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
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.
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.
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
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.
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.
Now, can somebody tell me what's involved in loosening the a/c compressor to move it out of the way so I can get the block heater into the hole?
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.
