if anyone can help me out it would appreciated, where is the control for the rapid heat option located. I have the dual climate control in the dash, I know I ordered this option because its listed as 41A on the order.

 

I believe it should automatically turn on/work when you turn on the heat.

 

Yes, I believe it is automatic. I have it too for some reason, but there are no controls for it.

 

Yep, it's an automatic thing, turn on the heat and off she goes. When the engine gets to temp, it automatically shuts off.

On a cold morning, put your hand over the vent and feel the warm air.

 

I second what mattebury said. I have it on mine, and it woks seamlessly automatically without input required from you. Just set your temp, and it will turn on automatically if required, and when the engine is producing enough heat, it will shut it off. On cool mornings (34 deg) it is already blowing hot air before I get to the end of the block, and I don't usually run the engine to "warm" the truck up for longer than a few minutes. Once it's cold enough to have to plug it in, I'll idle it for longer.

 

A bit of a thread highjack... how cold do you reckon it has to be to plug it in. This is my first diesel, so no prior experience!

 

Probably right aound the 0 mark F or -20 C. Wouldn't hurt to plug in sooner. if it doesn't start at those temps ????

 

According to my owners manual, page 234, you aren't supposed to have to use the block heater until the temperature drops below -10 F (-23 C). Which was when I was planning on using, when the over night temps reach -15 C. There might be something different in the diesel supplement manual, I'll have to look.

 

Im new to this whole cold climate thing (moved to OH from AR) I hate starting my diesels up in this cold weather. What does it hurt to run a block heater when its not that cold outside by OH standards??? Ive never had to use them before, I guess I will have to get the whole thing figured out pretty soon....

 

It won't hurt a thing, other than a little higher electricity bill. I would recommend getting a decent quality outdoor timer, and set it to come on about 4 hours before you plan on starting the vehicle. Running the block heater for longer than 3 - 4 hours won't make it any easier to start and just uses more power. The power cord for your heater is by the passenger side tow hook.

 

Thanks. I'm in Colorado (Denver area) and it is rarely as cold as mentioned here, so I doubt I'll be plugging it in regularly.
