I have a 92 e36 325i that keeps ovheating. I've replaced the radiator, fan, and water pump and it still overheats. What could be the problem? Could it be as severe as a rebuild. I'm gonna try to flush the system a few times today to see if it helps.
thermostat (a $10 part)
or blown head gasket

I forgot to mention I also did thermostat.

Could be cracked block or head, rebuild won't fix.
Verify you have the proper oil levels

Proper fluid levels and everything. Side note
I took the cap off and turned the car on and bubbles started coming up. Not a lot tho. I've heard that signifies a headgasket? Could you guys let me know? If flushing it doesn't work I'm just gonna tear it down and replace the gasket

Yes, that's the head gasket.

quora says head gasket. I'm sorry for your loss

could be a lot of air trapped in the system if you replaced a lot of components. Its definitely overheating? or is that just what the factory gauge says? And did you put the thermostat in facing the right direction? I would think if were a head gasket than there would be more obvious symptoms than overheating

Car def overheats. Overheated 2 times in 5 blocks yesterday trying to diagnose.
