SOURCE: changing spark plugs 2003 Impala 3.4 eng. i.e. removing and reinstalling upper intake manifold

I have a 2003 chevy Impala and it's not so difficult. Try using a small ratchet that fits in the palm of your hand, I can't remember what it is called. To install the plugs use an extension and put a couple of the card board pieces from one of the spark plug boxes in between the new spark plug and the spark plug puller socket, this will hold the new plug in place while you work with the extension. When screwing in the plug you will have to go by feel so move the extension back and forth like a light jiggle while turning to avoid cross threading the plug. After the plug is tightened attach the ratchet and slightly torque into place.

- Position the rocker arms in their original locations and tighten to the proper specifications.

- Install lower the intake manifold attaching bolts. Apply sealant or equivalent thread locking compound to the threads of bolts. Tighten the vertical bolts first, then the diagonal bolts to 115 inch lbs. (13 Nm).

- Install the upper intake manifold and tighten the mounting bolts to 18 ft. lbs. (25 Nm).

Hope helps (remember to rate this).

How to replace the intake manifold? I have a 96 grand cherokee v8, unable to replace the thermostat housing to the manifold because one of the screw holes cracked off on the manifold.


Position The Intake Manifold Gasket On The Engine.Dowels May Be Provided To Hold The Gasket In Place During Manifold Installation.. The Use Of Silicone Sealer Is Required. Especially Where The Front And The Rear Seals Meet The Side Gaskets On V-type Engines. Installing An Intake Manifold On V-type Engines Can Be Difficult. It Is Critical That You Use Sealer Properly On The Engine To Prevent Vacuum,Coolant, And Oil Leaks.

Start All The Fasteners By Hand Before Tightening. This Will Aid In Bolt Hold Alignment. Then Torque The Intake Manifold Fasteners To Specifications. Use The Specific Torque Pattern Given In The Service Manual.. Basically The Pattern Will Be A Crisscross Pattern

Intake manifold gasket / replace


3.8L Engine

NOTE The 3.8L (VIN K) non-supercharged engine uses a two-piece intake manifold consisting of an upper air plenum which mounts the throttle body and a lower intake manifold assembly which houses the fuel injectors. The 3.8L (VIN 1) supercharged engine uses a similar lower intake manifold. The supercharger serves as the upper manifold.
Lower Manifold

NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold. Remove the upper intake manifold to service the lower intake.
The 3.8L (VIN 1) supercharged engine uses a manifold similar to the 3.8L (VIN K), but the supercharger serves as the upper manifold.
  1. Disconnect the negative battery cable.
  2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
  3. Remove the upper intake manifold using the procedure above.
  4. Remove the EGR outlet pipe from the intake manifold.
  5. Detach the engine coolant temperature sensor wiring harness from the sensor.
  6. Remove the lower intake manifold bolts and carefully lift off the manifold.

To install:


0900c15280269f1b.jpg enlarge_icon.gifenlarge_tooltip.gif Fig. Lower intake manifold bolt torque sequence-3.8L (VIN K) engine
  1. Clean all parts well with degreaser, especially the gasket seal surfaces on the upper and lower manifold pieces and between the lower manifold and the cylinder heads..
  2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Apply thread-locking compound to the bolt threads. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 11 ft. lbs. (15 Nm). Follow the toque sequence, starting in the center, then working outwards in a circle.
  3. Install the remaining components in the reverse order of the removal process.

Upper Intake Manifold (Plenum)
  1. Disconnect the negative battery cable.
  2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
  3. Tag for identification, then remove the right side spark plug wires.
  4. Disconnect the ignition wires from the fuel rail.
  5. Remove the fuel rail. Please see Section 5.
  6. Remove the cable bracket from the intake manifold.
  7. Remove the throttle body.


NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold.
  1. Remove the upper intake manifold bolts and carefully lift the upper intake manifold from the engine.

  2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 89 inch lbs. (10 Nm). Follow the torque sequence, starting in the center, then working outwards in a circle.
  3. Install the remaining components in the reverse order of the removal process.

Leaking anti-freeze from my intake gasket


The corners of the intake manifold have coolant pasages. The lower intake manifold gasket will need to be replaced. There is an updated manifold gasket, manifold bolts, and torque specification. Call the chevrolet dealership and see if they will extend the warrant on this repair. It is a very common problem with this engine. Thanks Steve

  3. Drain the coolant system.
  4. Remove or disconnect the following:
    • Negative battery cable
    • Air cleaner fresh air hose
    • Positive Crankcase Ventilation (PCV) valve hose
    • Fuel line from the rail
    • Throttle cable from the throttle body
    • Throttle cable bracket nuts
    • Fuel injector electrical connectors
    • Throttle Position (TP) sensor electrical connectors
    • Idle Air Control (IAC) valve electrical connectors
    • Manifold Absolute Pressure (MAP) sensor electrical connectors
    • Exhaust Gas Recirculation (EGR) valve electrical connectors
    • Heater hose from the intake manifold outlet
  5. Position the wiring harness over the brake master cylinder
  6. Remove or disconnect the following:
    • Intake manifold support bracket bolt
    • Label the vacuum line for proper assembly
    • Drive belt
    • Power steering pump
    • Upper intake manifold bolts
    • Evaporative Emissions (EVAP) canister purge valve solenoid vacuum hose
    • Brake booster vacuum hose
    • Lower intake manifold bolts
    • Intake manifold
    To install:
  7. Thoroughly clean all gasket mating surfaces. Be careful not to damage or score the aluminum surface. If replaced, use Loctite® 290, to seal the new PCV valve inlet tube into the manifold. NOTE: Refer to Section 1 of this manual for the intake manifold torque sequence illustration. The illustration is located after the Torque Specification Chart.
  8. Install or connect the following:
    • New gasket and manifold. Torque the nuts in sequence to 22 ft. lbs. (30 Nm).
    • Power steering pump. Torque the fasteners to 27 ft. lbs. (38 Nm).
    • Drive belt.
    • Heater hose and install the manifold support bracket bolt. Tighten the bolt to 22 ft. lbs. (30 Nm).
    • Lubricate the male ends of the fuel lines with a few drops of clean engine oil, then connect the fuel supply and return lines.
    • Fuel line(s) in the retaining bracket. Torque the mounting screw to 36 inch lbs. (4 Nm).
    • Throttle cable to the throttle body and attach the accelerator cable bracket. Torque the bolts to 22 ft. lbs. (30 Nm).
    • Reposition the wiring harness and connect the wiring and vacuum hoses to their original locations. The harness leads to the TP sensor and EGR solenoid must be routed between the intake manifold runners.
    • Negative battery cable
  9. Fill the coolant system.
  10. Prime the fuel system by cycling the ignition ON for 5 seconds and OFF for 10 seconds a few times without cranking the engine.
  11. Start the engine, check for leaks, and repair if necessary.
