ECO diesel engine block heater

From what I gather on the site--the Diesel already has the engine block heater built in and I just need to buy the cable? 67 and some change...I wasn't planning on needing the heater, so I didn't get it as an option..now Uncle Sam is sending me to the north!!

Does anyone have any clue how to install the engine block heater? Is it just the cable I need?

If so do you have pictures of a clean install for possible putting the plug on the underside mount of the vehicle or how its installed in the engine compartment...any help would be great!

Just had mine installed at the dealer and there are cables that go to the top of the strut towers (or whatever they are called) that I never noticed before. Also never noticed the glow plug module sticking up on the passenger side. I'm not sure if it's just new or it was wiped clean during the install.

I still don't see where the cord plugs in down from the top.

The first picture is the passenger side (for a left-hand drive vehicle) and the second is the left side.

OP, when you get the heater plug installed I highly recommend a timer to plug it into. I used to set the timer for about 90 minutes before I would leave for work in the morning on my other diesel. It could be snow and ice but you'll have a clear hood and windshield more than likely without wasting ridiculous energy.

Folks,
I have a 2014 GC Diesel Summit and it does have a Block Heater found pretty much as in the pictures from Milious, on the passenger side of the engine. It is clearly a 120V 3 prong cable with a plug cap on the end exactly as you can see in the picture.

When you unravel it, the cord is about 3 feet long which is probably not enough to route it out of the vehicle. What have other people done?
And where is the best place to route it?

I am thinking of buying an short extension cord to route it safely down behind the radiator using wire ties to keep it away from anything hot or rotating and then just out below the grill. Am I crazy?

I do not want to have to open the hood every cold morning.

BTW, do block heaters have to be on a timer? Can they be plugged in all night?

Thanks

I run mine out below the windshield by the base of the driver side wiper. I plug it in from the driver's side. Has the advantage that I see the cord when I get in and don't forget to unplug it.

I have mine plugged into a WeMo outlet. I generally turn it on 3 hours before I go somewhere. The WeMo is IFTTT compatible, so I can trigger it via a calendar entry. When I have a morning appt, I have it come on via a calendar event 3 hours in advance.

I work from home though, so my driving schedule is very erratic. When I worked a "9 to 5" having it on a daily timer worked very well. 3 hours was researched as the best compromise on our Prius, so I've simply stuck with that in the Jeep.

My dealer has just told me that the Block Heater can be left plugged in continuously without any damage; other than running up your power bill.

Unfortunately, I come and go at different times all day so a timer would not buy me anything.

As for routing the plug and cord, the idea of bringing it out just beside the left wiper motor is good. It can be held down so as not to ruin the paint. The rubber seal there is flexible enough and the idea of seeing it plugged in before I back out is really handy and safe.

On my Dodge Ram Cummins I wired the cord to a marinco 150 BBI plug installed in the front air dam. Has worked flawlessly for years....A very neat and easily accessible way to plug in. Am currently deciding the best way to incorporate in the CRD.

I took the windshield idea and did it without an extension on the passenger side. It works for me because i park my car with that side against the wall. As far as remembering to unplug it, tilt the mirror in or flip a wiper up. I attached some pics. Note that what appears to be a big hole for the cord in the second pic was simply lifting the gasket to demonstrate; you dont need any tools or modifications to do this (other than cutting one zip tie).

I bought a Kat after market cord on amazon. Can someone give me an idea on how to get this thing plugged into the heater. It looks impossible from the top. I dropped the skid plate ,and still could barely see the block heater.

Even if I was gumby, I don't think I could reach the block heater and hook it up. Pulled the right tire off and took the wheel well liner part way off and no opening except toward the front of the engine.

HELP. Wireman

Hi everyone,
Following is how I finally installed my block heater cord.
My 2014 Diesel Summit already had the heater and a short black cord.

1) Drill 3/8 hole through plastic wall near original cord.
2) Attach a 6' extension cord. Coil extra up and fasten with a wire tie.
3) Lay extension along and inside rubber splash guard under rear edge of hood.
4) Bring the plug out about 5" and tie it down with a cable guide and small self-tapping screw .

Cheers

I understand where the block heater is, I can barely see it with the skid plate off. My question is how do you go about getting you hand to it to plug the AC cord onto it? Thru to top looks impossible, underneath just about the same.

Anyone have any directions on how they did theirs. Wireman

There's another thread floating with some helpful hints. I did mine 2 weeks ago from underneath in OR1 height. I fit my hand up there and used needlenose after I had it started. I could really only use my fingers so it fatigued my hands quickly but I managed.

Not sure how people do it through fender well, I couldn't even see it through there.

Thanks techvudu, My JGC is also 4WD with no air ride suspension so that might make things more difficult.

Looking at Mopar parts online I noticed the Mopar cord has some sort of insulation toward the end that plugs into the block heater. Probably because it's close to the exhaust manifolds.

Is yours a Mopar or after market cord? If after market did you wrap any kind of heat protective material on it?

Thanks. Wireman

I bought the Mopar cord solely for that reason. I wanted the $5 of insulation they have installed. I might try jacking it up enough just to fit under. I think the lower it is the better the geometry for the suspension to let your hand up there.

Either way it's not too bad of a job. I put some electric grease on the connector to help slide it on. Routed up using the other cables which honestly with the zip ties already on it was worse than plugging in the connector. This weekend I'll be cutting the lower valence to surface mount the plug.
