Engine block heater

[DJFZ71]

my buddy has a 2003 d/a cc and can't seem to find the engine block heater plug. is it standard with the dmax?

[BlackSilver]

Yes, it's standard on the DuraMax. The power cord is folded up and tie-wrapped down near the frame on the right hand side of the engine compartment. Can't remember exactly where it was attached, but browse around behind the plastic shrouding in the right front wheel well.

Unless it get extremely cold where you live you won't need it.I never used mine last year and it was in the -10 deg F several times.It will be hanging by the wheel well liner near the passenger side exhaust manifold.

I live in Charlotte NC. When it gets below freezing I plug my DA in. Although my truck will start like a champ even cold. I like the oil in the pan to be warmed up for that initial start-up, and a diesel takes several miles to warm the water in the radiator and heater core. Plugged in , I get heat right away.

I have a quick question on the plug......I have one on my 6.0L HD. Is it because of the plow package? And why is it you can only pulg it it for 4-6 hours before start time?

 

thanks

The cord is tied to the wiring harness that has the auxilary battery cables in it. It's below and just forward of the fuel filter on the passenger side of the engine. Look around in that area, and you should find it.

 

The cord will be too short unless you undo the end of the looming- removing some tape and pulling the cord of of the looming will get you an extra 12-16" of cord length.

 

Chev HD, you can plug the heater in for a month straight if you want. It'll do three things- waste energy ($$$), reduce the service life of the heater, and will eventually cook off some coolant. Otherwise, it shouldn't hurt anything. 4-6 hours is all that's usually necessary to heat the engine sufficiently. My truck usually gets plugged in for 8-12 hours at a crack when I'm at work.

Plugging it in when it is cold does more than assure starting, it is much better for the enging. If you were to start out real fast with a "cold" engine, you could blow a head gasket. (too much oil pressure)

I work in EMS and we keep the first-out ambulance plugged in all the time. Even in the summer, and in a heated garage.

Ditto on that .

All of our apparatus are plugged in (shoreline) all the time when parked in the station doesnt matter if its a 100 degree day or a 0 degree day

In fact two of our six trucks have two lines running to them the second being an air line

Its also handy to keep the batteries fully charged
