I just had an oil cooler failure in a Cummins ISX in a Peterbilt. I cought the problem early on so the cooling system wasn't​ to contaminated. A local diesel repair shop recommend a coolant system degreaser and it worked awesome. It is made by VE Labs L-11 radiator cooling system degreaser. It is a 16oz bottle and flushed it out twice with two bottles of this degreaser and it came out clean even the overflow tank great stuff and it's very low sudsing detergent. Thanks for the videos they are all great.

I used diesel to flush oil sludge in the cooling system. I fill the cooling system entirely with diesel. Then i run the engine for 1 minute, Oil dilutes quickly with diesel. Then i quickly drain the cooling system. Afterwards i flushed it with water and detergent several times.

I've used both Cascade and Purple Power. I prefer Purple as it seems to rinse better. You're right about being time consuming. Depending on how bad the system is I can easily burn a day. Overflow tanks I remove and blast them with a pressure washer and Purple.

Thank you your time.all your videos are very helpful. God bless. You.

Perfect, Really perfect... I tried 1 : 9 - dish soap : water mix It worked great, but I had to run 3 circulation periods of clean water to get rid of the remaining soap inside...

Someone brought one of those junk Izuzu equipped 4 cyl diesels in the shop about a year ago that had been driven for months with an oil cooler leak till the hoses literally fell apart from oil. We fixed the POS but whatever we couldn't remove and clean was just a nasty slimy mess. I only had a jug of that ERA laundry soap that we used to wash rags with for something I felt would be safe to use. I flushed with a few cap fulls of that ERA in the system till it was hot 3 or 4 times and it actually worked very well.

I've used dawn after 2 separate oil cooler failures. It worked well.

Thanks for the video! I've been using cascade but I'm going to try the foaming type now.

Thank you for all your information you give on your channel. My uncle told me about Amsoil years ago win I got a brand new pick up.truck. I tried it and I fell in love with it. I started to use it on my semi truck and the used it in my 2ed brand new diesel truck I started with the engine oil, then the front and rear differentials and transfer case and then the transmission and then my coolant on my pick up truck. So everything on my truck is Amsoil and i’ve never seen such an improvement by just using a different lubricant than I have with Amsoil my locking differential locks, smoother, and faster than it did before in my transmission shifts like a CVT transmission it’s like it never shifts because it’s so smooth. So using OEM products isn’t always the best thing to use. And plus Dec cool sucks and I do not like it at all, and it is like a acid and sometimes will cause more problems than its trying to prevent. And Amsoil heavy duty coolant is great for any on an off-road heavy duty, trucks, passenger cars and trucks and heavy duty pick up trucks. and I have noticed win my cooling fan comes on it takes less time to cool back down then it did before on the exact same hill and I would say around the same temperature out side. You should try it.

I have been using cascade dishwasher detergent for 20+ years, it works great, however i am a marine guy. Large engines and keel coolers introduce a whole other set of circumstances. Anyhow, thanks for the video, will

I did change the oil cooler I use dawn. Drained for 2 times and my c 12 is nice and clean thank you. For u video save me a lot and was very helpful god bless u 👍

Dawn is pretty good at cleaning oil from contamination coolant systems. I work at a CAT dealership, we had a oil cooler failure on a 3516 power module (200 gallons coolant system), Dawn made the process so much easier.

I use Dawn works very well

AWESOME advice as usual. Keep up the good work.

Wow thanks for this needed this for my cummins

Thank you for this video. It helped a lot.

When there is oil or fuel contamination i like to overfill the system to let all the oil on top come out,rather than draining it and having it go all the way through the system

Thank you for the info. Happy Thanksgiving to you and your brother. ✌️

another great video purple power works great for me as well

Good and meaning full 👍

Ill vouch for simple green. Works well. Plus its biodegradable so its not as big of a deal if it gets flushed down the drain. For recommends using simple green when a powerstroke has an oil cooler failure.

