Interesting Stuee, that could be part of the reason why it's never had as good a fuel consumption as other discoveries, wrong thermostat fitted? i could have always be running rich.stuee wrote:As far as I know the EFI operating temp of the rover motors is around 87 degrees anyway (82 for a carby). My disco (97 3.9v8) regularly reaches 95 as I have the switch set to come on around this time and cool down to around 90 as if you go below the operating temp it can mess with your fuel consumption.Blythe wrote:Hi guys - this is my first post here.
I have just fitted an AU fan assembly to my 94 disco which has a 4.6 RR motor in it - gets up to running temp much faster, fine on the flat, fine on undulating hills and fine in the city but on long uphill runs it gets hotter than with the original. never got above 85 with the viscous fan (viscous frozen which is why I have replaced it) but going up the M1 out of Adelaide yesterday it hit 95c
I am using a TM2 to control it via an external relay. Love the TM2 very accurate, not sure about the AU fans though. I am going to fit fatter wire to it (6mm2) to make sure the juice is getting through ok as I fitted it with 3mm2 since that was all I had but I think I have an unacceptable voltage drop, which I haven't actually measured yet.

I might bump the cut in temp up again then.
