P0128 Code - How To Replace Jeep Wrangler Coolant Sensor, Thermostat & Bleeding Coolant System

[@dodgeking9194]

Thanks for showing us where the sensor is it's amazing how they make cars today no consideration for the later repairs that have to come along just design it however and worry about fixing it later

[@JustEmptyEveryPocket]

Agree. It's a bit of a silly design for sure. I'm glad the video helped you.

[@BeeRAD56]

My 2013 Rubicon intermittently throws P0128. I clear it, and it runs ok for a week or so before happening again. It's time to getter done and this video is extremely helpful and greatly appreciated! I also appreciate your quick and concise approach without a bunch of long winded BS. Thank you!

[@JustEmptyEveryPocket]

I'm glad it helped you; if it's happening intermitently you can get an OBD/R2D2/BB8 reader with an accompanying app and monitor the coolant readings. I use the Innova 3210RS OBD2 Bluetooth Code Reader; the cost is around $50 USD ($80 CAD); Just a thought; plus a reader is never ever a bad investment. This should help you determine if the thermostat is functioning as expected. If it's happeningg intermitently, my guess would be that the sensor has gone bad. As far as getting to the point; it's the editor side of me; I like quick cuts and I try to keep the how-to vids as short as possible. Thanks for the feedback it's much appreciated.

This is a great video in all aspects. Thank you

[@tdz69]

Thanks for this video. I have a 2014 JK and cannot find the torque spec on the temp sensor. Would you happen to know? I’m just gonna tighten down snug and check for a leak and call it a day if I can’t find the toque spec.

[@JustEmptyEveryPocket]

I just hand tightened it; no leaks.

Informative and hilarious, Edutainment at its finest. Thanks!

Glad you liked it; thanks for the feedback!

You don’t need an OBD2 to read check engine codes on the Jeep. You just turn your ignition from OFF to ON 3 times rapidly, ending in ON position and the code will briefly flash in the ODOMETER readout.

[@JustEmptyEveryPocket]

I had heard this; tried it on mine and couldn't get it to work; I was doing something wrong. Gave up and bought a reader. But thanks for the info; If I ever have another failure that throws a code I will include this advice in the vidceo.

[@Florida_Man_Robb]

@@JustEmptyEveryPocket Make sure you start in OFF position, and you have to turn 2 clicks to the ON position (not 1 click to the ACC position), all 3 cycles have to be really fast as well, but it does work.

[@tdz69]

Better write the codes down also. If you don’t and forget what they were, repeating this process with the key won’t pull them up again.

[@IDAHOverland]

Thanks for a great video on this. I'll be doing this in the morning. Also - just needed to comment on how beautifully clean you Jeep is = it looks new. I take mine off-roading/overlanding every month with my 7 y/o daughter - and mine looks like it's 11 years old.

[@JustEmptyEveryPocket]

I am so glad this video helped. Last fall I put POR15 on my under carriage and it really helped keeping it clean and to keep it looking new. I don’t get out quite as much as you do; but I managed a couple off-road trips this summer; so don’t think my Jeep doesn’t get wheeled heheh. Be sure to checkout “The Adventures” section on my channel :) Again, thanks for the feedback and super stoked that my video helped you.

[@247sikvideo]

Great video awesome production and very informative. Thank you. I have some shopping to do. 😎😎 oh and the INTRO was 🔥!!! LOVIT!!!

[@JustEmptyEveryPocket]

Thanks for the comments; glad you found the information useful :) hehe yeah I’m a huge Marvel nerd what can I say?!

[@jonrob4675]

2016 wrangler with p0128 Thanks for making it look easy I’m still hesitant about diy 😅

[@JustEmptyEveryPocket]

This repair is really easy; the hardest part is the burping; it just takes time and a spot that can get a bit messy hehe. For me DIY isn’t an option; shop rates are just too expensive these days; I can’t imagine how many thousands I’ve saved already.

