Been asked before I know

Hi Val, I have seen this one before but there is another one where a probe or some thing like that goes into the top radiator hose as well which also detects if you say burst a hose and all the water goes it will detect it instantly before you lose the lot where as the watchdog says it detects it BUT only once the engine starts to get too hot by then could be too late to shut it down and save the motor/head. I know 100% it has been mentioned on here before but for the life of me cant remember the name of it. Will do another google search and see if I can come up with it. Thankyou very much for the reply. Regards Steve M

I'm pretty sure this is the one http://www.enginesaver.com.au/ but it doesnt say about temperature settings only about coolant loss, I would prefer both, I have sent an email off to them so will wait for a relpy, maybe I will have to get both, one for coolant loss the other to keep an eye on temps. Regards Steve M

Here's another (slightly less expensive) version of the 'watchdog' >>

Engine Guardian

:)

Now some one has mentioned a concern that a probe having dc current to it could cause electrolysis ???? Bloody hell now I dont know if Im gong to be playing it safe or causing more problems later on lol ?? Anyone know or is it a mith ?? Regards Stve M

My enginesaver has been in for over 2 years and nothing bad has happened.


Well worthwhile and easy to fit.

The temp probe is attached to the head

If you look in my profile there is a pic of it

This is the kit for mine, doesnt bolt to the head. is purely an alarm for low coolant not for temperature , that is probably something else I would need to add as well, like the one Val has mentioned

To install I cut top radiator hose rougly in half, install the sensor clamp on either end and do the wiring, I dont need the two rubber stops as shown in picture, this kit is for a few different types of vehicles. Not sure on cutting hose (more places to leak ??) but for my vehicle is the only way. There are other kits where they remove say a bleeder valve and the sensor screws in but I dont have that option, I think the patrol suits the other kit must have a bleeder valve some where on it, looks like there isnt one that does both, level and temp that suits my vehicle. As above there is one that bolts to a bolt on I think the thermostat/head but have heard these take way to long to detect say a blown hose where it would dump the water so quickly and by the time it detected it the alloy head would be gone, might I say this is only what I have just been reading on different web pages. Regards Steve M

Hey Graham just checked out your pics, you have both, coolant level and the bolt on the head, is this two different units or all the one, this is exactly what I'm after. I noticed you have cut your hose to put the level probe in ?? Any issues Regards Steve M

Hi Steve,
It comes with both. No problems at all.
A great produce and excellent back up service.
I've had mine for only on 4 months now I researched and read heaps on a couple of the Low Coolant and temp alarms and choose The Engine Saver, I know It's a little more expensive that other units, but I choose it for reputation and back up service. I also choose the unit with the dial to set the temp alarm instead of the digital read out. I have found it easy to just adjust the knob rather than pushing buttons the set the temp.
Cheers.

Got mine off him before he incorporated them into one.


No probs just my temp screen chews batteries but the new model doesnt.

Just cut the hose and use the double ended connector as above

MIne has never leaked All good.

I bolted the temp sender on the head between Cylinder 3 & 4.Temp Sender Position
Amazing how sensitive they are.

Sorry link didn't work, this one should.
Temp sender

G'day Allan,

I agree with everything you've said, BUT I think you'll find the owner's name is David Jones (not Cahill).

I too have been using this product for many many years and have NEVER had any issues with electrolysis. As I understand it, you are only going to have issues of that nature if your wiring is "wrong" and the radiator is being used as an earthing point within the electrical system of the vehicle.

David is always working out new and better ways of getting the probe/sensor to interact with various engines. He recently developed a new sensor for the Chev 6.5 V8 which utilises a bleed bung point instead of needing to cut the top radiator hose.

Great product and I highly recommend (usual disclaimer).

Hi Roachie, Of course you are correct...... it's Jones, not Cahill. Where on earth did I get "Cahill" from?

I have seen some writings on this radiator electrolysis that are not just wrong but plain deceptive. In particular a radiator sales/repair organisation. It really is basic electrochemical science but of course not everybody understands that. However it does not stop them from espousing their un-educated opinions.
