TRANSMISSION & TRANSFER CASE CAPACITIES
| CAUTION | DO NOT use transmission fluid that indicates a dual use; such as Mercon and Mercon V in a transmission which requires Mercon. Mercon V is a synthetic fluid and MUST NOT be used in applications that require Mercon or transmission damage may occur. Dual-usage fluids may be used in transmissions that require Mercon V fluid only. |

BELT DEFLECTION SPECIFICATIONS
Diesel Engines
Note. On diesel engines, a mechanical compression testing procedure is not available from manufacturer.
To diagnose possible cylinder compression loss, perform CRANKCASE PRESSURE TEST under ENGINE PERFORMANCE DIAGNOSIS in SYSTEM & COMPONENT TESTS - EEC-V - DIESEL article and/or KOER CYLINDER CONTRIBUTION SELF-TEST under QUICK TEST in SELF-DIAGNOSTICS - EEC-V - DIESEL article.
Gasoline Engines
Note. DO NOT use ignition switch to crank engine. Fuel injection and coils will activate and may cause damage.
Check engine compression with engine at normal operating temperature, all spark plugs removed (on dual plugs, remove exhaust side only), and throttle wide open. Ensure crankcase is full and oil is of correct viscosity. With compression gauge installed, use remote starter switch to crank engine.
Crank engine at least 5 revolutions, and record highest reading. Repeat procedure for all cylinders, using approximately same number of revolutions. Lowest compression reading should not be less than 75 percent of highest compression reading. No cylinder compression reading should be less than 100 psi (7 kg/cm 2 ).
VALVE CLEARANCE
Note. All models are equipped with hydraulic valve lifters; valve adjustment is not required. If valves are noisy or incorrect clearance is suspected, worn components are indicated. Check collapsed valve lifter clearance. See appropriate article in ENGINES.
HIGH TENSION WIRE RESISTANCE
On all models, high tension wire resistance should be no more than 7000 ohms per foot.
SPARK PLUGS
Note. See vehicle underhood emissions information decal for spark plug gap specification.
Note. If reusing originally installed spark plugs, reinstall them in original position. Some cylinders use platinum ground electrodes and some cylinders use platinum positive electrodes. Replacement platinum spark plugs are double platinum electrode spark plugs and are used for all cylinders.

IGNITION TIMING
Note. On all models with distributorless electronic ignition, manufacturer does not recommend checking ignition timing, as faulty readings are common and timing is not adjustable.
| Application | Degrees BTDC |
|---|
| Except Villager | 8-12 |
| Villager | 13-17 |
FUEL PUMP
Note. Fuel pump performance is a measurement of fuel pressure and volume availability, not regulated fuel pressure.
IDLE MIXTURE
Note. Idle mixture is not adjustable. For additional information, see appropriate THEORY & OPERATION article.
Villager
- Ensure all vehicle accessories are off and front wheels are straight. Apply parking brake. Ensure transmission is in Neutral or Park. Connect scan tool to Data Link Connector (DLC) and start engine. Using scan tool, monitor ECT and RPM PIDs.
- Loosen cold idle adjust nut and turn cold idle adjust screw to align fast idle cam cold mark with cam follower lever roller while ECT PID reads 66-86°F (20-30°C). Tighten cold idle adjust nut.
- Loosen base idle adjust nut and turn base idle adjust screw to adjust idle speed while ECT PID reads 167-185°F (75-85°C) and RPM PID reads 650-750 RPM. Tighten base idle adjust nut. Turn air conditioning on. Place A/C control in MAX position and blower fan control in HI position. Make sure idle speed is more than 800 RPM.
THROTTLE POSITION SENSOR
Note. Throttle Position (TP) sensor is not serviceable. TP sensor may also be referred to as Accelerator Pedal (AP) sensor. If TP sensor service is required, see TEST DH in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
