Assuming that I would never have a heated garage, I thought it necessary to keep my Jeep nice and warm on cold winter nights with a block heater. You can buy these from almost every magazine for under $40. I bought mine from the Jeep Service/Parts Center at my local dealer. $35 gets you one immersion heater complete with a short cord and zip ties to tie the cord off so it doesn't get destroyed under your Jeep.

The instructions seem simple enough until you realize what you're supposed to do. It says to tap out the forward-most freeze plug on the driver side of the engine. This would be easy if the engine were, say, sitting on your kitchen table. If anyone has followed the instructions, and actually attempted to get that plug out please email me. I opted for the second from the rear on the driver side. What's the difference? I think they wrote that so they could charge you $89 plus tax to put it in, on top of the $35 for the block heater.

Anyway, the instructions say to drain the coolant. You don't have to. I drained only what fell out when I popped the plug out. Get a big plastic catch under the hole to collect the coolant. Take a regular slotted screwdriver, placing it at the top of the inner lip of the freeze plug. My brother engineered a special three foot long screwdriver for me, so I didn't have to get too wet. Get as far away from the path of the green monster that will flow out the second the plug is free. Give it a good whack or two, and wait for the coolant to stop flowing. The rest is easy. Grab the plug, which is still in the hole, with a pliers. Do not leave it in there, or let it fall inside. Most likely nothing would happen if you did, but why would you leave spare parts inside your engine.

The heater plug is held inside the hole with a device similar to a drywall anchor. A butterfly spring nut is spun onto the heater's center screw, and once it is inside, tightening down the screw draws the butterfly spring open and closer to the hole. When tightened, the heater plug is leak free with the supplied O-ring. After that, refill the radiator, start her up, and wait for the possible guzzling from the radiator. In which case, you may need to fill it again. Total time to complete this job will be around one hour. Most of that is making a 3 foot long screwdriver from scrap metal, and waiting for the coolant to drain. Tools needed: Slotted Screwdriver and Pliers.

Mopar only supplies you with a 3 foot cable. I recommend going to Home Depot and buying some extension cord, and waterproof connectors and extend your cable to the front grille. That way you won't have to raise the hood every time you plug in.
