Cummins ISX - OverFlow Full? Spitting out Coolant?

[@KamionKing]

Thanks!

[@bigjermparadisetrucker7236]

Grateful you posted this! This video is worth more than gold!

[@jacobadam9872]

Christ I've been having this problem for the past year I did lots of things problem was always the same no boost very small heels truck would heat up crazy the only way my truck with Drive it's with the fan manual switch. And I always have so much water in the tanks couple michanic took showers under the truck now I know what's really going on just like the other guy they all telling me I need to do a overhaul. There is no water or coolant mixing with my oil at all not even a single drop so nobody knows what the problem is I bet you many know why this is happening but not to tell and we all know the reason. I'm a real rookie when it comes to Motors or cars or engines thank you very much for this video man you saved me a lot of money thank you very much

[@jabkaahmed]

Thank you very much u the best you saved me lots off money I had coolant going in my air compressor and everyone was telling me I need to do overhaul but I flowed ur steps and it’s the air compressor if it’s was not u I woulda been doin overhaul so thank thank thank very much so ur help u saved me GOD bless...

[@jacobadam9872]

Was ur truck overheating when driving on road ?

[@wesleyakeli3547]

How did you fix the problem coming from the coolant reservoir?

[@美国流浪]

I've been to several shops and almost all said they couldn't fix it. This will be my last test. Because I stepped on the brake compressor today and it did work. Like replacing the air compressor would be fine. Save me.

[@shanehorn8848]

So glad you shared this. I'm having the same issue, and was worried to death.

[@georgejungle7521]

I wonder how many engines got rebuilt because of that and once they got put back together the shop said, oh by the way your compressor was on its way out so we replaced that too. lol

[@interstatebullly3nyg551]

I went to a shop last week to do mu air compressor.. right away they started talking engine rebuild. I said ok. And left.

[@maximomartinez8596]

That's what happened to me ? And l still have the problem they did't fix the problem my engine was rebuilt. And right now l don't what's the problem.

[@nunyabuziness8421]

Best advice anyone can give is dont idle,dont beat the piss out of the truck and run the speed limit and things will last way longer. The faster u go the faster everything has to spin and everything has bearings and gears

[@kepasakolegi8871]

I have same problem in mine, high pressure, not oil mix , not smoke mechanic changed compressor bit still same pressure 😢😢 mechanic made co2 test as you and test was negative not co2 in cooler , what can i do????

[@Cdllifestyle]

Just swapped resevoir because it had pressure building up n ended up Founded def in coolant, how could that happen ?

[@BulletMcNugget]

DEF in the coolant? Never seen it. How can you tell its def?

[@Cdllifestyle]

Found out how.. it's a coil in def tank that keeps def warm circulating coolant most likely has hole n flushed everything.. red coolant looked like tea in 4 daya

[@scottellis8964]

Mines doing same thing and yet didn’t change colors . I replaced the compressor only to find out my pro me still exist .. I’m currently removing head to find out if it’s a blown head gasket ,

[@saidabdulle7329]

so if i have this issue next time first think i check will be compressor thanks for you're video bro

[@jeffcaldwell7146]

Did it puke out all the coolant or just a portion. Mine does the same thing but it didn't spit it all out. It sits just below the low coolant sensor.

[@perezh99]

I’m having issues with my Paccar man and after getting reservoir, coolant sensor, wire harness, and EGR replaced mechanic now saying it’s the head gasket 🤦🏻‍♂️ help !! Me could it be something else, they checked the air compressor and it’s good.

[@MarkyG39]

Mine gets hot and send a lot of pressure to my resovour ONLY when I’m going up a hill other then that it’s fine any suggestions ?

[@mrt-lz4cw]

Bullet McNugget thx for your video! i have the same issue with my isx cummins .

[@farmermatt629]

I have a ism that keep blowing bottom radiator hose off ... I was overhauled a year ago... it’s a farm truck not many miles since overhauled...and just had it in to get radiator flow checked because it ran a little hot... radiator failed and was boiled out cleaned... now after about three days of running hauling it drops bottom hose and dumps coolant... btw only Does it sitting still at idle ... I’m baffled

[@zanecrouse9837]

I am having this problem going on 2 weeks. It seems that I get the over flow coming out once I've been running and truck come to a stop it over flows and spits out coolant. Do you think this could be the issue? Check the compressor? Suggestions???

