ASSEMBLY B Oil Filter 1. Remove all foreign material from the oil filter mounting surface. 2. Apply a small amount of clean engine oil to the rubber seal of the oil filter. 3. Install the oil filter and tighten it by hand until the rubber seal contacts the base. 4. Hand tightening type (Numbers printed on filter) Tighten the filter 314 of a turn by hand after it contacts the cylinder block. If tightening by hand is difficult, use the filter wrench. Example When the oil filter contacts the cylinder block at "l", turn it 314 of a turn further to "4". Filter wrench tightening type (No numbers printed on fil- ter) Tighten the filter 1 and 116 turns with the filter wrench af- ter it contacts the cylinder block. Right Engine Mount Install the right engine mount. Tightening torque: 37-53 N-m (3.7-5.5 kgf.m, 27-39 ft.lbf) Alternator Bracket Install the alternator bracket. Tightening torque: 64-49 N-m (6.5--9.1 kgf-m, 48-45 ft4bf) Alternator Install the alternator and hand tighten the mounting bolts. Gartner Banana

D OIL FILTER OIL FILTER REPLACEMENT 1. Remove the oil filter with a wrench. ii 2. Use a clean rag to wipe off the mounting surface on the engine. 3. Apply a small amount of clean engine oil to the rubber seal of the new filter. 4. Hand tightening type (Numbers printed on filter) Tighten the filter 314 of a turn by hand after it contacts the cylinder block Example: When the oil filter contacts the cylinder block at "l", turn it 314 of a turn further to "4". Filter wrench tightening type (No numbers printed on fil- ter) Tighten the filter 1 and 116 turns with the filter wrench af- ter it contacts the cylinder block. Gartner Banana

OIL PAN D RIGHT . . LEFT Removal Note Engine mount nut 1. Loosen the oil pan mounting bolts. 2. Remove the engine mounting nuts. 3. Lift the engine slightly with a hoist. Crossmember installation bolt and nut 1. Support the crossmember with a transmission jack. 2. Remove the crossmember installation bolts and nuts. 3. Separate the steering intermediate shaft from the pinion shaft. 4. Lower the crossmember until the clearance between the oil pan and the steering gear housing exceeds approx. 100mm (3.94 in). Oil pan 1. Remove the oil pan mounting bolts. Caution Pry tools can easily scratch the cylinder block and the oil pan contact surfaces. Prying off the oild pan can also easily bend the oil pan flange. Refer to the following instructions before remov- ing the oil pan. 2. Insert a screwdriver only at the points shown in the fig- ure. 3. Remove the oil pan. Oil baffle 1. Insert a screwdriver between the cylinder block and the oil baffle to separate them. 2. Remove the oil baffle. Installation Note Oil baffle 1. Remove all foreign material from the contact surfaces. 2. Apply a continuous bead of silicone sealant to the oil baffle along the inside of the bolt holes, and install within five minutes. Gartner Banana

ENGINE COOLANT ENGINE COOLANT PREPARATION SST INSPECTION 49 9200 145 Adapter set, radiator cap tester Warning Removing the radiator cap or the coolant drain plug while the engine is running, or when the engine and radiator are hot is dangerous. Scalding coolant and steam may shoot out and cause serious injury. It may 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, andremove it. For inspection of cooling system pressure Coolant Level (Engine Cold) 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. Add coolant if neces- sary. u Note The distance between the LOW and FULL marks on the coolant reservoir represents 4.5 L (4.8 US qt, 4.0 Imp qt). Coolant Quality 1. Verify that there is no buildup of rust or scale around the radiator cap or radiator filler neck. 2. Verify that coolant is free of oil. Replace the coolant if necessary. 49 9200 146 Adapter A (Part of 49 9200 145) Coolant Leakage 1. Connect a radiator tester (commercially available) and the SST to the radiator filler neck. 2. Apply 103 kPa (1.05 kgf/cm2, 14.9 psi} pressure to the system. 3. Verify that the pressure is held. If not, check for coolant leakage. For inspection of cooling system pressure / V Caution Apply more than 103 kPa (1.05 kgf/cm2, 14.9 psi) can damage the hoses, fittings, and other compo- nents, and cause leaks. Gartner Banana

ENGINE COOLANT COOLANT PROTECTION SPECIFIC GRAVITY COOLANT TEMPERATURE "C (OF) 45UOEX-00 Coolant Protection Caution The engine has aluminum parts that can be dam- aged by alcohol or methanol antifreeze. Do not use alcohol or methanol in the cooling system. Use only ethylene-glycol-based coolant. Use only soft (demineralized) water in the coolant mixture. Water that contains minerals will cut down on the coolant's effectiveness. 1. Measure the coolant temperature and specific gravity with a thermometer and a hydrometer. 2. Determine the coolant protection by referring to the graph shown. If the coolant protection is not proper, add water or cool- ant.

Scalding coolant and steam may shoot out and cause seri- ous injury. If may 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. Remove the radiator cap and loosen the drain plug. 2. Drain the coolant into a container. 3. Flush the cooling system with water until all traces of col- or are gone, then let the system drain completely. 4. Install the drain plug. 55 45 45 55 1.066 1.078 Gartner Banana
