Try to replace the coolant temperature sensor or disconnect it to see if it affects the gauge.
If the gauge is bad, then grounding or ungrounding the connector should operate the gauge needle.
Otherwise, the gauge is bad, or the wiring or connections to it at the harness.

Iv got vauxhall zafria model 2004 outside temperature symbol is not coming on dashboard is that a big problem should take it straight to gargage


No outside temperature just shows the temperature outside the car the snowflake symbol will not show up until it is cold enough outside it has 2 stages yellow is an initial warning of cold temperatures when it gets to freezing the symbol will turn red.
The outside temp warning is not connected to anything mechanical only the engine temerature gauge is so dont worry it will not affect the running of the car but is just there as a warning of falling temperatures outside.

Why does the radiator fan come on when the cars not started, 325I bmw 2002


If it's after you've driven someplace, the car will do this on it's own. It's to bring the coolant down to a lower temperature...a lot of cars will do this. It's just to finish cooling the car down. just don't put your hand near the fan, it might go on suddenly..

My 96 roadmaster dont over heat but temperature gaugs get high


Remove the radiator cap and run the engine until the condition appears. Then use a thermometer (available from most auto parts stores) to check the actual temperature. This should tell you whether or not the gauge is off. If it is reading too high, I would try replacing the temperature sending unit, which is probably located on intake manifold. Most radiator shops can do this for you and will have t he thermometer on hand, in case you don't want to buy a one use tool.
If the temperature reflected the thermometer is approximately where the temp gauge shows, I would then look at the radiator. If it hasn't been serviced regularly, try a back flush. You can get a kit for this from any auto parts store.
If that does not solve the problem, you are likely looking at having the radiator "rodded out". This involves removing the top and bottom tank from the core and clearing out the individual tubes that make up the core. If you are unlucky enough to have one of the newer radiators that has a composite top and bottom tank, you will probably need a new radiator. (Sorry about that). That is easy to check. If the top tank feels/looks like metal, you're probably in good shape. If it feels/looks like plastic - well, what can I say? Good luck.

Temperature needle stays on the hot , have changed temperature sensor but it still stays on the hot and the engine is not overheating or leaking anything..what is making it stay on the hot


replace the thermostat,, and make sure that the fan engages , just because the fluids don't boil over doesn't mean the temp isn't to high, if your saying that the temp gauge is stuck on the hot setting, and doesn't move even when the car is cold,, thats a different problem,, if thats the case whats the make , model , and year

Overheating fan not coming on


Change your Fan Clutch. If the fan is not kicking on to move air through the engine compartment then it needs to be replaced.
The fan clutch is attached to the front of the fan (the part of the fan that is closest to the radiator) it usually looks like a round piece of metal with fins on it. You don't have to take off the fan shroud or anything if you dont have to. in most cases you can squeeze your hands back behind there to get at the bolts securing the clutch to the fan. you may have to take the fan off as well. Hope this helps. Good luck.

It hit the temperature rises to over half


How far over half? The idea that 220 is overheating is wrong. But I don't think your gauge shows numbers if I recall.
Check your engine driven cooling fan. Look at the fan clutch front and back. Is it moist and dirty? Oil from the inside may have leaked out. With the engine off of course, spin the fan by hand. Does it spin real freely and continue for a second or two or more after you let go. The clutch may be bad. What can happen then is the motor will spin faster than the fan and at time the fan will barely move and that would not draw air through the radiator cooling fins.
Also make sure the radiator and condensor are free from debris (leaves, dirt, birds, cats, etc.)

Have a 1996 buick skylark, temperature gauge is running hot - losing antifreeze but not seeing anything on the ground? funny smell. car running fine. nothing looks disturbed under the hood. any...


if you don`t see any coolant on the ground then you could have a bad head gasket that is leaking into the combustion chamber and being burnt,this will also cause a smell.it could be an external leak as well you don`t say how often you have to top up the rad.the leak may be running down the side of the block and being evaporated before it hits the ground and causing the smell.you should have the cooling system pressure tested to see if anything shows up and have a combustion chamber test done on the cooling system to check for a bad head gasket.

My cars heat gauge keeps going up to the hot section, but I don't think the car is actually overheating, I can't smell anything or hear the radiator boiling.


check the real value of the temperature sensor with a scan tool. Compare it withe the value in the gauge. It can be a defective temperature sensor or a damaged gauge...or else the car is really overheating

The gas and the temperature gauges don`t work. they don`t move at all, it shows like the gas tank is empty and the temperature in the same position


Sounds like the dash module is bad or has a bad ground connection. Have ground checked first--then module. Guages probably okay.
