chidychi Wow.
It's Christmas already.
I can't believe I didn't see that before.
My Canadian JK has the block heater and I had no idea.
That made my day.

Yes. The heater cord should be tucked between the ECM and the ABS module or I have seen them tucked on the driver's side of the engine with the other harnesses.

Have to release tension on the belt tensioner (new fangled design I haven't figured out yet) and remove the belt from the compressor pulley. Then remove the 4 mounting bolts. 2 on top and two on the bottom. The bolts go horizontal into the block.

Peter T Mine came pre installed. Drivers side tucked in the front left corner. Just happen to find it while doing the blinker side marker light mod.

Wrong location for block heater

I got this same image from the dealer with the block heater for my 12 JKU, but found that it's incorrect. The block heater actually goes on the driver side of the engine under the a/c compressor.

redrockman This model of heater slips into a dry well in the side of the block and plugs into a 120 volt wall outlet via a cord attached to it exiting through the grille. The heater core heats the block metal and everything around it, mainly the engine coolant, and eventually the oil. This helps the engine turn over easier and gives the owner a faster warm-up in cold weather. It is a nice thing to have in cold winter areas.

ksdindy Just curious, but what exactly does the block heater do and why is it a good idea to have one?

Dumb question coming from a Jeep newbie and a mechanical idiot, I know, but just curious.
03-27-2012 04:59 PM
redrockman That is a big yes on that one. I surely would have if I had ordered. There is a well for it, which eliminates draining coolant and popping a freeze plug, but I think it is behind the A/C compressor.

glowingghoul This is one of those options that's worth the $30 or so dollars it costs when ordering from the factory, even if it's "just in case I move to Maine".

redrockman Went to install the heater today and the block well I thought it went in doesn't match the size of the heater barrel the dealer got me. Can someone tell me the approximate location of the block heater in the 3.6. Thanks

themoneypit We aim to please, your welcome
03-14-2012 10:52 PM
redrockman Thank you to themoneypit! That is exactly what I need. Wow, the part number and everything. This is indeed the dry well heater style. There is no freeze plug removal needed for the install. It slides into a well on the side of the block and it looks like a small screw holds it in place. Thanks a bunch.

SilverSport Have you considered a pad heater for the bottom of the oil pan?
03-14-2012 08:56 PM
themoneypit http://www.mopar.com/jeep/wrangler-u...hop/336759/77/. Don't know if this is what your looking for.

redrockman Went to dealership today and talked with a parts dept guy. He looked at the computer and some book, then came back to the counter and said by using my VIN and the year 2012 he could not find a part number for the block heater. I told him they make it because it can be ordered and there are vehicles out there with them installed. He didn't seem to give a hoot one way or another. That was the end of my visit with the parts guy. No one on here must have a block heater installed on a 2012, so I will pursue this again in 6 months when there are more 2012's on the road.
03-14-2012 09:45 AM
redrockman I guess I'll give the Parts Dept a call. They will tell me the immersion block plug type because they probably never heard of the dry well type, which the 3.6's come with..

2012 JKU 3.6 Block Heater question

What type of block heater goes in a 3.6 wrangler? I was looking around and the 3.6 Pentastar engines in cars takes a dry well type block heater which is simple to install. Does the wrangler use a freeze plug type yet. or will the dry well type work on the block since the 3.6 is using the same block? A part number would be great. Thanks
