Dodge Dakota, Truck
Aug 18, 2002 (3:23 am)
I dont think the 3.7 will be available this year. I just saw a 2003 extra cab with a 3.9L and was disappointed. I was hoping to see a new light weight frame and possible a new transmission but no dice. Looks like Dodge has decided to use up all 3.9 inventory on the dakota and will not make any major changes for 2003. I for one am very disappointed as I was hoping to see some improvements.
#4286 of 5120 2002 QC Update
Aug 18, 2002 (6:02 pm)
Just completed a 2 week vacation with my 02 QC (4.7/auto/3.92/4x4/no mods) covering just over 2000 miles. Overall the truck is a surprisingly comfortable long distance driving vehicle. This is the first vehicle that I've driven where my rear-end isn't painfully sore after driving 12 hours. I wasn't expecting the Dak's seats to be that comfortable. The mileage ran between 15.6-16.0 (MPG) driving on the highway at 70-75 MPH with the AC on. The best mileage (17.3 MPG)was seen on a 100 mile section of 2-lane road where the average speed was 55-60 MPH. The AC performed well on the humid 85-90 deg days. Once the cab was cool, the lowest fan setting was all that was needed to keep cool. I have done the AC line insulation mod. On the return trip I had a 2400 lb trailer in tow. The 4.7/auto/3.92 did a fine job through the hills of western and central NY. Maintaining 70 MPH up the steepest hills only required part throttle in 3rd gear. If I was willing to let the speed drop to 60-65 MPH, quite often the tranny would stay in 4th gear while going up most hills. The only time full throttle was required was for rapid acceleration. The trucks brakes seemed up to the task of bringing the combined 7500+ lb combined weight to a stop within a reasonable distance. My only complaint after this trip is that the driver's side rearview mirror vibrates at speeds greater than 70 MPH. The only problem encountered is that the passenger side power window switch stopped raising the window on our last day out. It can only be raised from the switch on the driver's side. Time to visit the dealer for the first failure in 12K+ miles.

I just got back from a 1000+ mile trip and my best tankful was 24.9 MPG.
(overall was 18.503 MPG)
I attribute this MPG to the addition of REDLINE synthetic lube in xfer case, xmission and both axles just before the trip. It shifts much better too
(2000, 4.7L, 4X4, 3.55, NV3500 tranny)
#4288 of 5120 bpeebles on mileage and such..

all i can say is WHOO HOO for 24.9!!!! While I have the auto and 4X2 I see something like 19 for city/highway combo commuting driving.. sounds like a monitoring session is inorder to get a baseline. At 58,000 and TLC hardware,tire and fluid maintennance.. I am quite happy with performance...

I also have to say that the 24.9 MPG was with high octane fuel and my wife driving. (65MPH for hours and hours)
Both of these contribute to better MPG.
#4290 of 5120 High Octane?
Aug 20, 2002 (5:07 pm)
hmm.. I thought the 4.7 drank 87 or so per the "manual" .. whats the benefit of higher? should i go to mid or higher? How does this affect the 4.7?

bpeebles...I read what you wrote "I also have to say that the 24.9 MPG was with high octane fuel and my ""WIFE"" driving. (65MPH for hours and hours)"!!! HOW COULD YOU ??!! unless an absolute emergency...especially with the manual trans..Either she is properly trained (by you of course) or you had a few beverages/hangover..I could understand that..
My wife hasn't even sat in the drivers seat!!..anyway...all in fun..Great mileage..I just calculated my 3rd tank of gas mileage after the flowmaster install, and was 17.62 MPG. 3 tankfuls showing
same increase in mpg! take care, Ger.
#4292 of 5120 AC Mod, Octane Level, Crazy Ash Tray?!?!?!?!?
Aug 21, 2002 (11:52 am)
-I keep reading about an AC line modification to make it cooler in the cabin. What is it? How do you do it? What's the cost?
-Does anyone have an answer to "ahasher"'s question about fuel octane level in the 4.7?
-I drive a 2001 SLT extended cab, 4.7L, auto trns. Have had it for just over a year with no problems except the ash tray (pops open every time I close a door or hit a bump). Installed an Airaid intake and noticed a 2 MPG improvment in city driving (11 to 13 MPG). Altitude plays a big part, as I'm stationed in Colorado.
-Thanks in advance for any replys/suggestions!
#4293 of 5120 ready10 ashtray

My ashtray did that too. They had the part on order for weeks and finally fixed it.

The main reason I chose to use Hi-octane fuel during my extended trip was to reduce engine-damaging pinging/knocking. The outside temps were over 90 with high humidity and the AC was on the whole time. We were travelling the rolling hills of SW Pa. for most of the week.
A side-benifet to using the higher-grade fuel is that it contains detergants and other cleaners to de-gum the injectors. (you get what you pay for)
The higher flash-point of the hi-octane fuel can contribute to better MPG under some conditions.
