18. Attach the pump to the timing chain housing nuts and the coolant inlet cylinder to the include. Further tighten these by ability.
19. Torque all bolts to the consequent specifications after all bolts corner been inserted and share tightened: the chain housing nuts to the pump meeting to 19 foot pounds (26 Nm), the water pump assembly to the cover to 124 foot pounds (14 Nm), and the water pump cover to the coolant inlet pipe assembly to 124 foot pounds (14 Nm).
20. Reattach the cylinder head and the exhaust manifold, tightening the nuts to 11 foot pounds (15 Nm), the coolant inlet pipe to the oil pan, tightening the nuts to 19 foot pounds (25 Nm), and reattach the timing chain tensioner, tightening the bolts to 89 foot pounds (10 Nm).
21. Reconnect the camshaft housing and the brake vacuum pipe and reattach the front cover, tightening the bolts to 106 foot pounds (12 Nm).
22. Reattach the exhaust pipe and the manifold, tightening the bolts to 26 foot pounds (35 Nm), the exhaust manifold to the brace, tightening the bolts to 41 foot pounds (56 Nm) and the nuts to 19 foot pounds (26 Nm), the manifold to the exhaust pipe, tightening the nuts to 26 foot pounds (35 Nm), the heater pipe to the heater hose and reattach the exhaust manifold heat shield, tightening the bolts to 124 inch pounds (14 Nm).
23. Reconnect the electrical connector to the oxygen sensor and the negative battery cable. Refill the engine's cooling system with coolant and start the car. Check for leaks when the engine reaches normal operating temperature.
3.1L and 3.4L Grand Am Engines
