For the record,
and for Haydn's info, his Mk 1 alarm saved my bacon by
sounding when the coolant level suddenly dropped
today - and his TM-2 engine
temperature monitor confirmed that the loss was
not at that stage related to
overheating. There's some evidence of (dried)
coolant spill around the
radiator cap - whether newly deposited or not I
can't tell, but I'll try a
new cap first, anyway. Can't see leak signs
elsewhere but will get a
pressure test if the cap doesn't do the trick.

we had our new hoses fitted and Hayden's alarm about 2 weeks ago,
all was well kept checking coolant.
We had a rushed visit to
hospital last night 70 mile round trip. I got back 4am this morning
leaving Gary there.
(we should be camping tomorrow) anyway we got
in bongo this morning to go back to hospital and the alarm sounded,
put the bonnet up and to my disbelieve no visible water in the tank.
I put 1.5 litres of water in and took
it to the garage who
fitted the hoses and alarm, he had a good look and could find
nothing said it was ok to do
the trip again so I did got back all
seems fine. I have not checked the tank yet as it's too hot, but
will do later,
What do you think air in the system that's found
it's way out? I hope so.
The moral of the story is if we did not
have the alarm I would have defo cooked the engine today so
so much Haydn.
Many thanks for your quick
(understatement) response in suppling the MK1 alarm. It arrived
on Saturday as promised. I had to delay a drive out for family
commitment waiting for the postman but was able to install it
this morning - an easy way to spend an hour or so on a Sunday
morning. The clear and simple instructions made the job as
straight forward as others have reported on the Bongofury forum.
More than delighted with my
alarm, even managed to fit it myself it's that easy.
It has possibly saved me a
fortune already, as when I had leak in the radiator, the
alarm went off, letting me know that the coolant was low.
therefore catching it early. If I did not have the alarm
fitted, I dread to think what could of happened. I would
recommend fitting it as standard.

About a month ago I
had the hose that leads from the cylinder head to the heater matrix pipes
split, the coolant alarm picked this up fantastically well; there was still
coolant left in the header tank when I pulled over to check why the alarm was
sounding whilst I was on the move (never heard it other than at start up
before). Was able to wrap the hose well enough to get the mile or so home.
New hose fitted and problem sorted No overheating and all the horrors
that go with thatAll the usual riders about my cooling system being known to
be in a very poor state of repair apply (although at this rate it will
probably be all shiny and new inside the year!), so your mileage may vary! I
know a lot of you guys out there really aren't convinced by this but I already
think the alarm has already saved me from another engine rebuild!
I fitted the Hi
Coolant Alarm add-on at the weekend & it went very smoothly. It took just
under an hour, but only because I had to remove the instrument panel / speedo
as I'd previously fitted the Low Coolant alarm behind the circuit board so I
could mount the LED above the temperature gauge. In addition, I had to remove
the cowl around the steering wheel as the cruise control stalk was getting in
the way of the speedo removal.
The only modification required was to fit a solder ring tag to the red
positive wire so I could take a feed from the back of the instrument panel.
That was just 'cos I wanted to match how I'd wired the original alarm.
Testing the unit was easy: dip the spade connector into the top of the
expansion tank & after about 5 seconds the alarm starts to gently sound & then
build to full volume after a couple of seconds.
Haydn, I'm very impressed with your addition to the Low Coolant Alarm. It now
covers the scenario I had when my head gasket failed, as well as when I had a
airlock due to a pin-hole in the bleed hose. Nice one
