I buy my parts from mercedes when possible . 210 000 on the car . Thanks again for your efforts . You are a pro !!!!!

[@Veizuh_1.3]

great step by step video. might do it for my girlfriends 2009 smart for two brabus. whish they had a step by step video for my nissan 370z like this one. thank you a lot!! 😁

[@jesse.vr6]

Perfect. Solved all my headaches of bleeding it

[@smarte.r.1450]

08:20 GREAT TIP! Thanks clear and concise instructions.

[@hippiewithacowboyhat]

At the end, you said the bottom radiator hose disconnect was "Optional". Is that just a step to speed the draining ? If so, then the system will drain fully without removing the bottom radiator hose, it will just take longer to drain from the back plug ? I ask, because it seems the hardest part is literally the removal of the bottom front plastics. If a full drain can be accomplished without having to lift the front, remove the splash panel, and disconnect the bottom radiator hose, the job would be much easier. Patiently awaiting your reply. Excellent video and explanation. Thank you from texas !

[@ToyotaGR86Performance]

You could drain it from the engine side and get 90% of the coolant out. Then refill, drive for 5 minutes and repeat. Good enough at that point. Removing the radiator hose just helps get everything out right away.

Very good video!! I learned a lot!!

[@willorge]

Man! My hat is off to you! Really really really good job. I own a 2013, I have never done this, but I might consider doing it my self. I dont have to to lift the vehicle, thats the only bad part.... My question is, if its not the mercedes brand, which could be a replacement?

[@ToyotaGR86Performance]

Any aftermarket company will let you know what parts/consumables are compatible. Personally I just stick with OE parts just because they are generally higher quality and therefore I am less likely to have to re-do a job due to faulty parts.

[@willorge]

@@ToyotaGR86Performance It's a good point.... I'm gonna look for those online, if not go and find some generic compatible. Still gotta figure out how to lift the car. LOL.

[@glhrm506]

The capacity of the whole coolant system is around 1 gallon? Very nice and helpful video btw

[@neilmatheson8753]

Best video I've seen yet. I have a 2000 Smart Fortwo, gasoline engine. Had a small accident and repaired the radiator and tried refilling but no circulation. I feel it is airlocked. And information on the older models? I suspect that it should be similar?? Neil

[@ToyotaGR86Performance]

I don’t know exactly about the 450 models, but the theory is you find the highest point in the cooling system and that’s where the air bubbles will accumulate. If you can find any coolant hose, that’s very high on the system, simply remove it while you’re refilling and you’ll see air come out. Once you have fluid coming out, the air should be purged and you should be able to get it to cycle.

[@Alexandros-Gr]

Hello Sir, Thank you for posting all these videos. Have you adjusted valve clearance yet in your car? Would love to see a tutorial. I have a tappeting noise at idle but I'm not even sure if it's supposed to be normal. I was wondering if my valve tappets were worn off even though I have only 70000 kilometers on the counter. The car has been filled with 0w40 oil since the begining, that's what the dealer uses, but I'm thinking of changing for 5w30 API SP. Cheers

[@ToyotaGR86Performance]

I haven’t done it yet. It is due every 60,000 miles. My car has 49,890 miles. I am preparing to film a “b service” but the valve clearance buckets won’t be for another 10,000 miles for me. But, I’m just letting you know in advance, doing the valve lifter buckets is not a simple job that can be done at home with basic tools. It requires shims and specialty tools to take off the bucket lifters without damaging them.

[@therapistnaefieldtea6687]

Hello! I added coolant to my 2015 smart car today. Now it’s making a extremely loud gurgling sound. It was almost empty. Any suggestions for what went wrong.

[@MrMr123]

What engine temps are we suppose to have.... 30º last night and my Temps where 162º-177º feels kinda low when the thermostat says 192º.... What do you think? Air? No work has been done on the car

[@ToyotaGR86Performance]

The engine does not generate a ton of heat. 170 is pretty normal in freezing temps.

[@rabbitfootedkitty1339]

You can’t get away with using an airlift? I have a 451 and I want to replace the coolant as preventative maintenance this is very helpful thank you very much

[@ToyotaGR86Performance]

I can’t afford a vehicle lift. 😂 It’s ok, not that hard to get it done anyways.

