If the thermostat is broken in the closed position the engine would overheat rapidly. If it was broken in the open position the engine cooling system would not reach normal operating temperature and the heater would produce only warm air. Take the thermostat out and put it in a pan of water on the stove. When the water gets to around 200 deg F, the thermostat should open. If it doesn't it needs replaced. Observe carefully that you have not installed the thermostat upsidedown.
yes. but there are several other things that can cause it to overheat. not enough coolant, bad belt, radiator blocked, bad thermostat,bad water pump to name a few.
check the fan or the water pump belt it may be broken if not the thermostat may be stuck you may need to replace it
could be fans not working, thermostat, blown head gasket, broken or leaking coolant lines, bad heater core
If the coolant is brown, it has broken down and needs replaced. You could also have a failed thermostat, plugged radiator, inoperative fans,...........
Before replacing the thermostat, it is worth checking to see if the blend door is broken or the blend door actuator is failing. The most common issue relating to thermostat and climate control in Ford Windstar vans is the blend door. CHECK TO SEE IF IT IS BROKEN BEFORE REPLACING OTHER COMPONENTS (i.e. Thermostat, heater core, etc.). The Blend Door actuator on the Ford Windstar can be found by removing the glovebox. A broken blend door actuator is almost as common as a broken blend door itself. Typically, the fix requires disassembling the entire dash and replacing the whole plenum box, which can be a costly repair. Linked here is a video from www.heatertreater.net demonstrating how to access components of the plenum box for repair without disassembling the entire dash.
Probably it has either run out of coolant or the cooling fan is broken. Some large engine cars in really hot weather need a larger radiator fitted so it doesnt overheat....like driving a v8 around town in the summer in Spain for instance.
if its not working.
Your water pump might be broken or your thermostat might need to be replaced. You obviously don't have a leak so somehow the fluid isn't moving through the engine. If the thermostat is broken it will not let fluid into the engine and then the engine will overheat and the radiator will release smoke.
Before replacing the thermostat, be sure to check your blend door for functionality. The most common issue with heat or A/C in the late model Ford windstar is a broken blend door. A broken blend door actuator is almost as common as a broken blend door itself. Typically, the fix requires disassembling the entire dash and replacing the whole plenum box, which can be a costly repair. demonstrating how to access components of the plenum box for repair without disassembling the entire dash.
That depends. If the thermostat is stuck shut. the engine will overheat and damage can occur. If it is stuck open you can drive for a while without hurting anything, however. you may not get any heat and driveability problems may crop up because of misreadings of coolant temp sensor.
because you will do major damage to valves and pistons. they will all need replacing . or at worst engine replacing
To open a door on a 1998 Avenger that has a broken handle, a person might have to use another door to gain entry to the vehicle. Then the door can be opened from the inside.

Thermostat may not be opening to allow coolant to flow through heater box. Thermostat may be opening too soon allowing cold coolant to flow through heater box. Either way thermostat needs replacing
It is not a defininte answer. It could be as simple as a thermostat. If the battery light is on, then it could be a broken or slipping belt. it could be a bad water pump. It could also be a blown head gasket. More than likely it is one of the first two. Start with the thermostat.
Follow the upper radiator hose to the engine... you'll want to remove that metal plate that holds the ignition coil to gain access. I suggest replacing the bolts that hold the thermostat housing to the engine, they have broken on me when I replaced my therostat. Had to drill them out when I foolishly reused them.
By replacing it.
it should be replaced when it stops doing its job controlling the temperature and replacing the battery does not solve the problem or it is showing a digital error code that tells you it is defective. You may also want to test if it actually is doing its job but the heating or cooling unit may be broken. If you have more than one zone and you know what you are doing, you can switch it with a known working thermostat and see if the problem stays with the zone or it moves with the thermostat. That should tell you if the thermostat is broken or the system related to that zone needs maintenance.
A broken spring retainer in the shifter.
There are numerous things that can make a car overheat. It's possible the coolant level is too low, or the electric cooling fan may have gone out. Another possibility is that the thermostat may need to be replaced or the radiator fan switch may not be working right. The car will also overheat if the fan belt is broken or if the radiator is plugged up.
one of the things that could be casing your ovreheating problem is a stuck thermostat. The thermostat stays closed until the engine gets to a certaqin temperature and then opens up to cool the engine. if the thermostat fails to open no coolent gets to the engine therfore causing the engine to overheat. one way to tell if your thermostat is going out is your upper radiator hose where the themostat housing is will be stretched and feel kinda rubbery. hope this helps could also be that your water pump is going and or a broken water pump belt...but id go with the thermostat first.then take it from there.
Broken thermostat. Common Chrysler problem. Replace the thermostat.
The extra load imposed by the air conditioning compressor is overheating the engine. This could be caused by numerous things, but the most common would be either a broken thermostat, low coolant, or a badly tuned engine. Take it to a mechanic.
