Engine temp for a TD5

[nedflanders]

Hi, just about to fit an Engine Guardian and was wondering if anyone else has one on a TD5 and what sort of temp I'll be setting it at. I realise the temp can be affected by load, speed and towing etc, but what sort of temp is getting to be classed as on the high side when towing and you'd consider slowing down etc.

I think normal op temps are around 85 95. over 100 I would start wathcing it and try to back off.

ID set it to about 115 degrees

Agree with Dave 115 sounds about right
I find that mine will run at 94 degrees water temperature on a hot day
It really depends where you put your sensor if its a bolt on unit

I recently fitted a Madman EMS 2 to my D2 Td5. Engine temps have been in the range 86-95 degrees. I will check the max values later after I've been off road today. I haven't done any towing yet so I can't comment on the figures for that.

Thanks for the replies, gives me a good idea what sort of temps I should be seeing. Been meaning to fit one of these for awhile, seen too many people with seized engines after loosing all the coolant and the temp gauge not telling them :eek2:

Not sure what type of sensor you are using - but the bolt on one I have on my td5 130DC defender reads lower than the coolant temp reading on a Nanocom

Normal temps with a load on a hot day on the Nanocom are mid 90's to low 100's - but the bolt on sensor might be reading abt 80 to 85.

So would agree with the earlier comment abt the location of the sensor being important - and would suggest a comparison with a Nanocom temperature reading might be worthwhile.

My bolt on sensor is set to go off at 90

I have a TM2 gauge on my d2 TD5.

It is under the dipstick bolt. I get 85 normal running temp up to 95 on big hill climbs.

The guardian normaly comes with a red button to lift the alarm temp by15 degrees in 3 * 5 degree steps. I have set my alarm temp a few degrees higher than the vehicle normaly runs. ( 80 - 85 ) if the alarm activates due to towing or being stuck in trafic on a hot day etc you can easily raise the set point with a quick push of the button.
this way you are aware of any lift in temp very early and can make an informed decision as to the cause.
hope this helps Dave
PS my sensor is near the water hose on the front of the head and normaly reads 5 or 6 degrees lower than nanocom.

if you're going onto a bolt on item thats not in the hot side of the cooling system then depending on where you bolt it onto the engine the temperature will need appropriate adjustment.

it is possible to run the engine coolant temperature up faster than the block metal heats up and blow out the cooling system before a bolt mounted sensor lets go.

Well fitted the Engine guardian, relatively straight forward. Twin sensor set up, one on the rear engine lifting bracket and one on the gearbox. The engine one may well need to be moved as its the 70's after a 30min drive. It does suggest putting it around the front of the head where the coolant goes in but this would put it in the air from the fan. Have set it to activate 2 relays with an option of a 3rd. First one is the A/C fan cuts in and cuts the A/C compressor off and the second is the horn at around 100deg in case I'm out of the car when it's running. Looks a very well made bit of kit :)

;) hi there have been a lot of questions about overheating. I'd like to add , the defenders and disco 2 ,have a plastic pipe (about 5mm inside diam.) that runs from the top right hand side of radiator to the expantion tank . The first 1/3 can't be seen ,as it runs under the radiator shroud. This pipe goes brittle and cracks. I know as it happend to me . It also happend to a mate of mine , on his disco 2. I also told another mate to check his , and yes his had gone brittle as well , so its worth checking out .it could save you a lot of money . regards .jimr1 :)

Cheers Jim, any coolant loss can end in big bills, which is why I fitted the EG, I worked as a breakdown mechanic in the UK and saw lots of engines that had been cooked and the owner was adamant the gauge had read normal. Ford had a good system of measuring the head temp rather than coolant temp, if it overheated it went into limp mode.
I've checked my engine sensor on the EG and moved it as it was about a 3degree difference from the front of the head to the back of the block. Recently did a powerlines trip and due to the outside temp left the car running for the A/C when I was out looking at obstacles. I was always concious if it was to overheat sods law would be it was when I was outside. Now the fan will kick in followed by the horn if the fan continues to rise. I think it a worthy investment if it saves the engine :)

:) Hi mate iv'e been looking at temp warning cencers for a while now . So decition made . i like the look of the one from the USA is that the way your going .regards jimr1.;)

[nedflanders]

Yes went with the American one, liked the look of the display and the fact each of the 3 relays can be set at different temperatures and for different sensors. Took less than a week for delivery from the States to Perth :)
