    Please drop me a sentence or 2 if your tank & sensor are OEM .. but your "low tank" light pops on inappropriately. Our 2003-4 coupe & sedan both do that. Yellow dash light turns unexpectedly when the engine when temp, level are fine. If you do experience that does it typically happen when you...

    Okay as part of my cooling system overhaul, i'm wondering if the Mishimoto Performance Aluminium Radiator Non-M (MMRAD-E46-323A) is worth it. I'm all for performance mods and I have already gotten their CAI kit installed. Although, i'm not sure if it is truly worth the money compared to the...

    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...

    I'm installing a new radiator today and when I get this plastic piece that supports the expansion tank on, this hole is still wide open causing coolant to leak out when everything's installed and im filling it back up. There was no plug on the old radiator, nothing that came with this radiator...

    It's weird. Im just going to spill what was done and things that appear wrong for me. Everything started with leaks and I figured maybe engine is overheating and has too much pressure in the cooling system. When engine is warm upper hose is stiff and hot, lower hose is cold. INPA readings are...

    Hi, I was driving in my 2003 325i automatic when I noticed it was overheating, I stopped got out of the car and my coolant expansion tank blew up. I guessed I was low on coolant so it overheated. The next day I replaced it, filled it up, bled it, but I wasn't getting warm air from the air vents...

    As always thanks for the expert insight and guidance .. I'm the original owner of this noted 2002 325ci. Only 31k miles. I ordered it back then with the available "Sport Package" option. For the lifespan of the car I've lived in a high-rise with an outdoor lot that is located about 200ft from...

    Hello, I've got a 01 330xi (M54) that is running hot. I have an OBDII Scanner and OBD Fusion application. I just installed a brand new radiator and Upper and Lower hoses (Gates) and have probably used 10 gallons of antifreeze trying to keep it cooled down enough so I don't ruin the engine...

    Hi again, Sorry for the weird title. Please see the attached pictures to know what I am talking about (FYI, the fasteners and hoses are on the drivers side of the expansion tank). The white plastic fasteners seen on the pictures (Red circles) were dangling around loosely. On the pictures I...

    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...

    Coolant level question for new-to-me 323ci Hey guys, just got my first E46 and am totally stoked about it. It’s a beautiful 2000 323ci w/ 176k miles. I recently checked the coolant level and the red float stick was all the way down (not floating at all/won’t move if you push down on it...

    Pretty new to the E46 game. I have a 2004 325ci convertible. As I was driving back home today, I see white smoke from the hood, and smell as sweet burning smell, and the engine was overheating. So I pulled over and saw that the coolant was boiling. After I let the car cool down, I see that I was...

    Hey all, I was doing a bunch of maintenance and doing a cooling system overhaul. I was removing my radiator and realized the Torx screw was missing from the top passenger side mounting point on the top of the radiator. Does anyone know what size I can use? I searched and looked through OEM...
