Things to check-
1. Water pump area
2. Thermostat housing
3. Coolant lines all over, especially the supply return lines going in to the firewall.

(Had a issue with loosing coolant after getting up to temp). Turned out to be supply line in to fire wall, not seated properly and clamp was not tight.

Hopefully the daylight will shed more light .. it seems to be below tstat housing could be around water pump

I would go take a look at the water pump. I had a similar issue with my 2001 when the water pump was failing.

Hello all so i tracked the problem to the thermostat housing. Changed that all good .unfortunately i did break a bolt off ...not in the head but in the steal sleeve that is molded into the houseing . So i was able to rotate the entire housing and remove the broken bolt from the block . Running on two now no luck finding that bolt yet but also no leak .also found the.broken ground in the door boot and now have working windows wooo hooo . Now i need to figure out why the moonroof only vents and wont slid and the door ajar problem and the front end problems...the list is shrinking. Thank you ..

There is a part number for those bolts. I was going to get them when I did my housing but didn't. I'll try to find it. Also, I have a full thermostat housing with new thermostat if anyone needs them. Not sure if housing is cracked anywhere or it was just the top gasket. The thermostat I had just put in 3 months prior to changing.

Go to www.ford parts catalog. Com . Put in thermostat housing bolts. Everything is in there.
