I wouldn't bother keeping an eye on the temp gauge dobby, if you re-fit (i would) the mason alarm, the alarm will sound if the needle exceeds the limit which you have set via the adjuster on the front of the alarm.
I'd set it at 4 for now, then tweak it subsequently to suit your vehicle/conditions.

Good idea BDC, it's going back on this weekend.
By the way, if you set yours to 4 what position does the needle normally stay at assuming a scale of 10o/c to 2o/c?

err, i've lost the instructions. Got the fact sheet but not the wiring instructions is it as per this

as per this thread?

Thanks!

All the mason alarm seemed to do was woosh the needle further over to the right, then moved a bit more when then engine was working hard up and down the M6 etc.

Is it just me being a bit dim, but isn't that part of the reason for fitting the Mason alarm? It makes the standard gauge more sensitive (as a temperature gauge should be), so that you can actually see when it is getting hot & react to it, it doesn't actually make it run hotter.
It's a no brainer - get it fitted, don't really understand why it was removed, if you were losing coolant, surely you'd want to know if it was overheating?
Wiring all sorted now and alarm back on.
Miss Fixit70- I'm aware of what the mason does, I think the problem was that I fitted it to a system that was running hot and hence didn't see the benefit of it. Now refitted to a normal cooling system and I can see the benefit of it, i.e. you need to be confident that you are fitting it to a system in good order etc and then use it to monitor
Thanks all

On average, no strain running, i'd say a tad past 1 o clock. Nearer 2 o clock on the motorway, and a bit higher on a long incline... Consequently,a little lower on a descent.
I was stuck in some really heavy (over an hour almost stationary) traffic the other day,over time the guage crept to 5-6 mm short of the red, then the fans kicked in, (i heard, and felt them) Then the guage dropped to exactly 12 o clock within 30 seconds,then back up...and so on...

Thanks BDC, I tested it out today - set it to 4, did a few junctions on the M6 etc and it sat sensibly at 1 o/c ish - now back as a mason alarm advocate!
