2012 nissan sentra
I got the battery and brake light came on while driving on the freeway. I thought the alternator went out, made it home, them learned that serpentine belt was broken. Inspected the tensior pully, I am noticed the gap is slightly larger than normal, also dont fully understand the arrow mark.
Question 1 : is the triangle arrow need to be directly in front of the square notch mark, therefore the existing pully is bad, and need to be changed? The pully does spin freely, no wobble when move it side to side. Should I change the tensioner pully or just install a new belt?
Question 2: noticed alot of leak around the crank pully. Is that coming from the shaft seal and is unrelated to the belt issue? Thank you in advance! Picture are on the link below.
Bro, you probably need a new crankshaft pulley seal and leaking oil. Can of course make the old belt go off. I would replace the seal in the belt and then see what happens. Tensioner seems okay
@scottykilmer thank you for the feedback!
