View Full Version : Where on earth is my block heater?

12-21-2004, 07:21 AM
'05 Ford 6.0 powerstroke diesel. I read on dieselmann's page that all 6.0's come with a block heater but only those in certain states come with the cord to plug it in. We bought in a state that is not listed as having the cord. Our selling dealer told us he was not aware they came with it, thought you have to order it. That was their service writer.

I can buy the cord but first want to make sure we have the block heater. Nowadays it's not easy to see up under the engine to the block. I know it should be in a location where a freeze plug would go but I can't find it. It's too darn cold to lay under there very long. I can't see to each of those locations and would have to do some feeling around but can't do that with a heavy coat on.

Anybody know where the block heater is on the '05 Ford 6.0? On our '03 the cord was on the passenger side of the grill so I assume it was on that side. I would think the '05 would be in the same location. I need to find where that cord would attach to before I spring for $60 for the cord. Don't want to buy it and then find out we don't have the block heater.

Can't help you with the 05 but all of my trucks have always had it on the passenger side. My old Ford, my new Dodge and my husbands GMC all on the passenger side. My Dodge I can pop threw the grill my husbands GMC is up to high, almost on the top of the stuff under the hood. No way to fit threw the grill.

Can you pop the hood and looks on top of the stuff under there (sorry, but no easy way to describe it)

P.S. after being in the single digits yesterday, today is 41 degrees. HEAT WAVE

Forget my post Steve, I thought you were looking for your plug. [V] Silly me for trying to help a man huh!

12-21-2004, 08:34 AM
Steve - don't count on them putting the heater plug in the same place. Mine is on the driver's side next to the fog light. Took me awhile to find it and of course I waited until it was COLD to look for it. Good Luck

Steve you started an interesting chain of events! First I checked the Dodge internet site and the specs for the 3500 Ram says ALL have engine block heaters as standard. Next I check the truck manual (now that's almost a first for me) and it said there should be a plug on the right hand side behind the headlamp. Then (in the cold!) I flip the hood and lo and behold there it is - hidden away with a neat little cover to disguise the little rascal.

Final (?) chapter - I can hear Diana on phone to our dealer asking them in no uncertain tones why they either don't have the time or don't have the gumption to explain these things to first time diesel owners. Glad I'm not on the other end of that conversation!

Would have been a good idea to plug in yesterday with the temperature (including windchill) at minus 37 celsius! Today is almost at freezing point - balmy warmth!

Sue, on the GMC if You pull the wire out of the loom a little the wire can be fed low and come out through the opening in the bumper.


12-21-2004, 02:09 PM
On my '03 it was on the passenger side, with plug tied up just behind the grill. After unstrapping it I could fish it out the grill and just let it hang slightly outside the grill for easy access.

This problem is a bit different (Sue, not so silly. Thanks for trying.) For '05 they say all have block heaters but the cords/plug are provided only for those delivered in certain states. We bought this one in Kansas, which is not listed as one to get the cord. It also said the rest of us have to buy the cord if we want to use the heater. I'm willing to do that if I figure out we really do have the heater. The selling dealer told me they don't think they have heaters unless ordered as an option. That I know was true for '04 and earlier. But I read about the '05s on Dieselmann's page, a highly respected source for Ford diesel information. I stopped at a Ford dealer this afternoon and the parts guy brought up a drawing showing where the heater would be. Unfortunately the picture is not very definitive other than it replaces one of the freeze plugs. It looked to me like it was near the flywheel which in this orientation would put it on the passenger side rear. But I'm not positive about that. Tonight's low is to be 13 with high tomorrow of 18 with windchills below zero. So I'll hold off on crawling under there again.

Thanks for the replies. If we get a decently tolerable day I'll crawl under there. When I looked before it's really hard to see anything under there. Lots of framework, cradles, and everything else they put in there these days. I probably will have to resort on the ol' feel around method to try to find it. If it's there I'll go get the cord.

