4.0

Looking to bypass Ac compressor on 2010 Explorer 4.0 engine. Cannot find a bypass pulley kit so looking at just using shorter belt. Anyone have any idea of the size needed or exact belt number to use?

Hey guys, I am one of those people on the planet who own Explorer. I have 2007 4.0 Explorer with 4wd Limited. I am very far from all of you :(, on another continent. More than 20 hours of flight. :confused: Would be glad to meet everyone.:D

Hello please help. 1998 explorer xlt 4.0 Anyone help. Can anyone help me please. I have a 1998 ford explorer XLT. Crank no start since tuesday..... What I've tried. 1. Checked computer codes shows p1000 p1260 2. PAts system seems to have normal function, put key in light goes out after 3...

Hi all, this is my first post and was wondering if there is a direct bolt on kit for my '93 Explorer 4 door automatic. The last person that worked on the exhaust welded the back pipe to the cat flange instead of using another flange to mate the two together. I'm replacing manifold, y-pipe, and...

I have a 2005 ford explorer xlt 4.0 v6 4x4 automatic with a 5r55s transmission that is blown. I have found a possible donor, a 2002 ford explorer 4.0 v6 4x4 automatic with a 5r55s transmission as well. I am assuming it can be swapped but I am not 100% sure. I have heard that there is a...

Just thought I’d post this info in case anyone needs it too. I recently decided to change the pcv grommet on my 2000 since I’m redoing the entire vacuum system. Below is the part that I ordered through advance auto. I imagine it’s the same for all OHV Explorers, or at the least 98-00...

Is anyone on here running one of these...

I’ve read threads on this site about the tps and it seems that 19.6% is the normal position for the TPS at idle. Mine has recently started dropping to 19.2% at times and I’m getting erratic rpms lately, like a 30-50 rpm change every second. The truck runs really smooth and the rpms stay steady...

I installed a 400ml catch can on my 4.0 OHV, since I was tired of finding oil on my IAC every few thousand miles. Is anyone else running one? I can post a list of parts required including hose lengths if anyone is interested. It’s still too early to tell how much oil it’ll catch, but I’m...

I replaced my coolant sensors almost a year ago and I’m worried I have them backwards. I’m using the dy-1144 sensor to control the gauge on the drivers side one wire connector, and the SW5174 fan switch for the computer sensor on the passenger side two wire connector. Any experts here that can...

Hello all, I have a 2001 explorer sport that after bouncing around for 17 years is starting to get some wear and tear. I have a few issues that I need help figuring out but my BRB is still trucking on well considering. I have some sort of exhaust leak that started giving me issues when...

Alright. I've got a 93 Explorer Sport 4x4. My clutch started slipping. It got pretty bad pretty quickly, despite having the clutch replaced at the end of last year. I have concluded that the rear main seal probably failed and leaked oil onto my clutch. Either that, or the flywheel failed. Either...

Hey I need some assistance with lifting or installing a leveling kit. I want to make my Ex better with offroading and trail riding. Because of how the suspension is set up, a suspension lift is not an option. Or is it? I take it offroad when I can and Ive only neem stuck a few times. Also, as...

Hey all Im new to this site but hopefully you all can help My 04 explorer eddie bauer has been throwing the p2270 code every few days Changed the o2 senspr with one from napa a ngk o believe. Voltage stays around .04 v to .2 volts right now at .02 volts idling it takes forever for voltage to...

Anyone here familiar with “normal” voltages for O2 sensors? Two of my sensors appear to be functioning correctly and are on opposite voltages. I’ve read before that it should be that way. However, the third sensor on bank 2/3 stays steady around .790 volts. Any idea if that’s bad? I appreciate...

I'm looking for an opinion on whether or not it's worth it to have one or all timing chains replaced on my 2007 Explorer 4.0 with 186k miles. Truck is in very good shape for it's age and mileage, and no indicators of tranny problems or anything else major. But I began hearing the typical...

Sup everyone. You can call me Sheepdog just here to learn and teach as much as possible and hopefully build an awesome Explorer at the end of the day with the help of the knowledge base here.:bounce:

Slightly Modified-This thread will be for the 1991 4 door 4x4 that I purchased about a year ago. Not only will I be repairing it, I am going to perform some mild modifications. I had seen it sitting out near the field on one of my neighbors property and ask him if he would sell it. He said that...

Hi all, I just purchased an a 91 explorer. unfortunately it will not shift into its either 4th or OD gear. Yes, there are other threads on this just saying to replace solenoid but I believe this explorer is stuck in 4x4. Does anyone know if being in 4 wheel limits the transmission to 1-3...

I have a 2003 Explorer XLT V6 4.0L with about 142K on it. Recently picked it up used from an owner. Runs pretty well but I do feel like its not accelerating to its full potential. When I go I can hear it shifting gears from 1st to 2nd fine, but 2nd to 3rd seems to take it a second. If I don't...

