Ridiculously long warm up time / heat

[joe308]

You think DC would have addressed this already. My 03 CTD takes for forever to warm up - longer even than my 94 did and it's not even below freezing yet! Had a 00 PSD and it had an exhaust divertor that went on automatically when temps were below 35 or so - improved warmup time greatly. Not sure if I buy into the excuse that all that steel needs time to get hot, as it cools off pretty darn fast on a cool day. If I make a bunch of short stops, turning het off for 30 minutes each time she never gets up to operating temp. Since it's auto no exhaust brake option. Is there any other cure for this?

your sig doesnt say where you live but im in NY and we have had some cool mornings. I try to keep my truck in the garage only because the acid rain around here kills paint and my truck is black. anyway i get heat in just a few miles but it takes a while for my guage to hit normal operating temp. If you are letting it idle and expect it to warm up its not really gonna happen you need to drive it but take it easy till it starts to get warm.

I wonder if you could have a thermostat stuck open or some kind of electronic glitch. Mine heats pretty fast--As well as my 94 which is slightly better than the wife's car (bonneville)

All four of mine from '95 to '03 have taken up to 12 miles to warm up even down here in central Florida where we consider 40*F to be a blizzard.

Yes they do cool down quick. My engine doesn't have very much insulation on it.

About 2 or 3 miles I have heat. (and the first 1/2 mile is all downhill)

My '03 warms up the same as my 2001 and '98. 5s did. I start getting warmth in about 2 miles but it hasn't been that cold yet.

Same here.

well i'm all new to this stuff but i also noticed that mine takes abit to warm up and it does cool off fast. It's been in the high 30's in ct lately and i'll turn it on roughly 5 min b-4 i leave and it will take a good 1-2 miles for the gauge to even start to move. I'm wonder when it's gets into the teens around here how long it takes to get warmed up. oh sorry i have a 2000

Mine seems to warm a lot faster than any gasser I've had. It's also a lot warmer (heater wise) than the Pete I was driving last fall.

The way I understand it, the diesel takes longer to warm up because it is so efficient. The heat from the fuel gets turned into rotational energy (power) more efficiently than a gas motor. So there is less heat to be absorbed into the engine mass. Don't forget there is a lot more mass to heat in the CTD than a gas.

I think the CTD does pretty well. By comparison, my '99 Ford warms up the fastest, the '03 Dodges second and the Durapooch trucks by far take the longest to produce ANY heat. The D-max comes from the factory with a cold front, covers the grille and entire front bumper. It still takes 15 miles of 70 mph freeway driving to warm it up, both my '01 and my '03 are like that. The Ford PSD is HOT in about 2-3 miles, the Dodge in 5-6.



The comment about efficiency is right on. Also, you have to burn some fuel in a diesel to warm it up, it takes forever at idle. Driving is the quickest way to producing some heat.

I have to use the cardboard trick with a 8" square hole in the middle or mine takes forever to warm up in the winter. With the cardboard it takes a couple of miles.

It was 27* here this am.



I idled the truck for about a minute and put the fan on medium speed with just the top vents in use. I started to get some heat in about a mile and by the time I reached I-84(about 3 miles) I was getting plenty of heat to crank the fan all the way to high, still just using the top vents. When the cab started to warm up real nice I split the heat to get some on my feet and left it there until it was toasty (hot) in the cab. I then switched to the feet only position and low on the fan.



FWIW, I find the cab heats up much faster when you use the top vents. .



We got just enough snow to cover the lawn and vehicles yesterday, it mostly melted but there was plenty of black ice and accidents this morning . Happy Winter .

It was 29 at my house this morning, the truck had not been run in two days. Started it, let it idle for about 5 minutes, the high idle kicked in which is pretty neat, had heat in about 2 miles. This truck heats up fast, however the temp guage does not move till about 5 miles into my ride.

 

[PaulG]

i do get some heat fairly quick. i hit my remote starter and let it idle for roughly 5 min b-4 i take off and go easy with it for about 1-2 miles then the gauge moves a little.

Yup long cold winter ahead if this is any sign 30 deg here in manchester was towing a 28ft trailer (5,000lbs empty) this morning truck seemed to warm up abit faster for some reason

 

[MMeier]

Heat, I don't need no stinkin' heat , hell it's still 90-95 degrees out here and about 65-70 in the morning on the way to work!!!!

 

[joe308]

Ahhh, now if your A/C took 25 minutes to get cold you might not be laughing... .

 

[MMeier]

Damn right !!!!!

Block Heater

My '03 seems to heat up much faster than my '95 did. Here is one more suggestion. Plug your block heater in at night to a timer. Have it turn on about 30-45 minutes before you plan to start it in the morning. Your heater should blow warm air much sooner. Maybe if you get her good and warm before your first stop, she'll keep that heat through all those stops and starts?

i was actually thinking of buying the grill inserts to block off a few of the spots it's only about $60 for the kit and then you can remove any of the holes you want to give you the balance you need. The will help with the 20 deg. nights in november here in ct anything below 20-15 deg i'm going to put a timer on the truck and have the block heater start a few hours b-4 i go to work at 5:30am.
