Not in winter as long as your radiator/cooling system is working correctly ! I have even towed 3.5t trailers without the visco fan on 200,300tdi and TD5's!
Land Rover over cool them for extreme desert situations.

Winterizing a Defender, check all the door seals and adjust the locks so they close tight with no gaps around the door. Piece of linoleum over the rad. Works better than the rad muff. Blank off the rear part of the cab so less area to heat up. Check the Heater matrix is not blocked and no leaves blocking the airflow to the heater fan. Buy yourself a good warm coat, scarf and gloves. Line the floor areas with carpet to give better insulation. Then hope its not going to be too cold this winter. And hope the inside doesn't get flooded and soak all your carpeting.

Always got my shower squeege to clear the inside of the screen every minute
My original heater matrix was as warm as toast on my 200tdi even tooooo warm
But it got bust ! (long story) and got sent a replacement one in a blue box
can't you just think of the time, effort and money wasted fitting a britpart.. surely that boiling blood will keep you warm
Anyone know where to get the rad-haz sets for a 90?
Plenty of 110 but can bugger all for the 90!
Also any suggestions for those of us with full width intercoolers in terms of rad muffs ... will it cause issues?
I cant get my 300 up to middle on the temp gauge and that was when it was sunny! Comes off cold, but only just and sits there ... will sometimes get up to middle, but withint a few minutes drop right back down again!
That's with a recent pump, coolant etc etc

No, I tested my 300 last year with and without a makeshift rad muff, made sod all difference, water isnt flowing round the rad until the temps up anyway, and if the stat if working properly, it will modulate the cooling.
Removing the fan didnt seem to change owt either.

Thermostat?? mines up to temp in 5 mins, 10 if its really cold and stays bang on middle.
A possibility ... I dont think the one on it is very old but I do have one on the shelf ready and waiting. Just need to find the time.
that doesn't sound dangerous
try shoving polystyrene in, it'll melt but should be harder to catch fire. it will also insulate better

i was always under the impression a rad muf was to stop the rad from iceing in extreem temps, not to make the engine run hotter, as you say thats what the thermostat is for. used to take an age to warm up but since fitting a new stat it warms up in the first 2 miles of driving and sits spot on middle of the dial, weather moveing of static...
i''ve just confused myself!

Afaik they are used in extremes to keep heat in the engine bay and reduce the draught, watch ice road truckers, they still leave the viscous fan on the trucks.

Tried a radiator muff on mine, didn't make much difference really.
I have fitted an additional heater under the back seats that runs from the cooling system, that's helped a lot.
T7designs sell lots. Easy to fit and helps with the heat in the back.
Defender heaters are pretty good once the engine is warmed up. But of course this can take a little while with a huge lump of iron!
