    Hello for some context I drive a 04 325xi, I've done the coolant over hall and have new parts for everything coolant related except for the radiator. Also note that I live in Colorado and it has been bellow 32f for the last couple weeks. A issue I've been trying to resolve for some time is my...

    Hi all, I recently just done a coolant flush, but I found there's a weird situation that my coolant light would be on only when I drive on highway, and off when I drive off. No coolant light when I drive in city/below 60 mph. I'm positive that I bled the cooling system correctly, according to...

    Hi all, I have a 2003 325i e46 M54. I heard the normal operating coolant temp should be 94-96C but when I drive on highway at 65 mph most of the time it stays at 90C (194F) exactly and sometimes even dips to 89C (192F). Is this normal? Just recently done a coolant flush with Valvoline Zerex G48...

    Hi there, first post. I just checked the coolant in my 2002 330i for the first time in a long time. It seems to be low/empty. I haven't had any cooling lights on the dash or any overheating problems. Any suggestions? Am I good to pour in new coolant?

    Hi all, I have recently encountered an issue where I find myself having to top off the coolant in my vehicle more frequently than before. Today, the situation escalated as I discovered a noticeable patch of coolant on the garage floor. Initially, I assumed it would be a straightforward fix...

    Hi, here’s hoping one of you will confidently diagnose my issue and that it’s an easy fix! I have a 318i manual, petrol, year 2000 e46 Yesterday I drove 150 miles, it was very cold outside so I had the heating on. After 50 miles the temp gauge was reading v hot. I pulled over - the coolant was...

    Hello hello everyone! Riddle me this: On my N42B20 engine, when I disconnect the valvetronic module - it runs at a constant 103-105 Celcius (217-221 F). Buuuuut, when valvetronic is plugged in and working - it fluctuates between 85-105 C (185-221 F). Heats up to 105 -> drops down to 85 -> then...

    Hey guys, Yesterday afternoon, I was driving from downtown San Jose (60m/197ft) to Lick Observatory (1271m/4170ft) while the ambient temperature was around 33C/91F. I was a bit concerned about my E46, which is a 20-year-old car, it can go overheating while going uphill. To ease my worries, I...

    So I’m taking off my intake manifold to change my main engine coolant sensor, and I encountered a weird ripped off vacuum hose, that comes from the intake manifold itself. It’s an M56, so not the typical M54, so I can’t find anything on this POS. Could anyone tell me what this vacuum hose and...

    Hi everyone, I have a question regarding my overheating problem, my e46 has a problem in a hose that connects the coolant container to the engine. I’m not sure the name of this hose. The issue is a leak. I need to replace it. However, I’ve been using regular water to drive around 14 milles...

    So I just replaced my thermostat because the code P1620 was coming up, I figured that I should take it apart and see if it is my thermostat, however I just changed it, replaced my coolant, but my temperature gauge keeps fluctuating like this. When I used to drive it before I finally changed the...

    Hey, so I bought this car not too long ago and I have been monitoring my oil and coolant levels. First thing since I bought the car was a ccv change, oil change etc. Sometimes when I'm reversing there is a lot of white smoke coming from the exhaust, but only when I'm in reverse. Today I had to...

    Hi, I seem to be having an overheating issue with my car. In traffic the temperature creeps up to 120 degrees Celcius.. So far I have replaced the thermostat, flushed and bled the coolant. I can't figure out what the issue could be as it doesn't happen all the time. My car has enough coolant...

    Hello everyone. I'm new in this forum and I have a problem with my car. I drive a 2003 320d Touring with 6 Speed manual transmission. When I go with 3000rpm or higher coolant level light cames on and it stays on until engine rev gets below 3000rpm. Coolant level is fine and bled the system with...

    I bought an e46 about a month and a half ago (02 330ci) and it had its fair share of problems i was willing to fix, I bought a whole plethora of stuff to refresh the engine and make it reliable (as it can be for an m54) I bought an oil pan gasket, valve cover gasket (vac leak that i have found...
