1998 Jeep Wrangler 2.5L 4 Cylinder Engine Removal Guide

A guide for engine removal on a 2.5l 4 cylinder Jeep Wrangler

[@cocainechestpains]

This is awesome, really big help for me. Im pulling my 2.5L tomorrow, trying to get as much info in as i can. Seems fairly straight forward. I was gonna take off the fenders just for more room but i dont think i will after seeing this.

[@ryaneandersen]

THank you so much for this guide. Im getting ready to pull my 4cyl to drop in a 350. This is very helpful.

[@jasonwadsworth9609]

Ryan Andersen I'm gonna put a 5.7 vortec in place of my 2.5 also. Do you have any helpful hints?

[@gurutrips9440]

I know it’s been 2 years but..How did your swap go ? Any good tips for the 350?

[@sladelewis2421]

Never knew Billy Bob Thornton(a few times you sounded just like him) knew how to pull an engine. Well done!

[@SolidGroundStaging]

We have actually worked with him with our audio company. He is a nice guy.

[@tk429]

Great video, I'm fixxing to swap the motor in my 98 Wrangler.

[@user-cu4zl9jn4n]

[@klb1956]

Good job! Nice looking Jeep!

[@MrJoey1570]

Great video!

[@SolidGroundStaging]

Thank you!

[@firemanmike1619]

great information. I plan to do this soon!

[@timcallinan]

Thank you for your video. I had the same problem. Piston disintegrated in cylinder #4. Im rebuilding the engine now. I think its going to cost me $2000 to have it completely rebuilt.

[@SolidGroundStaging]

Tim Callinan it seams to be a very common problem.

[@aburch5]

Same thing here 99 Wrangler 2.5L 121,000 Miles Cylinder number 2 Disintegrated and completely destroyed the block. Managed to find a $1697 crate motor. Engine is mostly put together on a stand as of an hour ago.Waiting for a new clutch and some other odds and ends to show up in the mail today. Then Hopefully Dropping it tomorrow night.

[@LuvOfInstruments]

Cylinder #4 did the same for me. Currently just sitting under the garage until I find a motor

[@jalengantt3655]

thanks for the tips!

[@SolidGroundStaging]

Thank you for watching!

[@jacobscaggs]

helped me a lot! Thank you!

[@mazamike]

$2100 for a crate engine and $350 for the core when I returned it...to me it was worth it rather than rebuilding plus the engine came with a three year warranty

[@krwiles]

Maza Mike Jasper motor?

[@tariqalbalooshi8946]

Hla Are my friends in pocket change Wrangler engine from 3.8 to 3.6 Please Alavade way

[@MKVA2]

What is the line that connects to the fuel regulator valve?

[@shanesmaineshop]

Mine sounds just like that but when I rev it up the knock goes away. any idea as to what it could be? thanks

[@JOSESOTO-gy1xr]

Noise un the driver side what can be?

[@shanesmaineshop]

I don't know still trying to figure mine out. I think I have timing chain slap.

[@LuvOfInstruments]

We're you able to get the top bolts from the engine bay?

[@GeorgeHamberhill]

Great video, Thanks for sharing, do you have video on the engine rebuild? I have subscribed to your channel!

[@SolidGroundStaging]

GeorgeHamberhill sadly I didn’t do a video on the rebuild I wish that I had.

[@nicfleck3213]

Not sure if you can help me out or not but we are rebuilding my moms jeep motor but when i got to the fuel rail to relieve fuel pressure, there is no test port how should i go about relieving fuel pressure?

[@MatHelm]

At 1:42 "Make the engine weigh a whole lot less"? Not hardly, and of course not the reason you drain it. Now draining the oil is a new one. I mean I guess in your case (assuming you're going to rebuild), why not. But if there are no plans, you always leave the oil in a block just because the oil is worthless, and the next guy might want to test it without wasting 5 new quarts of oil. Also, the ECU pulls a vacuum on the gas tank for emissions check, but there is no pressure. So cap stays on because everything's always safer that way. And it has zero effect on fuel pressure. Tank vents have one way check valves on them, so they release any pressure, but close with the aforementioned vacuum is pulled.

[@andymiller3771]

How long did it take to get it out and get the new one in.

[@user-jc1gm7hn5x]

مكان الزيت مكان المقاس على

[@justinill2705]

Do you have to support the transmission once you remove the engine? Or is the crossmember strong enough to just leave it hanging there

[@vanillagorilla753]

Damn where Tf do you buy a half millimetre wrench 🤔

[@SolidGroundStaging]

😂 did I say that?

[@haroldmilroy4489]

1/2 mm wrench????

[@DaddyDean87]

what was making the knocking noise? my 2.4 is making the same noise.

[@J-W.-]

A connecting rod bearing or piston I'm pretty sure.

[@pedromolina1214]

espero respuesta okey

[@notreallytyler9910]

I know it’s been awhile since you posted this, but about how long did it take for you to take this engine out completely?

[@SolidGroundStaging]

I’m trying to remeber. My guess would be if it was without stopping 6 hours solo.

