Vibration noise from engine
Haven't had my car out in a few weeks. I started it today and noticed a vibration sound from under the hood. I inspected under the hood. and it seems to be near the front and towards the top. I manually inspected the pulleys and none felt loose. I listened again and it seems to be the damper for the coolant pump pulley. I checked this and it did seem to have some play in it. Is it ok to tighten the four bolts on this? Or is this because of a bigger issue. Also will I do any damage if I drive the car with this being loose? Hopefully that makes sense. I am new to doing more than just driving a car. Any suggestions would be appreciated.
