I need to show this to the mechanic I’ve been taking my Jeep to. Took it 3 times already. And he doesn’t fix it. 😢😢😢. Wish I had the ability to fix it myself. You make it look so easy.. Thank you for sharing.
Turning your heat on high only increases the fan speed for the HVAC system. The coolant flows the same to the heater core if your heat is on high or even off. Just an FYI.
🤣 that sound effect after you said to spit on it. Lol subbed. I don't even own a jeep, nor do I have any issues with any of my vehicles. Lol I just love jeeps, been saving for one for awhile now. Hopefully this late winter I'll get one.
Watched a few of these videos and it would make sense that the temp sensor fixes all of this if you have well under 100K miles since that’s when you need to replace coolant. The varying temps to me would indicate a malfunctioning sensor.
I have changed my thermostat, water pump, Coolant temperature sensor and radiator on my Jeep Wrangler Rubicon 2015. When I get up to 60 miles and up my temperature fluctuates and goes up how can I fix this problem?
For those of us with factory fender liners, how do you remove it with the pop rivits at the end of the fender flares? Another channel stated that those fender rivets have to be replaced by new ones and need to be installed with a rivet gun!
@@ronfrieborn2276 mine does the same new water pump ,radiator ,radios cap ,thermostat,should I change sensor ?I aslo purged it got bubbles out ,only good for about a week then does back to do the same goes to hot then goes back down after 30 seconds and then after that it’s fine ?any solution ?
I’m having trouble with my temperature going up and then yes coming down. I tried flushing my system but i can’t seem to get all the fluid to drain. I spent all day yesterday trying to figure it out. I wound up putting an all new water pump in, which thinking now it most likely wasn’t necessary. My fan runs hard and makes a lot of sound. I thought i drained the radiator, added water and a special flush solution, and it apparently still had coolant in it, and now I’m freaked out.
Up and down temps means your coolant level is low. The air in the system heats up and when the coolant makes it through, it cools back down. You have to burp the system to get the air out. There are many ways - but the easiest and cheapest is to park your vehicle with the nose uphill. You want the radiator cap higher than the rest of the system. When cool - top off the coolant. Run it some more and get it warm again. Let it cool with the nose up again. Top off the coolant. The air will typically always go to the highest point - so use that to help get all the air out.
@@oscarwinner2034 thanks bro! My reservoir tank appeared full so I didn’t think that was it, after reading your comment my radiator took almost 3/4 of a gallon of fluid. Thanks
Mine had a check engine light for bad thermostat. The guy that replaced it just took it off and put new in and maybe added little bit of coolant few weeks later temp started going up to 250 then fan cools it down. Any idea what I should try first???? Thanks
Question : my 2016 jk is doing the same thing has been to the dealer 10 times in the pass 9 months. They changed the thermostat 3 times , radiator , water pump and cleared any water pockets 3 times. Still the same issue !!! Coolant is always leaking from somewhere 1/5/22 will my 11th time at the dealer. Could you think of anything else it could be or this is 100% the fix ??
Check that coolant purge screw on top of the thermostat (under the intake) first off and make sure it has an O ring on it. If you can’t get to it easy, you can always look at it while it’s running to see if it’s leaking there. It seems to be the culprit for most pentastar engine problems cause it’s cheap, plastic, and sometimes the O ring is missing or broke. If it’s not that the coolant temperature sensor is worth a shot cause that one is super cheap. Best of luck man!
I had a hard time finding my coolent leak since it was coming out of the back side of my engine. I ended up replacing my oil filter/cooler housing and got the leaking to go away. There are some good videos on that replacement online if you are willing to save some money.
Oil cooler under the intake. Plastic ones were defective. They have remanufactured them now to be better. If you’re leaking from the transmission bell housing to the bottom middle of the undercarriage…that should be your culprit.
@@mikemike7397 7:19 I had the same problem if you look down below your oil filter on top of the motor if it looks like oil under there definitely is a problem I replaced my oil cooler or oil filter housing with upgraded aluminum housing to find out that that wasn’t my overheating problem, I still had the same problem I put in three different aftermarket thermostats which are also cheap and not good. I took the one thermostat and readjusted the spring and it actually worked better. And maintain a steady temperature and I was good for the night but the next morning he started doing the same thing again I’ve flushed the radiator and bled the system for 15 minutes through the bleeder screw It looks like thermostat is opening and closing according to the temperature gauges but it fluctuates back-and-forth in between different temperatures going to buy a temperature sensor and a new Mopar thermostat. The top radiator. Hose is really hot bottom hose is cold and radiator is also cold to touch. Radiator is building pressure if I release the pressure out of my cap just a slight, turn then the temp gauge goes back down after running for a couple hours I was told a head gasket, which I’m not ruling out my instincts tell me something else!!!