Super helpful! I am going to have to flush a coolant system that is oil contaminated from a leaking head. I will be doing it tonight. May try dawn platinum

I wouldn't use regular purple power or simple green because they attack aluminum. There is a Simple Green Pro HD that is aluminum safe that would probably work good.

Excellent thank you

thanks

Can you go over the exhaust cooler on a c15 LDN prefix. Failures and replacements.

I've had good luck with cascade dishwasher soap . It does a great job on atf after you loose a trans cooler . Real common on refuse trucks

Hi.. thanks as always, What you recommend to flush the rislone radiator leak or any stop leak , i used once but later figured how badly i screwed my heating system and other places like actuators.

I have used Dawn dish soap and back flushed it out after getting the engine hot from the bottom radiator drain petcock and opened anti-freeze ports at the top of the engine .

Josh, sorry for the late comment but who supplies the airlift' tool for recovering coolant you mention in the video. many thanks for your knowledge and time in producing these great videos..

Great video! Question: do you have a view on Dexcool-I have a 6.5 Detroit diesel that has dexcool--everyone tells me to flush and use glycol..any thoughts?

I found one of the Air Lift device on Craigslist for $50. Now its time to test it out on my RV with the C9. I don't know if it has ever been changed and its 13yrs old. Going to use the CAT ELC. Don't know how much air pressure is need as my compressor is rather small. Hopefully it will work. Wish me luck. How many gallons of coolant in the C9?

Foam was added to cleaning products as marketing wank years and years ago. People liked to see foam as a visual indicator that something was happening (it was working). Dozens of tests since have shown that foam does nothing to actually help clean any better at all. Great video though, keep em coming =)

Engine C15 Accert 2007 Freightliner classic XL How important is it to use distilled water for a coolant flush? Would it be OK to use tapwater with dawn mixture for the initial cleaning flush? And use distilled water for the water only flush.

Is that CAT quick flush (4C-461) okay to use in non CAT engines? I am getting mixed opinions from people saying is will damage my engine block. Toyota 1HZ 4.2L diesel.

i just had oil cooler go bad. fix it. I used 5 gallons simple green to flush with 5 gallon of distill water. It clean the oil out. I add the coolant back into the system. Now the I'm getting diesel fuel into the system the next day. Coming back out the reserve tank.I replace all the the cups with O rings. I use a gallon of Cascade this time.I'm on flush # 2 just water some diesel is not all gone yet. should I add cascade again on flush #3.Use water on flush #4

Just fixed a hose on my down pipe that was sweating at the bottom top filled it to where it said cold full but then drove it about 10 minutes to the truck stop and had low coolant filled it again but now I feel like my coolant reservoir has more pressure in it than before???

I'm getting a boat this week that hasn't had proper maintenance done to it in about 4 years. The SOS analysis comes back good on one and in the yellow on the other. Should I just do a drain and fill or do a cleaning to it or both of them? They are 1998 Caterpillar 3176's with 811 hours each

Where is the cylinder drain by the oil cooler in a 3406e 5ek?

what if I have 6.0 Powerstroke that's pron to oil cooler clogging? General opinion is that Motorcraft Gold is garbage and I could flush it out as soon as possible to keep my oil cooler from clogging

how often do you change your oil,are how many miles.

I have a CAT C12 engine in my freightliner century. The operating temperature is around 180 F to 190 F. When I am driving truck loaded over 40k lbs (or trying to rev more) the coolant temp gauge goes up and down. From 185 to 195 and back to 185 ? Does that mean there is air in system or is it normal for CAT engines.

Hey! I need to change my compressor on a cat engine. To do so, where should I drain my coolant? Obviously trying not to make a big mess! Thanks!

I have a 2020 f350 dually, I’m doing a coolant drain and fill but I’m not wanting to use motorcraft. I know there’s still some left in the system. If I refill with CAT elc will it damage the system when it mixes up?

After draining the radiator and block of coolant how to refil the system and get rid of air pockets in the block?

Great knowledge, just curious, are you in canada or the usa?

Where are the coolant drain plugs for a Cat 3208TA?