Hey everyone. So it’s been a long time since I last replaced my tensioner and I really can’t remember what kind the ohv uses. I see Gates “round locator pin” and “v locator tab” on amazon, and both are listed as fitting my truck. I think I replaced it with the v tensioner last time but I’m not...

I've had my 1999 Explorer 4.0 SOHC professionally rebuilt with the stipulation that I would have to install the timing components myself - which I did using the OTC timing kit and a new timing kit with balance shaft tensioner and chain from Evergreen (which is apparently not worth buying) and...

When i am driving and i come to a stop my Explorer shakes super hard, it's idling rough. I don't know why, anybody have any ideas. I like to fix everything myself and i have big plans for this car. If i can get it to run nicely im gonna keep the original engine. I was thinking about swapping the...

My 2001 4.0 explorer has developed a misfire , it's throwing evap codes as well , it's got all new plugs and wires and a new coil pack so I believe the misfire could be caused by the evap purge valve or evap sylnoid , what do you guys think ?

I’ve replaced both timing chain tensioners and have done an oil change with full synthetic high mileage oil. I am planning on replacing belt tensioner and idler pulley. What could this noise be? There are 158k miles and she runs mint. The noise happens at operating temperature and is not very...

Tell me what you think... I know I didn't clean it up lol.

I've already searched around in the threads and can't find anyone who's mentioned doing this. I'm building a 4.0 that came from a 93 Sport to put into my 97 XLT. I've noticed the block casting is different, specifically for the motor mount bolts. Has anyone swapped an early 4.0 into a second...

What it do everyone? I've been looking into options for my 93 Ex and putting a new engine in it. I was looking for something with a little more power than the original 4.0L I currently have in it. I was just curious what kind of swaps people have done with their Exs and what would ideally be...

I've got a 95 XLT 4.0 OHV 4x2, and the O/D light is blinking and it won't shift into overdrive. It didn't start flashing the O/D off light until one day when I was pulling a trailer with only a push lawn mower in it. (nothing heavy) I figured that connecting the trailer to the plug that supplies...

Hello everyone i am a new member. I have an 06 4.0 explorer that i have been having an error code p0401. I replaced the egr, replaced the intake manifold gaskets, and opened a propane tank around the intake and hoses to search for a vacuum leak to no avail. What else could i check to help my...

Alright so all of the sudden my 00 Explorer (4.0 SOHC) has been running like garbage. It started when one of my cats got plugged (it sure shined a nice cherry red). Since then, I have replaced plugs, plug wires, and coil. They didn't help so I replaced the Crank position sensor now too. The...

So while putting timing chains in my 4.0 SOHC I got to the point of every 4.0 when you install a new rear main because it seems like these things go every 100k miles. But when I did I ran into this seal and it looks nothing like the others I've seen. It's got the metal thing around the crank...

Hey, I've recently purchased a 97 Explorer Sport with a manual transmission and 4wd. However, the manual transmission needs to be replaced. What I want to know is if I can go to a junkyard and rip out a manual transmission from a RWD Explorer and use it in my 4x4 Explorer. Thanks in advance!

So ill apologize right off because I'm sure there is a post for this but i have been searching for days trying to find the information i need to finish my project. Base knowledge needed here is that i bought a 90 ranger with blown engine and a broken motor mount and bad radiator for extremely...

As titled, I am looking for the cheapest, and easiest swap for this truck. Its the 4.0 sohc with the rattle of death at 206k miles, original everything. Ill be driving it as is until the timing chain finally goes all the way, it rattles like ****, it sounds like ****, but drives decent. It is...

Howdy, so I've become relatively well versed with the 4.0 SOHC, I ripped one out of my brother's sport trac (2001) and I put it in my sport trac (also 2001). Mine had the very very common timing chain issue where they simply get loose and also my transmission was barely staying into gear on the...

I have a 2003 Explorer XLT that has both rockers rusted out. Anyone got videos or tips and good parts to replace with.

Hi all. I am having some trouble with my explorer with bad fuel millage and decreased performance under load. It currently has 124000 miles on it, but I am unable to figure out the problem. Looking at the real time data I have noticed that the LTFT on both banks are about 20%. Also I checked...

Hello, I recently posted a thread about a nasty vibration with my explorer while accelerating and I noticed something with my 4X4 system and I'm not sure if this is an issue or not. I have a 2001 Explorer XLT (4.0l SOHC) and when I bought it the 4X4 lights would flash about 6 times every...

Hi there guys really just honestly seeing if its worth it to swap the sohc engine into my 2003 explorer with the ohv engine and what would be needed for it. Just looking for some insite i do have some experience with them and if possible il do it in the mear future! Lemme know what you guys...
