i just got my 1st diesel last weekend and its been a little weak on startup in the mornings, its suppose to get down to about 20*f tonite, so i plugged in the block heater, is it ok to leave it on all night? im going to get a timer tomorrow but just for tonite i was gonna leave it on all night if its not gonna hurt anything.

 

no it'll be fine to leave it plugged in, might be a good idea to check your batteries before it starts to get too cold and they leave ya stranded

 

3 hours on a timer is good enough. At those temps, anything longer is basically a waste of electricity. Might as well get the Heavy Duty type of timer.



Welcome to the site BTW,

 

yeah im gonna check them tomorrow at work, hope theyre fine bc it'd be expensive to replace 2 batteries
thanx for the welcome, ive enjoyed all the reading so far

 

 

i leave my block heater, battery blankets, oil pan heater and lower radiator hose heater plugged in all night the price of electricity is the last thing on my mind if my truck dont start

 

wow that sounds like a little overkill

 

I leave mine plugged in all night as well!

 

Battery Blankets in Idaho???? I would rethink that if I were you. Battery Blankets will boil your batteries dry unless the temperature is well below -40F. They will work ok if you dont plug them in.

How cold does it get there? I dont imagine it gets very cold by "cold" standards.

 

block heater? i dont think it even gets cold enough here in texas to make butter stiff.

if you hug your truck enough it will stay warm

and yes, i think its only smart to leave it plugged in all night. plug it in before bed time, than walk out and bust her off in the mornin'
