The Easy Way To Bleed Air From Ur Cooling System....

[flake32]

ive heard it askd a number of times on here from members worried about air locks or air caught in their cooling system after a radiator flush or what eva........anyway i just changed my radiator and found my self asking the same question whats the best way to bleed my cooling system...i searched on here and didnt find much....so i tryd running the car with the rad cap off and topping up coolant as needed..did that several times tryd the water bleed valve but it wouldnt really squirt any coolant out and i wasnt convinced any air had come out if any was even in there??????...........CONCLUSION....then after talking with a old school machanic i know he convinced me he had a contraption hed bought years ago to bleed the air easy as..well he was right...now ill try to explain it its a very simple thing and works great......maby others use these but ive never seen one.....................basicly this little kit comes with a replacement radiator cap,.....so u remove your standard radiator cap and screw on the replacement which has a hole in the top with a rubber grommet in it which is the perfect size to take the small piece of plastic hose that sticks up vertical about 600mm and then on top of that a 500ml coolant holder....all it dus is basicly hold the coolant above or higher than the head...there for forcing any trapped air upward and out of the system and at the same time filling up with coolant.......WE managed to top up the coolant holder 1 and a bit times after 10 minuts at iddle so there for another 7-800ml of coolant went in and alot of air bubbles actually did come out......anyone used one??...

If you have the money, invest in a swirl pot.

I have also heard of (not tried) people parking on steep inclines or on car ramps so the radiator cap is the highest part of the cooling system, and letting the car idle with the cap off.

Doesn't have to be that steep...

I use a funnel or half a plastic drink bottle, couple of O rings round neck and jam it into the neck of radiator, open bleed valve and pour away.

What about the factory bleed screw? Seems to work for me.

sometimes even using that u can get air trapped.....

all the methods above should work on there own.....

easy one is to run the engine speed above idle.... say 1200rpm or so..... water pump turns faster and help waterflow/pressure to push air out

good old halfa coke bottle does the trick, raises the water just enough to self bleed it,
