    Hello, I have a 2000 316i that has a coolant leak from the top of the expansion tank. It was replaced a while ago and ran fine for a while. Now I have the same leak as before. It only leaks after I shut the car off and let it sit overnight. However it sometimes leaks enough to trip the coolant...

    Afternoon guys, I’m already aware of a coolant leak on my 320ci Cabrio - I don’t know where it is but I know it’s there. However my coolant light is staying in after about 3 minutes on every drive. My engine temp doesn’t move from the 12 o clock mark at all either. After checking my coolant...

    Hi everyone, Next month I will be moving from Boston, MA to Raleigh, NC and will be driving my 2005 325i for the 700ish mile / 11 hour trip. I was hoping to get some advice on any general preparations I should do for the car. I plan to get an oil change in the next week or so. In the last two...

    I am looking at a friend's 2003 325i (Oct 2002 build date) with 170k miles that has been losing coolant without any external leak and also suffering from intermittent cold start misfires (INPA codes 239, 240, 241, 242, 243; and P1347/P1349 type codes on obdfusion). This car was overheated after...

    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...

    First off, I have SCOURED Google and these forums for an answer, so sorry in advance if I missed it. Anyways, I have a 2000 323i and long story short, it overheated due to the idler pulley breaking, so now I'm replacing the expansion tank. When I went to pull out the old atf thermostat...

    Is there a kit for the manual trans version of the e46, or will the ones stating "for automatic transmission" still work? Looking for one that has the mount with it as well. When it popped, it took some of the radiator plastic and possibly parts of the mount with it. Thanks!

    So I currently have an issue whereby Iv broken the expansion tank mount where the ET top hangar is meant to hang on to. Could this be the reason why I can't seem to get the Expansion tank to seat no matter how hard I push down ?

    First of all, I know there are many posts under " head gasket" but this is my first post and I still had to ask before spending big bucks. A little background,(and the biggest regret of my car ownership life) I had to drive my car after the expansion tank cracked, all the coolant was leaking...

    Hey all, New to the forum here. I recently took ownership of my brother's hand-me-down, a 1999 BMW 323i (E46). While I was changing out the expansion tank, I noticed a pretty significant hole in a hose which is adjacent to the belt running between the alternator and power steering pump. The...

    So I just got the P1624 SES on my 2000 e46. I know this is computer/ engine specific, so I have a 2000 328i M52tub28 engine 5 speed auto/sport :thumbdwn: I believe the date of MFG is around march of 99. I've heard it could be the thermostat with my model and year. I replaced the upper/lower...

    Hi Guys, Looking to do my cooling system and have found some cool products online! Mishimoto do an aluminium expansion tank that I would love to get my hands on or something similar. I have also seen some thermostats that let the system run cooler. Does anyone know of any local shops that sell...

    2002 325i Just got this car. Coolant was low in the expansion tank. I filled it up, ran the car with heater. Filled it up again. When I stopped the second time, there was coolant steaming/spitting out of the top of the connection where the upper radiator hose connects to the radiator and the...

    Hello all! I purchased my 2000 BMW 323i about a month ago. It currently has 134k miles. About five days ago I made a two hour drive to Tampa, FL and all seemed to be alright. I had the A/C on the entire time being that it was at least 90 degrees. When I was a few miles from my destination, I...