[@HumbleHotshot]

Dude! Great video!! Informative, good intro, shot in high quality, and some humor thrown in to boot! I could do without the profanity, but that's just me. Good channel name as well, I'm honestly shocked that you don't have more subscribers. As a mechanic, I'm never a fan of the "parts canon" approach of replacing everything. Some simple tests can reveal if its the thermostat or the temp sensor that is causing the code. Also those hoses didn't look like they needed to be replaced. But hey, it's your own vehicle and wallet so that's a different story than working on someone else's rig and within their budget. Thanks for the quality content. God bless!

[@JustEmptyEveryPocket]

Thanks for your feedback. I’ll try to cuss less hehehe. My wife gives me crap for that too. I agree with the “parts cannon” comment as well; what I am going for is trail reliability. I figured I was there so I swapped hoses out and did both sensor and thermostat. I usually don’t do this and I will try to make a note of this in future content. As far as subs; I do zero marketing for this channel. I’m actually a bored Documentary film maker looking for something to film. I used to film a series called “come drive with us” which focused on the world of professional R/C car racing where 30 or so people around the world get paid to race toy cars for bowling trophies. COVID basically ended that series so now I am focusing on something else to film…and also a few tax write offs heheh. I hope the channel takes off but if it doesn’t it’s not a big deal to me.

[@HumbleHotshot]

@@JustEmptyEveryPocket thanks for the reply! All just friendly feedback here. It's neat to learn about your background and it certainly explains the quality of filming/ editing in your videos. I started a channel roughly two years ago and it has slowly grown to just over 2k subs.. still very small relatively speaking! My intention was to create some trucking and mechanical content while also sharing God's Word. It's been a lot of fun and by God's Grace it seems to have actually reached some people for their good :) I have absolutely no editing skills and really need to step up my game in that area.. I could learn a lot from your videos! God bless.

[@Tunaslayer1]

I have a 2022 JLUR....It must not have an Asshole sensor.......Because I drive it every day!!! And no code!!! HAHA! You just got a new sub, and a Love!! Very entertaining, while educational!!!! Great Job!!!

[@JustEmptyEveryPocket]

Glad to hear you don’t have codes yet :) if you want a good laugh checkout my latest axle seal/hub and axle shaft install video. The part where TeraFlex screws me over is pretty funny (especially if you’ve watched ‘How I met your Mother’).

[@LosDelRanchoFilms]

Thank you for sharing man! Great video

[@JustEmptyEveryPocket]

No problem; happy to see it helping people out.

[@triptonmiller8532]

The seam that runs along the stock intake air hose, mine has a split in it at the left end. Would that be contributing to the issue. As you can assume, I am not mechanically inclined. I did see a video where the dude got it ftom the top without having to remove the wheel, etc.

[@JustEmptyEveryPocket]

First off, I ONLY removed the wheel for this videol it made filming it a bit easier and showed exactly where the sensor was a bit better. That's not a step that you have to do. Second, are you telling me your air intake has a crack in it...after the filter? If so, that's VERY bad news...the engine can suck in dust...

[@nayabj0820]

Thank you for your video. 2017 jk wrangler My car po128 code, so I replaced the thermostat and coolant sensor, but the check engine light still comes on.

[@JustEmptyEveryPocket]

It can take up to an hour for the code to clear on its own. Do you have a code reader that has the ability to clear codes? The only other thing P0128 could be is the coolant level. Is it low?

[@nayabj0820]

Thank you for your answer. I disconnected and reconnected the battery to clear the error code, but after driving for about 30 minutes, the engine warning light came on again. There is enough coolant and the temperature gauge is normal.

[@ewowen]

Great video thanks. I went from a PO128 to a PO118 when I replaced the sensor. Turned out I didn't get it plugged back in securely.

[@JustEmptyEveryPocket]

I’m glad the video helped; I will put a note in the description about the P0118 code.

[@AtomLiLiu]

The Temp sensor you used looks like 5149077AB for the engine oil temp on oil filter adapter but not the 68164627AA which is Coolant Temp to Cylinder Head.

[@JustEmptyEveryPocket]

It’s the NAPA UNITS5805 which is a coolant temperature sensor not an oil sensor.

[@DrumHog65]

You ain't kidding brother! That connector is a #$%&^! to get off. Hardest part of the job.

