NEW, never used, air filter, power steering belt and windshield washer pump (rear). If you own a GM 5.3 ... you will need these some day!
All still in original packaging with receipt. They cost me $61 plus tax and shipping. The price has gone up since I bought them! Only $20 firm for all.
Universal serpantine belt installation tool, NEW, never used, available also. This takes the tension off the belt, so you can replace the serpantine belt easily! Only $5 ... but in addition to the above maintenance parts.
