[SP_3.2]

Today with the Outside Temop at -3 the temp gauge was showing was a bit under the 80 mark, this was on the motorway at 70mph . Is this about right with the cold weather . Put the heating one from when i started the car.

When stopped at work the temp went upto 80 within about 30sec before i turned off the engine. Not sure if i need to replace the Stat  . The cabin temp seemed to be working fine.Also should the temp drop whenn heating is on in the car by much  when set at 24.:question and is there a way of checking the temp with Tech 2.

Thanks for the help

Steve.

dont know about tech2 Steve, but mine is about the same mate. I wouldnt worry. About the 3rd or 4th post ive seen on this in last couple of days. :-)

Thanks Chris.
Just dose not seem to move that much but then again in the summer it was a lot higher but was not using the heaters in the car much. I have not  been taking much intrest in it only over the past few days.
 
It dose seem to be a Hot Subject   . Don,t whan to have to strip the engin down if it is ok.

noticed my 2.2 takes a little longer to warm up in this cold weather.

Mums 3.0 was also just under 80 on a cruise in -1 temp. in town though it went back to 85

Out of interest what should the temp be for a 2.5 V6 mines always about 90* odd ?

This seems to be a really "HOT " topic at the moment with the weather getting a lot colder..mine takes several miles to get to 90 ish but after a steady drive settles at 92.5 and heater works fine,so just must be the cold moving air across engine keeping temp down.Yours sounds similar to most so expect all is fine.

Well i'm thinking that for where we live, we aint going to see temp ranges that the manufacturers havent accounted for. In uk im thinking the designs got to cover, to be safe, minus10 to plus 40 degrees maybe? (if you take the car to Spain for instance)   Yes it will take longer to warm up in winter and the fans will be flat out in extreme summer. So long as the needles showing on the gauge and its not over heating leave it be... imho.
Im sure the experts would agree along similar lines...

If your A/C or climate is on due to demisting, the fans are bound to send the cold air through faster causing a bit of a chill factor on the radiator :-/  

Maybe  :-/

what you are describing sound perfectly normal for this time of the year, mine is doing the same at at some points has gone so cold it has gone from LPG back to petrol.....

Wind chill is the key factor here......the mid may read -1 but the wind chill will be a lot more and that is that the rad is being exposed to, this is cooling the water and so the overall running temp is different.....
i have my vapouriser mounted under the wheelarch, was doing some set up last weekend, the engine temp was 85 degrees the vapouriser temp was 60 and tht was with the outside temp being 0 degrees
as soon as the car stopped the temp equalised because the wind chil was no longer an issue

i would be more worried about it running hotter than normal in this weather

My understanding is that the thermostat opens and shuts as required to keep the coolant in the engine at around 92.5°C.

Obviously at this time of year it will take longer to get to this temperature, 'cos it's starting from a lower temperature.

If it never gets to this (or close to this) temperature, then the thermostat must be allowing flow through the radiator when it shouldn't be.

  :-?

Edit:  However, this assumes that the dash gauge is telling the truth about the coolant temperature.  I imagine the gauge sender is an NTC thermistor, and these have a nasty habit of deteriorating in such a way that they 'read' a lower temperature than they should as they get on in years.