[@JustEmptyEveryPocket]

Oh good; I thought it was just me lol!

[@thopkins1290]

I've tried twice to get mine out. Luckily, my 2010 has the sensor near the top where i can reach it. But, that tiny piece of hard plastic that's locking it in place won't budge. @@JustEmptyEveryPocket

[@thopkins1290]

I love your intro!!! If only I could remove the @#$# plug. I'll try again today...using some trickery with a small allen key and tiny pliers.

[@thopkins1290]

It won’t come out!! I pulled the red piece off but I think the red piece is part of the kicking mechanism (little pieces of plastic. I’m off to Reddit for help in this one

[@emilyrae9923]

Had this code pop up on my 2015 wrangler, I checked the coolant and the over flow jug was low and the cap was off. Possibly from the dealership not putting it back on for maintenance? Would this trip that code or is it as what’s stated in the video. Thanks :)

[@JustEmptyEveryPocket]

Mine was from a faulty sensor; my understanding is that a P0128 is only from sensor or thermostat failures. I hadn’t heard of a loose cap; but anything is possible :)

[@bulldograzor]

Yeah, I had a bad radiator plug and I just replaced it also from the dealership. Also remember, cold temperatures makes it go off if you have bad coolant so in a way, mother nature lets you know if the fluid is no good.

[@danmulkiewicz5515]

Is the mess on the garage floor from the funnel boiling over? DAMHIK

Yep hahahah!

[@JustEmptyEveryPocket]

What is the temperature gauge showing? If it’s on the warm side, which it sounds like, there is likely a bubble in the coolant. Park your Jeep nose high overnight (with the Rad cap off) or burp it for 20 minutes or so with the engine running.

[@c1b14]

[@queensapphire7717]

What about just removing some plastic plugs to move the cover under the fender.

[@JustEmptyEveryPocket]

I’m sure it was possible, and may have helped, but I wanted to demonstrate that it can be done by leaving the inner fender in its place.

[@Rizzard_of_ozzzz]

I did this and still have a check engine light.

[@JustEmptyEveryPocket]

Is it throwing a new code? Does your electric fan come on? Or is it on constantly? P0128 can also include a faulty fan.

[@queensapphire7717]

109 inch pounds for Thermo torque.

[@JustEmptyEveryPocket]

That’s more torque than anything else being screwed into the aluminum block. Where is this spec from? I did mine to 26 max and no leaking at all.

My wife's 2013 Wrangler has been the biggest pile of shit we've ever owned and the worst vehicle I've ever worked on. It's almost as if they purposely made simple components a pain in the pass to reach or you have to take the entire top of the end apart to get to. I hate this vehicle. She loves it because she doesn't have to repair it every month.

[@JustEmptyEveryPocket]

hehehe I'm sorry to hear that's been your experience. Mine went 9 years without any issues at all. The first problem I had was with the oil cooler/filter assembly. It was 6 bazillion below zero here that Christmas and it cracked. Big mess; easy fix but yes, had to take entire top-end of motor off. While I was there, changed the spark plugs/coil thingies too. The suspension is super easy to work on, but I agree with you, some parts of the power-train are just flat-out stupid to wrench on. Clearly designed by an engineer that has never ever worked on a vehicle in their entire life!

[@triptonmiller8532]

I have 2013, and this is the first time I ever got an error code. The P0128. My mechanic is very good but also very expensive. He will rake me over the coals . I'm going to look for somebody who does this on the side.

[@eriknash8783]

@@triptonmiller8532 I've seen that code for years on my wife's Jeep, especially in the cold months. I just reset it now. Not warming up in allocated time is not really a concern to me. On my wife's 2013, we've been through two transmissions, 4 axle seals, rear brakes keeping getting replaced due to axle seals. Radiator, heater core, Alternator, garbage plastic oil cooler in the intake valley which will probably fail again, multiple failed engine sensors, front suspension components, valve cover gaskets, ignition coil x 2, and leaking fuel injectors, etc.... The only shockingly positive and strange thing I can say is that it has over 150,000 miles on the original front brake pads. They just seem to never wear??? And braking performance is great, as well. Interior has held up very well, though.
