    Engine Watchdog Tm2

    Anybody on here using one of these TM2's?

    Link: http://www.sig.itel.net/

    If so are they any good?

    I like the idea of surface temperature monitoring (say engine block) after cooking a car engine when I was younger. As you will be aware the temperature gauge can go down on some cars when the coolant is lost!!

    I put the extra temp sensor for my rig in one of the bolt holes for the hook at the back of the head. That way it uses the head temp and not the coolant temp.

    A copy of what I posted in the other thread.....

    I bought and installed one of the Watchdogs.

    I bought it mainly as insurance after fitting thermo fans. Just incase they fail while I am too busy to be watching the temp. In this scenario, a low coolant level alarm would be pointless.

    I have a three way switch for the thermo's, 1) Temperature controlled, 2) Permanently ON, and 3) Permanently OFF (for water crossings). On about 4 occasions now, the switch has been bumped while offroad, and switched to the OFF position (I know, I should probably move it). The Watchdog alarm went off each time to warn me WELL before any damage could be done. The alternative could be rather expensive.

    I did the same as George130.....bolted it onto the back of one of the heads.

    Cheers

    Thumbs up

    I have got one in my Landcruiser with the temp sensor located under one of the thermostat bolts, one in my boat measuring head temp and one in my jetski(measuring oil temp).

    I loved these things so much, my friends started getting me to buy them, so I did a deal for them on a forum and organised a special price including free overnight delivery anywhere in Australia...

    I think they are the best thing - they give you an ALARM for a start, secondly, Most OEM Temp gauges in our cars have a huge deadspot so they don't start moving until the temp is high enough that it is often too late before you notice the gauge move and thirdly, you can see the exact temp, measure it from what ever point you want on the engine also...

    Thirdly, It's a damn low cost way of having a better safety net if something in your cooling system is failing or on it's way out!

    If you guys are intererested, you can get the same deal by clicking on this link: TM-2 Engine Watchdog With Settable ALARM at FULL WAVE MARINE

    Anybody like to offer a suggestion as to where "Full wave marine" may reside,

    I don't like dealing with companies that don't have any contact details on their web sites - no address, PO box, telephone, - nothing that I could see.

    To me suggests WARNING WARNING.

    Hi Martyn,

    Full Wave Marine is based in Brisbane.

    I operate it from home as it is not my full time job and it keeps my costs down to offer low prices... mostly to friends - it's not exactly a big business with any staff - more of a hobby thing that a friend of mine and I do in our spare time... ie. these tm-2's were only put up there on that site for friends who wanted them on another forum for their 4wd's so I organised a group buy for them.

    If you want to know me you can go on offroad80s.com and look at the threads there - everyone in general gets them overnight - they are sent by Australia Post Express post - you are protected by paypal also.

    You can email me and I can give you my details over the phone if you are concerned?

    Regards,

    Frank

    Hi Pheonix,

    They are extremely acurate.

    The idea is that you set the audbile and visual alarm to be a couple of degree's higher than the hotest temp that it measures normaly to give you a warning when it starts to get hotter than normal - so that you get an audible and visual alert way before it's too late. Most OEM temp gauges are not linear - ie. there is a deadspot by design to stop people worrying about the temperature large fluctuations - problem is that when something goes wrong - like a fan clutch on it's way out, by the time it goes and them temp gauge shows it (if the person is looking at the time) it ca often be too late. By having an alarm go off as soon as it is say 3 degree's above the mornal hottest temp - you have plenty of warning before cooking anything.

    For your information - I have tested them against a commercial quality IR gun and they give the exact same reading as each other.

    IR Guns are used to verify factory OEM gauge sensors as per a lot of FSM's these days
