I have a ford escape 2001 v6,water was fulled in the tank

no year car told, age matters on all machines. all.
all cars run about 15psi , pure physics of hot water expansion and cap pressure regulated.
my guess is you mean the overflow tank on side of RAD,that has exploding steam and water to this side tank? "violently" that be gross overheating
lots of causes and lots of tests. to find it.

• bad thermostat ,10 years is like max. life.
• dead water pump.
• bad radiator
• bad RAD fan. dead. or dual fan 2nd is dead.
• low coolant, sure,after now but is no cure filled and tried. full up in rad dead cold 50%AF MIX.
• FANS BELT MISSING OR LOOSE. (TO PUMP)
• BLOWN HEAD GASKET OR WARPED HEAD(S) CAUSED.
• SIDE TANK HOSES BAD MORE MISSING SUCH THE EVERY COOL DOWN AF DOES NOT GET SUCKED BACK INTO RAD. MAKING IT DROP LEVELS OVER TIME.
• ALL WATER HOSES CAN LEAk or heater core. causing water loss and bingo overheats.

to the inlet hose of the water pump or to housings in the side of the block

Guessing you are saying you checked vacuum lines, the next probable place is the exhaust.
Can you tell where it is coming from? If the front end of the engine then remove belts one at a time to disable accessories.
You need to locate it. Use a piece of fuel line of a hose of some type, you should be able to move it around and locate the source of the whistle.

Junk yard will have one for less but a chance roll the dice

Had this code for over 2 years on my 02 escape. FINALLY, found the solution. DONT replace your egr vacuum solenoid (unless you see broken pins on the connector). You can always test the solenoid to see if it still works if you suspect the solenoid is the culprit. Rather, most likely the problem will be in your electrical harness that connects from the solenoid to the pcm. I had no visible broken wires. However, in my case, my female connector harness that plugs into the solenoid was faulty. Replaced it by soldering the wires from a "new" harness that i got from the junk yard. If this fails for you, the problem will be almost guaranteed to be in either your pcm hardware or a broken pin at the pcm connection.

yes its possible that the termostat got damaged ,ive personaly never seen-it but i guess if it went really hot it could appen how ever try to see if who ever replaced the rad ,it possible that he forgot to plug bach the rad fan

Have you changed the thermostat yet if not this should solve your overheating

The oil pump is located on the passenger side of the car, below the water pump near the bottom of the motor. Easy access is under the car

Check coolant level in the recovery tank, if full probably a bad level sensor. Part of the tank.
