Fitted a
mason alarm over the weekend,I expected a rise in temperature reading after reading a few threads on the matter however mines only moved slightly!it was at the 11 o clock before and now half way between that and 12 o clock. I also had to move the
alarm setting from 4 to just below(approx 3.

which seems to be right for the normal running temp. Is this normal? Or is my coolant system top notch!?
Noticed a difference when I had 8 men in it going up a hill!the temp rose a little bit and the
alarm went off briefly but that's about it!
