Hello everyone. I'm new here and I'm looking for a little help. I recently bought a 2000 Dodge Durango Magnum with a 4.7 liter VIN N. I originally thought the motor was an easy find being that the Durango came with a 4.7 from 2000-2003.

HOWEVER when I contacted several salvage yards they claim that the 2000 model will only fit a 99-2000.... If this is the case, why wont the 01-03 work?

I'm tearing apart my motor now to see if its salvageable, but if all 2000-03 motors with fit I can locate them for cheap.

Thanks,
RJ

 

To my knowledge they misinformed you.

 

Sick Durango man /\ /\

Any second opinions on this?

 

The flywheel thing, or maybe not the flywheel. There is something that has to have the same number of teeth or something like that. Silly 4.7s.

Also, you were misinformed. There has NEVER been a 1999 4.7 Durango.

I believe for the most part 00-01s and then 02-03s are interchangeable with one another. With that said, those in the middle may have a version higher than the others during the transition. Stick with a 2000 4.7 and it won't matter.

i would try to find a 00 4.7, but you were sadly misinformed, dodge did not have the 4.7 in 99, they switched to it for the 00 model year, and there is a tone ring or something that changes from 16-32 tooth (i think) late in the 02 model year, but you CAN change out the ring on the new engine with the one on your old engine to make it work, its not a really simple job, but it IS possible

 

Interesting... I will have to call around and look for a 2001 model. It seems nearly impossible to locate a 2000 model 4.7 in my area for under 1500, however; the 01 is common for 700-1500 depending on millage. I wounder why the salvage yards (3 I have called) all say that the 2000 is a motor of its self?

I'm not sure I want to change over the tone ring, which would require me to break down the motor and voids any warranty that may come with it. So is there a way for me to determine the difference in a 16 or 32 tooth?

I'm going to tear down the motor and figure out where the knock is coming from. I'm thinking it has a spun rod bearing. Hopefully the damage is contained and I can salvage the motor and be on my way with a little machine work...

 

i dont know of any way to tell without tearing into the engine, but im sure someone will know if there is another way to tell

 

I'm not familar with "tone rings" so I'm going to assume it has to do with the crank shaft position? If not what difference does it make if everything bolts up and all sensors read normal?

 

i think it is the ring that one of the sensors read off of, but im not 100% sure as i have never had to replace my engine, there are guys on this site (dont think in this section) that have done it tho ill be damnd if i can remember their sns

 

I beleive that it is on the flywheel that you have to swap out. You simply exchange just that with your old motor. There really isn't much to it. Most of the 2000's were 16 tooth and the 2001+ went to 32 tooth.
