Just found out that my 2012 f250 block heater isn't working. Would not start with remote but thankfully she fired up using the key(barely it wouldn't even idle). It was -43c with wind chill last night. I tried 2 cords and 2 separate plugs and can't hear it kick in(telltale sizzle). My lovely wife is going to take it to the dealer this week but I just asking if I am possibly overlooking something simple here. I don't believe they are on a relay or anything so I'm thinking bad cord or heater itself. Truck started though so that's a good truck I my opinion.
What was the temp without wind? Just curious. While living in Alaska if the oil vicosity was thin enough I found I really didnt need a plug in for start up, it was mainly to be able to use the heater quicker. The diesel was a different situation altogether.
I can't hear mine also like my 99 but it is working, at those temps 4 hrs. plug in time should be enough.
Next time plug it in for at least two hrs. and feel with your hand for a warm spot where the cable goes in the engine.
I believe we were somewhere around -36 without the wind. I don't drive the truck everyday so I plugged it in for 2hrs before trying but I thought something was up when I couldn't hear the telltale sizzle start after a couple minutes. Someone asked about the block heater in general and yes they come std on vehicles in our climate here. The cord end is just clipped up inside the front bumper which sure beats having to dangle it out of the hood like the old days.
That makes 2 people saying they can't hear there block heater. Hmmm maybe they are weaker in these new trucks and silent. I don't know how to perform a amp draw test but that is probably exactly what the dealer will do.
I just googled how to test the block heater with I multi meter and its really easy so I will check it before sending it down to the dealer. We don't need them everyday just during extreme cold snaps. It would prob start anyways but it sure is easier on them when they're plugged in. Until your wife drives off with the cord lol. I have a cord with a really loose end that I use on her car, it is perfect, her block heater works and when she forgets and backs up it just falls out yet stays plugged in to the house.
I ended up crawling under the truck and I can hear it plus I can feel warmth when I reach up by the block heater. So I guess its working which is good I was just used to being able to hear it when its quiet outside. Thanks for the responses
Yep, -49 with the wind chill last weekend and even tho my truck was plugged in for a few hours it wouldn't start remotely and reluctantly started with the key. Leave it plugged in all night and no problem.
That is odd that you have issues using the remote start when it gets cold. It has been down in the -30's (-40's with the wind chill but that is of no consequence for an inanimate object like a truck) I have not had any issues with mine and my battery is half shot 450cca vs the rated 650 or so it is supposed to have. I haven't even plugged it in yet this winter.
