Maintenance Item Specific Work Required
ENGINE
Engine valve clearance Measure clearance
Drive beltsInspect for wear, cracks and fraying, and check tension.
Replace drive belt.
Engine timing belt Replace engine timing belt.
Engine oil Replace engine oil and inspect for leakage.
Oil filter Replace oil filter and inspect for leakage.
COOLING SYSTEM
Cooling system
(including coolant level adjustment)Check coolant level and quality, and inspect for leakage.
Engine coolant Replace coolant.
FUEL SYSTEM
Air cleaner elementInspect for dirt, oil and damage.
Clean air cleaner element (by blowing air).
Replace air cleaner element.
Fuel filter Replace fuel filter.
Fuel lines and hoses Inspect for cracks, leakage and loose connection.
Fuel injection system (for MZR-CD (RF Turbo)) Update to injection amount correction with WDS. (see W/M)
IGNITION SYSTEM (FOR GASOLINE)
Spark plugsInspect for wear, damage, carbon, high-tension lead condition and measure
plug gap.
Replace spark plugs.
EMISSION CONTROL SYSTEM
Evaporative system (for gasoline)Check system operation (see W/M), vapor lines, vacuum fitting hoses and
connection.
E.G.R. system (MZR-CR (RF Turbo))Check system operation (see W/M), vacuum fitting hoses and connection.
Update to MAF correction for E.G.R control with WDS. (see W/M)
ELECTRICAL SYSTEM
Battery electrolyte level and specific gravity Check level and specific gravity.
CHASSIS AND BODY
Brake fluidCheck fluid level and inspect for leakage.
Replace brake fluid.
Brake lines, hoses and connectionsInspect for cracks, damage, chafing, corrosion, scars, swelling and fluid
leakage.
Parking brake Check lever stroke.
Power brake unit and hosesCheck vacuum lines, connections and check valve for improper attachment,
air tightness, cracks chafing and deterioration.
Disc brakesTest for judder and noise. Inspect caliper for correct operation and fluid
leakage, brake pads for wear. Check disc plate condition and thickness.
Power steering fluid and linesCheck fluid level and lines for improper attachment, leakage, cracks,
damage, loose connections, chafing and deterioration.
Power steering fluid Check fluid level.
Power steering system and hosesCheck lines for improper attachment, leakage, cracks, damage, loose
connections, chafing and deterioration.
Steering operation and gear housingCheck that the steering wheel has the specified play. Be sure to check for
changes, such as excessive play, hard steering or strange noises.
Check gear housing and boots for looseness, damage and grease/gear oil
leakage.
Steering linkages tie rod ends and armsCheck ball joint, dust cover and other components for looseness, wear,
damage and grease leakage.
Front and rear suspension and ball joints Inspect for grease leakage, cracks, damage and looseness.
Manual transmission/transaxle oilCheck oil level and inspect for leakage.
Replace manual transmission/transaxle oil.
Automatic transmission/transaxle fluid level Check fluid level.

K2–74
AUTOMATIC TRANSAXLE
Evaluation of line pressure test
Stall Speed Test
1. Perform mechanical system test preparation. (See K2–72 Mechanical System Test Preparation.)
2. Connect a tachometer.
3. Start the engine.
4. Shift the selector lever to D range.
Caution
•Do not maintain WOT in any gear range for more than 5 seconds or transaxle damage will occur.
•If engine speed recorded by the tachometer exceeds maximum specified rpm, release the
accelerator pedal immediately. Clutch or band slippage is indicator.
5. Firmly depress the brake pedal with the left foot, and gently depress the accelerator pedal to the floor (WOT)
with the right.
6. When the engine speed no longer increases, quickly read the engine speed and release the accelerator pedal.
7. Shift the selector the to N position and let the engine idle for 1 minute or more to cool the ATF.
8. Perform stall tests for the remaining ranges and position in the same manner.
•R position
•Mrange (1GR, 2GR)
Engine stall speed
ATF temperature : 60—70 °C {140—158 °F}
Turn off all electrical loads
2,200—2,600 rpm
9. Turn off the engine.
