    Aftermarket temperature alarms

    Hi all.

    Has anyone fitted an aftermarket temperature alarm to their vehicles? I am considering fitting something to mine after recent events. Just another little driver aid so that I can spend a bit more time looking at the road and less time being paranoid about the gauge.

    Something like this:

    TEMPERATURE GAUGE & ALARM Detects Low Water / Coolant Relay Cooling Control EG3

    Obviously there are a lot of different designs including the traditional round 52mm type as well with the sender inline in the coolant.

    Personally I prefer having a low coolant alarm, it should give a warning something is wrong before overheating starts.
    I fitted a sender in the expansion tank and put flashing leds on the dash. Cost about $10

    yeah here's the thing with all the cheap float switches on ebay, they generaly only say upto deg 60-80c in the case of the one you list 80c. but cant coolant go upto 100 at least or a above (as under pressure it can) ?

    The sender has been in my car for a year with no problems, I use the car every day. They are $2 each so if one craps itself you dont need a mortgage for a new one!. If you read the thread I put the link to it also shows how to fit a BMW unit. You can also get a complete BMW header tank which is almost identical with the sender fitted.
    You pay`s your money and you take your pick!
