2000 4.0 in a '94

[Rodinator]

Anyone know if a 4.0L from a 2000 explorer will fit in a 94 model (has 4spd AUTO TRANS)? I have access to a low mileage wrecked 2000 explorer, so the computer, harnesses, etc are available if needed. Any advice appreciated......

Thanks,
Rod

At the risk of sounding frisky, I gotta say that you can put anything anywhere you want as long as the hammer is big enough. I can't speak for transmission bolt pattern since the A4LD became a dinosaur with the 4R and 5R transmissions (gut feeling says no change).

You WILL be replacing the harness and you WILL be replacing the ECM. There is a danger that the 2000 ECM may make some wrong decisions if it can't "see" the correct transmission.

I think they switched to an 8 bolt crank after 94 and before 00, as long as the A$$4LD TC will bolt to the 4R/5R flywheel/flex plate/whatever you want to call the thingy the TC bolts to, you should be ok. You might want to research it first as I'm going off of memory and a few beers.

This question comes up A LOT. (the late-model 4.0 into an early model) I don't think anyone has ever done it, and the general consensus seems to be "don't bother". It is probably possible, I get the impression that the results won't be worth the effort though. I'm not sure.

is it the SOHC?
when did they stop using the OHV 4.0?

This question comes up A LOT. (the late-model 4.0 into an early model)

In retrospect, if I was to consider a swap, it would involve cubic inches.... lots and lots of cubic inches.

My last car was a '93 F150 4X4, 5.8L..... gas mileage with the 4.0 is a wee bit better

The 4.0L OHV was offered in 2000 in the XLS models I beleive. If it were that engine you would be just fine using it.

yes, but...

The OHV engines are the same for the most part, but a couple of things to remember whan using engines later than 97 is the crank has 8 bolts instead of 6, so you need to have the flexplate or flywheel that matches the engine.

The fuel system was changed in 98 so you need to back date the new engine to work with whats in your chassis.

The electronics arent the same either so back date again to your year.

If I was replacinjg a early model with a later model Id just pull the manifold and switch it over to the old one(most of the sensors are on the manifold also) , use the old wiring harnesses, and make sure the flywheel flex plate go with the engine. The exhaust manifolds will bolt up as far as I know, even though the later heads have different ports.

If your thinking of the SOHC, its a better idea to sell your truck and buiy one with the SOHC already installed IMO.

Yes what Steve said is right. Sorry I did not elaborate. If you're going for a later model OHV definitely retrofit it with your existing stuff. Also, this may be advantageous because the late model OHV's make a little more power and are also more reliable.
