hydraulic cooling fan pump vibrating
my 93 sc400 is running a little hot driving down the road. when i say a little i mean its almost in the red. i grabbed the pressure line that goes from the hydraulic cooling fan pump to the fan and it was vibrating like a bearing is bad. is this normal for our cars or is it supposed to be smooth. If its supposed to be smooth with no vibration in the line then that is most likely the reason for the overheating. its all the same from 93- 97

ya the fluid level is fine and the fan turns free its just when under full pressure i feel a hardcore vibration in the pressure line. and yes it speeds up with engine speed