Got out the manaul tonite. Apparently not all Dodges are equipped either. "The engine block heater cord is a factory installed option. If your vehicle is not equipped, heater cords are available from your authorized Mopar dealer" Seems kinda dumb to me.


Here's what it says to do in EXTREMELY COLD WEATHER-"In extremely cold weather below zero F (-18C) it may be beneficial to cycle the manifold heaters TWICE before attempting to start the engine. This can be accomplished by turning the ignition OFF and then back ON after the WAIT TO START light has gone off, but before the engine is started."

Also, the Dodge manual suggests plugging in below 32 degrees.

Stay warm everyone.....

I went to thedieselstop.com in the 6.0 section and did a search. The only thing I could find was the P/N number 5c32-6B018-AA.

Supposed to be for the 05 model.

12-21-2004, 03:24 PM
Steve, I bet if you called a Ford dealer they could tell you exactly where it is located. Just a thought.

12-21-2004, 03:57 PM
Steve seems to me that I read somewhere that it is located behind the filter on the pass. side. It can't be the oil filter since it's located on top.

12-22-2004, 03:09 AM
Found it Steve,,, neighbor has one of those things...couldn't find his either.

You can't see the frost plug... a very wide cross member covers the frost plug.

The heater plug is ty wrapped up behind the lower bumper. The truck next door has fog lights and tow hooks. It's between them.

That is on the passenger side level with th top of the licence plate holder, about 12 inces over.

You have to lay on your back, you can't get your fingers in easy and cut the ty wrap... you then have no more then 12 inches of cord to play with.

12-22-2004, 03:22 AM
Just found your photo Steve... right behind that verticle section of your bumper. The truck nex door has a tow hook out board and fog light inboard in the two holes. The plug was right between them.

12-22-2004, 09:12 AM
Wow, thanks everyone.

Gruffy, when Vicki gets home with the truck I'll look again. Supposedly mine was sold in a state where they don't provide the cord and I'd have to buy the cord (like Sue found out about her Dodge). But if the cord is only about a foot long then I'll look where you suggested and see if I can find where I would plug the cord into. I think it's really dumb to not supply the cord.

We're up to 14 degrees, a heat spell. The truck started just fine at 10F this morning but tomorrow it'll be 0F so we'll see how it starts then. I think I'll try the two-cycling of the glow plugs just for the extra heating time like someone else was talking about.

Thanks everyone.

12-22-2004, 11:32 AM
Great news Steve... if the cord is not installed, all you have to do is remove the motor mounts and tip the engine to the right. After you do that it will be a 50/50 chance you can get your hand in there and plug in a cord. There is a cross member about 12 inches wide in the way.

The truck we worked on was sold in Mississippi ... so... I hope you have the cord. If you can't find it, let me know and I'll get some photos posted for you.

12-22-2004, 03:06 PM
hi, the block heater was option 41H, you might check your original manifest to see if it had one installed. they were standard in Arkansas, Colorado, Iowa, Maine, Minn., Montana, North Dakota, South Dakota, Wisconsin & Wyoming ...

12-23-2004, 12:15 PM
Grey-ghost, is that for the Ford? If so, I'll check that (sticker's out in the truck and, of course, it's 12F right now so I'm not real anxious to go find it. Or to crawl underneath. There will be a warmer day. I hope.

Gruffy, I've seen that cross member and figured if it's there then that's where it is. Come a warmer day I'll do some more searching. I had to run some errands today at 5 degrees F. Used the double cycle of the glow plugs. It started right up. Ran a little rough for a few seconds then smoothed out. Sure would like to find out if it has the heater though. We bought it in Kansas so it won't have the cord but I can buy that from Ford but want to make sure it has the heater first.

12-23-2004, 02:53 PM
Like I said, if you have to buy the cord....better make a deal on "installed"...it sure doesn't look do-able at home.

