Mini Cooper S R53 Overheating FINALLY FIXED | Cooling Fan Change and Radiator Leak

[@ericsalidbar1693]

Just noticed a week ago that the car was getting a bit hot and when I got home If I turned it off right away the reservoir would bubble a little I hooked up scanner and saw regular temps, I read on a forum to let it sit until fans start then shut off and no bubbling. I can’t do it every time I drive so I looked online some more and realized that only high temp fan was running and not low temp fan, I know it’s one fan but two speeds. So this must be the issue. I did test the engine block for exhaust leak cause my Audi had bubbling in the res tank but showed no signs of blown head gasket until I did a block leak test. I tested the block and it was fine so I was happy to see that. Also the plastic bleeder screw was previously stripped so I ordered a new brass bleed screw cause I read they strip or break very easy. Thank you for this video! Some one had told me that the whole fan had to be replaced which is obviously not the case.

You must live near the coast... I can hear the seagulls 🤭🤣 always happy to see mini repairs 👍

[@murf4bz55]

Great video. FYI a soldering iron, like one used to do stain glass, would work and heat the wire from underneath and let solder flow to the iron!

[@iankelly2110]

Nice job Igor neat and tidy and the right way to do wiring. the liquid tape is great I have seen jobs done with just a swist of the wire and a bit of insulation tape over it drive me crazy

[@CarsExposed]

Ian Kelly thanks Ian ... I’ve seen that aswell it never lasts ... cheers 👍👍👍🍻

[@GrampiesWorkshop]

How's she goin'? Nice repair. It's always nice when you can determine what the fault is and then prove it by looking at what is damaged. Interesting about the fluid leak. Must have been like that from the factory like you say. Thanks for sharing and take care!!

[@CarsExposed]

Thanks Mike yeah finding the failed part is the way to go ... Yeah the radiator is just over a year old I’ve noticed recently it was weeping a bit but couldn’t believe it was coming from the elbow connector , well at least seems to be holding for now with a thicker O ring 🤗🤞👍👍👍

[@LMAutoRepairs]

Well done! 👍👍👍

[@CarsExposed]

Cheers Luis 👍👍👍😋🍻

Great editing. Lots of work to gain access to anything in the front of that dude. Nice troubleshooting of the fan.

[@CarsExposed]

Thanks Wyatt 👍👍👍 Are you back home yet?

[@wyattoneable]

@@CarsExposed Yes, thank you. I have one more travel video coming then that's it.

[@keithmutore3723]

Where can I find you lol😂. Great work. I am having same issues

[@miguelalmarante]

I bought a Mini Cooper R53 2005 is overheating but I haven’t find the solution , I change the thermostat, radiator which was leaking also installed a brand new, my mechanic also suggested me to replace the spark plugs and Ignition coil and cables and the card is still over heating. I noticed the steering wheel is kind of hard to turn left o right, I looked underneath the card and the power steering pump does not have the liter cooling fan , and the car just overheat when I stop in a traffic light or to add some miles in the gas station . I have the hypothesis that maybe is overheating because of the power steering pump is not working properly and also because the fan is missing . Could you please give me your opinion? I would appreciate

[@Automotive_Solutions]

Nice one Igor. Most of those minis I've worked on for Aircon just cycle the condenser fan on speed 2 because that resistor is always blown.

[@CarsExposed]

Yeah those resistors don’t seem to last for too long , I was surprised about relay for speed 1 being commanded on for speed 1 and 2 , I’m not sure about the strategy there but it works 😊👍👍👍 cheers mate

[@gfccbgjxvhd874]

Thanks for you vidéo 👍

[@familieverhoeve7127]

Hello Igor, great video ! I have the same problem with the fan. I also bought a new resistor like you did. There are 3 wires, 2 red and one blue. I tried to see how you connected them, but its not quite clear. Can you tell me where the blue wire goes? The 2 red wires are clear. It looks to me as if the new/second hand one has no relay at all...I am not very good at electrics so is the relay gone ? And the blue wire connected somewhere? I hope you can help me out here...Kind regards from the Netherlands. Martin

[@Badgertronix]

There's not much room under there. Nice work mate, always plenty to be doing

[@CarsExposed]

You become an expert of front end service mode pretty quickly owning a Mini Cooper 🤣🤣🤣🤣 I feel like I’ve done it pretty much everytime I’ve worked on it ... Always plenty work around owning a Classic ish or maybe just old 😋😊🍻🤣👍👍 cheers mate

[@monkeytutz2]

I like the liquid insulation product you used on the wiring repair. I would suggest you try adhesive lined heat shrink if you haven't done so already. Expensive but great

[@CarsExposed]

Thanks mate , yeah good stuff I’ve used in the past 👍

[@Stanleys_Crochet_Workshop]

[@mvillano]

Thanks so much Please could you tell me the resistor value?

