Bansh-eman Posted January 16, 2007 Report Share Posted January 16, 2007 ok so im from texas and it dosent get that cool and right now i live in san diego... so for your truck to start you got to warm the glow plugs... which heat the cylinders so the fuel will have enough pressure and heat to ignite... when your in freezing temps how well does a deisel run or start being that it takes much more to heat it up prior to starting? if you dont drive a deisel or have experiance plz dont add your 2 cents... im trying to answer a question for a freind and im not looking for opinions, trying to find facts, thanks Quote Link to comment Share on other sites More sharing options...
johnsmith1973 Posted January 16, 2007 Report Share Posted January 16, 2007 2004 duramax diesel, hold the key til the coil/glow plug light goes out (<5 seconds) starts right up, even in single digits. Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted January 16, 2007 Author Report Share Posted January 16, 2007 2004 duramax diesel, hold the key til the coil/glow plug light goes out (<5 seconds) starts right up, even in single digits. so even at that low of temps the glow plugs will still get the cylinders hot enough to start fine?

blaster668 Posted January 16, 2007 Report Share Posted January 16, 2007 Newer diesels are much better at starting than the old ones. Engine block heaters are often used as well. Quote Link to comment Share on other sites More sharing options...

blaster668 Posted January 17, 2007 Report Share Posted January 17, 2007 Usually it is an option added from the factory but aftermarket ones are available. Here is one from JC Whitney. You just plug it in to an extension cord and it heats the block, pretty simple. It's not something you just plug in, wait five seconds and go. It is basically meant to be left on all the time when the vehicle is parked and it's cold. http://www.jcwhitney.com/autoparts/Product...101/TID-8043873 Quote Link to comment Share on other sites More sharing options...
Dinner Posted January 17, 2007 Report Share Posted January 17, 2007 (edited) Ford and GM Diesels both us Glow Plug's to heat the air in each cylinder, while Dodge has a Grid Heater in the Air Horn that heat's the incoming air, and will shut off once the engine reaches a certain temperature. As said above the never diesels are even better for starting in cold weather, but even still the older generations are good too. If it is not too cold out, let's say -5 to -10, you can still start your truck, though it may take a few cycles of the grid heaters, or glow plugs. If it get's colder out though, then you can plug your truck in(this is the block heater mentioned above). You plug it in through an extension cord, and it heats the block. My truck already has a block heater built in, so the little cord to plug it in is found on the passenger side, right under the front grill. The best thing to do is right after you shut your truck off, plug it in. Since the block is already warm, it is easier on the block heater to keep the engine warm, rather than bringing it up to temp, and then keeping it warm. It was -10 the other day and my truck started on the 2nd crank, wasn't pluged in. Today it was -5 out, inch layer of ice on the truck(stupid freezing rain) and it started first crank(waited for grid heater). So usually you can go pretty low in temperature with Diesel's. Hope this help's :thumbsup: Dinner Edited January 17, 2007 by Dinner Quote Link to comment Share on other sites More sharing options...
HotCarl Posted January 17, 2007 Report Share Posted January 17, 2007 when we were back in colorado it was 0 degrees and we plugged in the block heater into our chevy and it started like it was 80 outside. we forgot one day and the truck was hard to start but really it wasn't like it wasn't going to start. it just cranked a feel more times then normal.

locogato11283 Posted January 17, 2007 Report Share Posted January 17, 2007 glow plugs in my 2001 cummins take a lot longer in the winter, even as long as a couple mins when its really cold. with 2 batteries though crankin over has never really been a problem. ive had my truck 4 years and never plugged it in over night..

dajogejr Posted January 17, 2007 Report Share Posted January 17, 2007 Greg.. My buddy has an older powerstroke... He has a programmable device that has a little panel that sits in the passenger compartment. It splices in with a radiator line running to the block, and it heats/circulates water in the block. You can actually program it to start circulating and heating at a certain time (say 2 to 3 hours before you wake up for work, etc.) I thought it was pretty nifty....

blaster668 Posted January 17, 2007 Report Share Posted January 17, 2007 The glow plugs will do fine IF they are working properly. Also, the block heater I showed is not a very good one, just so you got a better idea of it. There is a way to test glow plugs for resistance but I'm not sure of the procedure...maybe you can look it up online. Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted January 17, 2007 Author Report Share Posted January 17, 2007 well i got a 2006 Dodge 2500 Cummins Turbo Deisel... and thats what we where talking about being in Omaha... i guess cranking wouldnt be the problem... i should probly worry more about the coolant freezing and cracking the block as it melts? i dont know im not from anywhere that gets that cold Quote Link to comment Share on other sites More sharing options...
blaster668 Posted January 17, 2007 Report Share Posted January 17, 2007 If the coolant is 50/50 water/antifreeze, which is normal, it should be good down to I believe like -30 F Quote Link to comment Share on other sites More sharing options...
