Common BMW E46 Cooling System Failures
HTML-код
- Опубликовано: 30 сен 2024
- The E46 was an amazing platform with one of the best engines that BMW ever made as far as driving goes, however its cooling system wasn’t exactly rock solid. There are a lot of common failures that need to be addressed because the one thing you do not want to do is severely overheat an M52TU/M54 engine because the cylinder head will warp, the metal in the block will fatigue and the head bolt threads will pull right out and your cylinder head gasket will fail. Basically, you'll have a really bad day, so make sure you address all the problems I list in this video.

Jason, you are a trooper and still helping the E46 fanatics. Thank you kindly.
Recycle bmw key
Absolutely agree
hella trooper
First ! Glad you’re still making E46 videos! Thank you so much!
This man speaks the truth I have a 46s and have replaced every single thing he listed facts
Hard-core BMW guys get mad if you tell them about the cooling system, I dunno why. The water pump impeller is plastic. They deny these facts.
@@camryuser yes it certainly is from the factory or oem replacement. I replaced one on mine and it had a metal one in there that had a bearing going bad and it scarred up the block.

I have m54b25 and it is awesome car. Atemporal and so nice.
@@camryuser u pref a camry or a m54 xd
Great to see you back and making more videos on the E46 :-)
agreed!
One more thing to check out: the cap of the expansion tank. This thing can start to leak or (worse) it will stop releasing steam at the supposed pressure (2bar for the m54 engine). Cheap and easy replacement that should not be overlooked.
Definitely! GAS makes a great modified one.
Will also most likely save you from having to replace the expansion tank...
@@lp2565 THANK YOU!
@@lp2565 Exactly. I got one... 1.2 BAR if I remember correctly. Others also use (I think a 1.5 BAR) cap from e30, etc...
I do not think lower pressure caps do anything for the most part. Here is the thing: My experiments with the 2002 325i shows that the coolant pressure does not really ever go above about 1.25 bars. The pressure fluctuates in the 10 to 18 psi (0.69 to 1.25 bars) range during driving. The pressure is NOT regulated by the cap under normal driving conditions. The pressure fluctuates due to the micro-boiling in the cylinder head coolant passages next to the exhaust valves. This is the reason why I conclude that lower pressure caps in general are not helpful for the most part.
my E46 was serviced for the waterpump hoses etc about 60k miles. my waterpump detonated I now have the metal water pump
You should've mentioned the 2nd coolant temperature sensor. The one under the manifold. Because of its location it's a PITA to replace and should ALWAYS be replaced if you are changing the two hoses connected to the head of the engine.
The mechanic change my cracked coolant extension tank yesterday. He said the auto transmission oil cooler thermalstat is broken too. I think he broke it while he was removing parts. It is not like it was broken before. And he said i might be okay to run the car without it. Is it actually okay? It is so annoying everything just keep breaking.
I did everything he mentioned when buying a 2004 E46. The one big mistake I made was allowing the Shop to go with a Behr Hella Expansion Tank. (now made in China) It cracked after 1 yr. and my car overheated! Please do as Jason says replace these with a BMW OEM Expansion Tank period. I go mine from FCP Euro with a Lifetime Warranty.
What about Febi Bilstein? Is that ok?
What happened to your engine after overheating? Is it still working?
@@Videos-os3ccoverheating doesn’t necessarily mean he continued to drive it
Yes, The One Maine Weakness on BMW E46 is the cooling system!
I´ve already Replaced The:
1- Coolant Expansion Tank
2- Replaced the OEM Water Pump With Stewart Water Pump
3- all hoses & Thermostat Housing
4- And new Radiator
All At the Same Time :-) !
All are OEM Genuine Parts.
Great Video! Glad you’re still making E46 videos! Thank you so much!
And Thanks for all your Tricks and Tips on BMW E46 :-)
What were those engineers thinking of when putting a plastic hard line under the intake?
I had an E36 with the M42 engine and they have a plastic coolant line in that same location too, the one on mine split and the engine lost all the coolant, cracking the head.
Repair dollars!
Crucial Info Your timing is excellent. Have 3 E46's and you have been a Great teacher! THANKS for All your super shots and Editing!
My first time ever touching a BMW recently my coworker gave me a X3 which I gave to my sister, but before I gave it I did everything you mentioned including idler pulley, belt tensioner, front driveshaft, all four brakes and rotors, oil change, cabin air filter replacement and cleanup of all cavities that harbor dust and leaves. It took a couple of days because I'm not a mechanic but I read and attend RUclips University.
