i have a 2003 edge 3.0 auto that im wishing to do a 4.0 swap with. i have a few questions that i cant find anywhere on google for my situation

1: need 4.0 engine and trans correct?

2: what about the wiring harness?

3: what about the a/c and things like that?
 
ok dude look it up u say u havent found anything on google ur lying or else u are blind. and are u not all there or what the o thing about a 4.0 swap is to swap a 4.0 engine into ur truck so of course u need a 4.0 engine. oh wait never mind i think what u have to do is convert ur 3.0 to a 4.0 by adding a stick of dynomite to ur engine and light it and run away and there u have it an instant 4.0 swap in a matter of miniutes
 
Please watch it 509lifted. We're here to help others with questions about the projects they're looking to do. It's highly likely that google just doesn't know how to bring up the answers or even the locations in which he might find answers to his question.


I know almost nothing about the 3.0L and 4.0L, but to start, you will definitely need the motor and transmission. Sticks of dynamite will do you no good, in this case.

The wiring harnesses will probably be very similar, but a more v6 experienced person will have to chime in on that topic, as I cannot offer further comment.

The a/c system should be able to stay in place, untouched by the engine swap. You may have to disconnect it while you're swapping motors, but through all the years of rangers, the a/c systems occupied the same space, except, perhaps, for the mounting location of the compressor.



Lastly, try to be as exact as possible with the questions you ask. Those looking to help you on here may give vague answers that could get confusing since we might not understand exactly what you're wanting to know. Nevertheless, don't hesitate to ask us to explain something further, if you're still not 100% following our advice.

hey asshole, having a nice day? awesome. I was concerned about the transmission so I just added motor there since its a habit. have a nice day prick. by the way, google doesn't show up a lot of stuff about the 02-03 4.0 swaps but it shows up a lot for other years!
 
No need to reciprocate the harsh attitude. That's a good way to have yourself banned on here.


Now, just sit back and chill for a while until some others chime in on ways to further help you. There is also a search feature on this forum that will help you find answers to your questions, so long as you have some patience with it.

Just use the search funtion on our site. We have a lot of swap info there. A lot of members have swaped in a 4.0. Some should pop in and help out too.
 
In case google doesn't pull it up anymore check the tech library and do a search on this site. You will have to do some work searching but all the answers you have should be answered here already.

Some of us just get irritated when a newb asks these questions without doing some real digging to find answers. Almost every question anyone has is answered on this site if you take the time to look. Happy hunting

man not meaning to hurt ur feelings man i just see this all the time i havent been here the longest but im already tired of ppl asking the same questions when all u gotta do is do a search on here which is bassically google search
 
i have gotten a lot of answers from google and the tech library as well. my only problem is a lot of it is for 1998 and older models. im having a hard time finding stuff for 00-03 i have looked at the engine in an 03 4.0 and it appears to use mostly everything the same except motor and transmission and obviously ecu, only thing is i only have google pictures to go from. ill have to hurry up and wait to see if somebody can give me a better helping hand on the wiring situation, which is what im most worried about
 
Depending on how you want to do it you can use the donor to rewire everything or splice the wiring into the existing harness.

Find a wrecked donor that matches your truck as exactly as you can and take EVERYTHING, right down to the keys.

That will make it as painless as possible.

You know what I'm tired of? People that can't spell, punctuate, or locate the friggin' shift key on their keyboard.

+1, also, those people who know what a comma and period do, but cannot seem to figure out that they need to include them in typed speech.

I simply cannot follow what those people are talking about when there are no commas or periods to separate ideas and thought patterns.


Btw, props to Doorgunner for over-abusing periods and exclamation points. He keeps everything SUPER interesting! :icon_thumby:
 
hey shane u should really ask first lol some of my keys dont work and when they do they stick and wont stop untill i trun my computer off orelse i would punctuate and capitalize things that need to be

So you're telling me that the period key, comma key, and BOTH shift keys are non-functioning?

Interesting.......
