[@pgreen9705]

A really good instructional video - from a non-techie person.

@pgreen9705 Thanks, like you say I'm far from a tech just a driveway DIYer.

Nice video mate coolant makes so much mess. My top radiator hose broke last week had to get a tow home first time i have been left stranded at the side of the road 😅.

Another great video Thanks again, and welcome back after a long time . Cheers.

[@TheBimmerFixer]

@Matthew Barnes Hi mate, thank you! Sorry to hear about your breakdown, all fixed now I hope?

[@TheBimmerFixer]

@Ansar Ali Hi Ansar! Thank you! Hope all is well with you? 👍🏻

[@matthewbarnes1561]

@@TheBimmerFixer yeah mate after that I changed out most of the coolant hoses still have two to do under the manifold need better wether first 🤣.

[@TheBimmerFixer]

@Matthew Barnes Thats good! Yeah tell me about it it's looking bad here for the next few weeks🙈

[@hightech3161]

Great video. If I were to only replace the expansion tank, should i still go through the bleeding process ? Thanks for sharing !

[@TheBimmerFixer]

@hightech3161 Hi, thank you! Sorry for the delay in replying. I would say yes just to be safe and reduce the chance of an air lock. 👍🏻

Thanks for the video worth watching,

@tivanher Hi, thank you for the comment and feedback 👍🏻

[@brucevenema5267]

Really helpfull video! I just have a question. Since a month or so I don't have warm air blowing trough the A/C. Now I know it could be a lot of things but could you help me out where to start?

[@TheBimmerFixer]

@Bruce Venema Hi Bruce thanks for the feedback! So I would say the most likely problem would be the heater control valve not working properly, I would start there first. You might find just flushing the cooling system will fix it. I was just starting to get problems with heat not coming from the blowers but now I've done the coolant flush and change its red hot! Hope this helps and thanks again for the comment 👍🏻

[@brucevenema5267]

@@TheBimmerFixer thanks man! I will try both the valve and the flush 👊🏼

Hello mate. I am new subscriber . Thanks for the great videos . I have just purchased E60, 530i . Your videos are very helpful in showing how to service and fixing things on the car. I do have a ? . In this video u cut out the bit when removed the lower expansion tank hose. How did u do it ?? I am trying to replace my tank but I am not able to get that large hose off. I have even tried pliers, it will not move

[@TheBimmerFixer]

@Wayne Watson Hi Wayne thank you so much for the comment and subscribing I really appreciate it!!! You're absolutely right I did sorry about that. So it's the same kind of of connections as the bigger hoses. There is a little metal clip/band that you pull and lift and the hoses should then pull off. If you still have issues please let me know. 👍🏻

[@waynewatson5437]

@@TheBimmerFixer thanks for the quick reply mate . I did remove that metal clip that goes over the hose and still no joy. It's like its welded on to the bottle

[@TheBimmerFixer]

@Wayne Watson Oh really! Hmmm that's strange Im hoping no-one has put anything like glue on there. Does it twist at all?

[@owen6118]

Good video. I'm doing this on a e63 630i but it's a bit different. Could you tell me please what is that pipe at the bottom of the radiator next to the one you disconnected? It's the only pipe I have and I'm not sure if I should disconnect it. I've already done the one on the thermostat

[@TheBimmerFixer]

@Owen611 Hi, thanks. Nice ok so that other pipe goes to the power steering cooler 👍🏻

[@owen6118]

​@TheBimmerFixer thanks so much 👍 I'll leave that pipe alone then. Cheers

[@TheBimmerFixer]

@Owen611 Yeah makes a hell of a mess 😂👍🏻

[@MeggieRei]

So if it is a bit different and the pipe shown in the video is missing like it is on my BMW, how am I supposed to do the flush then?… I’ve been on this one for hours but no luck whatsoever; all videos out there show this particular hose and nothing else. Any tips? Thanks.

[@AbdulHaq11901]

Hi, when you were doing the flushes, did you connect the hoses back up each time? Thanks

[@TheBimmerFixer]

@moizhaq5840 Hi, I did yes 👍🏻

[@AbdulHaq11901]

@@TheBimmerFixer thanks for quick reply. Seems abit of a headache but ok. Just a question. So each time you flushed it did u turn the engine on to temp? Or u just added the water each time and immediately flushed? Thanks

[@TheBimmerFixer]

@moizhaq5840 Yeah its a bit of a pain but a couple of times should be fine if you coolant isn't too bad. So I would let the engine get up to running temperature so that the thermostat would open then drain it. Just be careful putting cold water into a hot engine I boiled the kettle so the water was warm/hot when I filled it back up to flush it again. If you didn't want to do that you can just leave the engine for a while to cool between flushes.

