Check the heat gauge sending unit. Or "engine coolant temperature sensor" as they call them these days. ECT. It should be somewhere near your thermostat housing. I hope that's the problem. Good luck.

My temperatur gauge shows hot when i turn on the ignition and two fans turns on right away can you tell me whats the prablem is?


Well it can be one of too things the gage or the temp sensor.
its most likely the sensor. The temp sensor is normally mounted with the thermostat housing which is on the top of the engine and has the top radiator hose going to it if you can't see it, try taking off the plastic covers. With the ignition on so all gages are reading go and unplug the sensor the gage should drop back strata way, this tells you that you have the wright sensor there are sometimes 2 one for the gage and the other for cold starting. There is a possibility that the problem may be coursed by a squashed or rubbed throw wire so if you can't make the gage return to cold by disconnecting the wires then start following the wires back along the engine.
I think you will find a faulty sensor is the cores of your problems and should be easy to pick up at any car part place.

Overheating gage when stop & go -2004 chevy tahoe


natural for engine temp to rise in Traffic - Until Themostat opens ) cooling fan sensor kicks on fan . But Antifreeze is not just a Cold weather item . Coolant is Absolutely Necessary for Hot Days . You must be full to recovery bottle setting of cold when checked prior to start up . Coolant for your make / model is Reddish - Pink colour and should have a reading of -25 thats negative 25 degrees the Lower the Better even - 50 .. Why ?? - 50 is 50 %% antifreeze / Coolant Concentrate MIX Gives Hot weather cooling Ability or very cold weather starting / winter HEAT .

Engine cooling fan will not opperate


check that you have a thermal switch to switch on the fan and not a temp sender unit. One completes the curcuit when a set temp is reached ,the other is a resistance unit that lowers the voltage which in turn reads hotter on the gauge.

Also could be cooling fans. Did you notice if your fans are working when it is hot? Could be bad fan relay which would keep your fans from turning.

TEMPEATURE GAGE READS HOT WHEN AT AN IDOL BUT MOTOR


If cooling fan works, it maybe a sticking thermostat not opening fully. Check that cooling system is full (check cold) first. Then if that seems ok, i would replace the thermostat.

2005 Pontiac Montana SV6 heater blows cold when slowing to idle


How cold is it there and does your engine cool down any while going slow? If it does it may mean you need a hotter thermostat installed, My first thought would be to check the coolant level in the radiator and the coolant reservoir! Hope this helps and Merry Christmas