[@divisionbyzero7916]

Gutes Video. Eigentlich braucht man den Kühler glaube ich nicht ausbauen wenn man den Lüfter wechseln möchte. Du hast den Kühler wegen dem Leck ausgebaut?

[@sidewalkMCS]

i bought a new radiator, that looks very much like yours. upon inspection the o-ring was not at fit properly. it was totally dry and twisted, deformed like yours. i also noticed the groove around flange connection is like .5mm too deep, even if the o ring was fit properly, there'd be issues soon. these problems are common with cheap aftermarket parts. however i put some silicon spray to the ring, then applied silicon sealer around the flange, making the flange permanently fixed to the rad. no leaks so far.

[@CarsExposed]

Thanks for the feedback mate , aftermarket parts seems to be getting worse and worse in my opinion 👍👍👍

[@TheCowgirlNiamh]

Great job Igor! Great to get an overheating issue sorted! 🤗👍

[@CarsExposed]

Thanks Niamh yeah I was well worried to get stuck in traffic and warp the head .... all done now 👍👍👍👍

[@bigsmith009]

I have an 04 mini Cooper fans work as long as you activate with the scan tool but won't work off the a/c or from the car by it self??

[@hevendranarayansamy2793]

Hey just watched this video. Thanks for sharing. Does your mini not have an aircon? I noticed no aircon condenser when you stripped the radiator.

[@CarsExposed]

No A/C unfortunately 🥵, thanks for watching

[@jakubgriga5210]

hi, i have problem with mine r53 where the fan wont turn on even after I changet whole resistor. the fan turs on when I do it with PC. I can see that you have to cables for the fan. Is there a reason I have only one?

[@sidewalkMCS]

Brilliant work!!! Did you note the size of the O-ring by any change? Attempting the same repair myself soon, it'd be great to know the size if possible!

[@CarsExposed]

Thanks mate ... sorry but unfortunately I don’t know the size of the o-ring I tried different ones from my kit until I found one that fitted well 👍

[@sidewalkMCS]

@@CarsExposed thanks for the info! Managed to find a similar looking o-ring set on amazon.co.jp. Watching your vid made me so confident in tackling the job myself! Looking for more videos ;) Thumbs up from Tokyo!

[@mariocal328]

Hi great video very good. I saw my Mini r53 also starts fan at 105 degrees Celtius. And stops at 100 degrees. So I think it’s the second fan like A.C. I would like mine to start like at 95 degrees and stop at 90 degrees. You think it’s ok to start at 105 degrees because it is an lot of pressure.

[@CarsExposed]

I’ve seen lots of vehicles starting the fan at 105 , to be honest if it’s designed like this I don’t see a problem in leaving it 👍👍👍

[@mariocal328]

@@CarsExposed Yes but it seems like it wants to through te water out of the tank

[@sasaberbat7767]

I have a mini one 2002 1.6 90hp. the speed of the antifreeze cooling fan turns on at 112 degrees. antifreeze is as it should be, everything is ok. Is that all right ??

[@MechanicMindset]

Got to hate the Pokey Pokey 😂

[@CarsExposed]

🤣🤣🤣🤣 Naughty naughty 😁👍👍👍

[@hiresliving8114]

Hopefully you check your notifications 😂 My low speed runs fine. High speed does nothing. What do you think the cause of that is? Or do you have an idea of where I can start checking. I got my mini 05 S for $300. The axle was broken. I replace both axles and tie rods. Car ran fine, except it seemed to have a parasitic drain. I was wrong. It was the alternator all along. After I fixed the alternator now the car overheats instantly. I tested the fan, and only low-speed works. I'm guessing since high speed doesn't work, it's overheating. Idk. All I know is that this is a complete Frankenstein mini. There is so much crap tied to other crap that doesn't belong in here. Everything was fine until I changed the alternator. The belt is on correctly. Which is what led me to discovering the high speed isn't working. I have no idea why the car didn't overheat before the alternator swap, and now it does. Im lost. Any help would be greatly appreciated. It's such a small, simple car to work on, and yet I'm am utterly lost.

very nice!

[@2oldn2slow]

Brilliant !

Thanks mate 👍

[@TheGibby3340]

Nice Igor. It’s good to familiarize yourself with the cooling (and condenser fan if equipped) circuit...It will fail sooner or later. Cheers Pal 👍

[@CarsExposed]

Thanks mate I agree there ... recently I’ve fixed quite few overheating issues and a/c issues ... cheers mate 👍👍👍
