Excellent video - thank you very much. I changed a lower radiator hose and was having overheat problems so I watched this video and it fixed the problem. Love this channel!
USING BMW coolant(personally any good quality generic coolant with anti-corrosive additive is fine) ....in a dirty bucket (clean bucket is a great idea) ..LOL
Yes you should be fine but why take the chance, 1 gallon of bmw coolant is $20 premixed with 1 gallon distilled water ($0.80) makes 2 full gallons of coolant thats def cheaper than buying generic coolant
So my e46 323ci is overheating, I didnt want to waste money and its never cold here in New Zealand so I poured water in (luckily) the water went to the tank on the right even tho the radiator doesnt have enough water.. when I bought it I drove it for 40 mins without it overheating, when I got home and went to to the shop it overheated 😭.. help?
I took my 325i to Firestone with a faulty coolant level sensor. They replaced the sensor and expansion tank both because they told me you could not replace the sensor alone which I have since found out to be false. When I got the car home it had a very bad leak. Took it back to Firestone they said it was the heater hose which they replaced. Got back home and the next day it had a very bad leak. Took it to Firestone again they raised the car up and showed where it was now leaking badly from the bottom left corner of the radiator itself. When I asked if they had bled the air from the coolant they said that did not need to be done. I wish I had seen your video prior to taking it to them. Thanks for posting very good info on this BMW.
Shops like Firestone charge you more than Beverly hills Lamborghini service. I'm not exaggerating. My boss used to keep receipts he found in junk cars from them and other similar shops because it's so insane
If you plan on flushing the coolant, would it be OK to use pure distilled water to flush the system first, then use the 50/50 mix to fill and bleed the system once the old fluid is gone?
When you flush with distilled water until runs clear, you will have mostly water in the system. So adding a 50/50 mix after will make it so there is way more water in the cooling system than antifreeze. I added a whole gallon of just coolant and a little more of the second one since the e46's hold about 8.5 liters and a gallon is 3.78. Hope this helps.
@@mbz4652 Depends if you live where its very cold than adding 60% cooland and 40% water is fine but for most people it should be 50% water and 50% coolant
that issue can be offsetted by then filling up the required amount of coolant first and then adding the water to full. Then you'll have the 50/50 mixture. Don't waste money on coolant to do the flush.
Or you can do a flush just like a automatic transmission flush. Just keep an eagle eye on your temp gauge. As soon as it rises from cold start position. Turn off engine
Brooke Curtis I believe they did. They just didn’t show it, but they used the bucket to get the mix then put back into original container to pour in, since it would be a mess pouring from a large open bucket.
@@dannynguyen9074 What you see them pouring into the car is the coolant they mixed. They put it back into the bottle because it is much easier to pour that than the bucket.
READ THIS if you are bleeding due to replacement of thermostat/water pump. You probably know by now that removing/reinstalling the fan on a BMW is easily one of the more frustrating jobs in car repair. When reinstalling, there is no room to get your fingers on the nut, so you have to use a wrench. Meanwhile even with the shroud loose there is so little room to get your hands in there to hold the fan level and get the threads lined up, and it's very difficult to put any pressure on it for the threads to actually catch. So you'll stand there spinning that bolt painstakingly slow forever and nothing catches. Dargh! The combination is enough to drive anyone crazy. I've always found that I can only do it by standing off to the driver's side and fussing/cussing for 30 minutes or so. AND HERE'S WHY YOU SHOULD CARE. The bleed screw on my 2002 E46 is designed to drip coolant all over the alternator and PS pump pulleys, which causes the belt to spray it in all directions. If you just replaced the thermostat like I did, you'll be freaking out that you have a leak, but you can't see anything because of the shroud. Then you'll remove the fan/shroud again just to get a look at it, and you won't be able to tell what the heck is leaking because everything is soaking wet. So my recommendation is to leave the fan/shroud OFF while you bleed the system. Stuff absorbent shop towels down below the bleed screw to catch most of the coolant. Replace them as you go when they get saturated. With the fan/shroud off, you'll have access to squeeze the upper and lower hoses as you bleed, without losing your fingers. You'll also have good sight lines into everything to see exactly what's going on. In my case, everything was dry and tight, so I could have saved myself a lot of work and anxiety by just leaving the fan off until the system was bled. Why on earth is there not a bleed tube that takes the coolant in orderly fashion down to the floor?
