Absolutely mental!!! No wonder this is the only video that seems to be available on the planet!!

[@nickmandleberg]

This video was absolutely perfect - the best tutorial style on KZbin. Thank you!

[@HaynesManuals]

Wow, thank you!

[@erenbesili]

This might be the best how-to video I have ever seen, thank you!

[@HaynesManuals]

You're welcome!

Question, if Im using a vacuum filling equipment, do I still need to fill and bleed the auxiliary coolant pump?

[@carcreationsyt]

Thank you, very helpful! I have the 2L, but on following the instructions and pressing the accelerator for 10-12 seconds, nothing happens! I tried various combinations of heat on and headlights, still nothing. Anyone have any ideas?

[@LakeLake123]

I know it’s an old post, but I’ve found on some F5X cars you have to start the engine for it to work. Basically follow the same directions, but after you press the accelerator for 10 seconds, release the pedal, then start the engine. You’ll know it’s working because the engine will idle high (~1300 RPM) for around 10 minutes, then drop to a more normal idle around 800 RPM

[@jzh0701]

This is a very good video, than you so much, do you have a video to change the thermostat and water pump housing? Do I have to remove the compressor? I really appreciate your help🙏

[@HaynesManuals]

There's no need to completely remove the compressor - just unbolt it and move it to one side without disconnecting the refrigerant hoses.

[@theguythatweird]

Thank you very much for this informative video! You did an excellent job explaining the ordeal! At the end, during the pump venting procedure, do I need to do anything else while it is running? Or do I only leave it on with the low beams and wait for the 12mins to be up?

[@HaynesManuals]

Just wait for the 12 minutes, then top up the system.

Thanks for the sub!

[@xavierm.9265]

Hi! Love your videos and I do have your Haynes manual. For my Mini S F55, I replaced the turbo (primmed), the cat, turbo oil lines etc. Given I had to detach the coolant lines from the turbo, I’m guessing that would give me an air pocket I would need to bleed? Should I follow the gas-pedal step Gents? Cheers!

[@HaynesManuals]

Yes, we would recommend that you carry out the bleeding procedure

[@bryson7813]

Why does this not apply to a 2019 JCW mini?

[@melindahorn161]

Thank you for sharing

[@HaynesManuals]

You're welcome!

[@dyccy7029]

During the 12 minute pump venting procedure after pushing down the gas pedal to 100% for 10 sec do you need to turn the heat on to max temp and low fan speed similar to you do during the regular procedure?

[@HaynesManuals]

The procedure in the video is exactly as Mini describe. The way I read it, the heat should still be set to MAX with the fan at low speed.

[@thefakeslimshady5380]

Is this tutorial suitable for a Mini JCW 2.0L B48A20 engine 2016 model?

[@HaynesManuals]

Unfortunately not. Our manual doesn't cover the JCW models.

[@MrAchilles113]

no mention of where the draing plug is underneath the car, anybody know?

[@ferryportia9442]

@@MrAchilles113 don't think there is one

[@ShininDraco]

How the hell do you get to the cooling pump hose without removing radiator

[@sespark]

I can't find a manual or video on 2014-2018 minis on your website. Did you take them? The latest model available is 2013. 😡

[@sespark]

Apparently you sell the manual in Australia and not the US.

[@Nanokillaz]

If my mini is a 1.5 L model, do I need to perform the additional battery charger step?

[@HaynesManuals]

Connecting a battery charger is only necessary on the 1.5L diesel, and 2.0 litre petrol models.

[@buckers9565]

@@HaynesManuals does the 12 minute bleeding process work on the 1.5L B38 Petrol but you just don’t require the battery charger?

[@TheChainsawMini]

I'm so confused where is the coolant draining out of??? He doesn't undo anything other than bleeder screw up top?

[@Chrisratata]

I think that's it at 3:30, he just showed that step well after it had already been drain out from there.

[@right.spot.fishingstore5191]

Do you have a video showing how to take the radiator out?

[@HaynesManuals]

Sorry, no not yet

[@EliSalomon-v4b]

engine oil has mixed with the coolant , now the coolant looks like milkshake.. what would be the diagnosis for this case? thank you!

[@ferryportia9442]

@@EliSalomon-v4b Possible head gasket leak

[@Chrisratata]

It's unclear to me why removing so much was necessary just to drain

[@HaynesManuals]

It seems long-winded, but this was the procedure described by Mini

[@TranquilityTerrace]

so, is it just me or is this video for FOOLS only? Where is the drain point? You did NOT show anywhere where to place the green bucket where the coolant drains to, there has to be something right? Please show us where is the DRAIN plug for the coolant or do we have to remove the lower radiator hose to drain it?
