ENGINE TUNE-UP ENGINE TUNE-UP PREPARATION SST I 49 9200 020 Tension gauge, V-ribbed belt For inspection of ignition timing and idle speed For inspection of drive belt tension ENGINE OIL 49 801 9 9AO System selector Warning Continuous exposure with USED engine oil has caused skin cancer in laboratory mice. Protect your skin by washing with soap and water im- mediately after this work. Inspection 1. Be sure the vehicle is on level ground. 2. Warm up the engine to normal operating temperature and stop it. 3. Wait for five minutes. 4. Remove the dipstick and check the oil level and condi- tion. 5. Add or replace oil if necessary. Note The distance between the L and F marks on the dip- stick represents 0.8 L (0.85 US qt, 0.70 Imp qt}. ENGINE COOLANT Inspection Coolant level (engine cold) Warning Removing the radiator cap or the coolant filler cap while the engine is running, or when the engine and radiator are hot is dangerous. Scalding cool- ant and steam can shoot out and cause serious in- jury. It can also damage the engine and cooling system. Turn off the engine and wait until it is cool. Even then, be very careful when removing the cap. Wrap a thick cloth around it and slowly turn it counterclockwise to the first stop. Step back while the pressure escapes. When you're sure all the pressure is gone, press down on the cap-still using a cloth - turn it, and remove it. 1. Verify that the coolant level is near the radiator filler neck. 2. Verify that the coolant level in the coolant reservoir is be- tween the FULL and LOW marks. 3. Add coolant if necessary. Gartner Banana

ENGINE TUNE-UP HLA TROUBLESHOOTING GUIDE Problem 1. Noise when engine is started immediately af- ter oil is changed 2. Noise when engine is started after setting approx. one day 3. Noise when engine is started after cranking for 3 seconds or more 4. Noise when engine is started after new HLA is installed 5. Noise continues more than 10 minutes 5. Noise occurs during idle after high speed run- ning Possible Cause Oil leakage in oil passage Oil leakage in HLA Faulty HLA Action Run engine 2000-3000 rpm. If noise stops after 2 second-10 minutes(') HLA is normal. If not, replace HLA. Time required for engine oil to circulate withir engine, includes tolerance for engine oi condition and ambient temperature. Insufficient oil pressure (Refer to page 8-53) Press down HLA by hand. If it does not move, HLA is normal. If it moves, replace HLA. Check oil pressure. If lower than specification, check for cause. Oil pressure; 295-392 kPa I3.0-4.0 kgf/cm2, 43-56 psil-3000 rpm Deteriorated oil Check oil quality. If deteriorated, replace with specified type and amount of oil. Incorrect oil amount IGNITION TIMING, IDLE SPEED Preparation 1. Check the condition of the engine (spark plugs, leaks in hoses, etc.). 2. Make sure all accessories are OFF. 3. Warm up the engine to normal operating temperature. 4. Connect a timing light and a tachometer to the data link connector terminal IG-. When using an externally pow- ered timing light and/or tachometer, connect it to the power connector (Blue: 1 -pin). Measure valve clearance. If more than Omm {0 in}, replace HLA. Check oil level. Drain or add oil as necessary. Caution Grounding the power connector terminal (Blue: 1-pin) will burn out the 20A wiper fuse. 5. Make sure coolant fan does not operate. Gartner Banana
