I have a 2004 bmw 325i that is leaking a mustard colored fluid from the engine...dunno the source but its obviously something that is mxing possibly oil/coolant or trans fluid/oil or trans/coolant...anyone know? my coolant light comes on whenever i turn on my heat and i get burning smell sometimes outside the car. could this all be related?
Sounds very much like rusty water. Coolant is usually orange or blue and I doubt you would have rust in the windscreen washer bottle. I would check that the radiator or coolant pipes are not leaking/damaged/loose/clamps loose. Might also be corrosion in your heater radiator
mileage is 105k....the car has never overheated on me tho...u had the thermostat replaced 2 yrs ago ....u hope its not the head gasket...its running fine tho
Why not start off by flushing the radiator thoroughly and make a note of what comes out.
You could also have a look in the expansion tank to see what colour the water is. If it matches what you saw dripping out, then there is your problem. I agree with the post about the head gasket, but there should be secondary results like missing, or uneven running. Best to try the easy (and cheap) things first.
Totally agree...
Remove the engine breather pipes too, I bet they're gunked up !!
