Strange problem...

Hey folks,

I tried to post this in the 3.0 form, but it would not allow me to post for some odd reason, but it worked here.

I have a 98' 3.0 4x4 Ranger, as noted by previous posts, its got 200k+ miles. Here lately, it will randomly start flushing antifreeze into the reservoir and run the system very low, all the hoses suck tightly together and I lose heat and the temp gauge drops. When it does it, I get out and open the radiator cap and it lets out a load "hiss" and all the hoses reinflate, heat starts working, gauge returns to normal and sucks the fluid back into the radiator over time. Its just started doing it since it has gotten cold out, and it only does it when I first start the engine when its cold.
Any thoughts would be great!
 
Throwing out a wild guess......... Thermostat not opening?
No that can't be it, well maybe....IDK
