When you're a Renix owner watching for entertainment purposes. But appreciate that this is done so people can learn how to maintain a vehicles coolant system which tends to get neglected.

Great info, tell me more about Renix... if people air down regularly then when they air back up it's like checking regularly. Tire pressure has a lot to do with cupping as well.
this happened to my car air bubbles in my coolant system. my shop didnt do this when they put my block back in.. so i brought it back to my shop they got rid the air bubbles been driving my car few hours no more over heating temperature doesnt go to the H any more stays in the middle normal temp now...since the shop messed up they did it for free of course...yay.
Doing exactly this is how I found out my Compass has a bad head gasket. The bubbles never stopped! It had issues running warm shortly after I bought it. I thought the thermostats were bad so I replaced those then did this. Then I realized it was running warm because it was low on coolant from pushing it all to the overflow tank & burning a small amount in the combustion chamber. Unfortunately I believe it was sold to me in this condition but I have no way of proving it. It sucks but oh well live & learn I guess. We have put about 10,000 miles on it like this. I just pump the coolant from the overflow tank back into the radiator about once a week & it keeps going. Fortunately the coolant is not mixing with the engine oil so far
I tried that with mine. My jk doesn’t overheat. It just gets hotter them normal when my ac is on. Still haven’t figured it out. I just don’t use ac at slow speeds. Next I’m taking my radiator out and cleaning it. It might be mud stuck in it. Idk. Lol just next thing on my list
@@FloridaJeepRides Gotcha! I live in Ocala and it does get pretty damn cold here but not freezing. Thank you for posting this video, your view count probably went up a whole bunch just from me watching it a million times to make sure I got it right. It fixed my problem! ❤️
Just make sure it's not a closed system. Should be the same depending on what engine you have. Basically you wanna make sure that there's not air getting trapped.
Stupid question. I have done this in my JK.. Question is with the funnel on and filled a little, when I squeeze the upper radiator hose air bubble form in the funnel, but I assume they always will by squeezing the upper hose with the cap open. In other words will there ever come a point when squeezing the upper hose will NOT induce bubbles?
So when I’m stuck in traffic, the temp goes up past the half mark and my heater starts to shoot cold air instead of hot air. When I’m driving, temp goes back to normal level and the heater starts to work again. Does burping the radiator fix this?
I bought the kit but the tip that goes in the rad leaks unless you take a rubber gasket from one of the extras and put it on the top of tip - ie. One one the bottom next to rad and one on top between the tip and medal cap -
If it's a sealed system it has to be filled from the highest opening. It's the radiator cap is non top then that's the fill point. Most oil change places can get the air out as well.
Hello! Yesterday i noticed my fan was running really loud, so i checked my coolant. There wasn't any in the resevoir, so i added some. Added too much & then it started overheating which it wasn't doing before. Removed as much as i could and got it before the max full line, but it's still overheating not long after turning it on & idling. Should i fry draining all the coolant & adding it back this way? O changed the thermostat back in January & haven't had any issues, no lights are coming on & other than the fan running, the car was driving fine before i added the coolant.
Anytime I have to add: I usually have to burp the system as well. You can do it by putting the front passenger side kind of up on a little bit of a hill or a car ramp. And then I just squeeze the radiator pipe to burp the air out. Always seems to help.
I have that same issue when parked or in traffic stop it get hot and the fan starts to sound very gogh but once I start driving it cools down and the fan turns off
@@FloridaJeepRidesthe engine is heating it up. What a half-brained response. Engines produce hundreds of degrees of heat, and water only boils at 210 degrees. If youre running the car without the rad cap, and the coolant reaches operating temp + hoses are hot, the unpressurized coolant will immediately start boiling over because the freaking rad cap isnt on it. Not sure why youd give a dumb answer to a logical thing. Hopefully this poor sap didnt just tear out his thermostat because of a failure to understand pressurized fluids and boiling points. You shut the car off before the coolant reaches 210 but make sure the thermostat was hot enough to open. You can use a temp gun to make sure the thermostat is where you want it so you can shut the engine off before the unpressurized coolant boils over. Ffs.
Read my prior comment, but your coolant is boiling over because the coolant is reaching operating temperature without pressurization from the radiator cap. This happened to me recently and no one gives a good answer to save their lives. They just say you blew a head gasket or the thermostat is bad. When the radiator cap is on and the engine is at temp, is the upper radiator hose stiff? If so, your thermostat is working. Just for reference, your radiator cap holds 18lbs of pressure. Boiling point of water typically increases around 3 degrees per pound of pressure. So when you pressurize the coolant (due to the rad cap being on), you raise the boiling point roughly 54 degrees for a boiling point of 260 degrees which is (by design) the redline mark for your coolant gauge. Hope this helped, and maybe you didnt need this information because you got it fixed.
If there is air in the system it can cause issues. Burping get the air out and make sure the system is flowing. Not too sure on the science of that so if someone wants to add some info feel free.
That’s still didn’t tell me where to add coolant if I just need to add coolant. I’m not even sure if I’m looking at the right reservoir. Why can’t I find a simple video that just shows me how to open a lid and poor cooling into the ride hole?????
When I add violent and burp the system I add it through the radiator cap. Not when it's hot of course. Then after I'm done with that I fill the reservoir.
Thank you very much sir. Was having heating issues with my Jeep and this fixed my problem. Quick and easy thank you for the help
You are very welcome. Glad to have helped
Great information, I’m having that exact problem with AC ON, I’ll try this first , hopefully it’ll do the trick . Thank you !
Let's hope. The stress of overheating is real. It's been running at the right temp for over a year now.
Thank you for sharing your video tutorials 🙏. I will try once I have the burping funnel for the radiator. It was very informative. Sending my support
You are welcome! We hope to get Steve back on the trails Saturday- Starting off on a very easy ride. Tosohatchee

