93 Escort No Heat

[skitzo315]

I have a 93 Ford Escort LX and I am not getting any heat. I had heat last winter but this summer I rebuilt the engine. New heater core, thermostat and waterpump. Come this winter I have VERY little heat. I wouldn't even call it heat. I replaced the thermostat once again to see and still no heat. I feel the hoses leading into the heater core and they don't feel hot or really warm. What is wrong with my car?

Does the upper radiator hose feel hot ? If not I'd suspect a defective thermostat. If it is hot try removing the heater core hoses and flushing the core with a garden hose. Give it pressure with 5 second bursts both ways and see what happens.

I am having same problem,have replaced thermostat, flushed rad and heater core , new antifreeze (50/50). My temperature gauge barely comes off cold. Placing the defrost fan on high on cool days actualy cools the engine temp. I am suspicious of the block in which the thermostat resides between the engine and the top rad hose. There is a small port beside the thermostat opening in this assembly which has like several small plugs visable from the exterior view. I do not know its function (temp relief, pressure relief, freeze relief,????) I suspect the engine rad fluid is bypassing the closed thermostat to the main rad. The top rad hose feels warmer than my heater core hoses. I am hoping someone out there knows the solution
