they fire under compression...the heater does nothing except let it start easier....minor heat....it takes 15 min to warm up and warm up trans a little....if any....they are still ice cold for like a mile or 2....bad for motor to do this and shut down...ok to do this and run em....they need heat!

I ALWAYS run my truck before driving it anyway,to get the trans warm,I have a problematic trans in mine since it is old school truck,(94 7.3 turbo)I do whatever it takes to keep it safe.

Truth is you have to run them to warm them up. Even big rigs don't warm up much idleing. One mile runs are not enough to burn off condensation. I agree that you should buy a daily beater.

ID WALK!1 MILE =4 LAPS AROUND A HIGH SCHOOL TRACK OR 25 MIN TOPS!SAVE YOUR MONEY ON THE BEATER FOR GAS MONEY IN THE BOAT! BY THE TIME YOU START THE TRUCK AND WARM IT UP YOULL BE AT WORK!

If you lived in fla not mi you'd be o/k . I also live in Mi and let my truck warm about 1 or 2 minutes before heading to work 18 miles,the first 2 or 3 miles truck does not warm up. Sure,with the new LBZ you could let it high idle for 15 or 20 minutes everday but the amount of fuel you would waste and time pizzing around wouldn't be worth it. I personally would NOT do it,you would never warm it up enough just going back and forth to work. I avoid driving mine (to work) unless the roads are snow covered because it takes to long to thaw windshield and warm it up. If you do buy one get the heated leather seats so it won't be as miserable in the cold,Smitty

I agree 100%,Smitty

I have had 4 diesel trucks over the last 8 yrs and have had good luck with them mechanically. (except the '03 Ford 6.0) Every one of them has been taken care of meticulously. I always let the truck run for 5-10 minutes before I drive it (when cold) and at least a few minutes even when already warmed up. I also let it run for 3-5 minutes after driving it. After towing, I let it cool down for minumum 10-15 minutes.

This is imperative to let the truck warm up and cool down after use. This can lengthen the life of your diesel significantly. Just imagine trying to just have sex without the girl excited (or wet) and jamming yourself into her....ouch!! Same idea with the truck, these trucks weigh like 6,500lbs and they can just start or run "dry" and not warmed up.

If you notice, most diesel owners run trucks less than 5 years old. Most people running diesels have money, so if you just trade it in every 2-4 years (like most) you won't have to worry about any damage. Then you can tow your boat , have a grocery getter, and drive to work every day, all in one vehicle..

That would be a yuppie...

I'll have a 2 mile commute to work in about 2 months.



Can't wait.
