ENGINE SAVER NEW LAND ROVER KITS

Hi Davy,
I just replaced my plastic Bungs on motor and radiator with brass units and am enquiring re this new sensor as it is still using the plastic Bung is this the factory plug modifide or a new design that will not brake as i had happen.
I know if it did brake it would worn me that i am loosing water but just checking as I have been lucky twice now 1-Radiator (replaced with 4 core)
2- top of plastic bong in thermo housing cracked and started loosing water in drive way.(new Brass bungs).
so was thinking I need an alarm for low water.
Cheers Allan.

Hi Alan

Very good question & one I have been asked a few times in the past week.

Before we designed our screw in sensors we did some serious research
into the properties of plastics when exposed to liquid coolants and high temperatures.


The original plastic plugs are injection moulded from straight nylon with a half life expectancy of 5 to 7 years at normal engine temperatures
( this is the point at which the material degrades to 50% of it's original strength)
A temperature event at any time in the vehicles life will dramatically shorten this life span

Engine Saver sensors are machined from solid Ertalon 66GF30 material.
And have the solid stainless steel sensor core through the centre.

This is the stuff most modern high temperature engine components are made from.
Rocker covers, water pump housings, inlet manifolds and accoustic covers are all made from this material.

Our In-Line sensors are also made from it and have been for years.

In short it has a far higher working temperature and service life than nylon and should easily outlast the vehicle.
Continuous working temperature ratings are 120 degrees for 5000 hours or 110 degrees for 20000 hours

Straight nylon is rated at 80 degrees for 20000 hours

Incidentally the bleed plugs in the Series 11 V8 and the Defender Puma transit engine are now made from this new material as well.

When the older vehicles were made this material wasn't generally available.

Another place straight nylon has been used is in the white drain plugs in the bottom of the fuel filters.
I had a customer last year tell me his had failed and the fuel had leaked away...

I hope this has been helpful

Hi Davy,

I like the look of this product, although it may be too late. I have been losing small amounts of coolant for a while now, although everything else seems okay. If I ignore the problem it might go away:p.

At least your device will remind me to top up the coolant when the level falls too far. I hope you have a kit for a D2V8 in stock as you'll be hearing from me soon:cool:.

Cheers,
Alan

Dont ignore it Alan;)
mine lost little bits so a nice Mechanic friend stuck a jar of black stuff in the radiator,,
fixed! for almost 2 years now,,

The D2's can leak and not interfere with cylinders,,
The D2's can leak and it not be a slipped liner,,
The D2's can leak and it not be the end of the world.



Though of course, sometimes it IS the end of the world----

Please excuse my ignorance but what do these little things actually do/measure.

Aussie;

The Engine Saver Sensor "alarms" the driver if there is any loss of coolant due to a Blown head gasket or damaged Radiator hose , etc , etc , if there is a "leak" in the cooling system due to whatvever reason it allows the driver to take appropriate action to save the engine from being distroyed or heads getting cracked etc.

In my not so infinite wisdom I decided to tap a thread in a brass plug and screw the stainless sensor in to that :angel:

Will this still read correctly or do I need to buy another plastic one off you? :oops2:

Thanks

Jock

If you screwed a fully insulated sensor into the brass plug, yes it will work.
However if you simply drilled and tapped the brass plug and screwed in a metal sensor, no it won't work as all you have done is earth the Engine Saver electronics directly and not via the coolant level.
You can verify this as you will not get the test beep & led flash when turning the ignition on as the unit self tests.

If you need a complete sensor let me know.

That makes sense, but I still get the test beep and LED flash? :p

I have been meaning to drain some coolant out sometime to see what happens

I would have thought the sensor would still work (with the sensor screwed directly into a brass bush) providing the fitting, the brass bush was inserted into, was insulated.
This would probably, however, affect the tolerances of the sensor causing it not to work as well as originally designed.
Could be wrong but!:D;)
