What is the normal operating temp for my 2005 lr3? Mine has been running between 205-215. I'm coming from a 2004 discovery II. This was too high of a temp for that truck. I'm just wondering if this is normal. Thanks.

 

A D2 should be 185F-205F with an OEM 180F Grey Thermostat. With the OEM 190F thermostat it would be 195-215F range.

From what I saw with my 06 4.4L V8 LR3 here in SETX it seemed to top off at 206F as the normal operating temp using a Scaguage II to monitor the temp's when I first got it.

 

LR3 should be 195-200ish

thermostat opens fully at 197F, when happy the truck should stay around 196-198. Yours seems a little hot?

 

Thanks for the replies you guys. I have only had this truck for a month or so. I think I'll replace the thermostat for good measure and see if that takes care of it.

 

SETX is certainly what I'd call a bit "hot" so 206F with the AC on in traffic or 80MPH does not seem high to me. I monitored it when I first bought it and on the way to go look at it & buy it my company van overheated almost the entire way there (it's never done that). That's when I saw 206F with the AC on after driving in heavy traffic and 80MPH after that in the LR3.

 

I am up here in the near Arctic so my temperatures run cooler - closer to 195F with the stock 190F thermostat, and yes, there is snow on the ground right now and has been for the last three weeks.

Below is a table of "normal" temperatures relative to the factory temp gauge needle - not exactly a testament to precision and detail.

Needless to say, that is one reason I got my ScanGauge - to find out system voltage and coolant temperature.

Re coolant temperature, it depends where you read it; as such, I wondered where the 215F reading came from.

The ScanGauge temp comes from I presume the engine computer and I suppose it gets it somehow from the coolant temperature sensor but who knows what sort of interface there is with the oil temperature sensor.

There is some sort of sharing of info as apparently the oil temp sensor will if not shut down the engine, then at least red line the temp gauge under certain parameters if it senses the coolant temp sensor is not doing its job.

Unfortunately, the ScanGauge does not seem to separately monitor engine oil temperature, nor tranny temperature either.


Engine Coolant Temperature ºC (ºF)---Needle Pointer Position

Ignition off----------------------------------- Park position
40 (104)--------------------------------------Cold Blue segment
75 - 115 (167 - 239)-------------------------Normal
120 (248)-------------------------------------Start of hot (Red segment)
125 (257)-------------------------------------End of hot

 

That temp range is ridiculous, by that time its like telling you after the fact...