My Jeep is doing that but my heater does work I already changed the pump ,coolant sensor, and thermostat and it still says it's overheating but it's not what could it be
I have a 2015 jk and it does the same thing except the reservoir feels full of fluid but doesn't go back to the radiator has a new thermostat and doesn't leak anywhere will replacing the sensor fix this.
I like your video and will try this, but I'm now interested in the very last part you touched on about the TPMS light and running 35s. Just bought a 2015 Wrangler and it has 35s and the light will not go away. Can you comment more on this and why the light wont go off?
Get JScan and you can change the tire sensor perimeters or even completely turn off the TPMS. You can also re do your tire size while you are at it so your speedometer is correct and your shift points are where they are supposed to be
Hey man loved the video, i had a cracked radiator had to replace it. Had a guy come out out it in i also installed the new thermostat myself very easy. But he didnt do any of this. Well while i was driving to work thecneedle raised up just over the middle. Can I and should i do this He was a great mechanic but i dont think he filled the radiator enough? What do you think or any jeep wrangler owners appreciate you guys. Got a 2012 jeep wrangler. Should i go ahead and chnage the temperature sensor also?
I think the temp sensor should be fine unless it starts randomly going up and down while the car is warmed up and been running… big thing to check is purging the new coolant your system got. It’s a super common problem, that air gets stuck in there and causes the system to go haywire. It’s super easy and free. If you have the 3.6L I purged mine in this video… you’ll hear it hissing out of there - if it had an air pocket. Best of luck, take care!
@BrianEaly thanks Brian I'll have to do that I just follow like you did take the cap off the thermostat and leave it off and fill it up? I'll watch it again I really appreciate the reply. Helps alot
OK my jeeps temperature senor is moving to the 3/4 and back just back and forth my fans start at full speed my heater works fine tho what is causing my temperature senor to do that
Odds are it’s one of the three + 1. First check the coolant level. (That’s free and the +1) Then try purging the coolant system… that’s in the video of how to do, that’s free, and super common in the 3.6 motor. (Usually the problem). Air in the system screws up the sensor and makes it go all over the place. If not those it’s either the thermostat, or the coolant temp sensor, sounds like the coolant temp sensor if the heat is still blowing. Hope you get her fixed. Best of luck.
I think I blew my oil cooler or coolant hose that connects to it because I didn’t burp/bleed my system after I lost coolant due to a heater core leak. What do you think? Definitely going to subscribe! Best advice ever. If you can please respond to my question when and if you get this.
I did everything you did, except I didn't change the thermostat. Got back in the car and the gauge on the dash jumped up to 190 . It's not running Hot, but my electric fan is spinning really fast, then it slows down. The gauge on the dash still shows it is running Hot. Any comments would help me out.
My fan seems to run hard a lot, and temp goes up under a strain on interstate. Could this be my issue also? Radiator and thermostat have been replaced. Only happens on warm days. Drove to Virginia from Georgia during winter with no issues.
Thank you. The shop told me something different and tried to charge me 600. I said hell naw straight to TH-cam! Love my Jeep owners! Thank you
Make sure you buy a 10mm beforehand cause everyone know the 10mm is always missing
😂True
My brother works in Hvac and he calls it "the illusive one."
I need to show this to the mechanic I’ve been taking my Jeep to. Took it 3 times already. And he doesn’t fix it. 😢😢😢.
Wish I had the ability to fix it myself. You make it look so easy..
Thank you for sharing.
You know, I like teaching my kids by showing them youtube videos and then working on cars with them
We won't be using your videos anymore
Turning your heat on high only increases the fan speed for the HVAC system. The coolant flows the same to the heater core if your heat is on high or even off. Just an FYI.
By turning it up full blast you remove the heat quicker from the engine bay which in turn allows your HVAC to work at it's maximum.
Great video. Very helpful and fixed my jeep. Saved me a mechanic bill!

