warning system

Mik you cant take the radiator cap off every few miles. A blown hose or similar will result in a melted motor before you know it.

I think they are one of the best investments you can make for your car.

Some late model stuff may already be fitted with low water level sensors.

there are a number of units availaible, when you use staionary engines that are un attended(water pumps, gen-sets etc.) you always fit this sort of gear to alarm then shut down the motor if levels drops:-fuel, water, oil, oil pressure, exhaust temp safety as well cyclinder head temperature. Jeep turbo diesels and a lot of european cars & trucks have systems fitted as "Standard", makes you think about what your car maker left off to protect your investment.

Adrian stop shouting. Upper case is defined as shouting use lower case,

It also makes it hard to read !

Sorry Mik, a correct temp guage WONT tell you youve lost all your water.
The first you will know about it is when your motor stops.
A temp guage doesnt tell the temperature of air.
An oil temp guage may help but I beleive a low water sensor is a better investment.
Especialy in a 4wd where a stick can poke through a radiator or rip a hose without you knowing.
A radiator (especialy an alloy one) can crack easily from hitting a pothole or similar too hard.
And I have even seen a welsch plug blown clean out of a block for no apparrent reason.

I think you will find that most motor failures are through being 'cooked', and when you 'cook' a motor you usualy have to throw it away.

I agree with Simon,
You can't rely on the dash temp sensor in some cars as they don't read if not imersed in water.
One guy said when he cooked his Landcruiser from a burst hose the temp gauge didn't move at all from its normal position.

I have fitted a low level sensor to avoid such problems and test it now and then by removing the wire on the sensor (open circuit).

Cheap insurance !

A lot of holden V8's have been cooked before the temp gauge had time to register high temp after a loss of water from radiator. This is especially true when motor started from cold!! Richard

Sorry Blew that one.
I fitted an AQUA ALERT. Cost $99 and it comes with light and alarm.
I found it great and would assist should water be dumped from the radiator if staked by something and guages don't pick it up in time.

Kev, where did you buy it from and how did you go about fitting it and where exactly was it fitted?