Bravo Bro you're a Great Giver! Respect!
Just wanted to say Thanks m8 ... from Australia. 1🇦🇺
I appreciate all the time you put in for others. ✌️
My bmw won’t start after I replaced the expansion tank thermostat nd water pump what might the problem be
I suggest that you go to "e46fanatics.com" there are plenty of solutions to problems regarding the e46.
Your E46 Content is GOLD!! You've already helped me replace my ccv system, power steering reservoir and lines, and some miscellaneous suspension stuff. Thank you. I really appreciate it.
Wow, you got so skinny I almost did not recognize you. Awesome change! :)
Everything fails on a bmw everything..lol
Hey my dude, I love your videos. I just blew the expansion tank on my e46 and you've been guiding me through replacing practically all the engine gaskets, along with the CCV while I'm at it. I was wondering if you had any suggestions for cleaning out the oil buildup in the M54 intake?
It looks like you've lost a bit of weight and I'm hoping thats intentional. I really appreciate your videos and would love more on the e46, but not at the expense of your health. Take care of yourself.
Very intentional, I've been working out every day since February. My advice on the intake is to not worry about it, because even if you clean it out, it'll go right back to being that way within a week. If you hate the idea of this in the first place, you can switch to the catch can. If you want to clean it out after that, remove the intake and go at it with soap and water and a garden hose and let it dry out, but even if it's a bit wet, that won't hurt the engine -- actually it'll help it because water/steam decarbonizes engines.
@@50sKid Great advice as usual! Got a blocked cat on the right side, no exhaust out the passenger side. Got any ideas to fix it or just pull it? Thanks again and you look Very Healthy...Cali sun is sweet!
@@petepenn1 Is your exhaust flap just closed? If your cat is blocked, you need to replace it.
You are make me very happe and when I drive car it I think about you
In summary: Replace everything.
I think the only thing he didn't mention is the heat exchanger for the transmission fluid.
P2183 rad temp sensor calibration? Changed lower rad temp sensor twice URO and yesterday installed Hella temp sensor. Same P2183 came back again? 😞
My car just hit 150k and im sweating bullets after watching this video because I'm the 4th owner and have no idea whats been replaced.
Change all the coolant parts starting with the expansion tank and hoses. If no BMW marks on the old parts you know you will need a re do of the system. Save that car from a heart attack!
Thank you God of e46
The only solution i found with dealing with these nightmares from BMW amd their over engineering and intentionally designed fail points for dealership revenue is to not buy BMW products anymore. I've owned BMW after BMW and i only found peace of mind when i sold my last BMW car for a more reliable amd better engineered brand. The ergonomics, use of space in the engine bay, and quality of parts has always been a migraine with the E46. Great looking cars, great base engine but the supporting systems of tje engine (cooling system, f'ing bullshit hydraulic tensioner, plastic everything, intake plenum that will inevitably start to disintegrate) made me steer clear of the "German Engineering" illusion. The most impractical car to ever do maintenance on. I've owned Toyota's, Saabs, Domestic, Japanese, and even the overpriced piece of crap out of England but the E46 has been absolutely the worst, and I've owned an LR3 which says alot.
im so glad youre back!
I changed my expansion tank at 107k miles and it started leaking again from the lid, so I took it back to the shop and the radiator was bad but it’s still leaking. Do you think I have to get my expansion tank replaced again or would it be something bigger than that?
Common BMW E46 Cooling System Failure Points: The entire system. Replace everything.
Thanks man! Applying most of this to my E39 530i. Also replacing the torque converter next week thanks to ur vids. Did the transgo regulator already!
Thanks for keeping the peace of mind & accurate info in the E46 community!
