What temp does diesel freeze at?

I used to light a bonfire underneath mine.

I remember two new boys doing that in the hotelNational in belgrade, but they forgot to take the filler caps off and t5he tank blew up.

When i was running to warsaw once a month,i used to put about 70lts of diesel and add 4ltrs of petrol that did the trick as long as you didn,t light a fire under the tank.

Sorry for double post.

The Germans in Russia used to light fires under their tanks to get them going of a morning.

When I was stationed in Germany in the sixties I worked with a German guy who had served on the Russia Front in World War 2. He told me that on some nights in the winter they had to drain the engine oil out of the tanks ( tanks as in Panzer ) and keep it boiling in a drum over a fire so that it wouldn’t freeze. I have no reason to disbelieve him.
I don’t know if it was a myth but some drivers used to say that if you put a sidelight bulb on a wire with a twelve volt current into your diesel tank then this would prevent the diesel from waxing. I dont know if this was true or not as I never tried it, although I can remember burning a wooden tilt board on a couple of occasions.

I was thinking of this old trick earlier.
Could a modern vehicle avec god knows how many computers running it actually cope or would it seriously damage it■■?

A neighbour used a blowlamp on his diesel tank a couple days ago, it was a plastic tank :unamused:

I ask as I jumped in my Renault premium truck at 4 am Saturday morning, temp gauge was registering -10c, started the engine and a warning came up on the screen saying something like

“SOMETHING SOMETHING FUEL BLEED” when I saw it I assumed it meant the engine was being starved of diesel as that’s why you bleed the tank when you conk out because your tank is empty, but I had a full tank. Gave it a few good revs to check it was getting diesel into the engine and it seemed fine and left it to idle while I did my paper work and jumped out cab to do my walk round.

Jumped back in my cab 10 mins later and the warning has disappeared. So was it just because it was cold and the EM thought it was being starved of diesel it never came on again during the day and it stayed -10c all day, had to pour hot water (not boiling) into my water tank to clear the windscreen

is their a safe way to un-freeze a tank of diesel which does not have a tank heater :question: :question:

you’ve got water in the filter.

I just read this whole thread again and noticed this. I answered the thread title and not the content.

Limeyphil spotted what you actually wrote and he correctly said you have got water in the fuel filter :exclamation:

You mentioned about bleeding the fuel tank, that is not correct, you bleed air out of the fuel system. In the old days by tilting the cab, loosening the filter bleed screw, pump bleed and finally cracking the injector pipes slightly. Then either winding the motor on the key or using the hand pump. Nowadays you just sit at the side of the road and call the depot :open_mouth:

As for the water in the fuel filter, on modern engines there is a switch on the dash that does the fitters work for him, don’t press it while out on the road or you will kill a motorcyclist.

YOU still can see lots of trucks who have a
water filtration system fitted between the
tank and pump and injectors the Germans
seem to be one of the best builders of such
systems as when i have seen one it has all
ways been a German manufacture no mater
if the lorry was Dutch German etc.,

While running for a french firm in the seventies it was always a gallon of petrol with a full tank of diesel, never any problem then. :

“Actuate Fuel Bleed”
There is a water collection tank on the underside somewhere.
As this fills up you will start to get the warning, classic time is under braking, the water moves and sets the sensor off.

Once the collectoe becomes full the warning will stay on constantly.

To empty - As the symbol says - “Actuate fuel bleed”

Switch is down right hand side of dashboard.

Certain conditions need to be met before you can empty it.

  1. The warning must be on permanntly
  2. The engine must be running
  3. The vehicle must be stationery

Now actuate the fuel bleed button - Apuddle of water/diesel will now appear beneath the lorry :wink:

Hence the reason for not draining it on the road and killing a motorcyclist!

There was a warning in the paper several years ago

very apt backing track for this current time :wink:

my fuel filters failed in norway yesterday temp got down to -14 the fitter that came out to me said the filters had wax,t up looked like earwax also uk fuel isnt good for really cold conditions norway derv has extra additavies acording to fitter,so 1400krone for new filter and call out costly mistake.

Barry can you not get the fuel filter moved to the back of the cab
and also fit a heating element along the pipes , plus clagg and box it
, then all you need is to carry your own spare filters and its easy
to change them, no tipping the cabin needed

had a problem in sweden in january, the tanks had spanish diesel in them, took about 20 seconds to crank it up, it was +5c…

Cap full of brake fluid in a full tank used to be my way of keeping the fuel from snotting up, treated Speaktrans to a tot in his new FH12 when he 1st got it, it really did’nt seem to like it & ended up having a couple of injectors replaced thankfully under warranty.

The Germans in Russia used to light fires under their tanks to get them going of a morning.

So did the Brits in Italy… but don’t try it today with plastic fuel lines!

The fuel here is treated for down to -40 from November till May but we still use conditioner in it. Newer engines which can only use ULSD cannot use the older additives but there are newer mixes out for them.

Common rail motors constantly circulate the fuel returning what is unburned to the tank so if it is really cold you can idle the motor at 1000 rpm and it will keep the tank warm. Most freezing will occur on the metal unions on the lines and filter housing and congest the lines from the lift pump. One of the hot air guns will free it up if it is the lines but you have to be careful and you will also need to handprime the engine to get clear fuel into the lines. To free up a badly gelled tank use a sheet or ply boards to shield the tanks then run a space heater under it for a couple of hours.

The engine oil thing is no myth. We have to plug in block heaters here to keep the oil from going solid. Once you get it started the oil is too thick for the tappets as well and the oil pump can hardly push it so the oil pressure warning light won’t go out for about 30 seconds…
