A/C SYSTEM GENERAL SERVICING 1999 Dodge Pickup R1500 1999 GENERAL SERVICING A/C System General Servicing All Models USING R-134a REFRIGERANT HANDLING/SAFETY PRECAUTIONS 1) Always work in a well-ventilated, clean area. Refrigerant is colorless and invisible as a gas. Refrigerant is heavier than oxygen and will displace oxygen in a confined area.
Page 129
To prevent refrigerant cross-contamination, use following methods to identify R-134a based systems and components. Fittings & "O" Rings All R-134a based A/C systems use 1/2" - 16 ACME threaded fittings (identifiable by square threads) and quick-connect service ports. See Fig. 1. Fig.
Page 130
of underhood labels with R-134a refrigerant clearly printed on labels. See Fig. 2. The underhood label used on Ford Motor Co. vehicles is Yellow. See Fig. 3. Most manufacturers will identify refrigerant type with labels affixed to compressor. Before servicing an A/C system, always determine which refrigerant is being used.
Page 131
Refrigerant R-12 based systems use mineral oil, while R-134a systems use synthetic Polyalkylene Glycol (PAG) oils. Using a mineral oil based lubricant with R-134a will result in A/C compressor failure due to lack of proper lubrication. Following are the most common R-134a refrigerant oils used by most domestic vehicles: Chrysler Corp., Eagle &...

service valve (3/8" - 24 threads) is different from thread size on low-side service valve (7/16" - 20 threads). Special adapters are required to make this connection. See Fig. 5. These adapters are available in 45-degree and 90-degree angles in addition to straight- fixed and flexible adapters.

Page 137
Because R-134a is not interchangeable with R-12, separate sets of hoses, gauges, and recovery/recycling equipment are required to service vehicles. This is necessary to avoid cross-contamination and damaging system. All equipment used to service systems using R-134a must meet SAE standard J2210. The service hoses on the manifold gauge set must have manual (turn wheel) or automatic back-flow valves at the service port connector ends.
Page 138
2) Ensure service hoses are equipped with valve core depressor to match Schrader valve. If not, install special adapters for this purpose. If the high-side service hose connector will not fit on high-side Schrader valve, a special adapter must be used. See SPECIAL VALVE CONNECTORS.

DRIVE SHAFTS & "U" JOINTS - RWD 1999 Dodge Pickup R1500 1998-99 Drive Axles CHRY - Drive Shafts & "U" Joints - RWD Trucks Dakota, Ram Pickup, Ram Van/Wagon DESCRIPTION Drive shafts are balanced, tubular shafts with "U" joints attached at each end. Flanges or yokes are used to connect drive shaft "U"...
Page 458
Apply multipurpose lubricant (NLGI grade 2 EP) to "U" joints and slip joint fittings. INSPECTION Abnormal vibration and noise can come from many driveline sources. Drive shaft vibration/noise increases with vehicle speed (MPH). A vibration that occurs within a specific speed is not caused by drive shaft imbalance.
Page 459
Fig. 2: Checking Phase Alignment Of One-Piece Drive Shaft 2-Piece Shafts 1) On most models with 2-piece drive shafts, proper yoke phasing is accomplished by keys on drive shaft spline and keyway in slip joint splines. Drive shafts of this type will fit together only one way.
Page 460
1) On drive shafts greater than 30" in length, measure runout 3" from transmission flange/yoke, center bearing yoke and pinion flange using dial indicator. Maximum runout for Ram Pickup is .030" (. 76 mm) at front and rear end of drive shaft and .035" (.89 mm) at center of drive shaft.
Page 461
4) Difference between 2 measured angles is drive shaft front angle. See Fig. 5. Compare front and rear angles. Allowable difference between angles is plus or minus one degree. If difference of angles is greater than specified, adjustment is necessary. See ADJUSTING VERTICAL ANGLE.
Page 462
perpendicular to each other in vertical plane. See Fig. 6. With non- parallel or broken-back type installation, working angles of "U" joints of given drive shaft must be equal (angle "A" = angle "B"). Fig. 6: Identifying Broken-Back Type Drive Shaft Courtesy of Chrysler Corp.

