You are completely rescuing Ruby from the errors of her previous owner. I love the satisfaction of knowing another system was restored properly. Excellent job. I should probably do this to Grievous now
Awesome job man I never thought about tearing apart the throttle body I might have to do that with my GMC but after I did a full tune up on mine it was great
Brother, this is the PERFECT video for Jeep people. You hit center mass when you said that we're mostly concerned with suspension and tires before this easy basic PMCS. I'm inspired! This weekend, the XK gets new plugs and a throttle body cleaning!
Just did mine " deferred maintenance " the previous owner did not do anything besides oil changes we put new plugs new injectors transmission flush brake flush dif flush power steering flush radiator flush ( then blows a hole the following day go fig) new shocks new tires new water pump thermostat hoses and a new ac condenser. She runs like a champ now at 129,xxx miles shes is good to go. Keep up the great vids and say hi to the fam.
I have been putting off cleaning the TB on my TJ. Much like you with the plugs, I have no excuse that I have not done it yet. I just keep forgetting to pick up a new gasket. Great video, thanks for sharing.
Great reminders, the 4.7 has great pep when they are in good shape. By the way, I see a transfer case on the bench, can’t wait for that video! I’ve got mine in the corner of the garage as well.
Doug,do yourself a favor next time,and put antiseize on your sparkplug threads before you thread them into that aluminum head.They will come out much easier....
I did a tune up on my 4.0 wrangler and i went from 13 maybe 14 to about 16mpg city and about 20mpg highway driving i changed the plugs and since the throttle body was fairly clean i didn't mess with it. edit when i changed my plugs they were just about as bad as yours and i had 99,000 and some change miles on mine.
Champion spark plugs are only good for lawn mower engine's 😂 Autolite is the best plug for Jeeps they last forever and are cheap as well . Now the you've cleaned the throttle body and IAC you should check the EGR valve it could be full of carbon too . Great Job and get some dielectric grease for next time .
Great video as always.. I notice your drive belt is not put on correct the way Daimler-Chrysler have it set up from factory. But hey if is work then you good lol.
Hot damn.. I just went and looked. I seem to have gone alternator, water pump, power steering instead of water pump, alternator power steering. can't believe the belt isnt squeaking. going to have to go a few vids back and see how long it has been like that.
@@colintrout1095 I actually study the 4.7 and 3,7 engine alot. I know alot about them. I was a former Mechanic for Chrysler back in 2004 . My 2007 Dodge Durango had the 4.7 engine when I sold it had 289,000 miles never drop no valve all original. It was well maintenance oil change done every 3000 miles. Main thing about this engine never let it overheat...
The drive belt should had been installed like this from the AC Compressor down to water pump, back up to the Alternator and to the power steering pump and crank and belt tensioner
Totally agree with you! It’s really amazing how much people neglect their cars... even my dad. I’m going to laugh so hard when his engine in his VW Passat seizes😂😵😬. After all your maintenance, I would recommend a cold ram-air intake... even if the kit is from eBay for 50 bucks, it’s still better than stock IMO, especially on a diesel... maybe you could junkyard Cummins swap a Jeep! It’s probably been done, but I’ve never seen one. Instead of cleaning the throttle body, I would’ve just gotten a bigger one(obviously with the pre-mentioned cold ram-air kit). Have you thought about installing bigger coolant tanks on your cars? More coolant will keep everything cooler, since there is more fluid to heat up. Rerouting the pcv valve tube out and set from the engine instead of back into hit will help reduce carbon buildup, too. Just move it back for inspection.
Yoo you mentioned an exhaust leak at the end of the vid. Is it by change a sheered exhaust manifold bolt causing your leak? If you could do a video on that whole repair that would be epic. There aren't many good vids out there right now--yours would be a massive help
I’m having trouble with my 4.0 Wj it’s not staying in first gear at a stoplight or sign it bucks up to 2nd, and takes off in 2nd and won’t downshift back unless I do it manually and go thru all the gears any suggestions
Hey Doug, I know it's semantics, but a tune-up is not possible on a new computer controlled engine, unless you talk about reprogramming the "tune" which in a modern sense, is the fuel/air ratio among other things. A tune-up refers to the tune of the engine, which was much more acoustic back in the old days with manually set dwell times, what RPM the engine idles, at what point the choke comes off, and a lot of other things. This is all set by a control unit, which is what "tuners" mess with when the "tune" the engine. What you are doing is deferred maintenance that should have been done a long time ago. Still good to to, and should be done, just not a "tune-up" Semantics , I know, but an important distinction nonetheless.
Yikes. Lol. Fair enough, but I think we all know it as a "tune-up", right? Also doesn't have the same ring to it. haha. You are definitely correct though!
Haha, yeah I know. Like I said I'm arguing semantics. It's just in the 120 some-odd years of automotive history so many people get so many things wrong because they are referring to one thing but calling it another. Plus you always give good tips and tricks.
Lol I know a oldschool mechanic that will bang them on the lift to shrink the gap. Personally I have watched orielys chuck them around so I am not offended.
What is going on with your Belt. The belt is on wrong look at the Diagram to the right of you. The belt is suppose to go around the Air Conditioner Compressor and go down then come back up. (Follow the Diagram) i can see it to the right in front of the Radiator.
@@DEInTheGarage Yes I did see that you fixed the belt and I think I commented on it. Own a 2000 Jeep Cherokee Sport 4.0 very clean ride never been used to tow or in the woods. It's well taken care of but the one think that concerns me is it's fitted with the 0331 Head that is known to Crack but I have had no problems I know about the Tupy Head replacement if nessary. These 0331 Head castings were fitted on all 2000/2001 4.0 Engines. Hope I can dodge that Bullit. If not I will hunt a Tupy Head down and have it rebuilt before installing. Love my XJ 4.0 I know you have that ZJ with the 4.7 but those engines are not for me I'm 65 and have had my share of wrenching . Last I watched that UA-cam Channel you mentioned ZIP TIES N BIAS PLIES and that guy is off the Hook. I am surprised he gets away with all the swearing on UA-cam. THE MAN IS CRAZY. He got his 100 Thousand Subscription award from UA-cam and opened it with a chain saw. Lol
What's up man so remember you change that letters on that video so I have a 2001 Dodge Durango but the for 7 ho with 206 thousand miles electors broke and I'm getting my head to replaced
Just a recommendation for those of you whose vehicles have an electronic throttle body, like my 03 hemi or 06 lr3, be careful of what you spray on it and do not force the throttle plate to move. If you do it will probably ruin it, that's how I ruined mine on my 03 hemi. Nonetheless good video and I do quite a bit prefer this channel compared to other ones where, people like me who own land rovers because we like them are seen as stupid people. Now, I'm fine with being teased about it but when you go out and attack the people who buy them without knowing who they are or why they did, that's what annoys me.
when you say tranny shifts weird cuz of the tps care to explain 😂 i have an 03 laredo with the 4.0 and the darn thing when it doesn’t have more than a quarter tank it doesn’t like to get out of first gear, if you see this please tag me so i can read your response 🙏🏼🙏🏼
WOW, Can't believe those plug gaps, the worst I've ever seen. Autolite plugs ? What's the recommended plug for your Jeep ? I run NGK in my 4.0 copper plugs, their easy to get to so I use copper. You should also oil the O-ring on the IAC before reinstalling it. GREAT DEMO. ON CLEANING TB. THAT'S HOW IT SHOULD BE DONE, YES SOMETIMES YOU HAVE TO GET DIRTY.
The recommended plugs are Champion coppers. I am giving these a try to see how I like them. so far, I do not and will likely be changing back at the next oil change.Nothing ventured, nothing gained, right>

