    So today I did my check up on my car usually checking the oil, coolant level, ect. But what I noticed today is two problems, I’ll start with the first. So a common issue it seems like I’ve noticed is the radiator outlet coolant temperature sensor leaking with these cars. I had an extra oem temp...

    I recently have come across a coolant leak on my 2003 e46 325i. It only leaks once it’s built pressure. After taking a look from underneath the coolant is quite literally everywhere. And the highest point of the leak is on the upper radiator hose. I replaced the hose, still the same issue, I...

    Hey guys, lately I’ve been gathering all the supplies to do a full cooling system overhaul as I feel it would be a good time to do it because I have the car stored away. I got everything put together and all went well until I went to fill my coolant back up and noticed a small drip from the...

    Ive been having this issue for months now, i like to do my own work on my car but this one stumps me. I can fill my radiator completely full, drive it for a couple of hours, then the next day ill start it up and its low and the radiator light is on. Ive looked under the car, no leaks. Ive...

    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...

    I recently diagnosed my e46 and found a leak coming from under the intake manifold and it’s leaking on the block. I have a video and some pictures. Not sure if the block is cracked or the heater inlet pipe is leaking. When I apply my pressure tester to the cooling system I can really tell if...

    I’ve been working on my new but recently old bought 2000 323i, I replaced all old coolant hoses and yet still have a mystery leak. The leak is not bad but is draining my coolant. The leak is coming from someone near the expansion tank. Components such as the expansion tank/ bracket are new as...

    I realized a little earlier today that my car was running hot and when I had a chance to take a look at what was happening I discovered that there was a coolant leak. Since I know I'm going to have to flush out the radiator anyways with any repair to the coolant system I used water to help me...

    2004 BMW 330ci So couple of days back, the radiator sign popped up in the dashboard and since I was driving along the highway and didn't have any extra coolant on me, I bit the bullet and kept heading home to take a further look( i know, big mistake). I was almost home when the temp gauge went...

    My engine fan would come in after 20 minutes or so of driving. Sounds like a damn semi truck! Engine Temp gauge on dash never went above normal unless I was taking a long drive (2hrs or so) The fan in front of the radiator (bumper side) never comes on. Ever. Sometimes my AC works, mostly while...

    So a while ago i blew a belt on the freeway very close to my house (3 blocks away) so i coasted home with no power steering and a quickly overheating motor. Anyways i made it back and changed the belts. I noticed that after driving for a bit, tons of steam and coolant poured from under the...

    Ok, ladies and gents, I have an issue and would like your opinion. The wife's 330CIc with 200K on it is having some coolant issues. Also it is running roughly at idle and especially at cold start up. Had some smoking issues but I quit cause I hear it is bad for you. The car did too, it is a...

    So I recently replaced the expansion tank and its mounting plate. Everything worked fine for a day, but I checked my car the next morning and there was a low coolant issue. I opened up the cap and there was an audible hiss so I think the pressure in the system is fine. But I'm no expert. I...

    I've been scouring this forum and web to be a bit better prepared for whatever the bad news is once I get to my mech. However, I can't seem to find what I'd consider a solid estimation of my issue. In short - coolant leak. Just started seemingly out of the blue. It does not appear to be coming...

    Hey I always am runnin into bullshit mechanics that try to jerk me off just because I'm a chick but little do they know I have some auto mechanic experience but now here are my questions.... 1.Do I really ALWAYS need to go to BMW to buy parts? 2. My coolant keeps leaking and every other day...

    I've got a 2001 325i (e46 of course!). It's leaking coolant. I started the car today, watched, nothing happening. Let it run for 15 minutes or so, checking every so often, and on the last check, there was a puddle forming under the car. I hunted around with a torch, and could see drips, they...