[@michaelwright1602]

Could be the compressor, injector cup or a liner depending on the motor, mileage etc... Do a search on testing the compressor here on KZbin, you can do it in a parking lot. Always rule out the compressor first. Test the injectors, you may have to take to a shop if you do not have the tools to test yourself. Then if that passes, check the block for exhaust leaks, I use the test kits from NAPA, around $50, if the liquid changed from green to blue, you have exhaust gas in the coolant... If you get a failed test on that, I would drop the oil pan, pressurize the coolant system to 20 psi and let it sit overnight, have someone with a bright flashlight get under the motor while someone bars the motor over by hand. You will normally hear coolant gurgling up at the head, you are looking for coolant on the liner walls, it will usually appear as small clear droplets. You see coolant, you more than likely have a fretted liner and it is in frame time. The head is a one time use item, and do not just do one liner, you will regret it. Liners, the block needs to be machined, or cut, and the liners shimmed to .0014 of an inch. Each hole should be measured for proper height. Look up the videos by Rawze.

[@jean-paulpanfiloiu1586]

What did it end up being? My isx15 started doing the exact same thing. When I come to a stop it overflows and spits out coolant and my reservoir drains triggering low coolant alarm.

[@lucylia8444]

What did it end up being Zane ? I am having this exact same problem to a T. Would love suggestions on fixing it.

[@maximomartinez8596]

That happens to me after a mechanic replace my air compressor but and then they told me that it was my head gasket and after the engine was rebuilded. Same mechanic and the truck still have a lot of problems after that.

[@urielgarcia9943]

I'm going to check this on my truck today. I have alot of pressure in my coolant and I just got a rebuild

[@frankchilla6907]

So I've check for carbon, checked air compressor, checked egr everything was OK, still have the problem, WHAT NOW?

[@thegarage6348]

I have a question,so you see when u tested the head with block tester you had to use pump to pull in compressed air,I tried on a prostar with Cummins but as soon I put the tester there is so much pressure I don't need to use pump,would it be bad reserviour because getting too much pressure on the overflow of reservoir tank

[@thegarage6348]

And the ink never changed color on my truck

[@redeemedmat2211]

Sorry overflow is not caused by an egr cooler that’s is usually low coolant so yeah my guess is oil in the water or air pressure in the cooling system due to an air compressor

[@kpb985]

It does if you are deleted and the weld leaks

[@TruckingWithKimlo]

Dang I’m having same issue on my international so guess I’ll do this test the weekend and see

[@carlosflores9882]

I have the same problem, but on 2012 T660 Cummins. It’s too much air pressure in the Coolant reservoir

[@zanecrouse9837]

What did you do to fix it? I have the same truck. Did you replace the air compressor?

[@renemarrufo7536]

1,500 for a compressor gasket ?

[@jacobadam9872]

the thing that you rebuild is the air compressor I thought the air compressor it's right under the air dryer or is that a different air compressor? If yes what's the difference

[@slimshady23brar]

No theres only one compressor which is always engine driven. What your referring to is air dryer with filter cartridge ontop

[@jacobadam9872]

I see. I notest u r the mechanic not the owner of this that truck. Where r u located i might come to city to fix my truck

[@jacobadam9872]

I just finished the combustion test and it never turned yellow or any other color and I did it with the truck on with the truck off with the RPM high over 20 minutesnothing changed collors

[@Ghostrydr1972]

How does coolant get into the air compressor?

[@CryptoMoonBase]

Usually the compressor head cracks, it’s like a small engine with coolant lines running into it, if it cracks you get antifreeze going into the air system and air pressurizing the Coolant.

[@RIDEorDIE1776]

Have a Sterling I'm working on same issues but no egr. Did head test color never changed installed new compressor still same issue? Builds pressure and spews from overflow tube minutes after cold start?

Wow! I thought a new compressor was more expensive. My boost drops a lil when my compressor kicks on I’m thinking it’s bad. Nice job👍🏼

[@gradoisx2348]

NOOOO your compressor is not bad, it will drop boost because your compressor feeds off of air thats in your intake manifold because it has already been filterd through the intake and compressed a bit by the turbo!

[@mattt3284]

There's the head and the whole compressor. One may only need to replace the compressor head gasket (s) or the whole head but not the whole compressor unit. Or a head rebuild kit. $1200-$2200 as opposed to $3500-$4500.

[@Jerzeyguy]

Should that overflow have coolant in it.

[@dgulley2094]

I had this happen, but it wasn't a dropped liner. the reservoir was cracked on the inside

[@scottellis8964]

And how exactly does that cause psi build up in coolant tank ? I get it’s cracked but that won’t blow coolant out the reservoir tank ..

[@Kevin-oo1qi]

Had this exact problem with a Detroit 14 liter the air dryer wasn’t purging causing excess pressure to build and bypass into the crankcase the vent tube showed excess smoke and pressure in the coolant problem solved.

[@47lilleybean]

So air dryer causes the same problem

[@yomofo97]

Is it normal for my coolant to bubble in the reservoir when it’s closed?

