Discovery 11 Engine & Transmission Temps

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.

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:;)

Attachment 87518

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.

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.
