and just looping it from the upper tank, into the pump, and back to the tank. Whats the deal?

I used a radiator pressure tester. Turn the IC pump on then pump alittle pressure into the system.
BTW I would never try to get the air out without clear lines, you will go insane first.

Pull the upper IC off of its supports and tip it straight up, this will help the air vent. You may have to leave the pump on for a LONG time. Are you sure you dont have any kinks in your lines?

I actually had to stuck a piece of vinyl hose to the filler, hooked it up to a shop vac to help suck the air out of the lines...kinda wierd but it worked!

Re: IC Pump/Line problem

first off, check for leaks 100 times over, you'll think you have none, see none, but you'll likely find one.

second, above adivce is good, remove the upper IC and hold it up to allow for water/coolant to flow down.

you can also bounch the truck up and down a bit and it may wiggle some air out.

probalby best thing i do is just have to fill it up a little by little every day if you can't get the air out. i'll work its way out, and you'll see you have more room to fill her up a bit every day.

the whole system isn't the best anyway, but hell, if it works, its good for 11's or faster.

Re: IC Pump/Line problem

I remember that after driving it around the block when trying to fill it last time that the level dropped down. I did it a few times and it filled it up but it didn't flow. Well tonight I saw that the factory pump connector was switched around and it wasn't flowing. So now it is flowing the right direction I just cant get the air out.

Ill put everything back together tomorrow and try just fill/drive around the block/fill and repeate tomorrow.

Re: IC Pump/Line problem

if you have the IC lines rerouted then you should be able to lift the upper IC out and hold it up. May need someone else to pour the coolant in. Or you can pour it in, then lift it up, set it down, pour it in, and lift it up etc etc. Have the pump running while doing this as well.