I've taken it off so many times it only takes me about 5 minutes to put the fan on. I wouldn't leave fan off because I don't want any overheating issues while bleeding coolant.
1. What if the thermostat is not in open position? (I'm pretty shure my 320i with manual transmission does not have electrical thermostat). Or will the car perform something smart apart from just engaging the electric pump, like a solenoid pressing on to the thermostat to let the fluid pass by??? 2. Most cars have 2 drain plugs. One one the radiator as you guys where using, and the second plug on the motor (my sister just bought this car so I don't have the clue on where tio find it yet). If you had been draining using both plugs you would not have had any green fluid left, now in the video there was plenty. (picture the 2 plugs being located on each side of the thermostat)
Have a leak in the system of my 2000 BMW 540i....seems like it's coming from somewhere close to the hose neck on the right side (When facing the engine).....what's what's your reccomendation.
Its your plastic coolant reservoir. Replace that with one off ecs tuning . Com. Then bleed and fill no issues. And dont buy a jeep lol ive had one it was worse than every bmw and got me stranded more than the bmws
Dude is right, that is the heater control valve, it has a simple job, it closes when you demand A/C and stops the flow of coolant through heater core. Do you really think a pump could be powered by that tiny wire? The only reason this bleed procedure worked is because he did not drain the block, so it is only a partial drain/fill. Not much air in system when you just drain the expansion tank and/or radiator. You need to start the motor to activate the belt driven water pump in these cars.
green coolant could also be UV dye. I put some in mine to track down a leaky oring/hose to get it sorted. and now after several flushes, i still have neon green coolant even though ive filled it back up with BMW blue and distilled water twice. LOL
Couple problems. For starters, you have nasty seal eating green coolant which has phosphates, the BMW blue doesnt. You mixed them which isn’t good. You need to completely flush the system out.. and the water needs to be distilled water, lacking the minerals like calcium that eventually clog the radiator and cause issues down the road.
At the moment my heater doesn’t work , meaning I don’t have any hot air coming out the vents . Do I still turn up the temperature to 91degrees to bleed the system ?
Next to the vent inside the car in the middle, there is a rolling unit that changes the temperature. It can b mistaken for opening n closing the vent , but it’s commonly overlooked
Next to the vent inside the car in the middle, there is a rolling unit that changes the temperature. It can b mistaken for opening n closing the vent, it is commonly overlooked
I have used universal green coolant from autozone for 5 years on my bmw 323i and NO issues. 5 years and No issues !!! its a 2000 and my sons first car, we bought it for $800 so I wanted to see if anything would happen with the cooling system, so far so good.
ThisIsSolution yeah dude I’ve mixed it with universal in my old 330ci cause I was low and in a pinch. Never had any issue for over a year. I sold the car and know the current owner. He has yet to have an issue either
@@itsyaboi7387 - They say every 50,000 miles its good to flush it out. Use 50/50 concentrate with distilled water. If you live in a colder climate, its 60/40 mix more coolant than water.
This is kinda non conventional, but run it 15 or 20 miles, park, crack open expansion tank till you hear it hissing, eventually youll hear a bubbling. Close it afterwards, let the car cool and add some more. Takes less than a minute, i had to do it twice, went from no heat, to heat when driving only, to hestiny properly
Hello friend. I have a bmw e46 320d 150hp of 2004 model. There is no coolant circulating in the heater valve pipe, which comes from the engine bloc and connects to the heatervalve. Can you help ?
I've watched a lot of these videos, but our BMW is a pain in the A to bleed the coolant. Almost looks like it has a bad headgasket with air bubbles and coolant overflowing while trying to bleed, but it's just huge air pockets in the system. I had to let the car run until thermostat opened up just like any other car but shut the car off and add coolant 3x. While revving the crap out of it. It's deceiving because the coolant tank can be full but the rest of the engine could be practically empty. If your struggling make sure your heat is coming out hot, if not there's probably still air in the system.
