lets talk about Block Heaters and Glow Plugs

[coassist73]

So who here makes use of the block heater on the trucks?

How cold does it have to be for you to plug it in?

Do you plug in with the block cold or warm?


When was the last time your glow plugs were replaced or checked?

I usually plug it in before I might need the truck, and below about 25-30°. I am in the midst of working on the glowplug system, just put in the stancor relay and now need batteries and have the glowplugs in the garage ready if needed.

I never plug mine in, just let the gp do their job

In Denver I rarely plug them in. Nights typically are in the 20's and the glow plugs alone do the job. I will say that switching to Rotella T6 really made a difference in cold starts.

When staying up in the mountains I plug it in whenever possible. Usually this involves running about three extension cords out the window of a rental condo. It isn't always practical, but nice to have.

I always carry a bottle of ether, just in case.

if its way below freezing i will plug mine in overnight... especially if i plan to go somewhere early the next day... I remote start it from the house n jump in a nice warm cab

At this point my 99 wont even start if it's not on block heater when it's below 32F. Tomorrow I will test the plugs and what not. Since the truck is also slow on cranking Im going to pull the starter and swap it with a spare that I have.

It does have 2 brand new Red top batteries that tested good today.

Relay is getting replaced soon on mine. Going to check glow plugs and replace if necessary. I plug mine in warm or cold. And only when it's below -10*Celcius.

Right now tonight it's going to be -26*celcius here were I am. I'm sure the Truck will be glad to be plugged in

i plug it in once there is frost or just below freezing. not really needed but starts way easier. from what i have read on here, an oil change, new ficm and atlas 40 will solve that problem.

I saw this video on youtube awhile back and talking about block heaters jogged my memory.
The video is by Powerstrokehelp.com and is on better fuel economy. If you skip ahead about 3:50 min. that is where he talks about plugging in. Quite an interesting theory.