12-24-2004, 10:18 AM
I think you're right about that, Gruffy.

Temperature hit 22F (but wind chill must be around zero) so I climbed into the insulated coveralls, pulled on my old coat and gloves, grabbed the flashlight and went exploring under the beast. There's definitely not a cord. I don't think there's a block heater but if there is it's in the area I can no way see into. I tried feeling around up there but didn't feel anything like I'd expect to find, although I really don't know what it would feel like anyhow. I may try emailing Ford customer service and see what they have to say.

12-24-2004, 11:03 AM
It's dark and spitting rain right now but I'll try to get a photo up tomorrow.... I wouldn't want to get run over by a riendeer while laying under the neighbors truck.

12-24-2004, 03:23 PM

Read here...great site for your truck if you are not a member and haven't been over there...but they are discussing your issue now...

Heck, I own a V-10 and I "partake" daily!


12-26-2004, 07:20 AM
Gruffy, thanks.I'll check it out. I am a member but rarely have time to go there. Will do so.

12-26-2004, 09:09 AM
Gruffy, thanks for the tip to check TheDieselStop. With information from there I found it. I found a post saying it's above the starter, which significantly limited the search area.

If anyone else is looking for the block heater on the '05 6.0PSD, crank the wheels all the say to the left, crawl up into the wheel well on the right front, shine a light through the opening in the wheel well liner. You'll see it there with two male prongs. It's easy to see now that I know where to look. I still have to buy the cord. The dealer wants $57 and tax for it, which is the same price someone on TheDieselStop was quoted.

Thanks again. This week I'll go get the cord.

Yeah, Steve!! You go!!

12-26-2004, 02:13 PM
Steve: I sure learn a lot watching your posts on all those "unusual" questions and problems you encounter.

A short add-on, primarily for the Cummings/Dodge users..We used the block heater last year a few times in cold weather and noted that it (1.) Allowed the mainfold heaters to do a "short cycle" instead of a long cycle before the "Wait to Start" light went out and (2.) gave much smoother initial operation and a very short warm up time for defrost or heater use and (3.) most important..kept the zero oil pressure time WAY down.

I have to believe that use below 32F will really help in both the short and long term... especially when you consider the zero oil pressure situation and the long cycle, double duty for the mainifold heaters. In less "geeky" terms, in really cold weather, it is nice to know it will start easily the first time, and get warm quick when it is really important for it to do so.


12-28-2004, 03:34 AM
Steve -

This post and the other one caused me to dig out the cord on my Silverado (which I also didn't know it even had). One thing I found surprising is that Glenn didn't stop in to quote the temperature in Florida. Glen, hope you're out there and snug and warm.

12-28-2004, 05:49 AM
PJ, I agree with you it's a great thing to have in cold weather. My goal is to someday never be in that kind of weather but until we can coerce the kids to move....

Ron, glad you found yours. On our '03 it was also tie-wrapped up in a place hard to see but at least the cord was there. On this one I have to buy the cord just because I bought in a state Ford decided wouldn't need the heater. I think I will email a complaint about that. Maybe if enough people complain they'll change that next time.

01-06-2005, 05:08 PM

I have an '03 Ford 250 with the 7.3 PSD. Over Christmas I mentioned to my father-in-law that during a recent cold spell the truck was really slow to turn over. My father-in-law says, "Why don't you use the block heater?" Boy did I feel stupid. I've had this truck since 2002 and had no idea it had a block heater. We went outside with a flash light and the cord was right beside the driver side fog lamp.[:I] Now that I think back, we haven't really had a cold winter here above Atlanta for a couple of years, so I haven't needed a block heater until now. Well, th-thats my story and I'm stickin' to it...:D

Steve, I went on the GMC website to spec a new truck and the block heater cord is now a $35 option. Kinda rediculous to me but then again in many applications a spare tire is an option.


