I Have A 2002 Explorer 4.0l And Its Overheating Really Bad
Ive Change The Radiator , Water Pump , Thermostat(2 Times), Water Bottle Cap , Flushed 4 Times And It Still Overheats
Also It Builds A Lot Of Presure On The Water Bottle And Main Hose
And The Antifrezze Come Out Of The Water Bottle And Its Cold.

I Dont Know What To Do Next, Can Some One Help?

Have you checked the heater core?? Could be an option. Not sure though. Also, maybe perhaps a temp sensor gone bad. Hard to say. Considering what you've done to it already you might wanna have a garage check it out.

Yes, Heater Core Was Check.

I Notice That The Recovery Tank Has Melt In The Inside
Do You Think That Has Something To Do With It.

Alot of pressure build up in the coolant system? Does it build fast?

Could be a head or head gasket pushing compression into the cooling system.

Sounds like a head gasket to me also ,
Get a CO2 coolant test ,
that will confirm a head gasket leak.
Or a cylinder leak down test.
