I'm not sure the thermostat is the problem. If the thermostat was stuck open the engine would not warm up and also not overheat.
If its stuck closed, the engine would warm up as well as the heater, then continue to the point of overheating.
If the cooling system is low on liquid coolant, or the water pump is not working, the coolant will not flow thru the heater and the sensor may not know to turn the fans on.
That is normal, it will not get hot without the thermostat. The water cools in the radiator and falls to the bottom and the bottom hose is cold. This is what cools the engine and stops it from overheating.
No, that person is correct and hopefully it's just a gasket. Usually a Norstar Engine overheated isn't too healthy and you may need a cylinder head or two. It's nearly a 20 hour job when it's all done (just 4 gaskets). If you like the car perhaps a used engine may be cheaper.
Clarence, your mini-cooper may just need a new thermostat. if the thermostat in your car is the original, then 4 years is a goodly amount of time for any thermostat to last. Thermostats fail in 2 ways: (A) stuck open, which causes engine to warm really slowly, and (b) stuck closed, causing overheating and causing the heater to blow cold air - since the heated coolant can't get past the closed thermostat to circulate through the heater core (a small radiator-like device used to heat the interior of your car). Your car's thermostat has failed in mode (B). Your cost: $5-$15 at any auto parts store. Project complexity: any handy person could teach themselves to replace a thermostat.
That's weird - it seems like the thermostat is open when you start the mini-van (its supposed to be closed at engine start-up), and then the thermostat closes as the warms up (its supposed to open).
If you can replace thermostat, that may be the thing to do, since these thermostats often cost less than $10. Once the T&C has a new thermostat, see if the heater behavior improves, if so, discard the old thermostat.
Also, if your thermostat is actually behaving the OPPOSITE of a normal thermostat, then you're at
risk of burning up (overheating) your engine - on any trip longer than the commute to work. An engine at operating temperature needs to circulate coolant to/from the radiator (and/or heater core) to avoid overheating. So thermostat replacement may save your entire engine. In the meantime, your T&C will avoid self-destruction only if driven REALLY short distances.
make sure your coolant level is not too low.if all is good sound like water pump bad.check fuse controls heater and ac controls.if fuse looks okay.you have a faulty heater air control air flap motor.or electrical problem to heater air control air flap motor.also check engine oil if it looks like milk shake.you have a blown head gasket it will cause over heating problems.
run it and let it get hot (not to the point of overheating just let it warm up to normal or slightly above normal). put your hand near the upper radiator hose, if you feel not heat, touch it, be careful as it may be hot. if it is not hot at all but the engine is warmed up it is the thermostat, the thermostat is located where the upper radiator hose connects to the motor, usually a 2bolt metal fitting, if this is the case just replace the thermostat.