This is old news there's more up to date radiator flushes available today. Dawn? Wrong move. You'll have bubbles forever lol.

I you ever tried CLR to flush a radiator

Can someone put a video for a coolant flush / change for a px ford ranger xlt . It would be greatly appreciated

I have a 2003 pete 379 with a c15 6nz. It has a coolant filter. But the bracket broke and the filter smacked off the front passenger side shock and got all dented up so I turned off the shutoff valves to it. What do I have to do to go about replacing it..? do I order a new empty filter and fill it with chemicals for the coolant? its a baldwin filter and i see it says something about ammonium nitrate on it or something? or do I just order the new filter with the bracket bolt it back up and spin the filter back on without adding anything to the filter? I can't find anything about it in CAT manual for my truck.

Which coolant do you recommend in a 3406c mechanical. Lots of Misinformation.

I’ve had good success with Tide laundry detergent.

Can you tell me where the valves for the supply to heater core are? Cat c12 2003

Sir im just only asking about c18 acert diesel engine the issue intercoolant low level alarm. I checked the sensor and tank level is ok. How to airlift

run the block heater if you need to warm the mayo...

how do i know if i am getting oil in the coolant or coolantto oil?

Your video did not tell us when to add the water or coolant back in. Should the motor still be hot when adding the cold coolant back in or should it be cold , below what temperature should the motor be when doing so. Thanks

Now I understand why Cat pays hourly, this sounds like a 4 hour affair

Dawn works great but it takes a lot of water flushes to get it out

I put a pint of synthetic into my cooling system. Oil cools, cleans, seals ,and lubricates. A graduate of Nashville Auto/Diesel College. Send the hate mail

How the cooling sistem works in 1988 low flow 400 Cummins please help my truck over heat

What about flushing green coolant out of a system that should have orange ELC in it? guy before me added the wrong stuff to my CAT 305

i have new oil cooler air compressor tested top end rebuilt {no liner work}.

I have a 2007 ford bucket truck with a cat c7. I want to do a flush something that would remove or break down any wood chips that might be in there any sugestions?

Can you run air pressure through the cooling system to flush out all the nooks and crannies.

Hey adept ape. I have vw diesel idi but mechanical fuel pumps are similar design on a lot of older diesels. Does atf fluid swell the seals? Leaky fuel pumps are a problem and online forumns suggest leaving atf fluid in the pump over night or mixing with diesel.

vinegar cuts rust and scale. doesn't damage anything. use baking soda to neutralize initial water flush.

I say DAWN.! I used it for years

Anyone knows, after draining from the block, flush out with water....fill..and drain again, but water is black, but not oily....wth is that? Flushed 5 times, still have black water coming out.???

Recently purchased a truck with a 2004 C15 motor and I noticed the coolant is green.. Does coolant brand/color have to be a specific brand or color? Thanks Josh!

hmmm/ heard that a preashure guard and air/ vaccumpump it out can get99% water out.... but not shure if it is safe for the cooling system..... cant find anything in the sisweb about that

So like an idiot without realizing i put engine oil into my coolant reservoir. Not a lot maybe cup and a half. How bad is that for a weatern star 5700xe?

Cat c15 will start run but only stay running when press on acceleration what the problem?

Use Thoroflush

Tapit setting c a t engine 6cylider how many Clarence

the video has more details but you didnt include the engine drain plug

how do you properly do a vacuum coolant charge in the system

I didn't know that engine manufacturers like Detroit or Cummings or paccar where in the manufacturing of antifreeze, I know that they're not somebody else does that and they do have antifreeze that does not have any water in it cost $34 a bottle, where does the build-up come in your engine that you have to flush out do you really know. You can leave a comment on my channel on any of my videos, and I will respond to you

I've heard beer works pretty good too, but what a waste

😩😴

too much work really unnecessary

So with the airlift refill. Will the vacum be able to suck, let say, 12 gallons back into the cooling system? I am flushing and replacing my short 2.5 and 3.0 inch hoses on my C15. No failure flush, just plain old simple flush.
