Flushing and bleeding your coolant...

[Punisher]

Went out and bought these... And what I did was put the flush fluid in the radiator and run motor for about 15 minutes

Open package and find the right size T fitting for the hose and cut the highest point of the heater hose and add the T fitting on and tighten clamp that comes with the kit...

Remove the cap from the T fitting and put on the adaptor that came with the kit and put the water hose to it

Start your jeep and turn on the heater on high and then turn on the water hose to fluch out the nasty shit

Ran it for about 10 minute til the water started to come clean...

I turned off the motor and pulled the drain cap off the radiator and drain all the water out and then turned back on the water and started the motor again and let it flush out for another 5 minutes to make sure all the water was clean

Once its all clean I recapped the plug after all fluid was drained and started to add the Antifreeze and water til it started flowing out of the T fitting

Replace the cap and fill you overflow tank and you are ready to go...

nice one... thanks for putting this in writting

[bluedragon436]

Nice writeup... I am going to have to do this shortly... I wish I had a driveway I could just let that coolant run down... but unfortunately it would just stick around under my Jeep in my gravel driveway..I need to flush the heater core separately for now though.. just to get heat again... then once I know I can get the water flushed out and coolant added before it freezes, I'll flush the coolant...

Does anyone know if the flush stuff is any less effective if I put it into really crappy looking coolant?? Or do I need to drain the old stuff out, then fill it with water, add the flush stuff and then let it run for 15min, before flushing the stuff out?? Only reason I ask... is I'm trying to figure out if or how I can flush my coolant system while it is still colder than hell outside...

Nice write-up

Nice write-up. From the looks of the stuff coming out, it was do for one. :D

Well for your sake in the cold weather what I would do is drain most of it out then fill it with the flush fluid and add the rest water and start it and leave it running for about 15 minutes it takes time for the water to freeze anyhow...

Yeah def. was... I don't think my brother in-law used any antifreeze, Just straight water...
Not like you need antifreeze in florida but I like to use it as if it was to have a leak I could smell and see that it is the coolant problem...

[XJ408]

Great write up man!!!!!!! That look like :turd: and water!!!!LOL

[default83]

yup mine looked the same way. just a tip, i did this when i replaced the waterpump, but it kept turning brown, i had to flush the heater core by itself.

simply unplug the two hoses going into the firewall and run a water hose on one side of it until clear, then do the other hole.

[Mudderoy]

Very nicely done! The only way it could have been better would have been to issue "scratch and sniff" cards with that old coolant smell! :smiley-laughing021:

[907_jeep]

good write up punisher and next time you have to shit... please dont shit in your radiator..it isnt good for your jeep XD

happy trails

I could be wrong here (it's been known to happen LOL), but I thought that if you turned on the heater when you do your flush it opens up the heater control valve allowing the flush to clean the heater core as well.

[default83]

yeah that sounds right, but my cable was broke to open the valve, and i didnt know how to fix it at that time, i just did it like that, it was pretty easy.

cool deal, one more thing to add to the pictorial is how to "burp" the system which means to get all the air out... that is a PITA, Ive seen somewhere where a guy had the WIDE funnel with an attachement that hooked right into your radiator where the cap would go,
anyhow this funnel is as wide and deep as an oil drain pan and basically what it does is "VURP" your system... men we ALL know what a "vurp" is for those who DONT a vurp is when you burp and a little vomit comes up ... I know GROSS but anyhow your cooling system cannot get the air out without bringing up some coolant as well and what this setup allows is the coolant to overflow into this funnel thing and allow air to come up with it and this way allowing your coolant to drain BACK into the radiator and not wasting it by letting it hit the ground.

Cool , this is Definately on my list of Things to do. By the looks of how my cooling system looks,I bet it will be ...the same as if The day After someone were to have a long night....of drinking a 12 pak of Old Miluakees Best ...yeh,anyho Very cool writeup & cool pix too*

[jetboy287]

I have always been under the impresion that you need at least some antifreez or else the inside of your motor will rust and block your rad and heater core. Not to mention that it raises the boiling temp??

Im not too sure if theres a correct answer , But....when the time comes to get My Project on the road once all my metal work is done....I postively will be flushing my system and refilling it with 50/50 water AND antifreeze. Only because IMO it does seem to avoid rust,visually atleast.

Antifreeze does help a little from rusting but its mainly helps the water from freezing up north where the temp gets below 32 degrees..... I live in florida so I just like to have it so if I have a leak I know whats leaking :D

[TeXJ]

I know late to the party... Great write-up!!

Antifreeze is also a lubricant for your water pump. It helps with the seals and lubricating the fan blade for the pump. Do not run without antifreeze in your vehicle!

[Rayburne]

Good ideas on cleaning your cooling system but should add another easy item to your list. Remove your overflow/burp bottle and drain and clean it. It's always overlooked and the flushing method doesn't touch it. But by removing a couple of screws a one hose it's off and cleaned with very little effort. Just stick a spray nozzle on your hose and place it into the large opening and spray away while holding it upside down.

Its not the anti-freeze that provides the corrosion protection ... but the additives that are added to the anti-freeze.

As for raising the boiling temp ... Yes it does ... slightly ... It also retains heat when passing through the rad - compared to water ... So IMHO the raised temp benefit is not really a gain.

I Havent had antifreeze in mine in roughly a year. Need to do another flush and find out why my reserviour leaks no matter what,only about a quart per week.

[Steve2kXJ]

I reverse flushed my heater core first with water and compressed air isolated from the system. Good thing too, since lots of crud came out. Flushed until water was clear. Then put in some CLR with the core hoses elevated and let it sit in there for 10-15mins. -then reflushed it. Removed the air box, to access and remove the lower radiator hose. Flushed & burped the coolant system.
Made an 80%+ increase in heat ouput from the heater. Runs cooler too.

[1TUFFXJ]

I know this is a hell of a bump but I'm trying to follow this guide. Do you drain the radiator before you fill it up with the flush fluid or just throw the flush fluid on top of the old coolant thats in there?

[Brasscatz]

I would honestly drain it first. I don't have any science to back that up, but I drained my system and even flushed it with water for a while before I even put the chemicals in there. Just my 2 cents...

[slacker90]

justr did this to my 99 xj and it worked awesome thx man!!!

[ricky_Z]

do you have to flush and refill the coolant first before "burping" or "vurping" the engine, i know its a silly question but this is my first time attempting to fix my truck, i have a jeep Cherokee 1996 sport, if it helps answer my question, i would appreciate any help and guiding

[4.3LXJ]

Yours does not have the sealed system. No burping necessary. Fill it, run it to operating temp and then top it off and you will be done

[slvmart]

I'm not a EnviroNazi, or anything close. But as someone that has 3 dogs and a cat, just letting that anti-freeze run on the ground is not a great idea. I know that it creates a lot of problems, because now you need to somehow collect all that waste fluid out of the cooling system. Anti-freeze causes kidneys, animal and human, to start forming crystals that shred the organ. A very painful way to go, from what I understand, and anyone that has had kidney stones can appreciate.
Not telling anyone how to do anything, but just a consideration.
