What did you do with your Range Rover today

[Grrrrrr]

Most ECU controlled electric fans don't kick in til 105° or so. So long as the needle doesn't climb, I'd give it a damned good ignoring.

Oddly enough I might modify the aircon fans to kick in at 95.

 

[Grrrrrr]

Only poorly maintained diesels die of gasket failure and cracked noggins...

I don't think so. That M51 head is its weak point. That's why later models pull in the aircon fans as well. That's on top of the Land Rover rad which is a thicker core than the aftermarket ones. Most of the time it is fine but work it hard all the time and that head cracks, especially if you put a tuning box on it to throw more fuel in.

22mpg or 7mpg at full chat

Sounds like my rr then

Not convinced my viscous is as efficient as it should be. Or maybe the radiator. Although the needle doesn't move my Engine Guard informs me the head temperature is creeping up over 95C on long steep hills.

That is perfectly normal, the max operating temperature is 105C.

 

[Datatek]

If you go above 95 at the head on a doozle you wont ignore it for long, Itl give you no choice

Nonsense, the max normal operating temperature is 105C, I use electric cooling and the fans come on around 100C.

The aircon fans on later models kick in from the third sensor at about 110C

The bmw straight 6 petrol was a great engine!

Now the bmw v8 petrol .. hmm!!

Not the oil guzzling one I had from neew.

Kicking in at 95C, they will be running far too often.

from my experience with the viscous on the v8.. when it started to fail, the average running temp while driving clicked up a degree or 2. swapped the viscous and it dropped back down again

what temp is the thermostat fully open at? i'd go a couple of degrees or so above that

80C from memory, the fans would run all the time set to that temperature even when RAM air made them unneccesary.

 

[RangeRoller dt]

105 degrees, if he is happy with that so be it, personally i would not be. The engine should run in the 85 to 95 degree range for long life.

Not nonsense. I prefer incremental cooling.

 

[RangeRoller dt]

I know I fu"king want one as well

I shouldn’t be allowed one. The things I’ve done to P38s would be pure sacrilege on one of them

It rarely breaks 95C. Prolonged hills, especially when towing.

Indeed. How's the hair-shirt? Still itching?

My sensor is bolted to the head so probably a few degrees cooler than the head itself and maybe a few degrees below the coolant as well.

Usually it runs between 85 and 95C on my sensor. Thermostat opens at 82, I think. The air con fans come in too late on the later models for my liking. Already cooking the head by then.

I do agree with that

 

[RangeRoller dt]

Still got a tickle in the throat from the midget gems I found in the pocket. I’m sure they weren’t all black to begin with

 

[Datatek]

The optimum operating temperature is 95C, as the late Wammers said, normal operation is between 85 & 95C. 105C is within the normal range but is rarely reached. The dash gauge stays at mid point from 85C to 105C.

Yes, the sensor for the aircon fans comes on much too late at between 110 & 115C on my tests so is actually useless.
