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.

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.

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.

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

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.

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.

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
