my puma was running too cold on the analogue dial (R Reg) so i had the thermostat changed. Since this has been done the dial sits a little higher on the N or O of normal on the gauge.
my question is, is this normal? i read on the WIKI that some say it should sit bolt up right in the middle and some say it should sit on the N? which is correct?
if its supposed to be in the middle, what else can i do to see whats wrong after changing the thermostat?
Maybe you replaced it with a thermo that opens too early? that can be the issue.
Have you monitored it on highway runs? Both at 75mph runs and 100mph runs?
I give you the example with my ford Orion. Precisely same issue as yours. Changed thermo, changed everything I could from the cooling system. And is just like that. Also, I suppose the digital dash cars sit higher than analog ones, but i can be wrong.
