Engine NOT heating up

[jelag]

OK I give up.....



I have an 04, QC 4X4 3500 dually.....



Runs great and pulls a large service trailer really well... . it replaced my 01 3500... ...



Empty... . -20 outside..... pull the truck out of a warm garage and drive the 23 miles to work... . snow and ice and can't go much over 45 mph..... no load flat road... .



Temp gage only goes a tad over the 140 degree mark... and air temp out the heater is under 60 degrees... ... I tested the temp... .



Installed a nice piece of cardboard between the inter cooler and radiator... still no heat... .



At -5 or zero I have all the heat I want..... is the radiator that good that the water never heats up... ... my 01 doesn't do this...



Any thoughts or advice... .



Thanks , Jim

It may well be that good. In Fort Worth, Texas it dropped to the low 20s last night. At 11:00AM today I took off for work and 25 miles later (about 22 of that on the freeway) my engine had heated to about 160*, (with an outside temp of about 26*) but I had plenty of heat in the cab the last 10 miles or so. Glad I plugged that puppy in last night. When I went to lunch at 4:00PM the engine had cooled enough to require the 10 second grid heater cycle, which was the first time that has happened in the middle of the day.



I think the winter fronts all fit in front of the intercooler, so you might try that to get it to warm up quicker. Of course, this is also a good excuse to convince your wife that you need a heated garage...

Kind of the same deal here in Pasco, jelag. Truck didn't even come close to warming up yesterday. I wonder what it's like for the guys who live in areas where its "normal" to be -20F??

my truck is also real slow at heating up when cold. when i left for work this morning [now they have me on 0800-1600 ] my truck was plugged in and timer turned on the engine block heater at 5:00am and i left at 7:00am so it was on for ±2 hours. it started quick [grid cycle was real short] but before i had comfortable heat in the cab, i was at work, so 30 min later [25 kilometers away] so yeah, that's slow. now coming home from work, was the same thing too...



*i like this new quick reply thing... *

 

[jelag]

OK... . I haven't used a winter front... . because of the intercooler...



And my (hate to say this) Ford's (3) all come up to temperature within 10 miles... . including the F550... . all powerstrokes. .



Crunch -- The garage is warm... never freezes at night so it must be mid 30's or so..... that's as close as heated as it going to get. .



Someone from the cold part of the world please speak up. . do you use a winter front.....

-22 here for a few days, truck will not get up to temp until out on hwy givener. If you are towing even better. Cut a piece of carpet same size as rad & hang in front of it (put 8" hole in middle) 2 cable ties to hold it up. will not interfere with intercooler. Winter fronts are a waste of money as too much air comes in from down low

Cold Weather Use

I live in the Adirondack Mts of NY, just a little south of Canada. I dont have a lot of experience as I just bought my new 2003 HO/6 speed Dec 15, 2003. However, I have no problems with heat... . so far. I am 6 miles into town, all down hill so the engine is not really working hard. By the time I reach town, my temp is about 160/180, this is without using the block heater.



This morning I had to leave at 5am on a trip. The outside temp was near zero. I had the block heater plugged in and the

engine started with a short cycle of the grids. Same about 160/180 into the village. I was on the Interstate within 10 minutes of my home and by the first exit north ( about 8 miles) I was just a tad short of the 200 mark where it always runs. The heater would melt steel.



Temps down to 35 bellow are comman, and I have seen it down to 48 below. So far I have no complaints with heat.

Forgot to mention

No front cover to block/reduce air flow is used.

and all newer [sd body] 7. 3 psd's have that EBV in the turbine outlet elbow to assist in engine warm up

 

[DMyran]

I let mine idle all day yesterday due to all my running around town and it took some pretty hard driving to just get the temp gauge to even budge.

thats my two cents

I have no complaints about the heater, it is probably a little better than the ones on the other diesels I have had. I put the control between the floor and face until I feel comfortable, that helps keep the hands warm. I will never have another vehicle without heated seats, they are wonderful for this old man.

Mine seems to blow heat in about 3 or 4 miles. (first one is downhill) It does seem like the temperature must fluctuate depending on load, etc. because I've noticed if I'm cruising along comfortable heat setting and hit a hill, it gets a bit warmer. (sometimes have to turn it down or off)



I do wish the sliders for the temp control weren't quite so sensitve. (a little too touchy)



I'm also surprised and disapointed that there are no heat vents to the back seat. (or at least have the bun warmers back there too-- I wouldn't have ordered them, but I'm REALLY Liking those)

 

[Vaughn MacKenzie]

If it gets cold like this again I am covering the intercooler in hopes the engine intake will get warmer air. Certainly it gets cold enough to a point you don't want the intercooler taking away whatever precious heat the turbo kicks out. Doesn't make sense to have grid heaters warming it up when the intercooler is chilling it out. If you can get some warm air feeding to the intake it would certainly help combustion. If I live in Alaska, Montana or any other cold winter state I'd rig up something to send some warm air toward the air filter from the turbo area (not exhaust air but collected from around there like gassers did from the exhaust manifold).

A couple of days ago, it was about 15 degrees when I left work, I got onto the freeway doing 60mph (dry roads in King Co. ) and got up to about 180-190 when I got off the freeway in Puyallup. In Puyallup/South Hill it was icy and nasty, and people sliding all over the place the temp. was 10 degrees. I went down the road at about 30 mph stopping at a few lights. After ten miles the temp. had dropped to about 150. I pulled into the grocery store and called home to see if I needed to get anything, I let the truck idle for the 2 minute conversation and the temp dropped to where it was barely noticeable on the gauge.



I was wishing my winter fronts were on and not sitting in the garage.

It was 22 this morning, I had my scan tool plugged into the truck , also plugged truck in 2 hrs before leaving, after 15 miles coolant temp was 181

 

[jimnance]

It's been in the high twenties - low thirties here lately. Within 5 miles I'm up to 180F.



My '99 developed a problem warming up and when I removed the thermostat I found that it was broken. It's so easy to get to you might want to consider popping another one in just to see. If it doesn't help just clean the green stuff off and return it to the dealer.

 

[RGardner]

That is my question, shouldn't the thermostat keep the coolant from circulating till it reaches 190? It seems that these engines do take a long time to generate heat.

 

[jakprince]

You might try keeping it on recirculate to help keep from robbing all the heat from the engine especially when sitting there idling. The only trouble is the windows want to fog up sometimes.

They can get stuck open as well as shut. When they're stuck shut, you know it. (overheats) Stuck open and you have little or no heat. I think sometimes they get excessively slow to react which can make it tough to figure out what's going on.

You guys that complain about slow warm up must never have owned a first gen. This one warms up in 1/4 the time of my 93!
