Coolant Temp and Low alarm

**Lemo** · 22nd January 2018, 02:23 PM

Hi all,

Doing some research into temp and low coolant alarms.
Didn't want to over spend on a Madman EMS as I don't need all that these offer, just want low coolant and temp.

So was looking at this Haydn Coolant Alarms - Low Coolant/TM-2 Combination Alarm - (Powered by CubeCart) combined unit. Around $330 delivered from UK

Any other offerings from Aust??

Cheers Lemo

If you have the TD5, you'll need the top radiator hose sensor as well!

No I have the aulro engine saver version as listed in Dave's Shop and separate transmission oil and engine coolant temp gauges.
Quite like the idea/simplicity of your link, but suspect you can get the same effect cheaper - as per onebob's link?

I do... i have the low coolant alarm installed as well. It was the first mod i did to my D2 when I bought her 7 years ago

Purchased the low coolant alarm in the marketplace section on this forum

Yeah looked at these, same unit as supplied from the UK so Id say they get them from Watchdog in Aust and install the low coolant sensor in them.

Might give them a call and see if they do the same??

Decided to go with the Watchdog TM1 and a low coolant from Dave's Shop works out to be the same price!!

Keep the money in Australia

Now I can't afford both at the moment so low coolant first??

Low coolant FIRST

It was a detailed discussion some time ago where i sustained my case that IMO a coolant temp gauge/alarm is more important than a low coolant alarm cos if there is coolant loss the temperature will rise as well but there can be many cases of overheating without the coolant to drop(happened to me) ... that's quite common and in this case the low coolant alarm is useless cos you can drive it for long at 115*C coolant temp without even knowing it as the factory gauge climbs from the middle only at 120*C...and that's not ''healthy'' for the engine... i've had a coolant loss once at the oil cooler and i observed while driving that the ECT grew with 5*C from normal without forceing the engine so i stopped and saw the problem... so IMO coolant temp first all the time
