    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...

    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...

    Recently I had to replace a belt tensioner, belt tensioner pulley, and two belts on my 99 323i. After we replaced these, I drove it about two miles in a residential neighborhood with no issues. When I left my friends where we fixed it and got on the interstate it began overheating after a mile...

    Ok. So it finally warmed up enough in the Chicagoland area to start looking at where I might be leaking coolant from. 20 degrees. With hands freezing and air box/filter removed, I came across this. I cannot see anywhere else where there is coolant leakage. Expansion tank replacement needed? The...

    I recently got a new radiator, water pump and thermostat for my E46 BMW 325i. Prior to bringing the car to the mechanic I also had a SES light on my dash and the car was not starting on the first key turn (not sure if they are related). Anyway, drove the car home and the next day my radiator...
