CAUTION: Vehicle cooling systems are filled with Motorcraft Premium Engine Coolant VC-4-A (in Oregon VC-5, in Canada CXC-10) or an equivalent meeting Ford specification ESE-M97B44-A. NOTE: Less than 80% of the coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement. 1. Release the pressure in the cooling system by slowly turning the pressure relief cap one half to one turn counterclockwise to the first stop on the filler neck. When the pressure has been released, remove the pressure relief cap. 2. Raise and support the vehicle. For additional information, refer to Section 100-02 . 3. Remove the front splash shield. 4. Place a suitable container below the radiator draincock. Drain the coolant. 5. Close the radiator draincock when finished. Filling and Bleeding With RADKITPLUS 1. Using the special tool, install the RADKITPLUS and follow the RADKITPLUS manufacturer’s instructions to fill and bleed the cooling system. Filling Without RADKITPLUS CAUTION: Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level. When adding engine coolant, use a 50/50 mixture of engine coolant and clean, drinkable water. To maintain the integrity of the coolant and the cooling system: * Add Motorcraft Premium Engine Coolant VC-4-A (in Oregon VC-5, in Canada CXC-10) or equivalent meeting Ford specification ESE-M97B44-A. * Do not add Motorcraft Specialty Engine Coolant VC-2 or an equivalent meeting Ford specification WSS-M97B44-D. Mixing coolants may degrade the coolant’s corrosion protection. * Do not add alcohol, methanol, brine or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing. * Do not mix with recycled coolant unless it meets the requirement of specification ESE-M97B44-A. Not all coolant recycling processes meet this specification. Use of such a coolant may harm the engine and cooling system components. 1. Install the front splash shield. 2. Lower the vehicle. 3. Fill the degas bottle with the correct engine coolant mixture. 4. Install the pressure relief cap. 5. Move the temperature blend selector to the full warm position. 6. WARNING: Do not stand in line with or near the engine cooling fan blade when revving the engine. Run the engine until it reaches operating temperature. 7. Add the correct coolant mixture to the degas bottle until the coolant level is between the COOLANT FILL LEVEL marks. 8. Turn off the engine and allow the cooling system to cool. Recheck the coolant level and fill the cooling system to the FULL mark on the degas bottle. 9. WARNING: Do not stand in line with or near the engine cooling fan blade when revving the engine. Repeat Steps 3 through 8 until the reservoir level is OK. Bleeding Without RADKITPLUS 1. Bleed the cooling system as follows: * Select the maximum heater temperature and blower motor speed settings. Position the control to discharge air from the A/C vents in the instrument panel. * WARNING: Do not stand in line with or near the engine cooling fan blade when revving the engine. Start the engine and allow it to idle. While the engine is idling, feel for hot air from the A/C vents. * CAUTION: If the air discharge remains cool and the engine coolant temperature gauge does not move, the engine coolant level is low in the engine and must be filled. Stop the engine, allow it to cool and fill the cooling system. Start the engine and allow it to idle until the normal operating temperature is reached. Hot air should discharge from the A/C vents. The engine coolant temperature gauge should maintain a stabilized reading in the middle of the NORMAL range and the upper radiator hose should feel hot to the touch. * Shut the engine off and allow it to cool. * Check the engine for coolant leaks. * Check the engine coolant level in the degas bottle and fill it as necessary.

The PCV system is designed to prevent blow-by gas from escaping to the atmosphere by drawing it directly into the intake manifold. The PCV valve contains a spring-loaded plunger which is lifted in proportion to intake manifold vacuum. Under high vacuum, blow-by is returned directly to the manifold through the breather chamber and PCV valve with fresh air. When intake manifold vacuum decreases (wide open throttle) and vacuum in the air cleaner increases, the PCV valve closes and the blow-by is returned through the cylinder head cover breather hose and into the air cleaner. The PCV valve also acts as a check valve when the engine backfires to prevent crankcase explosion. Fig. 1: PCV system components-1984-87 1.5L engines Fig. 2: PCV system components-1988-91 1.6L engines Fig. 3: PCV system components-1992-95 engines Fig. 4: PCV system components-1984-87 carbureted engines SERVICE Positive Crankcase Ventilation (PCV) Valve For PCV valve removal, refer to Routine Maintenance of this information. 1. Locate the PCV valve. With the engine running at idle, use pliers to pinch the PCV hose between the valve and the intake manifold. It should be possible to hear the spring loaded valve click shut. 2. If no click is heard, remove the valve from the engine but leave it connected to the intake manifold. A hissing sound should be heard and vacuum should be felt at the valve inlet. 3. If no vacuum is felt, remove the valve from the intake manifold hose. The engine should stall or almost stall. This will indicate a stuck valve or clogged hose. Check the breather hose for clogging or leaks and replace any defective parts. Exhaust Gas Recirculation (EGR) System FUEL INJECTED ENGINES General Information See Figure 3 The Exhaust Gas Recirculation (EGR) system is used to control emissions measured at the tailpipe. Components included are the EGR valve and controls. The EGR system uses a poppet type valve to regulate the amount of exhaust gas flowing into the intake manifold. The flow path is cast into the cylinder head and does not use any external tubing. A control solenoid valve regulates the amount of vacuum to the EGR valve. A Constant Volume Control (CVC) valve provides a constant amount of vacuum to the control solenoid valve over a wide range of engine vacuum. When servicing or repairing any part of the emissions system, it is absolutely essential to check for any obvious mechanical faults or failures. Remember, a trouble code only indicates which sensor or circuit is affected by the problem. Simple mechanical faults such as a vacuum leak or poor electrical connection can cause a fault code. The EGR valve is not simply open or closed but is modulated by controlling the amount of engine vacuum to the valve diaphragm, up to a maximum of 8 in. Hg of vacuum. The EGR valve has a sensor in the top of the valve that reports valve lift to the ECU (same as ECM, 1992-95). The ECU modulates the position of the control solenoid valve to control the EGR valve lift according to an internal program. Upstream of the control solenoid valve, the CVC provides a constant supply of vacuum so EGR control is precise under all manifold vacuum conditions

