To be honest i dont really have any problems with the patch - i may even have the latest it was only done around Nov.

Thanks guys

So it would seem its perfectly normal...and if i want to stand out in the cold either go in the disco or dont bother leaving the engine running - where is the temperature sender on the puma? Mike

Parked up at the station this morning and, given the train was running late, thought I'd do a (semi) controlled experiment for you.

Turned lights off but left the engine on and heating on setting 1 (high heat). It must have been around -4 outside.

Within 5 mins it had dropped to 1/4 way up the gauge. I reckon it would have been cool in another couple of mins. A quick check under the hood and the viscous fan was busily whirring away cooling the engine! One that started out as a 2.4 TDCi 110 XS

No fault. If, at -5 deg c or similar it was running at normal mid temp at tickover, then in the summer it would overheat towing a trailer up a hill, or general driving in a hot country. Doing away with the viscous fan and substituting it with an electric fan will make a difference, in the winter at least, but whether it can adequately cool the defender in 30 deg+ C temps, I'm not sure! Otherwise why do LR keep fitting a viscous fan? On my TD 5 I created a rad muff with a rectangular rubber house door mat which fitted perfectly using a metal coathanger to lock it into to place in 2 holes under the bonnet and used this all last winter to good effect, and then put the door mat back at home after hosing it off.

Quite so. What I was wondering was at what minimum temperature does diesel nowadays start to clog? The additives put in nowadays results in much lower temperatures can be achieved before this occurs, but what is the min temp? i seem to recall a while ago supermarket diesel was the best for lower temps, but maybe it's uniform now. We used to have to put additives in the truck diesel over 10 yrs ago, but not now.

Both my old Td5 and my tdci loose temp when stationary in the cold. It's got a lot of air space at the front I guess?. 1963 Series 2A truck cab

In extreme low temps, like -20 c, I'd prefer to get my diesel from well populated garages to avoid the risk of separation, and also leave the handbrake off but in gear to avoid it freezing on if driven thru snow/slush during the day. Same applies to EPBs.

Mine doesn't work very well when I pull it on so no danger of it freezing up Thumbs Up One that started out as a 2.4 TDCi 110 XS

Mine has been doing the same- when not on load the temp drops- but this is only expected on an efficient engine. But today after a play in the snow it didn't do it any more. Looks like a thick coating of snow across the whole grill was blocking airflow. From this I will probably be buying a grill muff for these cold days Smile.