[@AbdulHaq11901]

​@@TheBimmerFixeryes thanks. So each time flush you add 10 litres of water? Just thinking how to do that many times as kettle holds about 1.5 litres 😂 so would take forever aha. But yh i defo wana add hot water to protect engine. Also about running to temp. My gauge always 3 lines so idk when engined upto temp. Can i assume 10-15 mins of idling is fine to get it up to temp? Also sorry each time u added the hoses back did you have to put those metal clips back in? Just seeing where i can save some timr haha. Thanks . Also my engine is n53 but i assume its same as this?

[@AbdulHaq11901]

​@@TheBimmerFixeralso can i use normal tap water for flushing few times as i dont really wana use too much distilled water? Thanks

[@JamesLim-zu7cn]

Hello nice video..i want to ask, i have changing themostat and water pump ,expension tank...but i dont warm air blow at the A/C..now temperature at the rpm have 2 line.. could u help me what to do? Thanks

[@TheBimmerFixer]

@Jameslim-zu7cn Hi thank you! It sounds like you have a airlock/trapped air in the system. If you do another bleeding of the system and this should remove all the air. Hope that helps and fixes the issue👍🏻

[@JamesLim-zu7cn]

Ok Thanks.. i will do it..Hope all is well..Thanks a lot!

[@TheBimmerFixer]

@JamesLim-zu7cn Thats ok happy to help. Let me know if it fixes it. 😃

[@JamesLim-zu7cn]

​@@TheBimmerFixerHi.. is all m54 n52 engine same do bleeding like your video? ☺

[@TheBimmerFixer]

@JamesLim-zu7cn Hi its slightly different. I can give you a breakdown of how I do the M54 if you like?

[@razvan1927]

Hi man! I did this , I changed my coolant tank and then I put fresh coolant , I bleed it. Now my problem is that the temperature of the water is no longer reach over 95 degrees and is stuck on 75 degrees, that s not normal temperature of running, plus my fuel consumption increased 2 litres. I could be possible to broke my termostat by doing that operation or what could be the problem. P.S. the water pump is running properly…

[@TheBimmerFixer]

@razvan1927 Hey Man, I would say the thermostat is probably to blame and the engine not getting up to temperature would definitely increase fuel consumption. Changing the coolant and flushing the system wouldn't break the thermostat itself unless there was something already in the cooling system and that has wedged the thermostat open. Before changing the thermostat though I would give the car another bleed or two I wouldn't rule out an air lock in the system. Let me know how you get on 👍🏻

[@razvan1927]

@@TheBimmerFixer Thank you very much for your quick answer… I came with an update, my engine reaches 95-100 degrees but only after 3,5-4km of driving so it shouldn’t be the thermostat but my question is , is not taking to much time to worm for an petrol engine? Thank you again for your help!

[@TheBimmerFixer]

@razvan1927 Hey Man, ok thats good to know. I think that's about right mine is very similar to yours mine takes a few miles to get up to temperature especially in the winter. 😃👍🏻

[@jilliebeans]

At what point did you use the radiator cleaner?

[@TheBimmerFixer]

@Jolly Rancher I added it to the cooling system before going on a drive to get the engine upto temperature so it circulated then drain the coolant.

[@jilliebeans]

@@TheBimmerFixer is this different from prestones cleaner where you drain first then add it in and drive?

[@TheBimmerFixer]

@Jolly Rancher Yeah must be the one I used is designed to mixed with the old coolant and be drained all together.

[@UMirinBrah-f9v]

Why is the flush done on turned off engine? Also whats the point of bleeding on turned off engine also? Cant i just turn on the car till temprerature reached, take out the water, refill few times and then fill with coolant and be done?

[@TheBimmerFixer]

@DanailFilev-xl5gc It's all done to save a bit of time and to avoid putting cold water/coolant into a hot engine. If you put cold water/coolant in when the engine is hot you can run the risk of cracking the block or thermostat housing.

[@TrulyUniqueOne]

Hi is this process the same for the m57 engine?

[@TheBimmerFixer]

@casey bramley Hi, it's very similar but the bleeding process is different because the M57 has a mechanical water pump not electric so you wouldn't have to hold your foot down on the accelerator to trigger the water pump for the bleed. Hope that helps and thanks for the question 👍🏻

[@shadowboybass]

in my car this line at the rpm whont work.... you know whi? is alwai stai at 3 lines ...

[@TheBimmerFixer]

@shadowboybass Hi, it could be the dash or the temperature sensor. If it doesn't move at all when you turn the ignition on its probably the dash. Thanks for the question.