So after Ive done this, and my Jeep is still running hot would it be safe to say that perhaps I need a new radiator or water pump?
I have changed my thermostat, water pump, Coolant temperature sensor and radiator on my Jeep Wrangler Rubicon 2015. When I get up to 60 miles and up my temperature fluctuates and goes up how can I fix this problem?
Hello dear, have u fixed it? if yes, can u please share you solution
Sir, thank you so. Problem resolved. Jeep running like a champ.
For those of us with factory fender liners, how do you remove it with the pop rivits at the end of the fender flares? Another channel stated that those fender rivets have to be replaced by new ones and need to be installed with a rivet gun!
My temperature shoots up like yours I change the thermostat, I didn’t change the sensor. It still does it. Fans work. Should I change the sensor..
I did the same and its doing this. Maybe the sensor needs changes too
@@g-trooperg5876 u fix it.. i changed both an mine still going up an down
My jeep is doing the same thing. Coolant goes into the overflow bottle but doesn’t suck back out Into the radiator.

My 2010 Hyundai has a fluctuating temp too, goes from almost on H to half way where it's supposed to be in the matter of a couple minutes
Same here, it started doing that right after I changer the fan censor
I have 2016 Jeep Wrangler Unlimited Rubicon and it goes up 3/4 temperature is normal.
My temp goes from 208 to 228-230 max and then fan comes on and goes back down. Running on interstate runs at 222 or so. Is this normal?
Where is the best place to get body kits and headlights and stuff Diane just got a jeep JK love the video bro

Hey I’m trying to find out which stock kit you got in your maverick 88 video
You do great work, I like the way you think (example oil on gaskets 👍🏻) keep up the good work. “NOW BACK TO WORK, BRAKE IS OVER” 😂………⭐️⭐️⭐️⭐️⭐️

How are things after replacing sensor? So far we have done cap, thermostat and about to buy a new radiator. Sensor would be much cheaper lol.
I like your video and will try this, but I'm now interested in the very last part you touched on about the TPMS light and running 35s.
Just bought a 2015 Wrangler and it has 35s and the light will not go away. Can you comment more on this and why the light wont go off?
If the sensors are all still good and transmitting, then just have the tire size relearned at a shop.
Get JScan and you can change the tire sensor perimeters or even completely turn off the TPMS. You can also re do your tire size while you are at it so your speedometer is correct and your shift points are where they are supposed to be
Yoooooooooooooo
Thank you sir !!!!! Just saved me a bunch of money 🤙🏻
Just got a jeep and it is at dealer for overheating....I was thinking thermostat hopefully was problem and not a watepump issue.
Same. I take mine in on Monday. Mind letting us know what they tell you?
JScan to set your tire pressure parameters to your choice or even turn the damn thing off.
Going to give this a shot. I'll let you know.
Thanks for the info. Good video

hello greetings, I bought a fan on ebay and the computer does not recognize me what can I do.
Thanks that was helpful
Was there a code thrown aswell on the truck?
Genius!!! Thank you!!!
I think I blew my oil cooler or coolant hose that connects to it because I didn’t burp/bleed my system after I lost coolant due to a heater core leak.
What do you think?
Definitely going to subscribe!
Best advice ever.
If you can please respond to my question when and if you get this.
Distilled water is 60c?! Maybe in China or Africa
Thanks great vid.
Got this same problem if I would have known Jeeps do this I would have stayed away smh
I agree lol
Hi my friend quick question why you changed the cooling temperature sensor does it has to be change in cause replacing the thermostat?
Yooo how’s the hybrid poplar
What's the name of the censor?
❤ perfect
I did everything you did, except I didn't change the thermostat. Got back in the car and the gauge on the dash jumped up to 190 .

Mine was doing the same. Completely drained, flushed and refilled it. So far, no problems
Was electric fan also running with temp going up also my heat is Turning on and going off as I accelerate I was wonder if it is a water pump
