Taken the extra mile to explain engine cooling and coolant types. Well done! We want more videos 😊

I now have a certification on passenger car coolant maintenance just by watching this video..... once. Thank you for the thorough details Good Sir!

Dexcool is a OAT (Orange), you can mix OATs but not IAT (Green) coolents. When you mix OAT with IAT it turns brown and thickens up into a gel that the pump can not move. Back in the 90's GM had head gaskets blow because people mixed the IAT with the new OAT. Universal coolent (yellow) is just a OAT that can be used in all motors that use OAT, but not IAT. If you mixed up say, Toyota OAT (Blue) with GM OAT (Orange) nothing bad will happen, only a color change. It's like mixing gas from different stations. Gas is gas, it's only the additive package that changes. EVERY gas station gets it gas from the same spot in the area! The diffrence is when they pump it into the tanker, the driver pours in the additive package for that station, IE: Shell, Chevron, Mobil, Esso, etc...

Very clean and detailed presentation of all steps to be followed for proper flush and coolant replacement. Many Thanks!

You're a very good teacher. This is indeed a very well presented video on proper coolant replacement. However, please wear eye protection when handling chemicals. Cheers from Japan!

I’m going to be trying this on the mrs car today. I’ve watched your videos before and found them very helpful. Looks like you’ve helped a lot of people. Cheers

Thank you for this video. It is ironic that most people probably don't realise how to do a flush correctly; Me included. You were completely thorough with your guidance. Hoping to follow this and sort my van tomorrow! 👍

Good information, two thumbs up. Your technique is better than mine. My technique is to drain from the radiator when cold, fill with distilled water, run the engine until thermostat opens and top off with more distilled water, replace cap, drive car. Repeat Around 5 to 6 times, over the week. When the drained fluid finally becomes clear, fill with fresh coolant of the correct type. Think I might watch some more of your videos now I stumbled upon this one, 👍 Edit: only do my lazy technique when there is no chance of freezing temperatures.

Spot on and thorough, cheers

I Intend to do my Cooling System Shortly On My Mitsubishi Shogun . Engine Temp started Running On QTR So I Suspect the Thermostat needs Changing So good time to do this .Very well explained Video 👍..

This is the best I have seen so far, thanks for taking the extra mile to include so much information and clear explanation. What do you say about manufacturers specification on OAT coolant that says it should meet ASTM D3306 etc? Does this really matter?

I wondered how to get passed that pesky coolant thermostat with cool water. Thank you, Cyd; you solved that handily. I now have no excuse not to flush the coolant in my 5 year old vehicle. You gave me plenty of incentive with all that rusty, scaly buildup that is inevitable if I don't.

Verythorough thankyou. There is no way a commercial garage would do all this. They would just drain. Refill and maybe flush. No way they would do heater matrix, which is always hardest part for me

Glad I randomly came across your channel ...all ways good to learn the nitty gritty.

This is such a good informative video. Deserves way more views!

Very informational video! Good and understandable explanation as well. Now I’m going to change my coolant too. Thanks 😊

Thanks for this video, Cyd. Have a nice summer!

Excellent video cyd thanks 😊👍

Thanks a lot for this detailed video. I am going to do the first coolant flush ever on my 12 year old honda this week and was looking for some videos on YT. Yours was the first one I found and straight it was the fantastic one. Subbed ofc :)

Thank-you. Excellent video! Luckily I have a C1!

Excellent as it is very informative and detailed.

Good video. Gave it a thumbs up. Although your belief of the three types of coolant is wrong. There's IAT (inorganic acid technology) the green old school stuff. OAT "Dex-Cool" (organic acid technology) all kinds of colors and the normal stuff now-a-days. Then there's HOAT (hybrid organic acid technology) in some newer vehicles, yellow or orange. Dex-Cool is an OAT coolant and the first OAT coolant. The only difference between Dex-Cool and all other OAT coolants is a copywrite name. The biggest issue with OAT coolants is getting air into the system, so all of your warnings about Dex-cool coolant applies to your engine, air and heat plus OAT coolant can cause fast corrosion of metals inside the engine and a thick mucky residue. So it's best to pull a vacuum on OAT coolant systems when filling them with a venturi device and an air compressor. Only way to be sure there's no air pockets in the system after refilling. Because all the troubles of Dexcool are troubles with all OAT coolants, mainly being air in the system. Gaskets and o-rings aren't really an issue any longer, as long as the right kind are used. This might've been mentioned elsewhere in the comments, I didn't read them all.

Great video as always 👍

Great video thanks a lot! One question, do you know where the coolant bleed valve/plug is on the Diesel CDI engine? I did a cooling flush on my 2009 ForTwo CDI but could not find the bleed point location that I know should be near the cylinder head to bleed the air out of the tubing. Now the car is overheating with the water not circulating and I guess full of air pockets everywhere. I've searched all over the Internet and the all the information available is only for the gasoline engine not the diesel. Thank you very much😊😊😊

Nice video as always mate thanks 🙏 Will we get the vacuum line video for the 93?

Just had mine done it garage. Guy did everything. Just recommended checking levels tomorrow morning and just top with Dwater. Failed to ask expectation tank or radiator

Thank you!

Cyd great video, Thanks. Does unused coolant have a shelf life. Bye Heck coudnt get that drain undone, Next to the water pump. Thanks.

Thanks

Sorry from italy numero uno top

Sadly most people haven't got a clue about preventive maintenance and have to go to Halfrauds to change a wiper blade so flushing a cooling system would be like brain surgery!

Thank you

Hi Cylone cyd, Thanks for your clear explanation. The copper washer around the coolant drain plug is the same size as the oil ring? So it seems and that is also socket wrench size 14. How many Nm should the ring be tightened? And the pipes you took out of the block, for the heating matrix, are those the two narrower ones on the block at the group of four pipes on the C1, 107 and the Aygo? Thanks in advance

where did you get your car ramps cyd and how much did they cost? could you leave a link for them? cheers

Back in the day I just dropped a liter of filtered water in my car :) Probably a bad idea haha.

Great video Cid, many thanks. Apologies if you've already covered this, but as the C1s do not come with a temperature gauge, do you think it's necessary to fit an aftermarket one? Many thanks Harry

Do I need coolant which Toyota approved? I have heard that it could cause water pump failure, if you use coolant which is not Toyota approved.

Did you take the H4 projector headlights out of this car? No good?

Hi,cyd,Any help with driver's door, citreon c1,metal (arm) makes clunky sound ,when you open and close door,have oiled it,but when you close door, you can here clunky sound, any Help, kind regards Mike. Norfolk 👍

Hello, which pipe Do i have to Disconnect for the Radiator to clean it With Water? 😅 <a href="#" class="seekto" data-time="470">7:50</a>

Silly question but where can I get a replacement washer from for the drain plug. I looked online everywhere. Thanks in advance

Which ramps do you use for the c1?

We cant see what your doing.

Mate why are your reservoirs full to the brim! That's bad! Don't ever do that
