I've been quoting my old gauge form my old car
Sorry.
The gauge reads
N
O
R
M
And at the moment it never goes above the M
A lot of the time its under the M
Well, in that case you need one of these

that's the second one 2day
Oh, and now that is cleared up, ignore my post about the thermostat, if its running at normal temps, can't be that....
Keep an eye on it
