Discovery 11 Engine & Transmission Temps

[munoos]

I recently fitted an Engine Watchdog management system
I have fitted engine sensor to a bolt on top & at the rear & the transmission bottom front
When towing up long hills where I am in 3rd gear the engine temp claims too 100c & tranny goes to 95c
Both drop quickly once on flat ground but I was wondering are the temps too high

[sierrafery]

These temps seem quite normal to me...nothing to worry about IMO

TD5 or V8?

[munoos]

Sorry Td5 auto

Can't comment on the transmission (I have a manual) but I have an Engine Saver temp sensor on rear of engine which I've had for a couple of years.

Normal round town use (less than 80kph) in winter 88 to 90; in summer 89 to 91.
Motorway speeds (100kph) winter or summer 90 to 92 on flat; up to 95 on low hills; up to 98 on long climbs.

Recent highway trip, 40deg day, long steepish hill, got up to 102.

A/C adds 1 to 2 deg.

Of course the original temp gauge doesn't move from mid point.

Interestingly, from cold start, it takes a good 15 to 20 minutes at non highway for the temp to stabilise at around the 90 mark. Original temp gauge reaches normal mid point when temp sensor says about 60.

That's exactly how my manual is behaveing too

[Road Stone]

Mines and Auto but behaves in a similar fashion. Takes ages to heat up though.


Around town style driving about 78C and highway cruise about 88C.


This is at altitude (4000 ft) not sure if that changes things.


My readings are from Hawkeye.

Did I miss something? When did they release the discovery eleven? I thought we were only up to 4? :)

My D2 seems to be very similar to the above. Only saw temps higher than 100 a few times in >40c.

Readings from a madman ems1.

You blokes must have UK thermostats. The thermostat I bought is an 82C first open, and the OEM one I took out was82C and I am pretty sure it was in from new. D2 2002 TD5 auto.
Mine runs at usually about 82C-85C tootling around.

82-85C-maybe 87C on long hills at 100KMH in 34C-38C towing a 900KG-1 tonne camper trailer .

Only time it has ever reached 100C was on the climbs up to Cabramurra towing the camper on a 34C day.

If you have an 82c thermostat and running those temperatures IMHO you should be doing a back flush on your radiator or replacing it.

Gauge is cheapo LED gauge with dry sensor on outlet housing where ECU temp sensor is and agrees with Nanocom EVo within 0.5C.

Remember the engine watchdog is measuring engine metal temp not water temp so comparing the to is not really practical. You are understanding what temp your metal is a normal operating temp and looking for changes.

For example - my engine watchdog normal temp is 72 degrees while the water temp on my water gauge is about 90. When driving the max temp my watchdog gets to is is about 76 - over this when moving and I get concerned. But when stopped at traffic lights it may get to 80 and that is no issue as airflow over the engine is reduced. Water temps will normally sit between 90 and 95 but will get up to 100 when driving slowing in hot weather - the watchdog if the car is moving will only get to 76.

So you need to learn what is normal for your car.

Those watchdogs can lead people into a false sense of security. I have a client that asked me what my operating temperature was and was happy that his Watchdog only sat on around 75Deg. I was referring to my coolant temperature, he was referring to his metal temperature so there is a big difference.

[PhilipA]

As indicated mine is the same. The gauges should be calibrated against a nanocom which reads the ecu sensor.
A bloke visited me to clear errors, and I read his gauge at 6c less as he had the gauge at the back of the head.
Mine is on the outlet housing right next to the ecu sensor and reads the same.

Do you have a pic of that Phillip?:angel:;)

I got this made. To put the temp sensor on Madman ems1 into.

If it ever turns up from Sieth Eeefrika.

It has 2 tapped holes, one to suit OEM sender, 1 for the madman.

[PhilipA]

Do you have a pic of that Phillip?

What do you want a picture of? Where the sensor is mounted?

My D2a auto generally runs around 89-90 degrees. When towing a 1.5 ton camper temps at highway speed are around 91 degrees but have been as high as 107 degrees on long uphill sections. Generally, temps on shorter uphill sections are up to 100 degrees.


These temps are fro Nanocom readings.
