Re: Temperature Guage at 70 when warm!
Just had my thermostat replaced and it seems to have solved both problems of running cold and over heating in traffic.
My car used to run at about 60 degrees, sometimes less, but would creep up to 110 in traffic. Since the thermostat was replaced which was a reasonable £22 from Car Spares (part no QQTFTS331.88), it gets quickly up to 90, then the thermostat opens and it drops down a bit and then sits just below 90. Even in traffic it seems to go just over 90.
The thermostats are marked with 88 degrees on the housing, so it would seem that they open and close letting a blast of cool radiator water into the system. As the car runs at around that temperature it must open and close depending what type of driving you are doing, helping to keep the temp down as well as keeping it up.
I bought my own coolant (5 year long life good stuff) and thermostat and a local garage changed it for me for £35. Total price £78.
I have lived with this temperature problem for about a year, but should have got it changed sooner. Its worth it.
I'm now going to see if it makes any differnce to my mpg.
One thing of interest... the box with the stat in, as well as being for a 156 up to 2002 was also marked Fiat Punto 96-02.
