15-22 ft lbs, then you also have to retorque them after the engine is warm. By the way, there is a specific sequence to follow when tightening these bolts - see below...Imagine this is an overhead shot, with the front of engine at the bottom of the graphic (like you would see the engine while standing in front of the car with the hood opened). Tighten them in this order:
8..........7
4..........3
2..........1
6..........5
9.....10.11
Bolt #10 is on the left side of the thermostat housing.
Best of luck and Welcome to StangNet!!!
