Question about Cars & Trucks
Better see a well qualified mechanic or your Ford Service center before the engine fails and you have to replace it.
PS - Never, ever put plain water in the cooling system. Because of the load today's engines put on the cooling system (trans coolers, A/C, etc.) a 50/50 solution of coolant - available pre-mixed at supermarkets, auto stores, etc. - is required. After you get it fixed, carry a bottle of the 50/50 mix in the trunk for future emergencies.

if our engine run at 82 celcius there no reason its start boiling when you turn it off its normal for temp to raise when you turn off the engine but to start boilling thats mean our temp is higher then 84 degre check our gauge manuelly check the temp with a thermometer directly in the radiator and compare with the gauge that mean the faster you go colder its get so the radiator does its job but what weird it goes up at lower speed so not enought air goes trough the radiator are you missing a front spoiller that redirect the air to the radiator if you raise the boots you gonna have to raise the cooling capaciter of the car check it out let me no. . pierre

Bad coolant level sensor in the tank. Look around the bottom of the reservoir and find a plug connection, unplug it and see if the light goes out. I think the tank has to be replaced dont think you get the sensor out. You could try by take the tank off and see if it will come out of tank but I dont think it will.

Make sure the radiator pressure cap is the correct one and that the hose is not soft--check the lower hose and heater hoses for softness as well. They should be firm, but not hard or cracking. The temperature sensor is reporting normal operating temperature, so it and the thermostat are working correctly (hot water would blow out of the radiator if it were stuck). Check the cooling fan for free turning and no noise. Check it's grounding connection. Check the fuse box for blown fuses to the fan and to the A/C compressor. Make sure all the relays and fuses are firmly pressed into their sockets. Check the A/C compressor clutch winding for resistance--should not read infinity. Does the blower motor for the heater/A/C run when either is turned on? The A/C switch on the dash may be defective.

try replacing your temperature sending switch. That it what tells your gauge or idiot light where to read or light to come on. It may have a short in it. Or a short between the two.
