How to replace an intake manifold gasket on a 1996 gmc jimmy


Hello,

Here is a detailed summary on the procedure of how to replace the intake manifold gasket on a 1996 gmc jimmy;
REMOVING THE UPPER INTAKE MANIFOLD(PLENUM)
STEP 1 Disconnect Battery (may not be absolutely necessary, but a good practice to avoid shorting a positive wire to ground).


STEP 2 Remove serpentine belt.

STEP 3 Drain the coolant.

STEP 4 Remove air cleaner ducting and disconnect wires.

STEP 5 Disconnect throttle linkage and bracket.

STEP 6 Disconnect cruise control cable.

STEP 7 Remove brake booster vacuum hose at manifold.

STEP 8 Remove PCV hose.

STEP 9 Remove ignition coil and bracket.

STEP 1O Remove purge solenoid and bracket.

STEP 11 Relieve fuel pressure at test port.

STEP 12 Remove fuel lines and bracket.

STEP 13 Remove upper intake manifold.

REMOVING THE LOWER INTAKE MANIFOLD
STEP 1 Remove the distributor and label the spark plug wires.

STEP 2 Remove heater hoses and bypass hose.

STEP 3 Remove upper radiator hose.


STEP 4 Remove EGR valve?

STEP 5 Remove sensors and bracket on right side.

STEP 6 Remove EGR tube, clamp and bolt.

STEP 7 Remove PCV valve (and replace).

STEP 8 Unbolt A/C compressor and move it aside.

STEP 9 Loosen compressor bracket and slide forward, but do not remove it.

STEP 10 Remove alternator bracket bolt (or remove alternator and set aside)

STEP 11 Unplug all vacuum lines from intake manifold.


STEP 12 Unplug all electrical connectors from manifold.

STEP 13 Take note of the intake manifold bolts and mark the location of the bolts.


STEP 14 Remove intake manifold bolts, and manifold.

STEP 15 Clean mating surfaces

THE MAIN INSTALLATION
STEP1 Set the new gaskets in place and apply silicone to flat areas on front and rear of engine block.

STEP2 Apply thread locking compound to manifold bolts.

STEP 3 Install the manifold and tighten bolts to 35 ft-lbs, in proper sequence.

STEP4 Install the distributor.

STEP5 Install the upper intake manifold.



The remaining installation procedures are basically the reverse of removal.


Have a nice day.

Probably a vacuum line. Most heater controls are ran by vacuum and their is one vacuum line that goes from the troddle body to the firewall on the passenger side of the car. Check for a broken hose.

Vacuum lines


Hello, I have the 1993 Ford Festiva shop manual in front of me. The vacuum hose on the Fuel Pressure Regulator goes to the intake manifold. The manual says that the fuel pressure is maintained at a constant 36.3 psi, and when the engine vacuum drops (caused by high fuel demand) it causes the fuel pressure to increase inside the regulator. There should be a vacuum diagram on the bottom side of the hood that will help to show you what vacuum port on the manifold that it attaches to. If the decal is gone, look on the intake manifold for a vacuum port that is open and causing a vacuum leak. I hope this helps.

  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Properly relieve the fuel system pressure.
  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.