[@dannyg.817]

Nope, coolant dirty bc lines are dirty like filthy dirty, clean. Up the hoses change the coolant liquid all of it start new and check it out.

[@sswwaaf]

So what did you guys have to do a head gasket job or was it the compressor

[@jackmeoff2274]

Are you REALLY that stupid?

Compressor

Wouldn't that problem put coolant in air tanks

[@abdifatahosmanboqare3416]

I got the same problem. Did the head gasket a year ago since then replaced the air compressor but still air in the system. Engine also run less than 350k miles from complet over haul. Mine is series 60 14 liter

[@chairperchdohere]

Did u complete took out or just deleted from ECM comp, if is still attached the EGR cooler can still make the combustion pressure check the EGR cooler

[@arlenburgin2392]

Great vid!

[@tamipotirala6973]

Better drop the pan and check liners.i had my air compressor do that and ended up leaking past the liner in the cylinder

Yep mine too. Disconnect the lines from the compressor and see if it still pressurizes

[@jlc2600]

Could this happen with the mx13 paccar engine?

Definately dont see it as often on a paccar but i did see it once.. blew head gasket cause liner dropped. But paccar would be the safer bet, to me anyway

You get it fixed?

Happened to me last week. 350,000 miles. Motor locked up after i stopped to put in water. Shopped said slipped liner. I am guessing coolant leaked into cylinder while truck was off. Wish i would have known this before hand. Usually youtube is the first place i go to troubleshoot. Thanks Bullet.

[@vondet1]

EGR cooler does that too

[@redeemedmat2211]

It could also be the EGR cooler

[@fernandoarroyo1378]

What about if when you're engine is hot the coolant level goes down then when it cools down a bit the coolant level returns basically back to normal .....

I am having same issue with peterbilt 579 Paccar mx13 . What did you end up.

[@jgutierrez2438]

im having very similar issue on 2012 isx15. pressure builds within seconds after starting trk, same as here. with cap off coolant spills just like on video. ive changed overflow tank and caps. i didnt see signs of liquid in egr pipe area. what are your thoughts on air compressor rebuild kits? did block test (same model from napa) but liquid color never changes. when head, head gasket, or liner bad will it always have liquid change color on block tester? will a blocked up radiator do this?

[@BulletMcNugget]

well the way you can make sure 100 percent is take off supply to air compressor like I did in video and run truck. If it does not build up pressure, then you found your issue. In my experience, yes it always changed colors when the engine was the issue. Hasnt lied to me yet lol Uh idk about the rebuild kits, I get Cummins parts for good deals so I always stick to OEM parts and never try to rebuild cause lets say you get same issue back later down the line then youll be guessing again, is it compressor or is it something else this time so I just like to replace it with new parts the first time and forget about the problem for a little while... but thats just me.

And now the engine has all kind of failures and a lot of codes. So is something they did wrong on my engine? If somebody can give me an answer please? What can be wrong with the engine and what l'm supposed to do?

All depends what your codes and failures are. No one will be able to help without knowing what issues you are having.

[@jonathanwilliams4501]

If you put a water bottle on the little overflow hose/tube and it bubbles like an aquarium you are losing compression into the water system..looks like someone replaced head and head gasket on air compressor and it wasn’t a good job at doing it...

[@BulletMcNugget]

If you got coolant in the left side, you dont need the bottle, it already tells you you got compression coming into the cooling system, just gotta figure out where its coming from by running tests, etc.

[@kingjames8283]

This has got my curiosity. My Detroit DDEC 3/4 is spitting out coolant from overflow and also starts funny with a quick burst of white smoke for less than 3-seconds then immediately clears up and runs right on cold startup. I can see no mixing of fuel in coolant or coolant in fuel tank. Coolant is orange, fuel is green with no oil slicks in either. Is it possible for a worn out Bendix Tu-Flo 550 compressor to feed coolant to combustion chamber and exit via exhaust? My engine was professionally in-framed in June 2016 with over 250k miles since. The problem I'm having now with coolant forced out of overflow, funny start-up, and cloud of white smoke didn't appear until a few weeks ago right after my pro-shop installed six new fuel injectors. I took it back to them last week with this problem, they put it on dyno but could not replicate the issues yet they exist and I lost over a gallon of anti-freeze on a customers parking lot a few days ago. Some one asked if the amount of blow-by exiting my downtube was normal and my quick reply was, oh it's a Detroit, that's normal. Now I'm having second thoughts as it does appear to be more than normal. Thinking of putting truck right back into shop (3rd time in a month) for head removal and inspection of head, gasket, and liner protrusion. First I want to make sure it's not my air compressor doing this but it didn't start until after new injectors were installed.
