- In this video, I show how I jacked up the vehicle to safely remove the the bumper cover (fascia) to access the drain-plug (drain-cock) and drain the coolant. I also show my procedure to refill the system with a spill-free funnel. Note: Clear plastic funnels are also available to better see the level of the coolant if someone has to be in the vehicle to check the gauges and keep the engine spinning between 1500 and 2000 RPM. .
There was no need to flush and seal my cooling system with distilled or mineral free water since the 12 year old HOAT (Hybrid Organic Additive Technology) was not contaminated. Nevertheless, I stored it in a jar for recycling.
During the days following the procedure, I checked the level of the coolant in the reservoir and it was fine.
As always, your videos are very well done and "cook book" like. Other radiator drain videos show that you can remove the front right wheel, loosen/move the wheel well liner only, and have access to the plug (as recommended in factory service manual). NO NEED TO REMOVE THE FRONT BUMPER. Thanks for the great videos.
A lot of work for something that should be simple.
Here's a trick cut a groove in a 13mm (cheap) socket in the front to fit the drain plug, it can be 1/4 or 3/8 drive attach to rachte be careful not to break the plug. you can sneak it in, good luck.
I have an 08 Patriot and I love your videos on how to change & maintain. I appreciate you!🤙🏽🪶
I appreciate the in-depth guide! Helped me a bunch. While draining the coolant the coolant flowed out of the drain plug but not the peacock and the reservoir still has coolant in it. Can you offer any advice?
The radiator petcock valve doesn't have to be fully removed to drain the system. The plastic reservoir can be removed from its location. You can look at my video ''Jeep Patriot 2009 2.4L Serpentine Drive Belt Replacement'' ua-cam.com/video/_wg2biG08UI/v-deo.html
from 00:34 to 00:50. When the reservoir is relocated beside (@ 00:50) there is enough room to place a suitable container in the lower area, so you can pour coolant from the reservoir into this container. Other methods can be used but this one is easy to do.
@@mtlcarguy wow thanks for the speedy reply! Didn’t know it came out that easy; I wanted to flush the coolant system, but it was fine like yours and I need to replace the radiator fans for my issues. Stumbled upon another guide where the guy unhooked the hose and let gravity empty the reservoir. Definitely appreciate the advice and (hopefully not) but if I ever need to, I know where to go for serpentine replacement. Quality stuff and thanks again!
Well done I got a question how many litres of mix coolant jeep patriot need in to the system? I have to do the same in to my jeep patriot , and other question why I have to run the machine to apply the coolant? Let me know pls!
You explained very well thanks 👍
Q1: The full capacity of the coolant fluid system is 6.2 L and the extra goes in the coolant reservoir.
Q2: The 'water pump' is driven by the serpentine belt on the side of the engine. It has to pump the coolant to fill all the cavities in the cylinder head and in the cooling system in order to get rid of the air pockets and air bubbles.
I’ve been turning the drain peacock for an hour it just turns forever???
I am not sure, but if a portion of the drain petcock threads is broken, it is possible that the O-ring is stuck in the radiator drain. Assuming the locking threads are not engaged when you spin the drain petcock, the part probably slides in the stuck O-ring and is not moving out.
Even if the drain petcock is broken or not, I would spray some silicone lubricant in the space between the radiator drain and the drain petcock to partially lubricate the O-ring.
This should help to unstuck the O-ring and pull out the drain petcock in order to inspect it. If it is broken you can buy a new one.

👏👍
So to simply drain the radiator this is wtf you have to do .
An other option could be to disconnect a coolant hose under the engine.
Right 😂😂 all of this to change the coolant
If you remove the plastic splash shield or fairing attaches to bumper cover you have better access to peacock.Take a dowel or broom stick saw a slot the width of petcock in dowel to act as tool help turning it but don’t go crazy you now have lots of leverage.
i got an old socket, cut a 3/16 notch about 1/2" deep and use that to turn the drain plug. Such a stupid design
What happens if you do not bleed the coolant properly?
If there is a major airlock left in the cylinder head, the engine can overheat ans get damaged. This is why I used a spill free funnel to remove the air from the system. Sometimes small residual air bubbles are still in the system but eventually they are removed via the the 16 lbs relief pressure valve inside the radiator cap when the coolant is hot and expands. You have to check the level of the coolant in the expansion tank, it should be to MAX.
@@mtlcarguy i try to top up my coolant but bubbles starts to appear when the coolant reaches the operating temp.. just one after another. The reason why my coolant becomes low is my rad cap got leak. And i know i didt not top it up properly. And now i am wondering why my reservoir is full and coolant is not coming back to the radiator and i notice bubbles.

In normal condition, when the coolant temperature in the engine is cold or not hot enough, the two thermostats are closed and the coolant circulates in the engine via the water pump.
But, it doesn’t circulate threw the radiator system.
So, if there is any air in the engine cooling system, it cannot escape.
When the engine is running, the coolant get to 82 °C (179 °F) the primary thermostat begins to open and it is fully open at 95 °C (203 °F).
Then, the coolant can flow through the radiator to be cooled and the air bubbles can circulate and escape via the filler neck of the radiator.
While watching the coolant temperature gauge to avoid overheating the engine, you can run the engine between 1500 and 2000 rpm to reach a running temperature and to increase the flow of coolant and air bubbles in the radiator.
The secondary thermostat opens at 95 °C (203 °F) and increase the flow of the coolant in the complete cooling system.
This thermostat is fully open when the temperature is at 110 °C (230 °F).
In normal running condition, the radiator (16 lbs) pressure cap is installed and the valve opens when the pressure is too high to flow the extra coolant and regulate the air in the reserve bottle. Small residual bubbles will eventually be removed after running cycles.
The level of the coolant reserve should be checked during the following 3 or 4 warm-up and cool down cycles.
Coolant must be added if needed.
Note: Read the warnings about coolant, it is a dangerous product.
@@mtlcarguy man.. the time you spent replying and explaining about the process of bleeding the coolant system is much appreciated and i will thank you for doing that. You didn’t just help me with this comment but other guys also who is reading this.. thank you so much my friend. 🫲
@@mtlcarguy I thought bubbling in the coolant overflow tank was indicative of a head gasket issue?
Appreciate 👍
Just another example of why you should never buy a jeep. Other then the cradles rusting out & being made from recycled pop cans. What a genius way to put the drain plug. Remove bumper to access drain plug. Who designed this vehicle, 8 year olds ?
This vehicle was designed when Jeep was owned by Daimler-Benz (Daimler Chrysler). The GS platform was also designed with the help of Mitsubishi. On the other hand, even if the Mitsubishi Outlander used a variation of the GS platform, their drain plug is simple and easy to use. I found a Jeep procedure for the models 2010+ that described how to access to the drain plug from behind fender splash shield, but, it can be very problematic if the drain plug is stock like mine was.
I just did this on my mothers 2008 patriot. It is unbelievable they designed such a pos that you have to remove the bumper cover to access the drain. Chrysler engineering should be ashamed of themselves. I also have a ram 1500. I will never buy a Chrysler product again.
You will never buy a Chrysler product bcs it teach you to know your our machine 😂 it’s even better to remove front bumper to she how is your machine and if you have a crash you can remove it again and change yourself radiator and condenser, grow up 😂
Great guide, but you don't need to remove wheels, bumper, or liners. Everything is easily accessible without doing any of it.
I've heard you can remove the lower radiator hose to drain the coolant but do you know how accurate that is ?
