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...

pressing the 19 time and then the 7 times is tedious is there any way to make the display show the coolant temp constantly at every start?

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...

Hello! I need some help with a cooling issue I have. I looked around the different forums and haven’t came up with my exact issue yet. 2004 100,700 miles. Original cooling system. I noticed my coolant temperature gauge dropping slightly when I am coasting on the highway or stopping at a light...

On Friday my 330ci started running a little over the middle of the gauge, I took it to my shop because I know about the coolant temp buffer but they said it seemed fine. I used the test function on the dash to get a more precise temp and it seems to run between 89 and 98-99 Celsius, from a hot...

Hello first post here because I'm tierd of this problem. I have changed the thermostat, water pump, lower temperature sensor and aired the system to the best of my ability. No milky oil either. My problems is that at idle and stand still the temp gauge goes to dead center but no heat into the...

Just received my Graf water pump in the mail, the sheet metal impeller hasn't really impressed me but a few of you guys seem to swear by them. What's the take on them in 2022, is it a vocal minority? Just go with the OE Saleri pump instead?

Hi everyone, At the start of this year I bought a manual 160,000 mile 320ci and I haven't any information regarding maintenance of the cooling system I'm going to act as if it's all original. Because I intend to hold on to this car I want to follow the prevailing wisdom across this form and...

Just swapped in an electric fan on my manual swapped 328ci, but cant seem to get the new fan to come on. Even when manually activating the fan in INPA nothing seems to happen. I swapped back in the old push fan in the front, and that seems to work both with the engine running, and through INPA...

So I bought another touring, this time I wanted one with a better pedigree, so I found one in Oxford Green, tan interior. The touring was actually very well-maintained by qualified mechanics through its life (2 prior owners). I have all the records including original sale. The transmission had...

When I bought my car 3 years ago, it had red coolant. No idea why. Since then ive had literally ALL the common cooling system problems, including a blown head gasket. I have since fixed/had everthing fixed but kept the red coolant because I coulnt be bothered to fluch the system and replace it...

I’m planning to replace my expansion tank ,I’ve heard that when you replace the expansion you have to replace the thermostat at the bottom also because it breaks, Is there a way so that it won’t break or is it inevitable?

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...

For all my e46 techs any opinions or responses would be greatly appreciated as im completely lost rn. Heres the back story. Thank you in advance for taking the time to read this The winter months of canada - Recently ive noticed that my cars heat from inside the cabin has been blowing cold...

So I'm planning on doing a whole cooling system overhaul, and I believe from previous experiences and research that automatic transmission cooling systems are different to manual systems. Another issue is that my car has been manual swapped by the previous owner (smg gearbox). Is there anything...

I haven't said too much about it but I wanna share the experiences I've had with owning this car for a little bit. It's an Australian 2004 320i E46 touring. So far I've ordered some new cosmetic parts such as floor mats and new grille and badge and I have also ordered a new expansion tank...

Another thread about the hard coolant pipes under intake. While removing the broken ends of the hard coolant pipes, a plastic piece fell off of the heater inlet pipe and into the cylinder head water jacket. While trying to remove the piece with long tweezers, I have pushed it farther in and it...

Recently, I picked up the 5MT 330i sedan while knowing it needed some work on the fan/fan control. I was told it was only the ignition needing replaced as the fan wasn’t shutting off. On the drive home the fan control module (the little silver box?) was smoking. We unplugged it and got home...

Hello, I wanted to ask if theirs a way to monitor my engine coolant temps on my phone or a screen while driving. Im looking for something that would preferably plug into my obd2 and give me accurate engine temps with numbers instead of a gauge. I want to monitor these temps because I’m looking...

‘05 M3 with ~146k miles, stock cooling system. It was about 75-80° today while I was going up a tight switch back mountain road. Stayed above 4k rpm for about 15 minutes straight, and about 12-13 minutes in the water temp got to just below 3/4ths, oil temp was dead center maybe a hair above...
