man i swear ive been looking everywhere for days trying to find info about those vacuum lines for the EGR and purge. got a code reading for AIT sensor and i discovered that the sensor was removed by the previous owner. said he had a poor idle and just stuck a bolt where the sensor was to plug it. then EGR started flashing on the scanner but when i was checking it out i broke the vac lines :( im not even sure if those valves arent doing anything. it ran exactly the same but i temporarily stuck a random hose from my bleeder kit over the broken lines until i can find out how to replace them. thank you so much for this lol
man, thank you for this carefully made video! I'm trying to hunt down an internal coolant leak which I suspect is from my lower intake manifold gasket, so this video is a life saver for what size sockets to use and what wires to get out the way.
Wow! What a fantastic video, well done! My son's '98 Explorer 2D Sport has the P0174 lean condition code, but it runs great. I'm hoping I find an obvious vacuum leak up top, because after watching this video, I DON'T want to hassle with the job you covered in this in-depth video. Yikes! Thanks for all your great work. I'm a new subscriber!
@@toddouchida3451 thank you. Yes there are many other possible vacuum leaks that may occur other than this. I fixed all other leaks first and still had a problem. It was a lot of work but well worth it.
Thanks for showing the process in its entirety. I have a question regarding the OEM lower intake manifold gasket. I can't seem to find a kit online that sells it in one solid piece. Do you know if all of the aftermarket gaskets are in two pieces? Also, could you tell me what some of the symptoms were that led you to replace them in the first place? My Explorer recently started stalling at idle and seems a little low on power. thanks in advance, your channel has really been a blessing.
Thank you! I am happy the channel is helping you. First, the two piece lower manifold gasket is an updated gasket and is better than the single. Since it is a two piece it is supposed to seal better and be more resistant to coolant leaks. I replaced mine with a two piece and it is working great. Mine was running rough at idle and it got worse when the weather turned cold. Some mornings if it was below freezing it would barely run and would always stall at idle. Sometimes I would have to give it gas at a stop light to keep it running. I fixed every other possible vacuum leak and it got better, but was still running lean. If you think yours is stalling and not having any other issues, you might want to try the upper intake manifold seals first. That is a lot less work and may fix your problem. Thank you for watching and if you have any other questions please do not hesitate to ask.
Egr should be disconnected anyway, vehicle will run much better. The o2 sensor will sense the lean condition, and compensate for it by enriching the mixture. So it'll run a long time with an intake air leak
@@TheStanleyWay our 2000 Ranger got so bad, it dumped gallons of coolant into lifter valley area, at 165k miles. But still made it to garage, barely. The aluminum intake lifts off the cast iron block from expansion under heat. Those lower intake bolts need to be loctited, and sealer around the water jacket holes both sides of gasket, to last
I needed this I have a 97 ranger 4x4 extended cab with the 4.0 and It has water coming out of the upper intake I'm not a mechanic and my ranger has been down for 2 years looking for a video to help me finger the water spraying out after running for a little bit wish I was good at fixing stuff but I was with my old 79 f150 but not so good with the newer ones to much junk in the way and lack of having the right tools

10/10 video brother awesome job I wish I can have videos like this for all my projects
Thank you!

thanks for the in-depth video and not too much none sense talking. this was very informative and helped so much! I'm doing my gaskets changes now.!

My leak was so bad the computer could no longer enrich the mixture enough to run correctly.

You can do it. Take it one step at a time and don’t get in a hurry.
@@TheStanleyWay I definitely will be taking my time and watching your video every step so I don't miss anything
I have to do the same thing on my ranger, and sure not looking forward to it thanks for the video.
@@ride4kix I wasn’t either. Take your time and you will not regret it. She runs so good now.
Would this be similar to a 1991 ford explorer?
I have never worked on a 1991 but it is a 4.0 and the intake manifold gaskets look very similar. So yes I believe it is similar.
Is this a ohv motor or sohc motor?
OHV