[@rabbitfootedkitty1339]

@@ToyotaGR86Performance nononono the airlift is a vacuum tool that uses compressed air and the Venturi effect to create a vacuum of like -30 psi (I don’t know what that would be in Mercury or other measurements) in the cooling system to replace said vacuum with coolant. We use it at work all of the time and it seems to work pretty much perfectly.

[@ToyotaGR86Performance]

@@rabbitfootedkitty1339 ooooooh, you see I’m too poor right now for such nice tools. 🤣

[@regan44017]

Yes, vacuum filling is fine. Done several with no issues

[@davidbejarano9447]

Could you answer a question for me. I have 2012 I followed your instructions but reservoir still gets completely full. When I run engine with heater on for 10 minutes. I’d let the system twice, but always seem to have air still in the line. Anything else I can try?

[@ToyotaGR86Performance]

Check to make sure all of your hose clamps are properly secured. Once you bleed it the way I show in the video you should not get any air injected into the system.

[@davidbejarano9447]

@@ToyotaGR86Performance thank you for the reply question I had it in shop because I had a thermostat housing crack and they had to replace it after they replaced it. The car was still overheating. I told him if they bleed it because I watched your video they told me they did but when I brought it back home, I did the bleeding and got a lot of air out. This will be the third time I’ve bled it I don’t show no temperature lights on. They told me I had a cracked head gasket. How can I verify that?

[@ToyotaGR86Performance]

@@davidbejarano9447 there are KZbin videos what show how to do a blow by test. Or you can purchase a combustion leak detector kit from Amazon to test at home. Any shop that tells you the car needs this service or that service without showing you test results is a scam. If they say your head gasket is bad without having had tested using the kit I mentioned above they are just trying to empty your wallet.

[@yuidfbse]

Awesome video! Unfortunately my 2009 Fortwo is the CDI Diesel model and I can't find the location for the bleed tube near the engine's cylinder head became it's in a different place. So I took the chance and did the whole coolantflush minus the engine bleed and instantly the car overheated, meaning the water is not circulating. All info I find online is for the 1.0L gasoline model, not the Diesel🤯

[@ToyotaGR86Performance]

Sorry, but I am not familiar with the diesel.

[@johnstone2728]

@@ToyotaGR86Performance the diesel requires a vacuum refill otherwise you are screwed

[@ToyotaGR86Performance]

That’s good to know as I have never worked on the diesel variant and I do not think there is any diesel versions in the USA that I know of.

[@MakeGodGreatAgain]

Oh boy. I read on some smart car forums by several people that you're supposed to use G05 coolant on the 2009 Smart Fortwo Passion 451, but according to you and some other sources I'm supposed to use the MB 325.0 approved (G48) coolant. Can I still use the G05 coolant or will it cause any problems that you know of? It's past it's return date and I'd hate to have to go out and buy the G48 coolant if I don't have to. So annoying

[@ToyotaGR86Performance]

Do this… Don’t listen to anyone. It’s best to go directly to the source (Mercedes or Smart) and find out from them. Call your local Mercedes dealership parts department and ask them what coolant you should buy from them, I.E., what the spec is. Or go to an official website and look up the spec.

[@MakeGodGreatAgain]

@@ToyotaGR86Performance Thanks

[@KennethDaigle]

I had the same issue on that Vaccuum line, I don't think it goes to anything did you find any different

[@ToyotaGR86Performance]

I did not find any other spot where that would attach to. I am assuming it is a simple open-to-air line.

Yo ..it's my second comment ...while filling my coolant reservoir with plain water for locating leak I was surprised at the amount of water it took to fill up . I could not see a leak as the reservoir kept empying and I kept on filling . Finally water was commming out of the tailpipe as I was filling . Any clues about what is happening . No water is mixing with the engine oil , it's all pouring out of the tailpipe . Thanks for your time for this video .

[@ToyotaGR86Performance]

If it is going out of your tailpipe, that means water is getting into your engine, and into your cylinders, then going out of your exhaust valves into the exhaust system, and finally out of your tailpipe. If water is pouring out of your tail pipe, that normally would mean that your engine is completely toast. Does it even start? How does it run if it starts?

[@normandgallant8106]

@@ToyotaGR86Performance Won't start and so far no oil in the engine (checking with the dip stick ) . I think the air contionning system cause the engine to strain and overheated .
