I want to change my antifreeze on my 95 wrx but i'm a bit worried about getting air lock's, so is there any special way of filling up the system without getting an air lock.
thanks,
nick.
p.s what's the best antifreeze to use.

 

when we fill them at work we fill through the top hose first coz sometimes you get an air lock then when it comes out of the hose fill as normal. hope this helps

 

Make sure that the heater control is set to hot when you refil.