Those 4.0s love a good TB cleaning!
@@DEInTheGarage yea man! Ive noticed the rpms drop to about 400 when I put Grievous in reverse. I wonder if is this cleaning will fix that.

You’ve motivated me to go look at my XJ’s throttle body!! Thank you!! 😘❤️🐞
Those 4.0L love a good throttle body cleaning!
GREAT! My 2000 WJ 4.0 may be getting ready...
I need to do a tune up on the Cherokee great video
Those 4.0Ls love a good tune-up!
Great reminders, the 4.7 has great pep when they are in good shape. By the way, I see a transfer case on the bench, can’t wait for that video! I’ve got mine in the corner of the garage as well.
Yep, stay tuned. that swap is on its way!
I’m a mechanic but I actually do yard care as my main job I always fix my vehicles unless it’s to complex
Amen to that bud!
Doug,do yourself a favor next time,and put antiseize on your sparkplug threads before you thread them into that aluminum head.They will come out much easier....
That is a good call. Didnt even think of that!
Vaseline works great for anti-sieze on the plugs. Used it for years no issues.

Yea, it is crazy how a little maintenance can awaken an engine

You got some great like to dislike ratio. That’s how you know your a fantastic UA-cam channel. Keep up the good videos
Hey, thanks for that. We really try to make exceptional content
just did a tune up on an 01 grand marquis had factory plugs in it they looked about the same gap as what you pulled out
Gotta love it!
Great video as always.. I notice your drive belt is not put on correct the way Daimler-Chrysler have it set up from factory. But hey if is work then you good lol.
I cannot get anything by you! What is wrong with it?
Hot damn.. I just went and looked. I seem to have gone alternator, water pump, power steering instead of water pump, alternator power steering. can't believe the belt isnt squeaking. going to have to go a few vids back and see how long it has been like that.

Power steering pump super charger ftw
80 horse power AT LEAST
At least, bud.
My god my HO spark plugs were just as bad 🤣 couldn’t believe she wasn’t getting a code.
Right? It appears the 4.7 can take some abuse where ignition is concerned
Lol a "bullet proof 4.7" hahaha nah man THAT is something I've never heard of
There are folks who swear it is stronger than the 4.0.. not sure where they are getting their facts
On the jeep wj facebook pages the 4.0 hate is real
Everyone on there swears by the 4.7 and hates on the “4.slow”
WHAT!! You're seriously not gonna show 7&8? They get it the worst with that stupid uni-fuel rail system.
