Trying to bleed the coolant system as per Bentley's. Watched for fluid from bleeder valve but fluid level does not go down in the overflow reservoir. Tried it with engine running but all I got was air hissing from valve - no fluid. Temp got too close to red so I shut it down.
By the way, all I had done was replace the heater control valve (lost some coolant). Car never overheated prior to this.
Any help greatly appreciated.
