Cold Weather Starting

What temperature do you guys plug your trucks in to help with starting?
I just replaced the glowplugs and the timer and I am having trouble cranking my truck. It usually takes 2 times of glowplugging for it to hit. I can plug it up and it will crank right up. Anything I should check? Or does this sound about normal?

my rig will start in anything above zero F*. I cycle them twice, crank for 4-7 secs and shes right up there. Below 0, it will start also, but sometimes more cranking is needed. I am usuaully up two hourse before I need to leave, so I will plug her in from time to time just to make the starter have a happier day.

I tried some of those Japan/Bosch plugs, junk..I had 3 burn out within a few weeks.
I now have brand new Autolites. Temp ranges from 20-30 or so.

you will find the genreal consensus si that auotlites are also junk, and can lead to some serious problems such as broken or mushroomed tips. The only GP to use is the oem Motorcraft/Beru available at autozone for 9.99.
That dosent sound bad if it will crank right up in 20* then everything is more then likelyy working correctly.
I would still change to the oem GPs to aviod serious problems though.

I made the mistake of letting a guy put autolites in my truck, I asked him twice what he was putting in and when I checked they were autolites. Only saving grace is I made the place put right on the ticket a statement that they would be responsible for any problems or damage caused by not using oem glow plugs.

As for starting, I plug mine in at anything below 30 degrees. It will start at 10 degrees without plugging in, but it works hard to do it and not allows on the first try. I have my heater on a timer, it goes on for two hours from 1-3am and again for three hours from 5-8am, so it is ready when I jump in at 7:30am. The simple wall timer will really save on electric cost. I has been -10 degrees here the last three nights and she fires right up. Be careful cycling plugs to many times without giving them a break (5-10 seconds), it can overheat them and ruin them. Plug it in and you will have no problems.

Exclamation Using Autolite Glow Plugs?

If you've got Autolite Glow Plugs in a IDI, you'd better get them out of there, NOW!!! They WILL swell up or curl up inside the precup chamber and then when you try to remove it, it breaks off and falls down on the top of the piston. And there's not enough room there, so the tip either becomes imbedded in the piston or a valve gets bent as the tip trys to pass out. I've seen photos of both.

Did not know that about the Autolite glowplugs. I know that the glowplugs can swell but I thought that was from a bad timer that constantly heats the plug. I had this happen on a 6.2 diesel military blazer with AC plugs.
So the Motorcraft plugs made in Germany are the best?

So the Motorcraft plugs made in Germany are the best? YES, they should be THE ONLY brand that you use in these engines!!! The Motorcraft GPs can be left on for an hour(bench tested by someone on another forum) without any ill effects. Try that with a Autolite.

Just so no one goes and jumps their gp relay, or runa manual swicth and burn out a plug(s) This statement is completely false, inherenttly the way a glow plug works it will burn itself out. A 6 volt plug ona 12 volt system will not last that long, never. I have played with this, and found that the autolites can last about 12-17 secs. The two motorcraft plugs lasted about 17-19 seconds before they quit drawing current. But the motorcraft are a much better product.

I would advise you look at Ziggster40's web page before doing anything with Autolite GPs. http://www.members.shaw.ca/k2pilot/

You are correct, I came here to correct the post as I read Ziggsters webpage this morning. He said 60 seconds, NOT 60 minutes. I apologize for the error. A 'Senior Moment' or 'Old Timer's Disease'. Baja

Does anyone know anything about the WAP glow plugs that are being sold on eBay. They say they are the only U.S. made glow plug made. They offer a 2 year free replacement and say they have dual coils and heat up faster and hotter, with a low failure rate. It is eBay item number # 8020598987. They seem cheap even with the shipping.

I seen these plugs and wondered about them myself. A company makes for the military a glowplug for the HMMWV/Hummers that is very similar. This could be the company. They are supposed to heat up faster and supposed to be nonswelling. I had only seen them forsale for the 6.2/6.5 chevy diesels until now.