My list so far
Radiator: Mishimoto aluminum
Thermostat: Aluminum
Radiator hose: Silicone
Lower radiator hose: Silicone
The fitment of most any aftermarket coolant expansion on most ANY tank is POOR at the least. Just finished wasting 3 hours trying to get the OEM upper hose to seal / seat to the expansion tank / Radiator @ the junction just below the tank cap / filler. Thanks - RockAuto for wasting my time and energy. The variance on the aftermarket Vs OEM was nearly 4mm between the two - such that it was impossible to seal / seat the cooling system at this critical junction point. Thought I wasn't buying Taiwan Tony aftermarket ill fitting equipment from RA - but be forewarned - their aftermarket tank doesn't fit at all either!!!!! Also beware of the tanks supplied with the coolant tank cap - some are supplied with 2.0 Bar caps and some are supplied with 1.4 Bar Cap. Using the lower pressure cap (1.4 Bar) is my preference - I'd rather loose a little bit of coolant @ 1.4 Bar cap Vs having an 2.0 Bar cap and an exploded (or burst) coolant reservoir. Little info is mentioned (or specified by the sellers) about the variation of the pressure relief points (1.4 Vs 2.0 Bar caps) of the expansion tank caps.
Hi Jason! Hey quick question I did a cooling system refresh hard lines under the manifold expansion chamber thermostat electric fan conversion hoses lower sensor blah blah blah bled the system properly but the engine still runs at 101°C dropping occasionally to 98 Celsius it typically ran at 96 I can’t figure this thing out any thoughts thanks hit me back when possible! Also the thermostat was OEM but from O’Reillys I’m thinking maybe it’s not exactly proper I don’t know?
My e46 overheated last weekend and it looks like the thermostat packed up in the closed position resulting in so much pressure it took out the expansion tank, the radiator, and the hose between the exp tank and the thermostat, luckily the head gasket seems ok thankfully! All advice in this video is defo worth listening too.
I would do a leak down test to be sure
The EXACT same thing happened to me just a couple days ago! The expansion tank explosion was so ferocious it was almost unbelievable!
Just do the whole cooling system like I did
I have a 2002 BMW 325i and I have gone through and replaced every cooling part on this vehicle and still can’t get the fan to start on its own. I replaced the cooling fan fuse but don’t know if I’m missing something, can you help?
What about radiators for the 2003 325i..looking at a used one seller said radiator was a common problem
Hy my friend, im rodiyan from indonesia... i have problem with my e46 engine m43b19... my temperature in OBD after access menu no 19 point 7, show 105 degress but electric fan not ON in this temperature
And then im replacement waterpump, thermostat, sensor coolant temperature in lower hose and electricfan with oem part. But after that temperature still in 105 degress and electricfan no ON this position... can you help me for closing problem for my trouble?
I Replaced my radiator on a 2005 Bmw 325i , car was over heating one morning and I seen a big coolant leak , driver side, not sure what else to do the engine will crank but not start, is there a common fix?
Learn a lot from you on my E46 👍 👍
I have a 2002 325i my coolant is full it was half way then the weather changed from hot to cold and now it jus rised nd its full now it dont over heat but its popping up a coolant light now
Man my e46 did so great for like 2months I’m weak lol now it’s over heating and I don’t know where from but I will change sumthin 🧐
I need to follow this guy 👦 on here. I have 4 BMW's at my house 🏠, one is my female Cousin Rochelle's and the other 3 are mine. I need all this knowledge
Dude you look amazing! Hope life is treating you well!
Same failures here with 2005 m3! Glad that’s over for now:)
Check out Zionsville cooling solutions. Expensive but one time and done. Have it on my e46 and e39.
Where do I buy the rigid plastic hoses under the intake manifold? Though I had everything right after I changed my head gasket, but neglected those hoses
I have a 99 328i it’s overheating but no coolant is coming out. I also changed the coolant tank because it had already exploded and overheated so I changed it and it keeps overheating idk what to do
Tks i need this video
Why do I get p0128 I know what it is but why does it get stuck open it only last for 8month bought it at o Riley is it because they sell after market
Hay mate I have a question..iv changed my expantion tank thermostat housing water pump an radiator an expantion tank thermostat an the coolant temp sensor an the water level sensor..but my car still overheats..any ideas would appreciate it..an also my fan runs when the car is cold an stays on 10 seconds after I turn car off..my upper radiator hose blows out steam slightly to wen it gets hot..tia
that cracking of the plastic happens on most new cars... no idea why they persist on using plastic.
Jason - have you done a video on clearing the rear sunroof drains on an E83 X3 with the pano roof? I cannot seem to clear one of the rear drains and I am about to cut the drain line inside the rear hatch side panel to be able to get a trimmer sting in there to try to clear out the rear drain.
