So I was driving on the freeway and randomly the coolant light came on, I pulled over and checked the level and it was full. I got back on the freeway and the light came off, the car didn’t over heat or anything. Could it be because it’s extremely hot today or something serious?

Hey y’all, I’m new to the forum and havent found any issues like mine exactly. My engine recently almost blew. the wife stretched her 13 miles overheating. Thankfully the engine survived. The serpentine belt snapped off the pulley and mixed up the fan badly. Needless to say, my alternator belt...

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 guys So i just did a clutch fan delete and also a mishimoto fan controll for the cluster fan because I just finished a head gasket job and complete cooling overhaul. Now with the fan turning on at 90 degrees temp, Full Power! my temperature still goes up to 97 with the heater on and when i...

Hey, so I've got yet another problem with my car. Recently the car started overheating. Changed the water pump since it was leaking just a bit and also got a new thermostat, since the shop told me that the old one was blocked. After that the car continued to overheat. What I did found out is...

I have a 2003 325i. I have replaced the overflow tank due to it bursting, the water pipe hose, the radiator, the water pump, water pump pully, fan clutch and fan blade. Somehow my system is still getting hot despite my being sure that each new part would solve the problem... what next...

Hi there, Was driving home from work a few days ago and got stuck in some standstill traffic. Was not really paying much attention, until I looked up and noticed my temp guage was lit up (yes, I didn't notice until the light was on). I immediately turned off my car but didn't have a place to...

Hi all, I've done plenty of searching, but I've failed to find someone with the exact same situation as me. Basically, one day, shortly after a cooling system rebuild, the car was unusually hard to start. It took two tries to get it to fire up. I thought nothing of it and proceeded. Later...

Hi guys, This is a 2004 325ci automatic. Just for background information, the car overheated, but I shut it off and let cool. So I searched around and found a Crack in radiator pipe that was blowing coolant out, so I changed the radiator. I bled the system using mango's method. However, when I...

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 everybody. So I have a 2000 323i automatic that just won't behave. A couple of days ago I was driving home and overheated. A surprise since last summer I replaced the expansion tank, radiator, and hoses. Got the car towed home refilled with coolant and she held everything without spilling a...

Okay I'll present what's become a tricky issue for me. I'm sure you smart folks here can assist. I've looked through the boards here and it's really impressive to see the expertise here. My coolant expansion tank blew the other day so I replaced it, the lower thermostat, and the water pump (it...

My wifes 2006 bmw 330 ci is overheating very quickly when it is driven. I can go about 2 or 3 miles to red line hot. It will go from cold to center (normal) in the first mile. Then stay on normal for a mile, then go up to the red zone in a matter of seconds. I may go from mile 2.5 to 2.7 and it...

Hey guys soo with all the coolant problems on e46s and the dummy temp gauges that bmws have, i was wondering how to install an aftermarket precise temperature gauge. Dont wanna play the waiting game untill it overheats, i wanna be able to check coolant temperature easily, And i was wondering if...

Hello everyone, recently my 330i has started to overheat and I'm not sure why. I have replaced thermostat, radiator, expansion tank and the entire cooling system upfront as far as that goes. As well as fans. My bmw mechanic thinks it may be the lower coolant pipe that is leaking but they are not...