[@socalRooster]

What did the build run you $$ ?

[@nickmoreno3885]

what kind of transmission do you have on that jeep? good video, thanks!

[@SolidGroundStaging]

Nick Moreno it is a 5 speed manual.

[@thecamaroarmy1004]

Have a Jeep identical to that a year older

[@mcsstudios101]

doing the same job..how was it getting back in?

[@SolidGroundStaging]

mcsstudios101 by myself wasn’t the easiest :) if you have a friend it will be much easier

[@camdennorwine7304]

How big are your tires? And do you have any kind of lift?

[@7Monza6]

What is a 1/2mm open wrench?

[@SolidGroundStaging]

It is of a very rare breed. Found only in Nova Scotia, one time per year.

[@jimepler9347]

Hey, great video. How did your rebuild on that engine go? Did you do most of the work yourself? I'd like to rebuild my 1995 2.5L 4 cylinder Wrangler engine and was wondering if it's worth it.

[@aaronnovak1490]

Hi Jim, I just overhauled my '93 2.5L which is the same setup almost exactly. Took me me about 2 weeks with a out of pocket cost of about $675. I replaced the cam and lifters, had the cylinders punched .020 over, replaced the exhaust valves, reground the intakes, re-cut the valve seats, new timing set, bearings, media blasted the block, epoxy primer and enamel topcoat. Runs like a sewing machine now....this is one of the easiest engines to overhaul and very cost effective.

[@jimepler]

Aaron Novak Wow, that is a great price. I'm not sure how much block work I'm going to need. Two different mechanics just told me to swap it out with a used engine, that a rebuild isn't worth it. I need to check with some local machine shops. I figured I'm going to need to spend at least $1500 just for the machining and parts without assembly. I'd like to try and assemble it myself but I've never done it. Id need to teach myself with KZbin videos and the FSM.

[@jimepler]

Hey Aaron, Do you recommend an online parts distributor to purchase the timing set, bearings, gaskets, cam and lifters? Also wondering if you purchased new pistons and rods? I'm also thinking of putting on a new clutch assembly since the manual recommends changing it when the engine is removed. Prices vary on parts and I want to make sure the place I end up using is reputable. Prices on Partsology.com are very reasonable but I'm not sure if they're legit.

[@aaronnovak1490]

northern auto parts is good for the engine internals. most machine shops charge $150 to bore and hone the block. I used the original rods, new bearings and pistols. most mechanics don't overhaul engines so their opinions are pretty limited.

[@jimepler]

thanks, Northern Auto Parts looks like a good bet. I've been surprised at how many people have told me that I shouldn't rebuild. Lots of people on forums told me the same thing. Rebuilding seems to make the most sense, both from an economic standpoint and a practical standpoint. Why pay $600-$1200 for a used engine with as many (or more) miles than on my engine which could crap out on me at anytime? Seems like a lost art. I'm pretty sure 20-30 years ago EVERYONE would have recommended an engine rebuild. I was even told that I wouldn't be able to find a machine shop that will do blocks anymore, that everyone will only do heads. I haven't started looking at local machine shops yet but I can't believe that is true.

[@martinez884990]

Nice video. I'm going to be pulling my motor out soon, do I just wrap the chain around the motor?

[@SolidGroundStaging]

Alex TL Martinez 8:17 shows where I connected. Not sure if it is the best but it worked.

[@martinez884990]

Solid Ground Staging I got it out! Came across a speed bump. I'm replacing the 1998 2.5 L engine with a 1999 2.5L engine they look identical. But the clutch spline's are different. Will the 1999 engine work with the transmission from the 1998 2.5 L? Both the flywheels are exactly the same. Also thank you for replying. Not sure if it matters or helps but the vehicle I'm working on is a 1998 Dodge Dakota Sport.

[@SolidGroundStaging]

Alex TL Martinez that is a great question. I’m not exactly sure. I would call a dodge dealership or a local junk yard to see if they would know. I’m glad you got it out and hope everything works out great for you.

[@lukek3953]

What is the gas mpg on 1998 Jeep TJ 2.5: 4 Cylinder?

[@JonathanStMarie]

Canadian Cherokee I regularly get 20 to 22 mpg on my 1998 Jeep TJ, 2.5L, 5 speed manual. Tires are stock and gearing is stock at 4.10. 240k miles.

[@SolidGroundStaging]

Usually I get 12 to 16 but I do have oversize tires.

[@MattJoinesVietnamWarAirsofter]

+Luke K VEry bad on a yj. i get 9mpg

[@chriscarlson4789]

the transition sucks to disconnect

[@556poor7]

How many miles on it?

[@SolidGroundStaging]

556poor it was at 180,000

[@kurtwolford5801]

half millimeter lol

[@SolidGroundStaging]

Very rare. Very rare. 😂

[@jackscruggs1536]

2.5 way under powered.

[@SolidGroundStaging]

It is pretty weak but fun to roll around.

[@cfvrq]

Don’t forget all WW2 military Jeeps were 4 cylinders.
