Diagnosis help
seems like I've got a squeaky pully bearing. It sounds like its coming from the crank pully, and when I spray some WD40 back behind the pully the squeaking stops.
However, I also have a coolant leak someplace that I cannot locate, I just smell the coolant but not very strong and there is no visible signs of a leak anyplace.
Do you guys think I have to replace the crank pully, or maybe its just a leak from the water pump leaking down onto the crank pully?
just want some opinions before I start tearing open the front of my engine.
thanks in advance.

There's no bearing on the crank pulley.
It's probably the water pump. They are easy to get to though so you won't waste too much time if you pull it off to inspect it. Just get new gaskets first.

you can try tightening the water pump bolts just a bit or get new gaskets and that might fix it but they are common to leak behind the pulley on the water pump and the coolant will get on your belt and cause a squeel which is what it sounds like is happening to me... check the top side of your front spring, the leaking coolant likes to puddle there so you may not see it hitting the ground