I hate cooling system in m43b19 i can't bleed it. Is boiling like crazy
Well said
I would add the HVAC heater control valve located right next to the firewall. I had the hose nipple on that crack off completely on my 2002 Z3 and instantly empty out my entire coolant system. Fortunately, I just pulled in to park. Had it happen a day earlier, I would have been on the freeway, and the engine would have been fried.
I like the radiator by Zionsville. It is welding artwork.
Just replaced the plastic tubes under the intake manifold on my 2001 (200K+ miles). I put this off because I was afraid to remove the intake, but watching your other video gave me confidence. And yes, the end going into head broke off. I had to use an expansion tool to pull out the piece. With the intake off I also replaced the four rubber heater hoses. You are GOLD my friend - GOLD.
Jason is Platinum Now!
Why go OEM when you can upgrade to a metal tank once and never need to buy another?
So if I take shit off and see the stuff old get it while I'm in there and have access
Your videos are smashing good with info! I changed and replaced every component in the cooling system in 2020 (2003 325i). Those hoses on the engine block are typically corroded as you say.
I would add for those who have the problem of a broken hose-end stuck in the engine block, there’s a great video of a z3 owner (same M54 engine) who has a hack for removing the stuck pieces. Basically - get a 3/4” tap and a 3/4” bolt. Tap the hose crud and then thread the bolt in and use elbow grease to pull the stick pieces out.
Absolutely your videos are the reason I just picked up a e46 330xi a few weeks ago. Had one before but got totalled a couple years ago. I just love the way they drive and handle. Bmw has lost the essence of the ultimate driving in my opinion. Everything now is just all about speed and sticking an M emblem on everything. It used to be an exclusive club now its just ordinary. Bring back the old ways of bmw for us older enthusiasts.
You rock, man. Thanks as always for sharing all your experience and knowledge with these cars. With all your DIY videos you get that anyone who's thinking to buy one of these cars decides to go for it and fix it by themselves.
Greetings 50sKid. 👊🏻
Can I take out the front license plate bracket and drive
Thank you Jason! My hard line under the intake started to leak due to corrosion. Replaced it around 190K. Now my E39 has 212K. Very easy to replace once the intake is removed.
Hello, may I ask if the leak was bad enough to leave you stranded on the road? I was wondering if these hard lines develop sudden crack like the expansion tank or do they develop mild leak at first?
Great to see e46 video 😍
One thing is collant system might eventually leak, but aren’t all the sensors capable of detecting this?!
And the only car I’ve seen significant use of failure prone materials (like plastic impellers and weak radiators)and failures in my 5 90’s cars have been on my BMW (E36), the others all had significantly more mileage (median about 250k) and only minor issues (apart from a broken gearbox design in me Kexus RX300) in comparison.
It is a German/BMW thing, for sure.
Are sensors able to detect a cooling system leak, is that the question? The only existing sensor obviously is the engine coolant temperature sensor, but by the time that goes up, it many already be game over for the engine. I have installed a coolant PRESSURE sensor in the upper radiator hose. My theory is that this pressure reading will go to zero if there is a sudden catastrophic leak. We have a pressure sensor in the air conditioning system, we have a pressure sensor in the oil system, we even have a pressure sensor in the gas tank. However, auto companies don't put a pressure sensor in the cooling system. But that is what I think you are asking for. And yes, if BMW used better plastic (polymers, rubber etc) then we would not be having these discussions.
They don't necessarily need to immediately detect the leak, just avoid the engine from overheating because of the leak. But even that evidently is too much to ask.
And it's not like the engineers didn't know about this, this was a problem on the E36 as well. If you know your design has a weakness that might cause catastrophic failure, the least you should do is add an extra sensor to mitigate it somewhat.
@@brynyard The engineers at BMW did not misdesign the system. The design is fine for the most part. The problem is that somewhere along the line, someone (the bean counters?) at the BMW specs plastics (and other materials) that are not up to the durability. The poor durability of automotive plastics seems endemic to several European auto suppliers, not just the suppliers to BMW. An extra sensor would not mitigate poor quality plastics.
@@emineid The spec for the plastics is done by engineers, anything else would be incredibly stupid as it would require a complete retesting of the design (and even BMW isn't that stupid).
Strangely no other European car manufacturers seems to have regular occurrences of engines overheating because of this "endemic" problem, so by "European" you probably mean "engineered in Munich for BMW"?