Its easy to do and saves you some grief. You can pull up on a slight hill and let it out of the top as well.

It happens a lot. it would be good if they made a air bleeder at the high point.

Good to do - all the mud holes can clog up the radiator and reduce flow. I replaced mine around 4 years ago.
If it’s at low speeds it’s probably just a bad fan clutch, worth replacing they’re cheep and easy to install
That’s the full strength Zerex. Is it ok to just dump it in without diluting it?
Most of the time I have some water in the system to thin it out a bit. In Florida we seldom get any hard freezes.

Does your jk have the bleeder screw?
Not that I know of.
Why would the air get into the cooling system in the first place? Just curious. Couldnt it be exhaust gasses from a leaking head gasket?
If you change out your fluid- or in my case the thermostat case got a small hole.
If it's a 3.6 Penstar ,
Your oil cooler is leaking...
Id bet on it
Did it stop the overheating?
Yes it had been running much cooler.
Would this work on a Grand Cherokee? Im assuming its got a similar system
Just make sure it's not a closed system. Should be the same depending on what engine you have. Basically you wanna make sure that there's not air getting trapped.

Make sure the Jeep is on a slight hill so the opening where the funnel goes is at the highest point of the system. Ramps work well.
Before doing that do you need to take out some coolant first ? Or no?
I did not take any out. I just got the air out and its been doing fine.
So when I’m stuck in traffic, the temp goes up past the half mark and my heater starts to shoot cold air instead of hot air. When I’m driving, temp goes back to normal level and the heater starts to work again. Does burping the radiator fix this?
If there is air in the system it could be an issue. Fans should pull the air through but if an electrical fan is off the ac won't work right.
Don't you place your Jeep at an incline so that all the trapped air located towards the firewall makes its way forward and out the radiator?
Yes, I try to make the fill valve the highest point on the system.
Will this work on 08 jeep patriot?
Not too sure. If it's a sealed system it may be a different process
I bought the kit but the tip that goes in the rad leaks unless you take a rubber gasket from one of the extras and put it on the top of tip - ie. One one the bottom next to rad and one on top between the tip and medal cap -
I think I did the same. There were several adapters but one fit.
Great information as usual. Thanks for,posting. 👍
Thank you - Its a easy thing to miss. The funnel is on sale right now for $18.87 and works for multiple vehicles.
How does this work on my 2019 jeep renegade sport?

I did this and the fluid boiled out of the funnel after running it on for 20 min ...what does this mean and how do you fix that?
That might be a thermostat issue. Not sure completely. But definitely something is heating it up.

How the hell do you get the air out of a JL!? There is no radiator cap to burp
That's a good question, if anyone Has an answer we will post it.
Same process but using the coolant fill reservoir.
Hello. Im new here. So why are you burping your vehicle's system using this method ??
If there is air in the system it can cause issues. Burping get the air out and make sure the system is flowing. Not too sure on the science of that so if someone wants to add some info feel free.
When i do this fluid comes pouring out of the radiator
The funnel helps, I have used a 2 liter soda bottle too
That is neat
Thanks
I like to pat mine gently on the tailgate.
The new problem is when it hits 3500rpms it acts like limp mode.
