6.0 block heater

[Colossus]

One more thing-  I have my block heater cord on a timer- so it switches on at about 4 AM so by the time 6 AM or 7AM rolls around, its good to go.

so just plugging it in wont activate it ? have to have temp drop to freezing first ? . also once on can you hear it like I can on my 88 chevy diesel ?

Off the top of my head the temp has to drop to around 18*F, not 32*F

I can't speak to the 6.0, only the Duramax, but it does make a big difference when I plug it in.  The Diesel has "smart" glow plug technology, which means it starts up nicely at temps well below 0 without being plugged in, however- it still needs a good 3-4 min warm up time at those temps.  When I plug in the heater, which I believe is more of a coolant heater vs an actual block heater- there is definitely a a huge improvement in that the start up is easier- not labored, and the glow plugs barely light up-  maybe 1 second at the most vs 2-3 seconds for not being plugged in.  The engine idles smoothly and doesn't go into a elevated RPM (by about 300 RPM) warm up for a few minutes.  Often the coolant is warm enough that i can switch on defrost on the windshield and it is already going to work. 

True!

It's 0F... or -18C.

Leave defrost in the on setting as it will allow warm air to defrost windshield while the truck is off.

 

Not saying it will make a huge difference but a difference all the same.

I knew there was an 18 somewhere.

That makes them useless if you ask me...the ones i have used had high temp limits, they would heat at 100 degrees, and shut off about 140 degrees. I want it to heat when I plug it in...

Then don't use a factory one, add whatever you want and carry a code reader to clear the CEL you will get lol.

does the code matter?  i mean, does the ecm do anything differently when it gets the code?  if the only downside is a check engine light every winter, seems worth it to me.

Well your command start won't work number 1... otherwise not really no.

Ok.  I don't have remote start, but based on what I am trying to accomplish, I think a remote start is probably a better idea than a block heater.  I will get one installed.  We rarely get below 0.  I was thinking the block heater might help with startup wear, but from what I gather my chances of wearing out a 6.0 are next to nothing, with or without a block heater.

Lucky lol.  It's been 0 F or colder every morning for the last week or so.  But I park in a heated building and or just remote start it.  Old truck has the same cord end and still runs great with 200000 miles so I don't worry about it.

I had 3 6.0 HD trucks (Western NY).  Seen some cold temps.  No block heater.  No problems.  If its cold as all hell just let it run 7-15 minutes or so depending on temps with the heat on a low setting or off.  In Oklahoma?  I wouldn't be worried about a block heater at all IMO.  Canada?  Minnesota?  I'd want one.

 

Heck, my Colorado diesel has one and I haven't even used it yet.  I have the elevated idle set to on which raises the idle to 1000rpm below certain temperatures.  Its usually warmed enough for me in about 10 minutes, and only a couple minutes after that does it reach operating temp.
