Those of you who saw my other thread will all know, I had a bit of overheating trouble due to a little hose that i stupidly left the clips off! Since then I've had no overheating issues and regular checks have confirmed that I'm not loosing any water!
As I was loosing a lot before i am just running water without antifreeze so I plan to drain it and change it soon adding 50% antifreeze. I believe the Altezza needs the red stuff so is this suitable (as I get good discount on it from local factor)
I have had a new weird issue for the last week where the temperature gauge on the dash is displaying the water temperature as not getting up to temperature for ages!!! It used to be that it would be up to normal (very slightly under half way) about half way to work and driving for about 15mins but now I can get all the way to work and still only be on a quarter! It will never overheat or go above the normal level still but it will take a good long time and few journeys without cooling in between or long idling after a journey etc to get it there! I might be just imagining it but the car seems to maybe be idling a bit higher at traffic lights on way to work (about 25mins into journey) at 1000-1100rpm rather than usual 900ish too.
The way I see it, there are three possible options:
> Gauge is faulty
> Temperature sensor or sender for the gauge is faulty (is this in the rad btw?)
> Thermostat issue (though would this affect the heater from getting hot if so cos I think that is ok?)
How can I test any of these accurately and can I use the info from Torque to help in any way? What other suggestions have people got please and advice on how to test any of it please?
I plan to change the water and see if that makes any difference but I can't see it will as it seemed to be reading accuratelt before and Ive been running it on just water for few months while i had the leak issues.
