Toyota 17120-0S020 Manifold Assembly, INTAK

Check the condition of the upper intake manifold gasket and replace it if necessary.

1. Remove all traces of old gasket from the intake manifolds and clean the mating surfaces with brake system cleaner. 2. Install new gaskets into the grooves on the manifold. Position the 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 the remaining parts in the reverse order of removal. 5. Refill the cooling system. Run the engine and check for fuel, vacuum, and coolant leaks around the throttle body hoses.