Since BMW engines tends to fail so easily if (or rather when) they loose coolant, adding a pressure sensor probably would be an idea (unless, of course, they do the same mistake as with the crank hall sensor on the E36 and choose a sensor that can't handle moisture and require you to disassemble half the car to replace it). If the engine is so fragile it overheats before the sensor detects this it might be time to start firing some engineers.
Bring Mir Werkzeug isn't a meme for nothing.
Fun to drive though, but I wouldn't own one outside the guarantee.
The e46 Community would never have enough of your videos...we need more hopefully more would be coming
Exactly.
Man you are one of the e46 youtube kings! Keep whit the videos, you are the reason for many of those cars to be on the road, you are a legend!
So True Jason has saved many E46's and us owners thousands!
I had the Stewart water pump and it broke after awhile.
Great video and a very good reminder for what is required if you want to drive around in somewhat reliable vehicle
Just for preventative maintenance, I replaced my water pump (Hepu) and thermostat. Should’ve stuck to a Wahler one although not caused any issues as of yet. Noticed the radiator had a leak so replaced it with a Behr/Mahle one, also Gate’s upper and lower coolant hoses and a new coolant temp sensor.
Even after doing all that work, the fan wouldn’t kick in properly, at times it would seem like it’s struggling for power. It would turn on and after a fifth attempt, it would finally turn on for a couple of seconds then turn off. After the fifth or so attempt it would run full blast. When the fan doesn’t run, needle goes towards red. Could it be the fan? This might sound silly, but could it be the battery since alternator is finding it difficult to distribute power or could it just be the electrical components on the fan?
As always, excellent content Jason. Keep up the great work!
Bleeding the rad after an overnight rest is crucial and even a little air in the system will cause it to run in the red. If your driving and running in the red, turn it off and coast till you stop. Let it cool down and refill with coolant before going on.
@@petepenn1 I believe I bled it well. It’s just that the electric fan doesn’t kick in some times, due to that the engine overheats. When the fan runs here and there, engine temperature remains in the sweet spot.
To any new E46 owners. This guy is the guru. Note all of this shit. He knows what it is about. Love the 50sKid. The Master!
Since I've bought my 05 330CI ZHP your channel had been a GOD send. A million thank yous!
Why is my engine coolant pressurised
Good video Jason and reminder for my next interval. This video was due for some. I've done this maintenance every 35k for peace of mind. I beat on my E46's cooling system from Cali to AZ to TX and to Vegas every month, sits at 151k. This is a must know and super easy to do for every owner with the M52TU/M54 engines. Please folks use OEM parts as he says trust me don't cheap out.
yep, mine just started overheating last sunday, going downhill. it was not even hot outside. so that tells me its the waterpump. it doesnt overheat at idle, but it does at highway speeds. gonna get that brand you recommended.
turns out it was the thermostat, but i replaced the water pump too anyway. just had this catastrophic leak 200 kilometers from home today. note to self: replace the expansion tank mounting plate when replacing the radiator.
Jason speaks the truth. At the beginning of pandemic, I did replace all of this except the two hard lines under the intake manifold on our 2002 Z3 Coupe with the M54. Now I’m thinking I should go back in and remove the manifold to get these two hard lines. Cooling system should be redone every 100k miles or 10 years.
Can I ship my e46 to you to do a tune up?🙏
i've a feeling that a leaking oil filter housing gasket and /or vanos oil line in the same area could be leaking oil all over those hoses that are underneath the intake manifold - if so, that would surely not be good for those hoses in particular. Also, those hoses are totally out of sight, and as someone else said, get overlooked on that basis.
What if the coolant leaks into the pistons?
It might have been implied but I would specifically mention replacing the rubber heater hoses when replacing the hard coolant lines. Might as well since it's easy when the intake manifold is off.
Definitely
Thank you Jason!!!
Perfect timing, i took out the manifold to change ccv and vacum hoses, plugs, and doing stage 3 cooling, changing all those hoses underneath the manifold plastic and rubber ones, also might clean the injectors, debating whether i should replace the starter while im there, but not sure yet
If the starter is old, I’d change it. I did 👍
I did. It was one of those "while you are in there" decisions. You did 90 percent of the work of getting to the starter, so why not?
Yup, do the starter… sooo much easier w intake manifold outa there, but still a “bear” to do, but you’re saving a lot of $ doing it yourself! AND - the best part is knowing you’ve done it right … not a tech at the stealership in a hurry to go for lunch!

