Toyota 17120-0S012 Manifold Assembly, INTAK

1. Remove all traces of old gasket material and sealant from the upper and lower intake manifolds and cylinder heads, then clean the mating surfaces with brake system cleaner. 2. Install new gaskets. Position the lower intake manifold on the engine and install the fasteners. 3. Tighten the fasteners in three or four equal steps to the specific torque, working from the center outwards to avoid warping. 4. Install a new gasket and the upper intake manifold onto the lower intake manifold. Install the nuts and bolts and tighten them in three or four equal steps to the specific torque. 5. Install the remaining parts in the reverse order of removal. 6. Check the coolant level. Run the engine and check for fuel, vacuum, and coolant leaks around the throttle body hoses.

Remove the two intake manifold mounting nuts and four mounting bolts, then remove the upper intake manifold.
