I have recently bought a 2.0 petrol  56 S-Max which i love. My question is can any owners please tell me whereabouts on the temp gauge should the needle be on normal running?  What is the temp for the other lines? Please see attached photo which is after sitting in slow traffic for a few minutes. Never seems to go over this position and overheat

Thing is it only gets to there when stuck in traffic and goes no further than this. It usually sits on the line up from the 60 and this is when driving say on the motorway

Hi Gary,

 

When your moving your getting the air cool affect on the radiator, when your sat in traffic idling, you dont have this luxury which is why its running hotter. However, anything up to about 105 degrees is normal, if it stays there most the time in slow moving traffic then its normal, anything less than that (between 60 - 100) is a very good place to be.

Hi James

Thanks for getting back to me. You know what its like when you buy a new car you listen to every little noise and study the temp gauge. As stated the needle in photo is the highest it gets and that was taken today when 20 degrees outside and stuck in traffic. Usually going down the motorway to work it sits around the second white line. What is the line after the 60 temperature wise? I guess the one at the 6 o'clock position is 90?

they are 15 degrees incriments, so you go 60, 75, 90, 105, 120 :)

So my car is running at 75 under normal conditions and raises to 90 when in traffic. So you think i have nothing to worry about and no need to change thermostat? Thanks

I personally think its running fine.

 

thermostat replacement would only be necessary if the fan is always on like a wind turbine, or if the temperature goes up and down like a rollercoaster for little reason.

 

If you want to be cautious, then you can check the coolant expansion tank cap is not cracked or damaged, but I suspect you have absolutely nothing to worry about. If you bought the car from a garage, you will be entitled to 6 months warranty, so if anything is wrong, they will be obligated to fix it.

Only other reading is when needle is a cats whisker under 75 but that is only if AC is on and on cold setting.

 

 

Think i will take your advice as i have a feeling you know what you are talking about :-)

Air con does reduce the temperature a little as the compressor is operating and the liquid refrigerant takes some of the heat out.

 

I certainly wouldnt worry about it at all :)

also once you had a run in it,do the on board diagnostic check.scroll through the menus and see what the actuall temp of the car is.

if you have the trip computer, turn the ignition off, press and hold the reset button as you start the car, keep hold of reset (it will reset your trip odo) then the car will enter TEST mode, let go of reset. then you can press the reset button to circulate through each of the options, and you can find the temperature in there - thats the real temperature rather than the rough guide on the gauge.

Its normally the reverse of this - the heat that is taken out of the AC system has to be dissapated ( its a heat exchanger

  the cabin gets colder, the heat that is sucked out has to go somewhere) it is normally dumped in front of the engine radiator, raising the engine temp, not reducing it, thats why the fan comes on when the AC is switched on

 

Modern cars may run cooler due to emmisions/ economy - deisels normally run hotter  than petrol-engined cars, on both, there is an optimum temperature for economy, and optimum temp for emmisions, and an optimum temp for performance, the running temp is often  compromise between this, though emmisions/ economy are high priorities these days

 

To give you and example, some  truck owners were fitting special thermostats to their diesel trucks to get better economy, at the expense of some performance
