Yip new viscous coupling or run it in this weather and just leave the AC on and you have enough to cool the engine as long as the cooling system is in good nick Its more for the very hot climates and lots and lots of slow moving traffic really.

Driving in south of France at the minute , high 20s temps. I have my coolant temp showing on hidden menu, it's been reading between 88-100degrees depending on terrain, included some big motorway hills . Typically 90-92.

Most likely as thinner air offers less cooling and if the engine is working hard it will be hot. the AC fan is more than able to cope in most conditions without the viscous unit IMO. FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

As per my original post, if I red lined my TD6 (which I had then) the fan would invariably disengage after a lot of howling!

Yeah but the TD6 should redline every now and again anyway to clear the soot from the exhaust regularly anyway and help clear crud from the exhaust turbine vanes/housing that builds up FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

I had a TD6 in Scotland and was constantly having to rev the engine hard after re start or next morning after towing something to get the viscous fan to dis-engage , I now have a supercharged in WA ( and I don't have to tell you how hot it can get ) and hardly ever hear the thing kick in so I would have to say its a minor failing of the BMW desiesel . 2008 MY Supercharged

Don't rev it to max!! The fan is designed to run at below engine revs, it may disintegrate with the disastrous results, tales of blades puncturing the bonnet! |

Is this an easy thing to remove... It is really starting to annoy me and is so loud. I only have to be in traffic for a couple of mis and it is wooshing all over the place... |

Easy to remove? If you have the right tools. You will need a couple of viscous fan spanners, recognition that it is on a left handed thread, and some patience to release the fan shroud. .

The visscous fan on the Supercharged also has an element of ECU control so it will screw things up if you remove it..... Stolen / Gone: 2006MY Supercharged LPG Autobiography - Zambezi Silver with Sand/Jet/Jet Oxford Leather..... |
