Hello Everyone Just a quick question about the New idler pulley and new belt i installed about 3 weeks ago.. Car runs perfect no belt noises just perfect--I did however notice the New idler pulley has a line on it that goes around the complete pulley--The pulley is smooth but if you take your finger nail across that line you can feel it.. Pulley did not have that line when installed and New Gates belt looks perfect... Any ideas.. PICTURE ATTACHED Thanks and have an awesome day!
