I recently did a full cooling system flush on my '99 328i. (Drained expansion tank, radiator, AND engine block. After draining the old coolant (not sure what it was but prob was the bmw branded coolant. I let it idle and for a little while with only distillled water 3 times and also put some...

I'm posting this because I've seen a few people struggle with hard pipe corrosion recently. A while ago, someone inquired about replacing them WITHOUT removing the intake manifold. Is that even possible? When I replaced mine, I disconnected everything. I can't even begin to imagine replacing the...

I discovered a couple days ago that both of the coolant hoses that fit beneath the intake manifold are leaking. Well, one of them is, but I'm replacing both just 'cause. Is there anything else that I should replace while I have the intake manifold off? (vacuum lines, for example) I don't want...

I recently purchased my second E46 in the fall of 2020. One of the first things I took care of was bleeding the cooling system since I was getting an intermittent coolant light and little to no heat (I believe this gave me heat again for a short period of time). The previous owner had stated...

Fortunately, my cooling system hasn't caused me any issues since my last post about it. However, I'm always wanting to learn more about these cars. I saw a thread somewhere on the internet about overfilling the coolant reservoir/filling it too high. My question is, where does the excess coolant...

hey guys, recently bought a 330ci back in August and I finally saved up enough for some tools and a cooling system refresh kit. Now I originally saw mango's post and the FCP Euro kit which I was set on getting on but I recently came across the ECS Tuning ones and I'm wondering if difference...

My ownership of my 2001 325i has been great, it's probably the most fun I have ever had with a car, and it has turned me into a car/BMW guy. However, there has been a glaring issue with the car since I purchased it back in October of 2018. Coolant is leaking from somewhere and after 2 mechanics...

Hello, :hi: I'm having a very strange problem with my E46 328i(M52TU). Some might say it's a head gasket, others will say its a cracked cylinder head or block. :argue: The problem occurred before 4 months. When i start up the car it miss fired very badly for 15-20 seconds. After that the car...

Hey guys, I had recently purchased a 2003 325xi (Manual), a little over a month ago. Everything up to last week had been perfectly fine until I was sitting in some pretty bad stop/go traffic and looked down to see the temperature gauge rising rapidly. I immediately pulled over and shut the...

Its a sad day for fanatics everywhere.. Earlier this week my sister's 323 suffered a catastrophic cooling system failure. Was not given any details as to what exactly went wrong however we have been told it will not start and will need a new engine.. This is exactly why we turn our cars off...

So, I just replaced my oil filter housing gasket. I didn't notice anything out of the ordinary, like coolant leaks or other oil drips. All the cooling system parts were in good shape. I did replace the water pump/alternator etc. belt, which was cracked. Soon after that, I started hearing a...

I started my car (2005 325i) earlier today and the low coolant light flashed yellow on the dashboard. I shut the car off and turned it back on and the light disappeared. Fearing that it would overheat and leave me stranded if I drove it to work, I refused to drive the car until I had the issue...

Just bought a 2004 330xi with 150,000 miles. From what I've read on this site and others, it's clear that the cooling system needs to be overhauled at least once over the life of the vehicle. Is there any way to tell if it's been done recently? The vehicle has been well maintained by the...

OK, so I just got a price from the stealer for a cooling system leak. The tech states that the system is leaking from multiple places; he wants to replace basically the entire system, with the exception of the radiator itself. The price is $1278 +tax. 3 1/2 hours labor for $553 and the rest is...

I have a 2011 328i xDrive with 125,000 miles. Last week a squealing began when the engine was hot and at idle. The squeal subsides with increased RPMs and disappears around 2500 RPMs. Also the engine seems to idle a bit lower and rougher than previously. It's idling about 500-600 RPMs vs. the...

Hello everyone! Now as you can see by the title, I'm looking for a good site to buy parts from. I'm actually looking for a cooling system overhaul kit for my 325ci. I've been looking for quite a while and always resorted to purchasing parts from a shop called Jarry Auto Parts here in Montreal...

This question seems to come up daily, so I made what I hope is a simple, easy to follow DIY. https://gumptiontrap.wordpress.com/2016/11/30/bmw-how-to-bleed-the-cooling-system/

Hope my video helps with getting out your stuck bleeder screw and save you money by just buying the screw and not the whole upper radiator hose. (80$) DONT BUY AFTER MARKET PLASTIC SCREWS! Only OEM, around 6$. https://youtu.be/4p0tep4D6kg
