    Recently, I picked up the 5MT 330i sedan while knowing it needed some work on the fan/fan control. I was told it was only the ignition needing replaced as the fan wasn’t shutting off. On the drive home the fan control module (the little silver box?) was smoking. We unplugged it and got home...

    Hello, I wanted to ask if theirs a way to monitor my engine coolant temps on my phone or a screen while driving. Im looking for something that would preferably plug into my obd2 and give me accurate engine temps with numbers instead of a gauge. I want to monitor these temps because I’m looking...

    ‘05 M3 with ~146k miles, stock cooling system. It was about 75-80° today while I was going up a tight switch back mountain road. Stayed above 4k rpm for about 15 minutes straight, and about 12-13 minutes in the water temp got to just below 3/4ths, oil temp was dead center maybe a hair above...

    Hi guys! I just wanted to show you my car. I joined this forum in autumn 2020 when I bought my first BMW. It´s an E46 323i sedan made in June,2000.

    2005 325i 5 speed Was driving on the highway and noticed my temperature was all the way in the red, pulled over and looked under the hood to find no leaks or cracked reservoirs. After waiting about 10 minutes I attempted to start the car, it took a noticeably longer time to start (not very...

    Hell! I'm fairly new to owning an E46, having just gotten it October of 2020. I've been slowly working on a drift build process and currently I am wondering if anyone knows where I could find a simple oil cooler for it? I was looking to see if there was any oil filter sandwich plate setups (if...

    Hi folks, new user here, I've had a 2004 e46 automatic for about a year now, first car, & I've been chasing cooling leaks n issues ever since :). Skip to bottom if you want to go straight to my question. But here's context: I did a cooling system overhaul when my temp sensor got stuck open...

    I have an '03 330i, and I've bled the cooling system a few times now. Either I'm an idiot, or there's a leak somewhere in the system. I want to rule out any leaks, because I don't see any coolant on the ground and the coolant light doesn't come on. The cooling system is the only trouble I've...

    I burped my car yesterday and during the process of that it didn’t overheat but I’m not sure where the water and coolant went bc it would be full when I start burping but by the end there would be nothing in the reservoir, can someone help me, I replaced my thermostat, radiator, ac thermostat...

    One day, about an hour away from home my fan blade exploded and cut my transmission cooler up so I acquired a new one. While uninstalling the line from the cooler I broke the quick connect fitting so I thought I could just throw some hoses over each end and clamp it and be fine. I was wrong. So...

    I currently own a 2002 325xi with 182,000 miles that is running very well (lots of work and PM since I bought it 5 years and 50,000 mi ago. I have done most of the work myself. I am currently looking (for a second car) at a 2004 325i at a dealer who is selling it as an "as is" wholesale sale...

    Hi there, Been having some issues with coolant slowly disappearing from my e46...replaced the thermometer housing recently, after a whole cooling system replacement ~2 years ago (water pump, impeller, etc). I've replaced the rad cap in case that had any effect, but I'm wondering if replacing...

    My 328i just started to overheat in this summer heat and we cannot seem to find any problems with the cooling system ALTHOUGH there is no auxiliary fan sensor box mounted on the shroud and I can't remember if there ever was one. Can't even find a cable to run to the box either if there was one...

    Hey guys, Does our forum have a sponsor that can help give a discount on an electric water pump? I"m afraid mine is starting to fail. Or can someone point me to where I can get a reasonably priced one? Need one asap. Thanks!

    Hey guys, I was wondering if a 2002 316i has a clutch fan or an electric fan? If it's a clutch fan, is it hard to switch to a temperature operated electric fan? And how would one do this? Any help is appreciated since I couldn't find any info while googling for it. Thanks in advance.

    So last night after I raced my friend I looked on my dashboard and my engine was over heating! I pull over and there is like a storm of steam coming out near the coolant tank. We let it sit for a while to let it cool down and there was this boiling sound we heard also. I was trying to get it...
