how do i purge the collant system of air.

 

i think you do it like this:

1)fill radiator with coolant while engine is cool.
2)keep cap off and start car.
3)it should gurgle and bubble.
4)when the fan turns on and then back off again, top off the radiator, and put the cap on.

someone correct me if i'm horribly wrong and this guy **** up his car

 

thank you sir

 

My D15A2 has a bleed valve where the upper radiator hose meets the engine. If you don't have this you can jack up the front end of the car to make the air come out the system (filler neck) easier.
