Hi guys, I would like to ask for some information. I have a Defender Td5 and as soon as I got the Nanocom I noticed that the water temperature of my Defender came to a maximum of 82 degrees driving slowly with rare peak of 87 going fast on the highway and had not an idle temperature infact if I stopped or in the traffic the water temperature began to fall even reaching 75 degrees.

Reading the Nanocom's manual and after a quick search on internat I known that the hot temperature should be around the 88-89 degrees.

For fear of damage to the car I asked to a mechanical to replace the thermostat and while I take this opportunity to completely replace the coolant with a 50% OAT original Land Rover antifreeze.

Now the idle temperature is 89 degrees and is around 92 degrees going up in city and highway about 90km/ h with peaks of 94 on the highway going fast. (ambient temp near 5 degrees)

What do you think? Is Now the cooling temp correct? What temperature do you have on your Td5?
 
Now it's as it should be....that's the normal behaviour, your thermostat was blocked open... if the temp. will go higher than 100 check the viscous fan to not be worn out and in this case it doesnt block well... when it's up at around 90*C keep gently a piece of foam or a carrot or something(not your hand!!!) against the fan blades, at that temp the viscous coupling must be blocked...if you can stop the blades then you need a new viscous fan aswell.
