10000rpm Posted December 13, 2012 Share Posted December 13, 2012 Does the fan stay on all the time? Maybe the ect sensor has gone bad and may need replacing Quote Link to comment Share on other sites More sharing options...
civicturbo79 Posted December 14, 2012 Share Posted December 14, 2012 This are always a pain in the a*s to bleed up . Drain the system and start again . Take you coolant and add boiling water to it so you have a 50/50 mix as you should and the fill the system. This will open the stat straigjt away forcing the air out of the rad . Run the car with the rad cap off and the heater on full and on hot till there is no bubbles coming out of the rad cap. Then refit cap.Rich.
