Block Heater a must

Last 2 days its been -24/C or -11/F at night (thats not including wind chill). Even with a block heater my 09/JK has a rough time starting, but hey its does finally get going. Not my 06 RAM 1500 though, Its frozen solid (dead) no block heater in it. I hate winter when it get this cold

Same here, -32 this morning, mines plugged in everynight in my garage (which is partially heated) when it's -5 and colder. I'm on the FD, we get called out all hours of the day/night, and it's easier on it with temps this chilly!

I live in the Yukon. My first mod when I picked up the "new" 2007 JK this Dec was an oil pan heater. I'll plug the jeep in whenever it gets -20 or so... it started fine the one time I didn't plug in and left it off over the weekend at -30 (was surprised). But I try not to do that... figure I paid (or will have paid) 30K by the time it's done... might as well do what's possbile to assist the engine.

I remember my grnd dad used to drain the oil from the tractor and warm it up in the drain pan on top of the woodstove so he could plow the driveway and town roads. He would have traded a daughter for a plug in block heater!!

got Jeep got stuff, never enough of the right stuff tho

Am I in deep enough yet?

When I lived in the frozen north I fitted a little fuel burning heater unit to my truck - Webasto? - it heated the coolant and ran the interior fans on a timer switch without requiring any external electrical power. So not only did it heat the block, but also the cabin.

The feeling you got when you came outside in the morning, watched your neighbours scraping ice off their windshields and just climbed into a nice, preheated vehicle was priceless.

I have yet to plug in my 08' it gets parked on the drive and starts regardless of the temp. we had a 3 week spell in december where it didn't get above -30 and dipped below -45 and actually hit -51 over night. I use synthetic oil which makes a huge diffrence, and keep an eye on the batt.

Even with synthetic oil that can't be great for the engine. My buddy did that last year during our 3 week -45c stretch... And while his mustang started every time, it didn't always make the nicest noises...

Actually unless you use a forced air heating unit to warm the entire engine compartment, your going to do the same damage with or without a block heater. A block heater dosn't keep the Batt from freezing, nor does it keep the steering pump, alternator, trans, diff, ecm etc! from freezing! At least with full synth oil you got your bearings lube at start up, and full oil flow at -45.

A block heater should do a reasonable job of taking the chill off other engine bay components - the key difference is that the damage to the engine starts the moment you turn the key, regardless of anything you might do. At least you can be gentle on the trans, diff, etc until they get a little heat into them.

Oil on top of a wood stove. That's not dangerous is it?

Danger was just a part of life back in the day.

A block heater will keep the engine from freezing. It does not actually warm it up - at least not at -30 temps... The other parts are still frozen. But for me, I know my oil is flowing properly. Maybe it doesn't make that much of a difference... but the electrical cost isn't that much... the peace of mind knowing I'm doing what I can to attempt to prolong the engine life is okay for me.

Heat is a different set of problems - see the photo of my dash earlier in the thread. I've had to relocate the battery out of the engine bay as I had problems with it boiling on very hot days!

Check out the bulges in the top of the battery casing!
