Valves should be adjusted only when the cylinder head temperature is less than 100° (38° . F C) After adjusting, retorque the crankshaft pulley bolt to 245 N.m (25.0 kgf.m, 181 lbf.ft) . 1. Remove the cylinder head cover. 2. Set No.1 piston at TDC . “UP” mark on the camshaft pulley should be at top, and TDC grooves on the camshaft pulley should align with cylinder head surface. 3. Adjust valves on No.1 cylinder. Intake: 0.26 mm ±0.02 mm (0.010 in) ± (0.0008 in) Exhaust: 0.30 mm ±0.02 mm (0.012 in) ±(0.0008 in) 4. Loosen the locknut, and turn the adjusting screw until the feeler gauge slides back and forth with a slight amount of drag. 5. Tighten the locknut and check clearance again. Repeat adjustment if necessary. 6. Rotate crankshaft 180° counterclockwise (Camshaft pulley turns 90° . The ) “UP” mark should be on the exhaust side. Adjust valves on No.3 cylinder. 7. Rotate crankshaft 180° counterclockwise to bring No.4 piston to TDC . Both TDC grooves are once again visible. Adjust valves on No.4 cylinder.
Remove belt tension adjuster. 9) Remove camshaft position sensor. 10) Remove left side camshaft pulley by using ST. ST 499207100 CAMSHAFT SPROCKET WRENCH 11) Remove left side rear timing belt cover. 12) Remove tensioner bracket. 13) Disconnect heater hose from engine coolant pump. 14) Remove engine coolant pump. B: INSPECTION 1) Check engine coolant pump bearing for smooth rotation. 2) Check engine coolant pump pulley for abnormalities. 3) Using a dial gauge, measure impeller runout in thrust direction while rotating the pulley. “Thrust” runout limit: 0.5 mm (0.020 inch) 4) Check clearance between impeller and pump case. Clearance between impeller and pump case: Standard: 0.5 – 0.7 mm (0.020 – 0.028 inch)
