Default Turner Pulleys Tight Fit?

Is it normal the water pump pulley is 1mm away from the tensioner. It's so close I'm afraid it may touch it and cause damage.

Mine is the same distance away from the tensioner. It rubbing actually was my first sign that my water pump was going out.

It rubbed and didnt cause any damage? How did you notice? Loud noises?

I've been getting coolant spray on my shroud next to the alternator and a bit on the fan blades. I'm wondering if my water pump is hitting the tensioner causing this leak. I idled it but don't see anything coming out.

It's normal, I just did my Turner pulleys a few days ago and was concerned of the bigger size and clearance to the tensioner. Just make sure to torque down the pulleys properly as a loose water pump pulley will come in contact with the tensioner due to such a small clearance.