Yeah, the video does not show level after thermostat has opened. When filling cold engine, thermostat is closed so coolant just going into radiator and heater matrix. When engine reaches thermostat opening threshold then the coolant level will drop quite alot leaving not enough coolant in the system. This guy does not run engine when filling coolant ?
@Arnold Rimmer Yeah I'm sure they still had air in the system, not only the thermostat for the engine but also the thermostat for the automatic transmission, plus the waterpump isn't circulating. I think what he turned on was the small pump for the heater core to help when the engine is at low rpm i'm guessing.
@@Yophillips3272 Some engines have electric water pump which can help purge out air when filling with coolant. The engine stiil needs to be at operating temperature so the thermostat opens otherwise air still trapped in the engine.
Hi just want to ask something i have a coolant leak while driving (lower radiator hose) i call towing service but what caught my attention i started the car but the theres no reaction from the transmission while i put gas ( car is not moving) I really dont know what happpen or is there a connection? can this be fix? thank you.
Krystal Ramirez sounds like your out of transmission fluid. Car won’t go into any gear without it. Happened to me months ago and after replacing the some hoses and gaskets my 328ci was running perfect again.
@@eddie39216 I’m very late but I think you’re wrong, in his case most definitely had his belt come off/rip off and damaged the lower rad hose causing the coolant leak. That’s extremely common for this car
I bought a zhp and I regret buying a BMW. This car isn't mechanically friendly. Coming from working on Honda's and Acuras BMW, benz ect are the most horrid complicated vehicles not to mention what you have to do just to bleed the system a Honda Acura 3 minutes and you're done. I was changing the manifold on my zhp I don't even want to talk about it
I honestly don’t understand why people are suggesting that BMW coolant is the only available alternative?? You just need to make sure that you have HOAT coolant and distilled water..that’s it!!!!
Zerex G48 Beck Arnley Euro concentrate Pentosin NF Peak OET Euro Blue Napa Euro Extended Life Blue VW G11 coolant-Yes this coolant was used in VW's until 1996 except the VW calls it G11 instead of G48 Volvo G48 concentrate-This same coolant was also used in Volvo's until the 2015 model year. Recochem Euro Blue coolant These are all of the suitable coolants I can think of in a BMW.
no, a flush would require the radiator to come out so you can put a water hoses up to the cooling hoses, keep doing that until the water comes out clear. turn off the car and put it back together then start the bleeding process, i just flushed mine not to long ago but now im struggling to get the air pockets out
Hi If you replace with new all the cooling system components on E39 528i 1998 M52 engine and you don't see coolant mixing with the oil.... And you have rock solid hoses, what's would be your suspect for this. BMW dealer here in UK is telling me this is normal but they are exceptionally hard can't squeeze them? When I drive temperature is solid 94C but idling goes to 102 and looks coolant doesn't circulate proper thru the radiator to activate the viscous clutch /fan.
The cooling system is pressurised and will make top hose hard to squeeze, is normal. If too much pressure then the cap will release it. The viscous fan activates from the engine heat not the radiator. Check viscous fan is spinning good at idle. 102 is normal operating temperature. Over 120 then I start to panic.
@@arnolduk123 @Arnold Rimmer Thanks for your time! I noticed when the pressure is in the hoses the coolant doesn't rise in expansion tank just 20mm above cold mark (white /see through expansion tank) the viscous fan won't engage (it's brand new MAHLE clutch) but electric one will do instead. But if I released the preasure from the cap.. water rise in the tank and hose get firm but not rock solid.. AND THEN the viscous fan clutch will engage around 100C (before an electric one) and will drop the temperature to 94C. My observation is with less pressure better water circulation. Have to find why coolant doesn't rise in expansion tank and to find the reason for the pressure that not allowing coolant circulation and viscous fan not operating as it should. Viscous fan does react to the hot air that sucks from the radiator... It has a metal strip (in my case, some has spring) that when heats its moves and realise a gel that helps the clutch to engage and disengage whe the air temperature that sucks drop down.
