GC 1705 Starting in cold weather

[LevesqueOnline]

Good day,

its really cold where I live, we hit -30 C, I am wondering how long I should keep the key turned for the glow plugs to work? I usually just count to 20-25 but sometimes it still starts rough

tks

Well your definitely on the right track.you might do your count to 20 and then let off the glow plugs and then turn them right back on for a 20 count. Do this 2-3 times if it is real cold. See if that don't help with your cold starts.

This is also what I do and I have a battery tender I put on if it is real cold. If it don't start after about 6 or so cranks I glow it another 15 seconds.

I think I would also get a block heater for those temps.

Mine starts easily, in cold weather.

Open the throttle about 1/4 of the way. 20-30 seconds of glow plug time.

If it doesn't start after a few seconds of cranking, go back to the glow plugs, and try again.

If it runs rough when it starts, you didn't have the glow plugs on long enough, or you may have a bad one.

Thanks all, my first diesel anything so didnt really get the glow plug thing. I do have a battery tender and if i know im going out i will plugin the block heater for 2-3 hours prior but sometimes just dont have that opportunity.

I will try turn on for 20-30. turn off tractor turn on for another 20-30 then start.

I don't see any point in heating them, stopping, and heating them again.

Heat them up, and start the tractor.

You have to find the amount of heating time, and throttle setting that works best for you, at a given temperature, through trial and error.

Just don't make the rookie mistake of cranking it until the battery dies. If it doesn't fire in five seconds, it's not going to start. go back to the glow plugs. And, try a different throttle setting.

I think a battery tender, hot plug helps a lot. The battery should have enough cca to turn the engine over quickly even in cooold weather. This engine will not start if its a slow crank, even at 1\8 throttle.
That being said, I am up for a new battery, mine is showing its age at 8 years old but with block heater, battery tender, 1\8th throttle, and 1-2 shots of glow plug time for 15-20 sec it starts right up.

At risk of insulting your knowledge of diesels, based on what you said about "not really getting the glow plug thing," I'll make a couple of quick comments:

Any diesel works on the principle of high compression ratio, squeezing the fuel air mixture in the cylinder to the point where it gets hot enough to ignite. Whatever margin there was for that process is deteriorated & less in cold conditions. To offset the cold, glow plugs are "dead short" resistive heating elements in the combustion chamber, one in every cylinder. A few seconds of them glowing red hot inside the engine heats the combustion chamber enough to significantly help with starting.

You will soon learn by cut/try how long you need to keep the glow plugs on for your machine for a particular temperature.
