- Remove the engine compartment covers (see «ENGINE COMPARTMENT COVER REPLACEMENT»(/acura/tsx/ii-2008-2014/remont/exteriorinterior-trim/#exterior-trim-v6__engine-compartment-cover-replacement) ).
- Disconnect the MAP sensor connector (A) and the breather pipe (B), then remove the intake air duct (C).
- Disconnect the throttle body connector (A), the EVAP canister purge valve connector (B), the water bypass hoses (C), the EVAP canister hose (D), the brake booster vacuum hose (E), and the vacuum hose (F).
- Disconnect the PCV hose (A) and the IMT actuator connector (B).
- Remove the upper cover mounting bolts and nuts sequentially in three steps, then remove the upper cover.
- Remove the intake manifold mounting bolts and nuts sequentially in three steps, then remove the intake manifold.

- Install the intake manifold. Tighten the mounting bolts and nuts sequentially in three steps. Always use a new intake manifold gasket. Specified Torque 8 x 1.25 mm: 22 N.m (2.2 kgf.m, 16 lbf.ft)
- Install the upper cover. Tighten the mounting bolts and nuts sequentially in three steps. Always use a new gasket. Specified Torque 6 x 1.0 mm: 12 N.m (1.2 kgf.m, 8.7 lbf.ft)
- Connect the PCV hose (A) and the IMT actuator connector (B).
- Connect the throttle body connector (A), the EVAP canister purge valve connector (B), the water bypass hoses (C), the EVAP canister hose (D), the brake booster vacuum hose (E), and the vacuum hose (F).
- Install the intake air duct (A), then connect the breather pipe (B) and the MAP sensor connector (C).
- Clean up any spilled engine coolant.
- After installation, check that all tubes, hoses, and connectors are installed correctly.
- Refill the radiator with engine coolant, and bleed the air from the cooling system (see «COOLANT CHECK»(/acura/tsx/ii-2008-2014/remont/cooling-fan/#engine-cooling-system-v6) ).
- Install the engine compartment covers (see «ENGINE COMPARTMENT COVER REPLACEMENT»(/acura/tsx/ii-2008-2014/remont/exteriorinterior-trim/#exterior-trim-v6__engine-compartment-cover-replacement) ).
Scheme 13
- Relieve the fuel pressure (see «FUEL PRESSURE RELIEVING»(/acura/tsx/ii-2008-2014/remont/fuel-system/#fuel-supply-system-v6__fuel-pressure-relieving) ).
- Remove the intake manifold (see «REMOVAL»(/acura/tsx/ii-2008-2014/remont/exhaust/#intake-manifold-and-exhaust-system-v6) ).
- Remove the injectors (see «INJECTOR REPLACEMENT»(/acura/tsx/ii-2008-2014/remont/testing-diagnostics/#pgm-fi-system-v6) ).
- Remove the harness holder mounting bolt (A) and disconnect the knock sensor connector (B).
- Remove the injector base mounting bolts/nuts (A), then remove the front injector base (B) and the rear injector base (C).
Scheme 14
Scheme 15
Scheme 16
- Install the front injector base (A) and the rear injector base (B) with new gaskets (C), and tighten the injector base mounting bolts/nuts (D) in a crisscross pattern in three steps, beginning with the inner nuts. NOTE: The front injector base gasket is different from the rear one. Do not mix injector base gasket types.
- Connect the knock sensor connector (A), then install the harness holder mounting bolt (B).
- Install the injectors (see «INJECTOR REPLACEMENT»(/acura/tsx/ii-2008-2014/remont/testing-diagnostics/#pgm-fi-system-v6) ).
- Install the intake manifold (see «INSTALLATION»(/acura/tsx/ii-2008-2014/remont/exhaust/#intake-manifold-and-exhaust-system-v6) ).
- Inspect for fuel leaks. Turn the ignition switch to ON (II) (do not operate the starter) so the fuel pump runs for about 2 seconds and pressurizes the fuel line. Repeat this operation three times, then check for fuel leakage at any point in the fuel line.
Exhaust Pipe and Muffler Replacement
Note. Use new gaskets and new self-locking nuts when reassembling.