inspection procedures. A visual inspection is made to determine if any required emission control devices are missing, modified or disconnected. Missing, modified or disconnected systems must be made fully operational before a vehicle can be certified. POSITIVE CRANKCASE VENTILATION (PCV) PCV controls the flow of crankcase fumes into the intake manifold while preventing gases and flames from traveling in the opposite direction.
Page 604
Fig. 3: Typical Thermostatic Air Cleaner System FUEL EVAPORATIVE SYSTEM (EVAP) The EVAP system allows for proper fuel system ventilation while preventing fuel vapors from reaching the atmosphere. This means that vapors must be caught and stored while the engine is off, which is when most fuel evaporation occurs.
Page 605
Fig. 4: Typical Fuel Evaporative System CATALYTIC CONVERTERS Oxidation Catalyst (OC) This type of converter is the most common. It may use pellets or monolith medium, depending upon application. See Fig. 5. Platinum and palladium (or platinum alone) are used as catalyst in this type of converter.

converter with the exception of the catalyst. See Fig. 5. The TWC converter uses rhodium, with or without platinum, as its catalyst. Rhodium helps reduce NOx emissions, as well as HC and CO. Visually check for presence of catalytic converter(s). Also check for presence of any required air supply system for the oxidizing section of the converter.

Single Diaphragm EGR Valve This type uses a single diaphragm connected to the valve by a shaft. Diaphragm is spring-loaded to keep valve closed in the absence of vacuum. As throttle valves open and engine speed increases, vacuum is applied to the EGR vacuum diaphragm, opening the EGR valve. This vacuum signal comes from a ported vacuum source.
Page 608
Verify EGR valve is present and not modified or purposely damaged. Ensure thermal vacuum switches, pressure transducers, speed switches, etc., (if applicable) are not by-passed or modified. Ensure vacuum hose(s) to EGR valve is not plugged. Fig. 8: Typical Dual Diaphragm EGR Valve Courtesy of General Motors Corp.

switches, etc., (if applicable) are not by-passed or modified. Ensure vacuum hose(s) to EGR valve is not plugged. Fig. 9: Typical Positive Backpressure EGR Valve Courtesy of General Motors Corp. Negative Backpressure EGR (BP/EGR) Valve This type has the same function as the positive BP/EGR valve except valve is designed to open with a negative exhaust backpressure.
Page 610
Fig. 10: Typical Negative Backpressure EGR Valve Courtesy of General Motors Corp. Digital EGR Valve The digital EGR valve operates independently of engine manifold vacuum. This valve controls EGR flow through 3 orifices.
Page 611
These 3 orifices are opened and closed by electric solenoids. The solenoids are, in turn, controlled by the Electronic Control Module (ECM). When a solenoid is energized, the armature with attached shaft and swivel pintle is lifted, opening the orifice. See Fig. 11. The ECM uses inputs from the Coolant Temperature Sensor (CTS), Throttle Position Sensor (TPS) and Mass Airflow (MAF) sensors to control the EGR orifices to make 7 different combinations for...

remote vacuum regulator. The internal solenoid is normally open, which causes the vacuum signal to be vented off to the atmosphere when EGR is not controlled by the Electronic Control Module (ECM). The solenoid valve opens and closes the vacuum signal, controlling the amount of vacuum applied to the diaphragm.
Page 613
Spark control systems are designed to ensure the air/fuel mixture is ignited at the best possible moment to provide optimum efficiency and power and cleaner emissions. Ensure vacuum hoses to the distributor, carburetor, spark delay valves, thermal vacuum switches, etc., are in place and routed properly.
Page 614
Fig. 14: Typical Pulsed Secondary Air Injection System Courtesy of General Motors Corp. OXYGEN SENSOR (O2) The O2 sensor is mounted in the exhaust system where it monitors oxygen content of exhaust gases. Some vehicles may use 2 O2 sensors. The O2 sensor produces a voltage signal which is proportional to exhaust gas oxygen concentration (0-3%) compared to outside oxygen (20-21%).
Page 615
EARLY FUEL EVAPORATION (EFE) The EFE valve is actuated by either a vacuum actuator or a bimetal spring (heat-riser type). The EFE valve is closed when engine is cold. The closed valve restricts exhaust gas flow from the exhaust manifold. This forces part of the exhaust gas to flow up through a passage below the carburetor.
Page 616
If equipped, the EMR light (some models may use a reminder flag) reminds vehicle operator that an emission system maintenance is required. This indicator is activated after a predetermined time/mileage. When performing a smog check inspection, ensure EMR indicator is not activated. On models using an EMR light, light should glow when ignition switch is turned to ON position and should turn off when engine is running.
