Hey Guys,<br> On a 25 degree mornning, how long do you warm up your engine in the morning before you go to work? Thanks. ;D

 

Long enough to let the oil pressure build up and then roll on. I take it easy for about five miles or so then go for it.

 

Same as Diesel Dude. I let the oil pressure build up and then ease off at an idle to the end of my driveway (about 50 yards). Then easy to third gear staying at about 15 rpms to the end of my street. Then I change gears at 1800 and ease up to speed for about 5 miles and by then she's starting to show on the gauge.

 

Ditto to the above unless I have to scrape windows free of ice and snow I then take my custom high idle stick and jam it between the seat and go pedal, bring the rpm's up above 1000 and leave it until I am done. I take it easy until the temp starts to register and then gradually bring he up to speed.

 

Same as the other guys, except the '03 has a built in high idle. The big thing to remember is to take it really easy for the first few miles to allow the transmission and rear end fluids to warm up as well. A good way to guage it is that if you start driving when your oil pressure come up, and keep the heavy pressure off all of the running gear until the engine temp guage moves up a needle width or more, you'll save many miles on transmission and rear end repairs.

 

I plug it in every night on a timer. Runs for about 3 hours before I leave. Let the oil pressure build up (I also shift it into neutral and let the tranny fluid run around a bit!), and i'm outta' there! ;D I'm usually rolling in about a minute or two...<br><br>Tony

 

Here is my theory. <br><br>This is my starting procedure for cold mornings.<br><br>I'll start my truck, let it idle for a few a minute to let the oil get circulating. Then I place it in nuetral (auto tranny) to let the tranny fluid circulate.<br>I then use a high idle stick to set the rpms at 1200. I will let it high idle until the heater grid stops cycling. <br>Once the heater grid stops cycling. Im off to work.<br>If its a really cold morning (below 20*), I'll let it high idle until I can feel heat coming out of the defroster. This usually takes about 4 to 5 minutes.<br>However, I should note that if I know its going to be a really cold night (below 20*) I'll plug it in.<br>Plugged in or not. I still let the truck warm up to where the heater grid no longer cycles.<br><br>Rich.

 

Rich, I follow the same procedure as you.
Do you leave the block heater plugged in while warming up at 1200rpm?
I do, and it will reduce warm-up times, and get the engine warmer faster.
Just don't forget to unplug B4 driving off
yeah....I've done it once this year already.

Luckily my rig fits in my garage. I still plug it in with a timer set for 3 hours before I leave for work. I like to have instant heat on those cold mornings. Just take it easy for the first few miles then it's game on!
