So I put on my motor mounts back in and I started my card last night and me and my roommate realize that the serpentine belt was grinding really bad so I don't know if I needed to lift my engine again and loosen the motor mounts and lift my engine more before I mount it but right now I have it up in the air I have a jack on my passenger side underneath one of the jack spots and then I have my engine lifted with another floor jack I need some guidance here please

 

How many did you replace? Two or all three? The top and bottom on the passenger side just reduce rotation. The one in the middle is what mostly supports the engine. Did you replace that one? What is your belt grinding against? The 2.4 belt has a fairly simple routing. You did route it right didn't you?
