next is the heater hoses.. same thing.
remove radiator cap.. can you see the water flowing....?
have you had the cooling system reversed flushed?
thermostat replacement!!!
water pump replacement
lower part of radiator blocked...clogged...
lots of things before heater core issues.

Do your DIAGNOSTICS before deciding what remedial action to take.

just so you know..
I have replaced water pumps with the impellor blades missing 75 percent of blade GONE. not 1 blade, but all of them.
test, inspect, troubleshoot... do it Correctly.. cheaper at the end.

How many miles on the clock? Ill bet its time for a flush anyway. A full system flush should be performed according the the schedule in the owners manual or sooner. My bet is its never been done. Time for an inspection. Replace the T-Stat with a Motorcraft part only. Then while the systems down pull the pump and inspect. Also consider replacing any hoses that look/feel questionable.

ok i checked hoses and top and bottom heater hoses are nice and warm. with heater on one of the heater hoses is real warm and other is just kind of warm. i did notice a slight smell of antifreeze and saw some steam and bubbling from around the cap. does this help with the diagnosis? may just take it to the shop and have it checked.
