Am I able to use a 98 4.0l sohc vin e from an explorer in my 01 ford ranger that also have a 4.0l sohc vin e. The reason im wanting to know is because I will be getting a pretty good deal on that motor and ive heard all I have to do is swap the intakes but I want to clarify that I am able to use this motor before I make the purchase thanks in advance

 

Yes, it will work fine.
It will need new timing chains, cassettes and tensioners, '97 to about '03/'04 4.0l SOHC engines had the older design which failed often, newer design works much better.

Also on the 4.0l SOHC it is a good idea to replace the Knock Sensor, they are hard to get at, and do need replacing.
Check the thermostat housing carefully, they are prone to cracking and leaking.

And replace rear main seal, but that's for anytime any engine is out.

There were 4.0l SOHCs made with an internal balancer shaft, these were used in 4WD vehicles with "Live" front axles, always engaged.
People have swapped these both ways with no problems with vibrations, so no worries on that part.

 

Can confirm, 03 sohc motors are good years. Live axle swaps are also fine. No need to swap intakes from the engines. I wouldn't use that year motor though.

 

If the 98 engine is in good condition and has the updated cassettes with good chains and tensioners, it should be a good engine to install. It is basically the same engine as the 01 Ranger. As noted, the intake is different. Some people like to use the Explorer intake because it provides a little more hp but the Ranger intake is supposed to be better suited for a truck. I don't know if the 98 Explorer provides better hp.

 

Yeah what im planning on doing is pulling the motor I have and completly repairing the motor and adding a few goodies and use the explorer motor that has 98k on it for 450$ With a 6 month warrenty and with the explorer intake why isnt it best suited for a truck? But thank you guys for the reply I really appreciate it!

 

I believe the explorer had more 02 sensors. 4 compared to 3 on the ranger, you might have issues with that. As well as the 4wd system unless you had a manual t-case. They changed the wiring/modules around sometime during 01ish.

 

1995 and up Dual exhaust has 4 O2 sensors, single exhaust 3 O2 sensors

The downstream O2 sensor(s) is to test if Cat converter is working, on dual exhausts there is an extra Cat converter