01-09-2005, 04:22 AM
I guess they figure not everyone will want/need the heater and cord. It's probably cheaper to install the heater in all of them and just leave out the cord. I emailed Ford about this, asking why I didn't get a cord. They called me but we were on the road and didn't hear the call. I have a message to call them and will do so when we arrive in Savannah. Monday we'll be on the road again so won't try to call then.

01-21-2005, 08:35 AM
Folks: I have a 2000F250 with the 7.3diesel. the block heater for mine is located just above the oil filter. the ford mechanic showed me a 2004 diesel and it was there also. it is just a simple heating element that goes into the water inside of the engine block. it has an orange cord coming from it that leads to the front grill. there should be a plug cover on the end of the cord. jack

01-21-2005, 01:03 PM
Jackswing, our '05 has the place on the block above the starter to plug in the cord but there's no cord there. I'll have to break down and buy the cord before next winter. Looks like it plugs in and there must be a nut that then threads to the block fitting as I see threads there.

01-21-2005, 01:42 PM
All this talk of engine block heaters got my interest peaked so I went on a quest to find mine. I purchased my F350 last year (used from dealer) and was told it had an engine block heater. I made a cursory search at the time of purchase but never found it. I keep the truck in the garage and drive it about once a week so no real need for the heater. Well.....my quest was fruitful though I had to check the owners manual first and then poke around unit I finally found it. It was located behind the driver's side fog lamp accessable through a small opening beside the lamp. At least I know where it is now.

01-21-2005, 02:06 PM
Interesting, Theadamsfamily. Your 2002's is on the drivers side by the fog light. Our 2003's was on the passenger side by the fog light. As you said, it was well hidden. I missed it the first few times I looked and found it only when I crawled under. I then cut that tie and let it hang out next to the fog lamp.

01-22-2005, 07:00 AM
Steve, There are several threads on the web site www.thedieselstop.com, this site is dedicated to Ford diesel pick ups. I have an 04 with the 6.0, live and bought it in VA, the cord was nylon zip tied to the passenger side grill support, hard to get and find, once I clipped the zip tie, I was able to pull the cord down by the fog lights.
I can't imagine a service writer not knowing about this, maybe he used to work at Walmart :) Good luck and happy hunting

01-22-2005, 02:12 PM
Thanks, cv67cheng, but they changed things with the '05. Our '03 6.0 had it behind the grill like your '04 but for '05 they don't put in the cord unless you buy in certain designated states or you pay extra in the other states. Sure wish they hadn't done that but they did. I can see the heater connection point on the block above the starter. But no cord. :( Thanks for the tip anyhow.

01-28-2005, 06:56 AM
Was at a Ford dealer last night getting ready to order a '05' Super Duty and they said the engine block heater is a option for $35. It is not standard equipment.

01-28-2005, 07:49 AM
I looked and looked but could not find the cord. I see the heater above the oil filter but the cord still alludes me. Oh well, in Southern California I guess I really do not need it! [8D][8D]

01-28-2005, 10:31 AM
DCP, in reality, the cord is what you pay for when you get that option. The block heater is in all the .05 6.0's. I didn't pay for it, it's not listed on the standard or options on the sticker for ours, but the heater is there. Here's a link from Dieselmann's page where he lists all the tech bulletins from Ford.


Better yet, here's the quote from that page:

2005 Block Heater Option:
All 2005 F-Series and Excursions with the 6.0 PowerStroke have a block heater installed on the engine. However, the cord for the block heater must be ordered as an option (code 41H). The cord is installed on vehicles originally sold in the following states: Alaska, Colorado, Iowa, Maine, Minnesota, Missori, North and South Dakota, and Wyoming. Broadcast Message 1512, 3090.

When we bought this one we were parked in Missouri but bought in Kansas.

By the way, go with the $35 option if you're buying. Ford wants $57 for the cord over the parts counter.

Here's a picture of the block heater connector in our Ford. Sorry it's fuzzy, I just reached in there with the camera and snapped it.