@@shefketmustafa9228 If you dont have any overheating and you have hot air from the cabin vents then I can't see anything wrong from that. The viscous fan can fail and cause engine to "bog down" quite badly, I had one fail and engine ran like crap, makes a loud whooshing noise with engine RPM. Other issues are failing/sticking thermostat or broken impeller on water pump slowing coolant flow. Only quick test is to try a new expansion tank cap and see if it releases excess pressure buildup. These engines idle temps are between 95-115 so don't worry if stay in that range.
@@shefketmustafa9228 No leaks ? you could have a blockage or restriction somewhere in the system. Would require a flush with radflush or some other chemical flusher. If you sure too much pressure then get a sniff test for exhaust gases but you'd know that by bubbles in expansion tank with engine running. Cap is designed to release over pressurized coolant.
Guys, this procedure is incorrect unless you have a euro 320d. The gas e46 does NOT have any coolant/heater pumps besides the belt driven coolant pump. If you leave the ignition in the run position for an extended time (and the temp setting to 91degees) without the engine running, you risk damaging the heater control valve solenoid. To properly bleed an e46 gas coolant system, you must run the engine.
Are you sure about that? Where do you get this info? I can't find anything about that. Everything I've found shows that this is the proper way to bleed the E46 system.
i just replaced a radiator on a 325i and it keep pushing antifreeze out and bubbling after I cut it off and now it want stay running, did I do something wrong because the car had been running hot before I replaced the radiator

Love your channel bro very helpful but the "OK" always make me laugh great work though
are you supposed to unscrew the bolt from the engine on the passenger side to drain the remaining coolant from the,engine?
its to let out any hot air inside or bubbles. so the coolant can go in more deeper. i learnt this today
electric pump ? what are you talking about ? electric water pump ? e46's they have a regular belt driven manual pump... or am I wrong ?
I hear the auxiliary pump running, but don't see the coolant circulating. Any idea why that would happen?
I’m confused why you mixed the coolant with water in the beginning since you didn’t use it 🤔

All your video is very helpfull.Specially i have 2001 bmw e46.Thank you...
This man has saved my life and so much time thank you 😊🙏
This exactly what I being searching for thanks dudes.
Do you only put the fan on or also the engine?

Hose cooling system on a 2018 BMW X2
What if you have those plastic box keys?
I honestly don’t understand why people are suggesting that BMW coolant is the only available alternative?? You just need to make sure that you have HOAT coolant and distilled water..that’s it!!!!
Or just get PEAK euro formula literally looks exactly the same color and it comes pre mixed
Zerex G48
Beck Arnley Euro concentrate
Pentosin NF
Peak OET Euro Blue
Napa Euro Extended Life Blue
VW G11 coolant-Yes this coolant was used in VW's until 1996 except the VW calls it G11 instead of G48
Volvo G48 concentrate-This same coolant was also used in Volvo's until the 2015 model year.
Recochem Euro Blue coolant
These are all of the suitable coolants I can think of in a BMW.
Thank you so much!
If I don’t do this..could it make my car over heat?
Yes and no heat.
5:35 THAT'S THE ELECTRIC PUMP!!! I ALWAYS HEAR THAT I WAS ALWAYS THINKING ITS COMING FROM MY ALTERNATOR!!!! 🤣
this is also called a coolant flush?
no, a flush would require the radiator to come out so you can put a water hoses up to the cooling hoses, keep doing that until the water comes out clear. turn off the car and put it back together then start the bleeding process, i just flushed mine not to long ago but now im struggling to get the air pockets out
Do you still jack it up on that side if it's a right hand drive? Thanks
Troll question
No actually, a genuine question.
You guys are great
Thanks man you the real MVP!
My name is a Borat 😂
Hi
If you replace with new all the cooling system components on E39 528i 1998 M52 engine and you don't see coolant mixing with the oil....
And you have rock solid hoses, what's would be your suspect for this.
