Water alert sensor

G'day Brian
Haven't got one myself but Andrew from NT has one on his patrol, as he once lost a hose and dumped all his coolant and cooked it. I am told it goes off when your level goes down by about 2LT. So in my patrol with 12.5LT capacity it would be a good early warning device. Andrew says he is really happy with it.

I am pretty sure Roachi has one and somene else I think.

My step dad had one in his 75 series cruiser. It had a light and also a buzzer so you can not ignore it. It saved his engine once. It was an ex mine truck and came with the system.

Brian...just purchased one and I'm going to fit it this week.
Bought the one where you cut the hose.
So far have heard only good reports and I have also seen the other side where others have accidently cooked their motors.....so I believe it can be a benefit.
I have looked at all the other methods and this seems to me the best option.
cheers Phil

I have one installed. Along with my headlight reminder buzzer, it's the best thing since sliced bread. MIne has the sensor installed in the top hose.

Hey Brian,
Only just hooked one of these up the other day to my 2000TD prado. After seeing the damage done to a mates 2.8 hilux after failing a w/pump and dropping all its coolant, it can only be good to have even if it never gets used. The model i fitted was the under the hose unit.

The thing most people don't realize is that once your coolant sensor is not immersed in coolant it will read normal or drop as it can't read steam. Hope this helps cheers Ben

Well if it saves an engine its WELL worth it I dare say, cause murphy's laws would indicate it want happen in a town, but out in the middle of nowhere. Basiclly no engine .. no power .. no beer :( be a critial problem to say the least.

Seems like I will get one just to be on the safe side.

Thanks for the replies.

I have one and will be fitting one to another vehicle I have soon as I buy it.
Hardest job fitting was finding a suitable earth connection around all the plastic under the dash.

I have never seen a vehicle temp gauge that would alert you when you rapidly loose water or boil the radiator. Drivers just don't notice till it's often to late. You can test your low water alarm by draining a little water from the radiator. Perhaps do a test every time you do an oil change.

I was on a club trip recently were several 4wd's went through a bog hole where the water/mud was the consistency of a thick shake. Two vehicles got blocked radiators and boiled but the drivers were not aware of it till they could smell the overheated engines. When they had cooled enough we opened the radiators and by the amount of water used to top them up they must have been almost dry. Took all day to remove the radiator(s) out of the Paj and using fine wire clean all the rootlets and baked mud out of the Oil cooler radiator, Air con radiator, Engine radiator, Transmission radiator.

Like all others who have one , yes it works and is a good investment ,

Yep, got one installed in the Patrol and it works well. Only put it on after nearly cooking it down near Tamworth last year, shouldn't have that prob again. Don't forget to test it regularly.

About to order one online - they have 2 optiomns:

in-line
and
under hose

Interested in your thoiughts on which one you chose and why?

I bought and fitted one to the Humvee recently and it works well, with a warning tone and LED self test when starting the engine each time.
They supplied a probe with a 1/4 " pipe thread which I screwed into a tapped hole in the side of the coolant reservoir. I only have to lose a litre of coolant before it goes off, hopefully never in 'anger'.
I nearly lost an cruiser engine years ago due to the drain bung falling out after a service and there was absolutely no indication of anything amiss till the engine was losing power and blowing heaps of smoke.
cheap insurance!
