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

[@BeatTheD3viL]

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

[@CycloneCyd]

Thanks for watching!

[@kenjithomas]

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!

[@MrWilliam.Stewart]

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.

[@johnskarvelis6936]

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

[@CycloneCyd]

You'd never get such a thorough job from a garage, that's for sure.

[@liambaker7489]

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

[@CycloneCyd]

How did you get on?

[@TonyG-iu4td]

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! 👍

[@zahirahmed2498]

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

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 👍..

[@mikebolt9753]

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

Why, thank you sir. I would agree, but I'm too modest 🤣🤣🤣

[@joekonderla8842]

Thank you!

[@kris856]

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 :)

[@CycloneCyd]

Many thanks. Glad you found it useful. Do let us know how you get on.

he did not let us know how he got on lol =) @@CycloneCyd

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

Thank you

Thanks

[@vauxaholic]

Great video as always 👍

[@CycloneCyd]

Glad you enjoyed it. I hope the info is useful. I tried to make it comprehensive, because there are no other videos out there that give the 'whole picture'. I don't think I've done a monologue before either, where I'm just talking to camera explaining a subject. How did you find that bit, boring? engaging? interesting?

[@vauxaholic]

@@CycloneCyd I found the whole you talking to the camera part very interesting and engaging, you don’t talk a load of waffle you make your video’s straight to the point and give basic information of what and why your doing what your doing. Looking forward to following this information when I swap my coolant next month 👍

[@CycloneCyd]

@@vauxaholic awesome, thank you. I can talk the hind legs off a donkey, but that's the beauty of video as a medium - I can edit all the 'fluff' out of it, lol🤣

[@martinneumann7783]

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

[@CycloneCyd]

Thanks, you too!

[@troy3456789]

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.

[@CycloneCyd]

Awesome. Happy to be of help. There's no guarantee a flush and renew will stop you ever having a problem, but if you don't you can virtually guarantee you will. Stack the odds in your favour 👍

[@ThorGunnarIversen]

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

[@CycloneCyd]

Great to hear! Thanks

[@MrOikono]

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

[@CycloneCyd]

Yes, soon (ish)

[@MrOikono]

@@CycloneCyd thanks man

[@volt8684]

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

[@SergioDattilorr]

Sorry from italy numero uno top

[@alexe5461]

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

[@garrynutter860]

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

[@CycloneCyd]

As long as it remains sealed and stored in a 'cool' place and out of the sun, I think most makers quote a 5 year shelf life. I've used coolant well over 10 years old before with no apparent ill effects, but in this instance I would add a bottle of water wetter to the coolant mix to bolster the anti-corrosion package. amzn.to/3IIbAe6

[@jdejong341]

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

[@CycloneCyd]

Not certain of the exact spec, but at least 30Nm. I did mine F tight! The hoses are easily visible, follow them back from the heater to the block, but I think so, yes.

[@FlyingSpaghettiMonster2000]

Which ramps do you use for the c1?

[@ryanlike2162]

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

[@rem9xird426]

Hello, which pipe Do i have to Disconnect for the Radiator to clean it With Water? 😅 7:50

[@jonathanbell7752]

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

[@CycloneCyd]

I'd be very surprised if any garage did as thorough a job as I show here. Virtually no-one would be prepared to pay the labour for such a job AND garages operate on throughput - doing jobs in less than "book time" while charging by the book❗ Methinks you're too trusting!

[@philipbarham3499]

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

[@volt8684]

Use a copper crush one off e bay or motor factor

[@matraz10]

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.

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 👍

[@CycloneCyd]

If you mean the check arm: lubricate the arm using silicone grease when the door is fully open and swing the door back and forth. Repeat a few times. Also check this kzbin.info/www/bejne/oV7Wp5eEm7iHaKc

@@CycloneCyd many thanks cyd,always helpful 👍 Mike

[@gumpfx]

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

[@arthunterns]

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.

[@CycloneCyd]

They would say that, they want to sell you "their"* coolant at inflated prices. Buy a reputable brand and flush thoroughly and you'll have no problems. * - OEMs don't make their own coolant, nor oils. They buy from the large refiners and package it as their own. And then put the scarers on you with stories of failures because you didn't use their brand.

[@arthunterns]

@@CycloneCyd I put Motul coolant in the end. So far so good :)

[@vBDKv]

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

[@paddrivers]

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!

[@volt8684]

Rubbish, many people use these type of vlogs to help themselves… me included and I maintain 4 vehicles, always slightly different. Ever grateful to guys like Cyd

[@paddrivers]

@@volt8684 Your a member of a relatively small church . Just look on ebay at the amount of cars sent to an early grave with neglected oil / fluid changes people just drive cars into the ground . Ive been in the motor trade most of my working life!

lol

[@paddrivers]

@@CycloneCyd Very comprehensive and informative video as always Cyd👍.

[@volt8684]

@@paddrivers they should teach it in schools. Basic maintenance is very doable but these vlogs give confidence. Still don’t agree with your opinion so we have to agree to disagree. Its motor trader costs that prob deter people servicing their cars. I am 64 I have never changed my brake fluid on any cars or motorcycles. Never had a problem. Lots of maintenance is overkill. Each to their own and I drive to Spain twice a year in my old banger.

[@rodneythekingcobra]

We cant see what your doing.

[@BigDirtyBasterd]

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...
