Hello just back home from travelling through alpine country over easter ,last night temperature dropped to the point where a glass of white wine left out froze solid plus all water etc anyway when we tried to start a gu 3litre and gq 4.2 diesals ,both would turn ower freelybut would not fire after many attempts.We pushed the vehicles into the sun and poured hot water over fuel pumps etc and away they went. Question is surely these vehicles should have started after all winter isnt really here yet,we want to go back in approx 4 weeks and not get stranded.We fuelled up in jindabine thinking we would get alpine blend preventing this.....Any ideas to improve starting?????

Could try giving the glow plugs a couple of goes at getting warm enough by turning key on wait a minute turn off without starting and repeat process. I don't know if this works for sure but I remember someone telling me this some time back, maybe BS though.

I have had no worries starting diesals in freezing conditions but that wasnt in the alpine areas. I would guess it is too early for the alpine areas to be stocking Alpine diesal which i understand is further refined to reduce the wax content perhaps that is all it is

Brian,

Two dabs at the glow plugs is a good idea, particularly with indirect injection diesel engines. I THINK the 4.2 is indirect injection - can't remember.

Otherwise get yourself a can of "Aerostart". It's an ether based spray that you spray into the air intake - the closer to the actual air filter, the better. i.e spraying it through the snorkel is gonna take a longer to get through to the engine itself.

There are various stories about "Aerostart" damaging engines - but it's all BS. The engine was prolly "goosed" to start off with.

Use it - it works. It's what it was designed for.

We had another name for "Aerostart" when I was working in the colder climate areas many years ago before seeing the light and moving to QLD, we called it "Heroin" because once an engine had one sniff of it the bugger wouldnt start without it!!!!!

Back in the "bad old days" as an apprentice, we used to spray it on some poor unfortunate kids overalls and watch him keel over!!

Can't do that these days!

Hi if using aero start know the risks!!!!!

Too much can result in severe overspeed or high revs at cold start and no oil circulation = engine damage long term.

I used aerostart on 110 and 71 series diesels for years (only way they would start sometimes) and suggest IF using aerostart crank engine over first as someone commences to spray aero start into air intake judiciously.

Also if engine doesn't fire,,, stop,,, as oil is wiped off cylinder walls = more long term damage.

brian,
Another way that a mate showed me just last year in Diamantina Lakes area and the 2H glow plugs chucked it in (2 deg.), was to remove the flexible air intake hose and hold a diesel soaked burning rag close while cranking. Worked like a charm. After that always made sure i parked facing the morning sun. This won't improve starting, just another way if in a pickle.
Cheers,

your fuel probably started to wax up. It's a little early for Alpine mix at the stations. I fueled up at Bruthen yesterday and saw an aditive on the shelf. The lady said they don't sell alping mix anymore only the additive. I can't for the life of me remember it's name. Could always call them. No amount of 'glow plug' preheats will start the engine if this is the case. For the record I haven't had starting probs in winter when using alpine mix in winter in my GU 3.0l

Brian,

It was cold Monday morning. -5 at 6:30 where we camped.

I had the same problem trying to start the Troopie, I left the bonnet up all night and that did not help.

To get going I poured hot water over the fuel filters, this melted the wax and was then able to start.

Even glowing the plugs several times before trying to start didn't help.

When I go the the Vic High Country next week I am going to keep the bonnet down and wrap the filters in a blanket.

The Alpine mix should be down here soon, I don,t think they expected it to be so cold this early in the year.

I hope the rest of the trip was good, and we might catch up again some where down there in the future and have a bit more time to talk.

Wayne

Don't forget to tie something to the steering wheel to remind you to remove the blanket under the bonnet ! You do not want an engine fire !!!

Had the same problem with my Jeep at Native Dog Flat - after getting down to -10 during the night it was still -7 at 7AM. Some hot water on the fuel filter solved the problem.

Hi, I always added FUEL ADDITIVE like Power-Plus Deisel into the tank, which always works fine for the High Country.

I've been in minus temps where the two diesel disco's froze, but the troopy just started fine (bit rough to start - but soon warmed up).

The additive gives a higher temp point to create solids.

I remember on frosty winter morning back in the UK, lighting fires with rgas soaked in kero, under truck diesel tanks just get the fuel to de-wax. Then using compressed air to blow out wax plugs in the fuel pick up line in the tank. Mind you it used to get down to minus 10C some nights.

Aaaaahhhhh!! "I love the smell of diesel smoke in the morning" - pardon the paraphrasing.

Wayne,might see you there between 22-25/4 we also thought the wax was seperating due to low temps checked spare fuel drums we carried and they had small clear particals floating in the fuel these particals would not pass through the filter in our funnelStill not impressed that both vehicles would not start easily,will pay more attention next time..

It's fairly common to add 10% petrol to the tankful of diesel for low temperature starts too.