PRE-INSTALLATION PROCEDURE General Motors vehicles came with many different engine and transmission combinations. This section is intended to verify that all the correct components are in place prior to installation. If the vehicle is currently equipped with a small block Chevrolet V8, then the engine isolator for the current application will work with the Edelbrock Adaptor plates. See the next page for further notes on various applications. A-BODY APPLICATIONS: 1964 – 1967: Vehicles that are being converted from six cylinder or a non-Chevrolet engine can use engine frame stands for the 283 to 327 from a salvage yard or reproduction suppliers such as OPGI and Yearone; engine isolators can be of the OEM rubber type from a parts supplier or polyurethane safety mounts from Energy Suspension: part #3.1114 (zinc plated), or #3.1115 (chrome). 1964 – 1967 applications will require mildly slotting the engine frame stand mounting holes, as shown in Figures 1 and 2. FIGURE 1 FIGURE 2 – 1968 – 1972: From 1968 to 1972, Chevrolet used two different frame stands with matching engine isolators. Type one is the 307 (and some early 1968 327′s), while type two includes all engines from the later 1968 327′s through to the 454, encompassing all engine sizes in-between. If you have obtained frame stands from another vehicle, use the following procedure to identify your mount system: measure the ears of the engine isolator where the engine mounting bolt goes, the inside dimension is 2 5/8″for the 307 cid (Figure 3) and 2 3/8″for the larger sized engine (Figure 4). Frame stands for the late 327,350 to 454 are also available from reproduction suppliers such as OPGI and Yearone, engine isolators can be of the OEM rubber type from a parts supplier or polyurethane safety mounts from Energy Suspension: part #3.1114 (zinc plated) #3.1115 (chrome) for the 307, part #3.1117 (zinc plated) or #3.1118 (chrome) for the late 327 to the 454. FIGURE 3 (307) FIGURE 4 (350 et al) F-BODY AND X-BODY APPLICATIONS: 1967 – 1969 F-body and 1968 – 1974 X-body: Vehicles that are being converted from six cylinder or a non-Chevrolet engine will require engine isolators that match the engine frame stand. There are a variety of styles depending on engine size and model year, so get the engine isolators and frame stands which are available from reproduction suppliers such as Classic Industries and Yearone. Engine isolators can be of the OEM rubber type from a parts supplier or polyurethane safety mounts from Energy Suspension. There are two basic types of engine isolators; to identify them measure the distance between the tab for the engine mount through bolt, if it is 2-5/8″use Energy Suspension #3.1114 (zinc plated) #3.1115 (chrome), if the distance is 2-3/8″use #3.1117 (zinc plated) #3.1118 (chrome).

Carbureted Fuel System GENERAL INFORMATION On these vehicles, the engine management system is considered part of the emission control system. The major components include the carburetor(s), feedback control system, the air injection system, a throttle control system and the EGR system. The system consists of sensors and switches that feed information to the Electronic Control Unit (ECU), which will then operate several solenoid valves to maintain the ideal air/fuel ratio under all conditions. As useful as the tests found in this section are, the first step in repair or service to engine management systems is still to gain as much information as possible about the problem; when and under what conditions it occurs. At highway speed? At idle only? Only under heavy load or hard acceleration? Wet weather? Defining the problem will eliminate many systems from consideration and possibly point to the affected system. Before diving into an extended electrical diagnosis, take the time to review the basics. Check every vacuum line for cracks or leaks. Check every electrical connector for corrosion or loose pins. Quite often, simply unplugging and reconnecting a connector will break up corrosion on the pins and restore the circuit. Watch out for poor grounds, particularly if the car has experienced major bodywork. COMPONENT TESTING Air Injection System The purpose of this system is to supply oxygen to the exhaust stream at a point in the exhaust manifold that is hot enough to burn off some of the hydrocarbon emissions. The main component is an air suction valve. The valve is spring loaded to stay closed, with engine vacuum supplied to a diaphragm that reduces the spring pressure and allows the reeds to open. The ECU regulates the engine vacuum to the diaphragm by operating a solenoid valve. 1. With the engine at normal operating temperature and at idle, remove the air cleaner and listen for a bubbling sound at the air suction port. There should be no sound at idle, meaning the air suction valve is closed. 2. If the noise is heard at the air suction port, disconnect the vacuum hose at the air suction valve and connect a vacuum gauge to the hose. There should be no vacuum. If there is vacuum and the noise stops, the problem is in the control system. If there is no vacuum and the bubbling sound is still there, the air suction valve is defective and must be replaced. 3. To test the valve, draw a vacuum at the air suction valve diaphragm and listen for a bubbling sound at the air suction port. If no sound is heard, the air suction valve or diaphragm is faulty.
