Replace any soft hoses.
collapsed hoses cause water flow constriction
.that increases temp fast
to bleed air out of the system . if no air bleeder as such
with heater on full .-engine running
loosen the bypass pipe for the closed thermostat till only coolant flows no air bubbles
check if
the engine cooling fan spinning fast enough
the water pump in good condition
the interior directional flaps motors or actuators working

Good Day,
Sounds like the thermostat is working properly, the only other cause for the valve/lifter noise could be the oil pump is not pumping enough oil up to the top of the motor. I suggest doing an oil change(if you haven'y aleready), be sure to flush several quarts through, after sitting for 5 years I'm sure the old oil is pretty sludgy, this well help rule out this possibilty. As far as the water pump goes, It either works or doesn't typically when they are on there way out the will leak from the gaskets. A bad head gasket would cause white smoke form the exhaust as coolant get's into the oil and is burned off, so I don;t hink this is the problem.
Here's a start for you, hope this helps and good luck

try to run the water pump without hoses, and add water in the 'in' side, if is powers out the other side, then it's fine. how is your water/coolant mix?

Is your temperature gauge working now? That is of more concern then your heater as you wouldnt know if your engine was overheating until its too late. Your heater core could be clogged, they get clogged quite easily. You can flush them or replace. The part is inexpensive but on some models you have to take out dash to replace them, but on other models it only takes about 30 mins and a few bolts.

Hi there. It sounds like you have done the most obvious checks and I can assure you by-passing the heater core will have no effect. There are three possible causes that you need to investigate further and you will need specialist equipment for it - you either have a hair-line crack in the head or cylinder wall or it might be that the head bolts are stretched and therefore weakened and so need replacement. To help you identify these aforementioned possible problems, you might need a specialist fluid that you put into the cooling system which changes colour when combustion chamber pressure enters the cooling system, you need to contact your local Ford Dealer for this - but then you still have the three possible problems to deal with - cracked cylinder wall/s, cracked head or stretched head bolts. Hope this helps, Scottech.

have u bled the cooling system ?warm the car and cut the car off right before the fans come on ,let sit for 30-35 minutes,see if the coolant drops in res. if so repeat process untill coolant stops droping ,then drive car regularly if overheating stops ,but monitor it because it will drop somemore/there has been reports of new and rebuilt water pumps nt having correct propelar mounted on them/ backwards etc. if this helps let me know [email protected]
