03 bmw 330xi won't start after replacing radiator HELP!
Earlier this week my 330xi overheated and a crack
was found in the radiator, so radiator was replaced
however still wouldn't start. A fuel pump was
suggested to be the problem so replaced fuel
pump also, all fuel pressure checks out perfectly,
but car still won't start, it will crank but not fire. I
noticed the oil light is red, and a new light is on it's
a triangle with an exclamation point, never had it
come on before. The battery was put on a slow
charge after it depleted during starting attempts.
I've been reading some forums on the red oil light
and see that this is a common issue, but with the
overheating and radiator replacement I'm worried it
could be something else. I did bleed the lines as
advised (heat on 90 degrees, low fan, etc). I'm at a
loss as to where to check next!!!
Good on the correct bleeding procedure! Red oil light means you have an oil pressure problem. How is the oil level? Might be the oil pressure switch. When the car overheated did you stop the car immediately or continued to drive? If you did, could be something serious. If it cranks, it's either fuel pressure (which you checked) or spark. Did coolant get on the electronics under the engine bay? The alternator is close to the radiator. Did you recheck all your connections? BTW: The triangle light is part of the DSC or traction control, so probably not the issue. Did you scan for any fault codes?
Borrowing a scanner today. I stopped the car within minutes of the overheating beginning, but antifreeze was all over tge
Disregard my premature sending.... to continue antifreeze did get on the engine. The alternator is less than 2 months old, but haven't checked all connections yet. About to dive in again today. Oil level is good, no milky or red appearance to it. Thank you so much for the input!!! Love my car but she's temperamental haha.
