Hi wonder if someone can help me i have a mazda 323 and i just wana no if there is a bleed screw to help get the air out the cooling system.thanks for your help john.

 

sorry there is no bleed screw for the cooling system ...here is what i did ...
1 ... remove the rad cap .
2 ... make sure the heat control is at max heat (you may want to open a window)
3 ... get a funnel that will fit into the rad opening and wrap a rag around the base of it .
4 ... keep some anti freeze close by to top up the rad
5... start the car and let it warm up till it reaches operating temp.
6 ... keep an eye on the rad .. when the thermostat opens you will get bubbles and the level will drop .
7 ... it may take a while for the air to purge out of the system my 323 took about 35 min...
8 ... keep the system topped up . you may get some spillage . wear some gloves so you don't burn your hands..
9 ... to help it out squeeze the upper and lower rad hoses to help the air escape...
10 ... let the thermostat do its thing several times .. when it opens the antifreeze water mixture will swirl around in the funnel you installed in step 1..
11 ... after its done . shut off car and reinstall the cap and you're good to go .. this may take several times ...good luck...
