If you haven't already ruined the engine, check to see if there is any coolant in the rakiator. DON'T OPEN THE RADIATOR CAP WHEN THE ENGINE IS HOT. But when it is cool open it bp pressing down on it very hard and turning it counter clockwise until it is loose. Fill it with coolant and water. Then check the fans to see if they come on when it starts top get hot. Red means stop and I hope that you haven't hurt the engine. I agree with the previous answer of checking your radiator fluid (only when it is COOL!). Driving with the thermostat will blow your engine. If you've checked your fluids and they are at the correct levels, try also having your thermostat checked -- it may be reading incorrectly. If there is nothing wrong with the theromstat and you have adequete fluids in the resevoir, then it could be a loose or improperly attached radiator hose needs to be tightened or replaced. Another alternative is that you may need to replace your entire radiator (though if you've been driving around with the thermostat needle in the red, changes are you'd need to replace your whole engine -- driving around like that causes a lot of damage to the engine components -- melts hoses, belts, burns away oil and other fluids, and puts you at risk for engine fire.)
Could be the thermostat not opening
Check coolant level Could be thermostat is not opening Could be a bad water pump
You could have a problem with your thermostat in the car.
Thermostat sticking. Replace thermostat and gasket.
dose the electric fan run if not check the relay if it runs check the water pump

There are signs that there is a problem with a hot water heater. When you cannot get your water to heat. It could be signs that the pipes leading to the heater are leaking. It could be a problem with the thermostat in the heater.
Could be a bad thermostat not opening and allowing excess pressure build up
Could be low on coolant or a faulty thermostat.
That definition means that for some reason the PCM is seeing a low input from the ECT sensor. That could be sensor problem, a wiring problem, or a PCM problem, but the most likely problem is that the truck is actually running too cold. That could be a stuck open thermostat, or an incorrect temperature thermostat installed.
Usually a problem with the emission system - have vehicle scanned to determine the problem
Could be a problem with the thermostat housing or it's gasket, could be a problem with intake manifold gaskets, could be a problem with heater hoses or the fittings that screw into the manifold.
How does the van run? It could be the headgasket, if you smell a sweet smell from the exhaust then its the headgasket. If not check the Oil, if theres like, water and stuff in the oil then it could be the headgasket still. The thermostat wont make it lose cool unless theres leakage around the thermostat housing gasket.
Could be thermostat opening and closing adjusting to coolant temperature Could be a bad temperature sensor
sounds like your thermostat is stuck closed, maybe some of the debris loosened from the flush is blocking it.
check the connections behind the gauge they could pop loose
There are a few things that could be causing your 200 BMW 528i to overheat. You may not have the correct mixture of coolant in the vehicle. The problem could also be your thermostat. Have the thermostat checked out to ensure that it is working as it should.
Thermostat is stuck open.
It could be that your head gasket is blown.
When service engine light is on on a 2003 Chevy Trailblazer, the problem could be a faulty thermostat, a circuit range performance problem, or any other problem.
Yes. I got a Taurus 93 and has the same. Very poor heating air inside the car in the morning. Also the temp gauge was always at the very firs line at the bottom. Solution: my mechanic changed the Thermostat. And the problem was gone ... by the coolant :-) Explanation: a bad or failed Thermostat is always in "open". So the water circulate freely and getting colder every moment when pass troght the radiator. A good thermostat only let pass a little part of the water when the engine is cold - in other words it works almost "close".
Could be the thermostat it's stock, replace it.
somthing is out of ballance or lose. it could be a U- joint or motor mount or a wheel. If non of those are the problem then it might be an internal problem in the tranny or engine itself but Always check the simple stuff first.
if your car over heats alot then that is a pretty good sign. aslong as it isn't your water pump. but thermostat is a good place to start. if you replace the thermostat and it still over heats. (assuming that is why you are asking) then it could be the water pump.
