trouble with a 525e (e28)
its overheating too quick. dont know why ive changed the oil, and it had no coolant in it. good sign. i replaced the radiator fluid and bled the air from it. cleaned the thermo sensors on the radiator itself. the fan to cool the engine isnt kicking over to cool. so my theory is the thermostat.. am i right or could there be another issue. because its still over heating.