2001 and my tank cracked at 60K. Coolant was replaced every two years with BMW coolant and distilled water. TEXAS heat did it in. LOL.
Don't wait! you do NOT want this failing catastrophically - You could loose the engine!
Hello Jason, do you know if the leakage caused by the hard coolant pipes is usually bad enough to leave you stranded on the road? I was wondering if these hard lines make sudden crack like the expansion tank or do they develop mild leak at first?

I thought the m54 was a hot engine, the thermostat opens at 97° anything lower than that isn't optimal temperature?

Hey Jason, have you tried a lower pressure expansion tank cap? Supposedly, the lower pressure puts less stress on those plastic components, so they last longer.
A lower pressure cap does not help for the most part. The pressure is "regulated" by how much local micro-boiling that happens in the cooling passages next to the exhaust valves. The typical actual pressure runs 10psi to 14psi in this car, almost always less than 1 bar. The pressure cap only comes into effect in a catastrophic event when the whole system is about to blow. Exception: if you overfill the expansion tank, the pressure will run at 18 to 20 psi, so don't overfill obviously. I repeat: In all cars, the actual running pressure is not regulated by the cap. The pressure is "regulated" by how much local boiling occurs in the cylinder head, so in effect, the pressure is not regulated but does stay several psi below the rated cap pressure for the most part. Interestingly, a 2010 Honda Accord will run 4 to 14 psi all day, sometimes zero psi!!! A Genesis G70 will run 14 to 18 psi all day. Every car is different.
Lots of engines run in the same temperature range, with a much lower pressure rating on the cap.
Haven't tried it myself
A lower pressure cap will do absolutely nothing on an E46 for the most part. I have run both the stock and the lower pressure cap on my 2002 325i. I have a pressure sensor hooked up to the upper radiator hose. The pressure readings are identical whether you have the stock or the lower pressure cap. That is because the pressure almost always runs several psi BELOW the pressure rating of the LOW pressure cap. The coolant pressure runs in 10-14 psi range for the most part. The pressure is NOT regulated by the cap (except when something goes wrong and all heck is about to blow up). The best preventive measures are: Replace the parts (expansion tank, etc) before they fail, and bleed the system properly (use vacuum filling system if available).
Great advice. I need to replace all those items on my e46. Thanks for the reminder.
My friend overheated his M54 twice and still drives it, everything seems fine he says.
That's surprising considering the M54 really likes to warp the moment it overheats
@@EasyAchiever65 That's what I said lol, he lucked out with that engine.
Many thanks! 🚗
Thank you for your thoroughness! I have done repairs to my 2001 325ci that I still can not believe I was able to accomplish. I would have to sell the car Years ago- if not for your videos! Grazie!!
DON'T MAKE THIS MISTAKE! The dealer replaced the original water pump and thermostat, as preventive maintenance, on my 2005 BMW 330ci, with the only one they could find at the time which was a German made MEYLE with metal blades, at 80k miles, but it only lasted 15 thousand miles. The bearings went out in it and since I couldn't find the plastic OEM due to the pandemic, someone suggested that I do the electric fan swap. So I bought what was suggested to be the best from fcpeuro and it worked well, I even gained a few horse power. But it only lasted until last week when my daughter borrowed my car to go out of town from where she called and said that the AC went out first and then the engine had overheated! I had it towed and the first thing I noticed was the positive wire from the electric fan was burned out to bare wires showing... the fan was out, and so was my engine!
My E46 N55 would start to run high temp after about 15 mins of driving. One day I noticed it started to climb again and my coolant expansion tank ruptured, draining all the coolant. I’ve since bought all new quick connect coolant hoses, new tank and a metal finned water pump. I have yet to install it all. Is it likely this will bring the car back to health, or is it probable that I’ve done significant damage to the head/head gasket?
Hey thanks for the info very useful. Had a question about if the radiator fluid just seems to disappear everytime I fill it but i see no leak anywhere what could it be

Why would my upper coolant hose just burst randomly? I've had my 325i 04 for about 3 yrs no prob. The dealer I bought from had the wrong coolant and they replace the reservoir and housing but idk about the hoses. Any one have insight?
Love your E46 platform content
I love it I love it
Hi. Could do with your help. Installed a new expansion tank on my bmw 330 automatic, now it won’t seal. It’s sits flush to the mountain bracket that attached to the radiator. But when filling the expansion tank with fresh coolant it’s just leaks outs.
What would you suggest!
