bleeding cooling system??

[fastezz]

I have searched alot about this issue and i just cant seem to find out why but keep trying to bleed my coolant of air bubbles and when i do the thing where you take off the cap and let it run till all the air bubbles are gone just doesnt work, it over flows when i do it. s there any other way to do it. just put in new hoses flushed the whole system, new 180 degree thermostat and when im driving it goes up to the middle point exactly almost cometimes below it but when i stop and it idles it starts to creep up very slowly, know there are air bubbles in the system i need to get them out tommorow for my 500 mile trip so i dont end up stoppiong 20 times to fill up my radiator with coolant after it boils over because there are air bubbles.

In my experience, the DSM cooling system doesn't need bleeding. However, to do it: take off the radiator cap, gently squeeze the lower radiator hose, put the palm of your hand over the filler hole, release the hose, remove your hand, repeat.
You'll notice the filler cap and the hose to the expansion tank are at the highest point in the cooling system. Gravity will bleed the system on fill-up, and whatever air it might miss will be purged by the flowing coolant and its expansion during warm-up.
Make sure the bleed hole in the thermostat is at the top of the housing when installed.

i dunno man. I heard about air bubbles causing problems in cooling systems but the 2 cars ive done work on my old probe and the eclipse now. I have never bleed the cooling system and never seen a problem at all. Your not gonna get rid of all the air in the system, because the expansion of coolent. you always have a little air in the system. So dont worry about it and just fill it up as far as u can then drive it for a little let it cool down and then top off the system. And ur done

if it never overheats while moving, but gets hot while standing still, check to make sure your fan(s) are coming on. They have thier own sensor.

If air keeps bubbling out, even after a day or more of driving, I would think of alternate transportation as those symptoms lean towards head gasket or warped head to me.

I've drained and filled my cooling system SEVERAL times, due to 2 shitty rads, and the regular drain/fill each summer for the track, and I have never had air bubbles problem

It should purge all the air out- the bubbles are supposed to find their way to the expansion tank where they'll rise to the top. The system only pulls coolant back in from the bottom as the heat dissipates, without bubbles.