BMW dealer here in UK is telling me this is normal but they are exceptionally hard can't squeeze them?
When I drive temperature is solid 94C but idling goes to 102 and looks coolant doesn't circulate proper thru the radiator to activate the viscous clutch /fan.
The cooling system is pressurised and will make top hose hard to squeeze, is normal. If too much pressure then the cap will release it. The viscous fan activates from the engine heat not the radiator. Check viscous fan is spinning good at idle. 102 is normal operating temperature. Over 120 then I start to panic.
@@arnolduk123 @Arnold Rimmer Thanks for your time!
I noticed when the pressure is in the hoses the coolant doesn't rise in expansion tank just 20mm above cold mark (white /see through expansion tank) the viscous fan won't engage (it's brand new MAHLE clutch) but electric one will do instead.
But if I released the preasure from the cap.. water rise in the tank and hose get firm but not rock solid.. AND THEN the viscous fan clutch will engage around 100C (before an electric one) and will drop the temperature to 94C.
My observation is with less pressure better water circulation.
Have to find why coolant doesn't rise in expansion tank and to find the reason for the pressure that not allowing coolant circulation and viscous fan not operating as it should.
Viscous fan does react to the hot air that sucks from the radiator... It has a metal strip (in my case, some has spring) that when heats its moves and realise a gel that helps the clutch to engage and disengage whe the air temperature that sucks drop down.
@@shefketmustafa9228 If you dont have any overheating and you have hot air from the cabin vents then I can't see anything wrong from that. The viscous fan can fail and cause engine to "bog down" quite badly, I had one fail and engine ran like crap, makes a loud whooshing noise with engine RPM. Other issues are failing/sticking thermostat or broken impeller on water pump slowing coolant flow. Only quick test is to try a new expansion tank cap and see if it releases excess pressure buildup. These engines idle temps are between 95-115 so don't worry if stay in that range.
@@arnolduk123 new cap and thermostat from bmw deer!
New radiator, water pump and viscous fan.
@@shefketmustafa9228 No leaks ? you could have a blockage or restriction somewhere in the system. Would require a flush with radflush or some other chemical flusher. If you sure too much pressure then get a sniff test for exhaust gases but you'd know that by bubbles in expansion tank with engine running. Cap is designed to release over pressurized coolant.
Really love your channel guys!
What you need to use g12 or 11
Dr. Spliff g11
thank you
Hey my hose have a lot of pressure. Coolant keep flushin out when I leave the engine on. Any ideas why?
BOGAN DOG
I seen a video where it was a sign of a blown head gasket
@@John-en1vp lmao seeing all these 1-2yr late panicked replies to some of these crazy questions on hear has me rofl.
nice video
Thank you!
Bla bla bla bleed the system already
Hey Man , do not smoke when you service bmw at 2:05 .
Guys, this procedure is incorrect unless you have a euro 320d. The gas e46 does NOT have any coolant/heater pumps besides the belt driven coolant pump. If you leave the ignition in the run position for an extended time (and the temp setting to 91degees) without the engine running, you risk damaging the heater control valve solenoid. To properly bleed an e46 gas coolant system, you must run the engine.
Are you sure about that? Where do you get this info? I can't find anything about that. Everything I've found shows that this is the proper way to bleed the E46 system.
Source please? I’ve been doing it this procedure along
That is correct. You have to get the bubbles out by running the car, very bubbly
My 2000 323i e46 wagon has it. I believe I have the Canadian model.
I tried this and the electric motor on my car doesn't start so nothing is curculating what the name of the electric motor
I don't think he knows what he's talking about the thing he pointed at is a valve for heat to the vents
i just replaced a radiator on a 325i and it keep pushing antifreeze out and bubbling after I cut it off and now it want stay running, did I do something wrong because the car had been running hot before I replaced the radiator
Im just being curios,does the radiator cap on when the motor is idle?or off.What if i see more bubles do i need to unsrew the bleeder plug?Thank you.
Thanks for the video. Very helpful!
i love the color of that coolant i almost want to swim in that color
Thanks, super helpful
