Engine Block Heater - How Cold???

It typically doesn't get below freezing where I live, but the overnight lows for the next three days are forecasted to be in the low 20°s. Is that cold enough to necessitate plugging in the engine block heater?? And, where the heck is the plug anyway??? I have a 2005 F-350 CrewCab w/ manual tranny (if that even matters...).

Lightbulb Try this . . .

Darlin', if you have a 6.0, '05 and up, the heater is built into the engine. If your truck had the option of the block heater ordered, the cord is tie wrapped behind the front right (passenger side) tow hook.

You do have the heater, the question is whether you have the cord to it, it needs to be on your invoice for $35 or so, in order for them to have install the optional cord.

If the cord is there, pull it out and take the rubber boot/cap off. It heats up the engine block antifreeze to 55` to assist in easier startups. You decide if it is too cold or not to plug in.

There are several places to buy a cord to self install, see my gallery. IH dealer, Ford dealer, FTE sponser Ford dealrs, etc.

Yes, I did order the truck with the heater & cord "just in case". We occasionally visit family up in Oregon where it really does get cold. I'll look for the plug when I get home. Thanks!!!

Great, go Get Er Dun . . . Might try putting on a timer as well so it is only on a few hours before you need to use in the morning, or whenever.

I treat mine with kindness; plug in if it goes below 30 - the amount of time before using the truck varies with the temp.

I would agree with him. I usually don't plug in unless below freezing. Otherwise I'll idle for 5 minutes or so but that really starts to drop mileage....

I've never had to plug mine in. I just give it a little while to warm up, guess I'm waiting for the day it doesn't start.

Best thing I've found when cold for plug in time is this: 20deg = 2hr; 10 deg = 3 hr; 0 deg = 6 hr; beyond that full time. This is for an outside vehicle.

I have an attached garage that stays about 45-50, maybe less if it is really cold out, but I still plug the pig in for about 3hrs before I start up in the winter. Main reason is to help the truck get me warmer sooner. Seat heaters help in that regard but I am a certified wuss when it comes to cold temps. Therefore, I plug.

If it were sitting outside and temps dipped below 40 or so, I would still do it for easier start up.

PS trekchick, nice bikes, although I ride Pennsylvania aluminum - Cannondale

It gets down right cold in upstate NY! I only plug the block heater in if it gets into the teens. Actually 15 degrees is my target temperature. I have never had a starting problem using this rule of thumb. I also let the engine warm up for 2 -3 minutes to make sure the oil is circulating well before driving the truck. Occassionly I do not have access to an outlet and usually the truck starts on the first cycle of the glow plugs. PS: I like the pic of you and your dog! Looks like a great companion.

According to the 2007 Diesel Suppliment:
P.11 The engine block heater must be used for starting when the temperature is -20F (-29C) or colder
When operating in cold weather , use a min of 45 Cetane Diesel or use Cetane Index improvers from a reputable manufacturer.
P.13 At temperatures of -4F (-20C) or below, it is recommended that you use an engine block heater to improve cold engine starting.

As stated above is out of the manual, My personal gauge is I like to plug it in around -5C (23F) and start to consider it a must for myself at -10C (14F) and below. I think a big contributing factor is what type of oil you have, 15W-40 will need the block heater (pan heater is better) sooner that the 0W-40 I am running in my truck.

Also I have read and anouther thread confirmed it that, more than 4 hours is a waste for the block heater.

I believe that International says that it is necessary to use it at temperatures of -20 celcius (you do the conversion). But I still like to plug mine in when ever the temps drop below freezing.

I agree with the oil concept and the time concept. Synthetic oil will be much easier on the engine, especially on cold start ups. I usually put my block heater on a timer for only 2 -3 hours, which seems to work out perfectly. My '03 manual really does not address specific temps for using the block heater. As always, one should follow the manufacturers recommendations.
