Is there a bleed screw/ valve on 1997 Ford Escort cooling system?
there is no bleed screw, if the system is air locking after draining you have possibly got a problem, allow the system to cool down, remove the exansion tank top and fill to the max mark with water or coolant solution, with the top still off start the engne and allow it to tickover-do not increase revs, do this for approx 15/20 mins, the temp gauge will begin to rise and purge the air from the system,refit expansion top and ensure it is tight,continue to run engine until normal temp is attained ,now check the heater is blowing warm/hot air.this may clear the problem.
