Block heater question


mike rousseau

Recommended Posts

I've had a couple mornings this winter where my truck didnt start right away... Resulting in a dead battery after a couple seconds of turning over...

 

I don't drive it much... Pretty much on the weekend for ice fishing...

 

So I was thinking about trying the block heater...

 

I was wondering... How long do I plug it in for before I plan on starting the truck?

 

And do you guys think this will help...?

Yeah a few hours is fine.

When I moved to Yellowknife I parked my cube truck out front but didn't plug it in.

Overnight temps were in the mid -40's. It would only click when I tried to turn it over.

Plugged it in and 2 hours later it started fine. I do have battery blankets on all my vehicles as well. It makes them turn over like it's 70* outside. Warming the battery makes a big difference.

I don't bother to plug in until average lows are below -15C. I could wait until -20C but the extra wear on the engine is not worth the electricity savings. IMHO

..and Ford thought I was nuts when I requested that they stop the nonsense of my truck turning on all the marker lights every time you open a door and the safety issue, for a women alone, of the interior lights coming on when you shut off the truck. All that kills the battery in a week when ice fishing and getting your helmut out of the truck each morning

Mike, it hasnt been cold enough to freeze your motor up bad enough to drain the battery like you describe. I started mine to go to work this morning after sitting 2 weeks in the back yard.Started first shot.

Maybe your battery is getting weakdunno.gif

Yeah, I hate that too Wayne. My car lights up like a Christmas tree every time I exit it. I don't notice it in the summer but in the winter I stand there freezing until everything shuts off, just in case it's human error. And I just replaced a one year old battery (under warranty) because of this silly power waste.

I had a block heater on my Chevette and my first Astro van, I kept both parked outside, it was nice to have almost instant heat.

 

The tractors at work all had them, diesels can be a challenge at times to start when the temps get real low. You could almost always tell the guys to lazy to plug their`s in, they were always running to the shop for help starting their tractors.

 

On my cars I would plug them in when I got home from work, no timer, I figured the cost of the electricity was balanced out by the cost of fuel waiting for the windows to defrost.

I don't know about Fords but GM has this brilliant idea that even though you have a block heater and you plug it in it WON'T turn on till the temp is -21 ,there is a temp sensor on the cord to keep you from wasting electricity.

Wow. Thats the first thing that I've ever heard of that Chevy does better that Ford. Unless it fails, which Chevy products often do. Then you're stuck with no block heater at all...

You can purchase an inline one you plug in between the outlet and car that does the same thing.

I'm putting my money on a weak battery. Sure, the block heater will help get it turning over,but its not going to help the weak battery get stronger.

 

I'd suggest load testing your battery before it lets you down on a real cold night.

I'd say address your battery/charging issues before going to the trouble of a block heater. We really haven't had the deep cold temps yet and a good battery would have cranked it over.

I'm having the same issue with my Suburban right now. Anywhere below -10 or sitting a couple days and no start. Jump it with the spare battery and it fires right up. When it gets a little warmer I'll pop the new battery in.

A block heater will help the engine start easier but it's main purpose is warming the engine and fluids. If your battery is that weak, it still might not start!

Mike , north over the train tracks on McConell ,when at the bottom of the over pass make the right , do the little jog there to the south and then east to Gerard st, turn north onto it , second last house on the left , drive straight in to the small shop , five night a week and all day saturday and all day sunday , he will take care of you no matter what you need , you will be impresed once your in the little shop , and dirt cheap , all you have to is drive in the drive way .

It's a ford and already has a block heater... Just never used it...

 

And the battery has more cranking amps then stock... I made sure to up the power a bit when I replaced the battery 2-3 years ago...

 

I'm really thinking when cold it takes a lot of power to start the v8... And if I'm not driving very far... The alternator can't keep up...

Battery ? quick load test , ground gable? quick cleaning and retighten , Starter drawing heavy ? quick test , second last house on the left , talk fishing while you watch............. lol . He had a heads up early this morning that there might be a chance , he has an eye open as he's installing a timing belt as we speak so another fisherman has a ride for tomorrow morning .

What about the button on my dash that allows the interior lights to not turn on
