is having one washer nozzle make a difference when it comes to spraying on your windshield?
Has anyone else experienced pulley squealing sound?

 

Not really and no

 

The single nozzle works fine in my opinion. The squealing I heard turned out to be a bad water pump. I guess there is a water pump issue with 2012 & 2013 jeeps.

 

2012 JKU here with AEV hood & 10,000 miles .... no problems reported ...

 

If you develop a slight whining, chirping, squealing noise make sure you check your coolant level in your overflow reservoir. That will be a sure tell tale sign you have a water pump starting to go.

Mine was a 2013. I had to wait over a week to get the Jeep back because the water pumps were all on backorder status. Basically telling me that a lot of Jeeps in the 12 and 13 model years have defective water pumps.
