1. Before checks, check that the engine oil, starter and battery are normal. Also, set the vehicle in the following condition: Engine coolant temperature: 80 - 95°C (176 - 203°F) Lights and all accessories: OFF Transaxle: Neutral (P range on vehicle with A/T) NOTE: On vehicles for Canada, the headlight, taillight, etc. remain lit even when the lighting switch is in "OFF" position but this is no problem for checks and adjustment.
2. Remove all of the ignition coils.
3. Remove the rocker cover.
4. Turn the crankshaft clockwise until the notch on the pulley is lined up with "T" mark on the timing indicator.
5. Move the rocker arms on the No.1 and No.4 cylinders up and down by hand to determine which cylinder has its piston at the top dead center on the compression stroke. If both intake and exhaust valve rocker arms have a valve lash, the piston in the cylinder corresponding to these rocker arms is at the top dead center on the compression stroke.
6. Valve clearance inspection and adjustment can be performed on rocker arms indicated by white arrow mark when the No.1 cylinder piston is at the top dead center on the compression stroke, and on rocker arms indicated by black arrow mark when the No.4 cylinder piston is at the top dead center on the compression stroke.
7. Measure the valve clearance. If the valve clearance is not as specified, loosen the rocker arm lock nut and adjust the clearance using a thickness gauge while turning the adjusting screw. Standard value (hot engine): Intake valve: 0.20 mm (0.008 inch) Exhaust valve: 0.30 mm (0.012 inch)

2. Check that the oil level is up to the lower edge of the filler plug hole.
3. Check that the oil is not noticeably dirty.
4. Tighten the filler plug to the specified torque. Tightening torque: 32 +/- 2 N. m (24 +/- 1 ft-lb)

Scheme 25

Scheme 26

1. Remove the filler plug.
2. Remove the drain plug and drain the oil.
3. Tighten the drain plug to the specified torque. Tightening torque: 32 +/- 2 N. m (24 +/- 1 ft-lb)
4. Fill with DiaQueen NEW MULTI GEAR OIL (GL-3) SAE 75W - 80 until the level comes to the lower portion of filler plug hole. Quantity: < F5M42 > 2.2 dm 3 (2.3 quarts) < F6MBA > 2.2 dm 3 (2.3 quarts)
5. Tighten the filler plug to the specified torque. Tightening torque: 32 +/- 2 N. m (24 +/- 1 ft-lb)

Scheme 27

Scheme 28

1. Drive the vehicle until the transmission fluid temperature rises to the normal operating temperature [70 - 80°C (158 - 176°F)]. NOTE: The transmission fluid temperature is measured with scan tool MB991958 (MUT-III sub assembly). NOTE: If it takes some amount of time until the transmission fluid reaches its normal operating temperature [70- 80°C (158- 176°F)], check the transmission fluid level by referring to the diagram at left.
2. Park the vehicle on a level surface.
3. Move the selector lever through all positions to fill the torque converter and the hydraulic circuits with fluid, and then move the selector lever to the "N" position.
4. After wiping off any dirt around the dipstick, remove the dipstick and check the condition of the transmission fluid. NOTE: If the transmission fluid smells as if it is burnt, it means that the transmission fluid has been contaminated by fine particles from the bushings and friction materials. Transaxle overhaul and cooler line flushing may be necessary.
5. Check transmission fluid level is at the "HOT" mark on the dipstick. If the transmission fluid level is less than this, add DIAMOND ATF SP III until the level reaches the "HOT" mark. NOTE: If the transmission fluid level is too low, the oil pump will draw in air along with the transmission fluid, which will cause to form bubbles. If the transmission fluid level is too high, rotating components inside the transaxle will churn the fluid and air into a foamy liquid. Both conditions (level too low or too high) will cause the hydraulic pressure to drop, which will result in late shifting and slipping of the clutches and brakes. NOTE: In either case, air bubbles can interfere with normal valve, clutch, and brake operation. Also, foaming can cause transmission fluid to escape from the transaxle vent where it may be mistaken for a leak.
6. Securely insert the dipstick. NOTE: The transmission fluid should always be replaced under the following conditions: When troubleshooting the transaxle. When overhauling the transaxle. When the transmission fluid is noticeably dirty or burnt (driving under severe conditions).
