Unless you're including extreme weather in your 'range' there, that's absurd.

I can remember several summers where it hit +40 (summer of 2001 in particular was crazy). And we hit -40 several times a few years ago.

I just provided a temperature range of what can happen hear. Obviously, ever day is not -40 in the winter, and +40 in the summer. To make that assumption is a little absurd.

Adjusting for the humidex, yes. Otherwise, no. In fact, it's *never* hit 40C in London. A little Yahoo shows that the hottest temp on record for there is 38.2C And that was in 1988.


Does ambient humidity have a significant impact on a car's cooling?



No, we didn't.

Lowest temperature ever recorded: -31.7C. In 1970.



No, you didn't. Whether you mean to or not, you're misleading people.



When you fail to clarify what you're saying, what else are people going to think?


If anyone's still reading this, normal daytime temps around here are around 10F-30F in winter and 70F-90F in summer. There ya go.

Going by stored weather data is not always the most accurate, I hate to push this farther off course, but when temps are recorded in a large urban centre, the are always warmer than what the surrounding areas are..In Calgary the low temps were recorded as minus 33 ish range last week, and across the city there is always a 7 or 8 C spread in temps
Where I live just outside of Calgary , the temps were actually in the -41 to -43 range, depending on if you were in a low spot or not...
But arguing about how hot it really was and splitting hairs by a couple of degree c, reminds me of watching that movie grumpy old men...
As for the thermostat question, never run without a thermostat, as engine temperature falls, metal wear goes ahead exponentially, and not to mention, looking at how many other thermostats are in the the FC's motor, that are in there that were designed to work within a given tmeperature range and with each other, throw off one variable and the whole system goes to pot... When I first got my GX it had an overheating problem, on the highway, this I found to be the car had no thermostat whatsoever.. In heat transfer, the speed the substances are moving is part of the equation, move a fluid to fast and it picks up less heat.. Adding a 180 degree stant thermostat, took care of that problem..
And basically I have to echo what aaron was more or less getting at, we drive our cars in Canada at both of the extremes, with thermostats and have no problems running with them from the coldest of the cold to the hottest of the hot..If you a problem with the thermostat, replace it...Simple as that...

Aaron must be deliberately misleading you, since all official weather data is taken in his back yard...

Yes it does have an effect. Moist air cannot absorb as much heat as dry air, so the radiator's heat rejection rate is lower on humid days. Whether that effect is significant depends on how close you are to your cooling system's capacity.

SPI electric.
Be careful with those Cyberdyne gauges - those senders go bad very quickly.

I can't believe you guys are arguing about this still!
I already conceded that if you regularly see freezing temps (and below), it is not recommended to pull the thermostat out!

To Mr. beamer242, PM me for my mailing address.
I expect a brand new Mazda theromostat shipped to my door cause you offered.
I had stated before that I ran into an overheating problem at 2AM in the morning - there was no way I was going to get a Mazda OEM thermostat to "fix" the car at that point at night.
I never bothered to replace it since it hasn't given me any "problem" to this day.

I should have elaborated when I asked. My first aftermarket gauge was mechanical (Sunpro.) It, like yours, would report temps as low as 165F when highway cruising in winter and 170F in summer. I just accepted it. Then this year I install the Cyberdyne and the results changed. With the exception of the 176F a few nights ago, the temps, regardless of weather and driving circumstances, will not go below 178F. Something wasn't right somewhere with the mechanical Sunpro, and if you had replied that your own was mechanical I was going to enjoy having a Scooby-Doo style, "Ah ha!"


I didn't want to hear that.

RETed

Yeah, even with the cored thermostat, I can't get the temps under 180F on my SPI.
Even with the fan blasting at idle (least load on cooling system), after the engine has warmed up to temp, it will never come down under that.
Keep in mind this is Hawaii.

I'm not sure what that's supposed to mean, but it got this thread closed.
