Never mind about all these alarms - what about my new set of gnashers!!

Just to get off thread - I fitted the Mason alarm yesterday - seems funny to see the gauge actually doing something - but unfortunately there aren't any decent hill to test it on here, on the Somerset Levels!!

Mason Alarm- first thoughts after fitting.

The needle is quite active and sits at 1 oclock position and moves slightly about that point.

To calibrate the warning level I wound in down to 3 and as I drove I cranked it up very, very slowly until the warning stopped.

Next time it beeped I upped it a bit more until I have a no warning in normal use. Thats at 4 on the unit.

I havent slowly climbed a long hard hill yet but what I have noticed is that the max setting for a warning (ie the highest temp) occurs AFTER climbing a hill and then taking my foot off the accelerator and braking down hill. This produces an engine speed between idle and 1200 rpm with a slowish forward speed. Probably the water pump just idling with a poor cooling effect from the low forward speed. Accelerating the engine cancels the warning (high engine speed?).

Will report further.

I fitted mine tonight (quick service Dave

) Easy peasy to fit and ran around town tonight in L hold to get the engine hot.
Nothing sounded at 4 but as soon as I stopped and the temperature rose a little it alarmed. Now set a smigin' under 5.

Well, big trip to Scotland next week, 360 miles non stop. So for peace of mind went down to see Haydn and now have a coolant level alarm fitted. It's money well spend and could help you save a small fortune. Sure there are other alarms to consider, but I think this one is a good place to start.

As reported by me in http://www.igmaynard.co.uk/bongo/forum/ ... hp?t=13259 I have fitted the Mason alarm and am happy with it but I have also fitted a level switch in the header tank as a coolant loss alarm. It's not wired yet as although my first attempt worked OK and alarmed under test conditons I wired it into the key in/door open buzzer (which I had previously disconnected) and I didn't check it out during the dark hours - the alarm came on as soon as I turned my lights on

A little modification to the buzzer unit should sort that - when I get time.

Anyway - I think the more instrumentation the better but I still check the coolant level every journey.
