1984-1998 Jeep Wagoneer/ Commando/ Cherokee Emission Controls Crankcase Ventilation System (PCV/CCV)

CCV Fitting See Figures 2 and 3 1. With the engine running, remove the CCV fitting. a. If the fitting is not plugged, a hissing noise will be heard as air passes through the valve. A strong vacuum should also be felt when a finger is placed over the fitting. b. Install the CCV fitting. c. Remove the fresh air hose from the air cleaner assembly and loosely hold a piece of paper over the open end of the hose. After allowing about one minute for the crankcase pressure to reduce, the paper should be sucked against the opening with a noticeable amount of force. 2. Turn the engine OFF . Remove the metered orifice fitting, and check for a plugged condition. A clicking noise should be heard to indicate that the valve mechanism is free. 3. If the crankcase ventilation system meets the tests in Steps 1 and 2 above, no further service is required. If not, the CCV fitting must be cleaned and the system checked again. 4. If Step 1c fails when the CCV fitting is cleaned, it will be necessary to replace the molded vacuum hose with a new one, and to clean the metered orifice port. 5. Clean or replace the engine air cleaner filter element with a new one-for more details, refer to the air cleaner procedure located in General Information & Maintenance. Fig. 2: CCV system diagram for 4.0L engine Fig. 3: CCV system diagram for the 2.5L engine Evaporative Emission Control System OPERATION The evaporative emission control system prevents the release of unburned hydrocarbons, from gasoline or gasoline vapor, into the atmosphere. When pressure in the fuel tank is below 3 psi (20 kPa), the pressure relief/rollover valves open allowing fuel vapors to flow to the evaporative canister where they are absorbed by a charcoal mixture. This prevents excessive pressure buildup in the fuel system. Most canisters are equipped with a calibrated orifice at the inlet to the canister.

2000 Ford Ranger Cooling System Draining Filling and Bleeding Repair Manual

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 lower radiator cover. 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 such as VC-2 or an equivalent meeting Ford specification WSS-M97B44-D. Mixing coolants can degrade the coolant’s corrosion protection. * Do not add alcohol, methanol, or 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 coolants unless they meet the requirements of Ford specification ESE-M97B44-A or WSS-M97B51-A1. Not all coolant recycling processes meet these Ford specifications. Use of such coolants can harm the engine and cooling system components. All engines 1. Install the lower radiator cover.

Draining and Filling Cooling System Notes Draining and Filling Cooling System Draining Procedure Important: Do NOT add any engine coolant supplement sealant pellets to the cooling system. Drain and refill the engine cooling system every 5 years or 240 000 km, (150,000 ml) , whichever occurs first. 1. Park the vehicle on a level surface. 2. Remove and clean the coolant recovery reservoir. Caution: To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if radiator cap or surge tank cap its removed while the engine and radiator are still hot. 3.1. Slowly rotate the cap counterclockwise to the detention tab. Do not press down while rotating pressure cap. 3.2. Wait until any residual pressure, indicated by a hissing sound, is relieved. 3.3. After all hissing stops, press down on the radiator cap and rotate the cap counterclockwise in order to remove the cap. Important: Recover and store used coolant in a used coolant holding tank and submit the used coolant for recycling on a regular basis. Do NOT pour used coolant down the drain. Ethylene glycol antifreeze is very toxic. Disposing of ethylene glycol into the sewer system or ground water is both illegal and ecologically unsound. 4. Place a drain pan under the radiator drain cock in order to collect all of the used coolant. 5. Open the radiator drain cock. If only partial cooling system draining is required, drain enough coolant to perform the procedure 6. Open the air bleed valve on the thermostat housing 2 full turns. 7. Open the air bleed valve above coolant pump 2 full turns. 8. Place a drain pan under the engine block drains in order to collect the used coolant. Important: Allow the coolant to drain completely

Set-up & Procedure: 1. Ensure the cooling system is cool and not pressurized. Carefully remove the radiator or coolant bottle pressure cap (Fig. 1). 2. Check to see that the radiator or coolant bottle is filled to the proper level, and check hoses for visual damage or leaks. Fill and repair as necessary prior to testing. 3. Select the correct Cooling System Adapter for the application. 4. Apply water or coolant to the rubber gasket and/or o-ring on the adapter, and install the adapter in place of the pressure cap (Fig. 2). 5. Secure one end of the clear hose to the pressure pump using the compression nut (Fig. 3). 6. Secure the second end of the hose to the cooling system test adapter using the compression nut (Fig. 4). 7. Note the operating pressure of the cooling system indicated on the cap or in the vehicle repair manual. 8. Operate the Pressure Pump until the needle on the pressure gauge moves to the arrowhead at the end of the colored band indicating the appropriate pressure range of the cap (see Chart A). Caution : Do not pressurize the cooling system beyond the appropriate color of arrowhead for the system being tested. 9. Monitor the gauge for at least two minutes. If the pressure reading drops, a leak is present. 10. With the system still pressurized, perform a visual inspection of the entire cooling system. Check hoses and connections for seepage, which would indicate a leak. Return to the gauge and check the reading once more.
