TM2 engine watchdog

Hi
I've just got my TM2 from Aus. and I know others have one fitted. What's the concensus on where best to put the sensor, and what temperatures do you set your gauge at? Looks a simple fit, but did anyone drill through the engine case to fit the sensor? Did everyone fit the oil sender option?
Cheers
Helen

check the last page here:-
Gauge

It shows where I fitted my probe

from a simple thermometer. (don't know if this is the best place) Normally reads are around 100 deg, going up to 115-119 deg when the engines working hard

Thanks, Brora, that's about where i planned to put mine, but I'll drill a hole inthe engine casing (seat base) to put the wire through, as I'm sure to b****r up my wire connection to the sensor , lifting the seats up and down. My alarm "thingy" also has a connection for the oil pressure light sender....any idea where it is...I just looked, and my bongo is always parked in the shade, and i always manage to forget a lamp!!!!!

if you connect it up to the oil sensor it is a constant very annoying beep until the engine is started,
i never bothered

Brown/white wire that exits a small white plastic plug/socket at the top /back of the alternator under the drivers/passengers/any seat you wish

somewhere in the general vicinity of the bongo

Hi Clogger
Many thanks, I'll probably try it and do as you have, and disconnect it if it's that bad!!!Isn't the alternator on the passenger's side?

I put a switch in my oil alarm wire so I can turn it off till the engine is started. You never know it may go off one day and perhaps not notice the oil light. Mind you I expect by the time it goes off it would be damage done.

I've fitted mine in the little "cubby" hole in my BMW clock. Perfect fit.

Ahh
I've mounted mine in the BMW clock cubby, but whereabouts did you bolt the temperature sensor....I'd be interested in your various readings , folks.

the good old turbo timer lives in the bmw clock cubby hole and claimed squatters rights

i have the sensor mounted passenger side of the engine 2nd pre drilled/tapped hole down on the actual cylinder head

summer readings were up to 110c
cooler weather on the same stretch where it normally reaches 110c
last week it was 98c

Hi Cloger
I've fitted mine under the 1st. rocker cover bolt on passenger side. It reads around 40 - 50 on a run, and 75 in a traffic queue (not frequent here). I suspect there is a cooling draught coming up from air passing the belly mounted fan assembly, keeping the reading low.

I begin to wonder how one turns this device into a reliable engine protector. Do you wait for the first head warping event then set the potentiometer (or whatever) to slightly below that temperature ready for next time

Seriously though - can anyone enlighten me

Gotta say though, the low coolant alarm is a no brainer and is a major cause of my relaxed attitude to life these days - better than Prozac.
