Engine Watchdog

Has anyone installed this or a similiar product .."Engine block and head temp alarm/engine watchdog TM2.."
I have been looking at these on evilbay and am wondering if they are a good thing or nay ..any advice appreciated ..
cheers Tezza

Tezza mate, I got one of these, every vehicle should have one IMO. It's way superior to the standard temperature gauge, it reacts very quick to warn you if things are getting too hot, you can set it to alarm at any temperature so you will never cook your engine if a problem arises. I installed the probe lug under a spare bolt on the intake manifold on the head.

Thanks for your reply ..just confirms my thoughts on them so now I will order one in ..

There was a Murphy switch that was on a few trucks, little problem was if you went around a corner too quick the alarm went off and lights flashed It had a sensor in the top of the rad.

Good idea tho.Never thought of them for cars.

I can get similar product with digital read out with loud piezo buzzer alarm
you can set the alarm at any temp from minus 50C to + 1300C
also has relay out put for switching on a/c thermo fan at any desired temp
I have one in my van and they work a treat and only half the cost of the engine watch dog about $70.00
very easy to install ,all power is from accessory wire and uses factory relay to activate the fan and keeps all factory thermo switch settings.
I set my one so fan comes on at 90C & off at 85C and alarm set at 99C
you can set it to any temperature you want.
anyone interested let me know

Howdy Mr Freeze,

Yep very interested the one you describe has a lot more scope than the Engine Watchdog.

Where can I get one

Cheers Dave

Hi Dave,
I only have one left, I actually imported a few of them from China just for a test run to see if they were popular or not.
I add the piezo alarm my self
Been selling them to friends and word of mouth.
if you want one let me know your email address and i'll send pic of my one and you can decide.
I can show you how to wire it up as well.
Cheers Tony

Hi Tony
Me again...I've just spent nearly 3 grand on a new head etc for my 3L and am still having overheating/waterloss problems
I suspect the head gasket not installed correctly (the water system is pressurising)
Any way, once I have the problem solved I want to install this device you speak of
I can't find anything in NZ through he usual car type shops
I'm stuck with a vanless Christmas till the garage opens up
Boo!
Gutted!
Any help appreciated!
Cheers Bruce
