winterization and rad muffs?????

hi there,

my 90 is having difficulty getting up to temperature at the moment. the outside temp is any where from -5 to -24. do ineed a rad muff?? and is there anything i can do about fuel waxing the other deisels are dropping off like flys and mine is experiencing some difficulties in starting. any help is much appreciated.

new glow plugs.

Then, check your thermostat. The engine, while being used (i.e. not at tickover) should still maintain temperature.

ok cheers.

sounds like a trip to the spare shop is on the cards

at those temps you may need to check your oil rating and coolent operating temps, as these will not help matters. I cannot remeber the ratings for the temp -5 - -25 but if the stuff in is for hot climate i think it went south at 0 and temprate climate stuff i dont think reached -25 but i'll try and find out for you.

there is a fuel additive for derv at low temps but its usually done at the production stage these days, if the temps are normal for where you live it should be ok, though you can probibally but it off the shelf.

done a quick ref. check fuel additives should go in at ~4 C and will work down to ~-40 C,

the oil you want for winter is 0W or 5W second number as close to the manafacturer spec as possible.

Remove the radiator fan.
Not needed at those temps.
I have a friend in Norway who adds a litre of white spirit to a tank of diesel to help prevent waxing.
Norway uses winter diesel but he swears by white spirit. Dont use turps.
Not tried it myself as I've never had a problem so you do this at your own risk if you chose to do so.
Anybody else heard of this ?????

I used to use parraffin ( about 5%) in my old truck when it was very cold and had no problems.
Rad muff I would say is a must in those temps, I have 80% of my rad blocked off with cardboard and temp comes up quick and stays at normal all the time even when pulling hard with a trailer.
My mate has had a muff on his 90 for about 2 months now, he just rolls a bit down depending on the temp, when below freezing he has it muffed off completely (2.5td) and says it runs nice and warm with no overheating.

At those temps you also want to remove the jiggle pin from the thermostat.

Driving along the wind chill can flash freeze the rad and split it antifreeze or not.

The British army did this to all the landrovers/trucks etc. when we were in Germany during the cold war.

We use Kero for a winter diesel mix at sea (lifeboats etc). Usually comes as a pre-mixed 'winter diesel' but would imagine about a 10% dilution would be about right.

Used to have a 2.3 diesel Shogun. The handbook said you could mix petrol and diesel up to 50:50 for cold climates. Don't think I'd go quite that far though. Not much lubrication left for the pump.

thanks guys,

a great help!!

i have loads of things to try out cheers all sounds like good adivice. i'll give it a go tomorow.

but i'll say one thing at least the landy still goes a lot of the deisel cars at work have just died.
