Place a clean, sealable container under the radiator drain and remove the drain plug with a socket wrench. Allow the coolant to drain into the container and seal the container for later use. Replace the drain plug.

Remove the filler cap on the fuel tank to relieve the pressure in the fuel tank. Connect fuel pressure gauge T80L-9974-B to the pressure relief valve on the fuel supply manifold. Place the tube of the fuel pressure gauge into a container approved for gasoline and open the valve on the pressure gauge. Drain the excess fuel into the container to relieve the pressure in the fuel system.

Disconnect the battery cable from the negative terminal with a socket wrench. Remove the intake air temperature sensor and the air intake tube. Detach the cables for the cruise control and accelerator. Disconnect the bracket for the accelerator.

Detach the electrical connectors for the exhaust gas recirculation and vacuum regulator solenoids, if your vehicle is so equipped. Disconnect the electrical wires to the spark plugs and the ignition coil. Disconnect any additional vacuum lines needed to access the lower intake manifold.

Disconnect the positive crankcase ventilation valve from the crankcase with a socket wrench. Detach the electrical connector for the throttle position sensor and idle air control valve. Remove the exhaust gas recirculation valve. Disconnect the bracket for the wiring harness of the engine control sensor and push it out of your way.

Remove the upper intake manifold with a socket wrench. Detach the fuel lines from the fuel supply manifold and disconnect the electrical connector for the engine coolant temperature sensor. Remove the fuel supply manifold and fuel injectors from the lower intake manifold as an assembly.

Disconnect the upper radiator hose and heater hose from the radiator. Remove the lower intake manifold from the engine with a socket wrench.

Disconnect the negative battery cable from the battery, using the socket wrench and the appropriate sized socket.

Locate the ERG valve on your engine. It will either be bolted to the intake manifold or the exhaust manifold depending on your 3.8 engine.

Disconnect the air supply hose, vacuum hose and/or electrical connections from the EGR valve. You might need the screwdrivers for this step.

Remove all the bolts that mount the EGR valve to the intake manifold/exhaust manifold, using the socket wrench with the appropriate size socket.

Remove the old EGR valve and gasket.

Install the new gasket and EGR valve after making sure the mounting surfaces are clean. You may use the putty knife for this step.

Attach all hoses, wiring and bolts that were previously disconnected.

Reconnect the negative battery cable to the battery, and then take the vehicle out on a test drive.

Park the 1985 Chevrolet Camaro in a safe working area and open the hood. Shut the motor off and engage the parking brake.

Raise the hood and prop it in place. Locate the distributor cap near the back of the engine. All of the spark plug wires are attached to the top of the distributor cap.

Mark a straight line on the front side of the distributor cap with a marker. Also mark another straight line on the front side of the distributor cap base directly below the other line. This will help you remember the exact setting of the distributor before moving it.

Loosen the hold-down screws on the bottom side of the distributor with a Phillips-head screwdriver.

Grab the distributor with both hands and turn it clockwise to retract the timing. Turn the distributor counterclockwise to advance the timing. Be sure to make short turns when turning the distributor. Once the distributor is timed to your liking, screw the hold-down screws back down tight with the Phillips-head screwdriver.

Disconnect the cable on the negative battery terminal with a socket wrench. Detach the accessory drive belt.

Turn the crankshaft by hand to align the timing marks on the crankshaft and both camshafts. This places the first cylinder of the the engine in the top dead center position. Disconnect the crankshaft position sensor from the lower left side of the engine.

Place Tool No. 3242 onto the crankshaft and tighten it slightly to hold the crankshaft in place. Disconnect the upper cover for the timing belt with a socket wrench. Remove the vibration damper from the crankshaft, and remove the lower cover for the timing belt.

Loosen the bolts on the camshaft sprockets with a socket wrench. Release the sprockets from the ends of the camshafts, and remove the sprockets from the camshaft. Relieve the tension on the timing belt with the tensioner roller, and disconnect the timing belt from the pulleys.

Place the camshaft sprockets onto the camshafts. Install Tool No. 3243 into the alignment flanges of the camshaft, and fasten the camshaft sprockets to the camshafts. Place the new timing belt over the crankshaft sprocket, camshaft sprockets, idler rollers and timing belt tensioner in that order.

Tighten the roller on the camshaft tensioner so that you can just twist the timing belt between the tensioner and the left camshaft sprocket by 1 / 4 turn. Tighten the mounting bolts for the camshaft sprockets to 33 ft. lbs. with a torque wrench.

Connect the lower cover for the timing belt with a socket wrench and attach the vibration damper to the crankshaft. Remove Tool No. 3242 from the crankshaft. Connect the crankshaft position sensor to the engine, and attach the accessory drive belt. Connect the cable to the negative battery terminal.
