This video will help you check your antifreeze level on a Mercedes Benz S Series

[@Undercover_FE]

Hey Wayne, I appreciate your explanation for coolant leaks. I think it's important to note where the common leaks are in this car. There's a main coolant pipe that fails behind the engine (happened to me) and is the most common leak on this car. You will never be able to see the leak by looking under the hood. Also, the reservoir itself leaks near the bottom (by the main hose). This can be visually inspected. The thin pipes that come out from the reservoir to the engine will probably break when if you replace the reservoir, so have those two pipes handy (also happened to me)! Lastly, there are hoses in front of the drive belt system that may leak. If they do, the belts can spit the coolant up to the top of the engine. Thanks for the video! Hope this helps!

[@WayneARobertson]

No Thank You for your comment. Much Appreciated!!!!

[@talal_alajmi]

Thanks. Don’t forget to fill the turbo coolant reservoir. Thanks

[@mateoleo1]

Do you mean that m278 have water cooled turbos? Is it that reservoir in the middle of engine?

[@Undercover_FE]

​@@mateoleo1 The reservoir in the center of the engine is for the intercooler.

[@mateoleo1]

@@Undercover_FE So turbos are cooled only by air and oil? And water in this reservoir is only for intercooler cooling?

[@Undercover_FE]

@@mateoleo1 I believe so! Gardevski swapped the turbos on his M278 for AMG M157. He claimed the difference between the setups (besides intercooler pump) is the turbo cooling. That is, the M278 is oil-air while M157 adds water cooling. I suggest you look into his turbo modification as it contains several pictures and information. Hope this helps!

[@talal_alajmi]

@@mateoleo1 Exactly these is the one

[@aspenly0127]

Aren’t you supposed to mix the antifreeze with distilled water 50-50? I think it says on the box.

[@WayneARobertson]

I never do that. I always buy from the dealership and pour the bottle straight in the reservoir. Until this point I've never had a problem.

[@aviondavis4019]

That’s is for window washer fluid sir.

[@lee.boy.dmv3177]

Yea bro u supposed to pre mix 50 parts coolant and 50 parts distilled water and it's a violet or blue color not pink

[@c.j.gutierrez6535]

It depends on what coolant you buy, some are premixed and some are not. Read the bottle you buy. Also depends on what year. I just found out 2014 and older Benz take different coolant than the newer ones. Just make sure to do your research before hand :)

[@danvelgtr]

Excellent , thank u Wayne.

[@WayneARobertson]

Your Welcome!!

[@tomhsiao2368]

hi - did you mix water (50/50) with the antifreeze coolant? or just poured as is?

[@WayneARobertson]

Just poured as is.

Do you mix it with distilled water?

Hey I have a question for you have you ever changed your lower control arms I went in for service and they recommended it I only have 52,000 miles on it 2015 S550

[@WayneARobertson]

I have changed it, not me personally, but my mechanic on other cars I use to have. Is your lower arm cracked or making noise? Did they give you a good explanation?

[@DugrandualFrank-dr1bi]

I have a question..I have a 2015 s550..it’s leaking clear fluid on the passenger side up under the car

[@luisarteaga-s5g]

Hello friend, is the color of the coolant red or orange?

[@WayneARobertson]

Red is the color I would say. To be sure make sure you go to the dealership to buy it first. They will ask for your VIN to give you the correct one

[@luisarteaga-s5g]

@@WayneARobertson ok thanks in the video it looks orange and in the base of my car that's also why the question

[@bigpressure00]

Where is the power steering fluid I’m hearing noises when I turn my steering

[@WayneARobertson]

Our cars do not have a power steering reservoi. You will need to put your car on a lift and have a mechanic turn the steering wheel while another mechanic check underneath the car.

[@bigpressure00]

@@WayneARobertson great lol thanks for the info I’ve been all over it looking for it

[@danvelgtr]

Wayne , will ordinary car anti freeze not suffice ? Didn't know it had to be unique to the car .

[@WayneARobertson]

Each manufacturer has their own antifreeze for their cars. If you step out of that recommendation, you will pay the price. This is from experience from my younger days.

[@juniordace1347]

So coolant goes into the windshield water fluid to keep it warm? Would it be common for coolant to come out of the wipers then? I feel like I saw some coolant come out one time on my w222

[@WayneARobertson]

Coolant is in the metal pipes that is in the coolant reservoir

[@JeffMedved]

🤨 You totally missed the turbo coolant reservoir on top of the intake (under the cover).

[@WayneARobertson]

Yes, as another comentor mention already.

[@itsthediabolical1187]

Thank you for this info I wasn’t aware it existed. Not only did you say it.. you told me exactly Where it was and I was able to find it and fill it. Thank you

[@Dan330i]

Is antifreeze coolent

[@WayneARobertson]

It's just another name for antifreeze.

[@a.m.ks.a808]

My car is s550 e 2016. There is a box under the hood that says system battery. I don’t know what it contains, and there is red water in it. Can you help me?

[@WayneARobertson]

Sure, what do you want to do?

[@a.m.ks.a808]

I feel that the liquid inside it is deficient. Should I add more and what kind of liquid is this?

[@a.m.ks.a808]

Is this fluid related to the battery or the radiator?

[@WayneARobertson]

@@a.m.ks.a808 I would assume the radiator but to be 100% sure, I would call your Mercede Benz parts department or just visit a local MB dealership parts department and ask them, better yet take a picture of it and show them. It definitely time well spent if you go in-person.

[@a.m.ks.a808]

@@WayneARobertson Thanks, I will visit them soon

[@ilhommuminov708]

Could you pls check yr temperature when you driving your car is it abt 200 ? Thanks cuz mine showing 200 when I start driving my car same car

Yes it hovers around 200 degree
