2004 Kia Sorento EX Timing Belt Removal

This application is an interference engine. Do not rotate camshaft or crankshaft when timing belt is removed, or engine damage may occur. 1. Disconnect negative battery cable. Remove engine cover. Using 16-mm spanner wrench, rotate serpentine belt tension arm clockwise about 14 degrees to relieve belt tension. Remove serpentine drive belt. Remove power steering pump pulley, idler pulley, tensioner pulley and crankshaft pulley. Remove upper and lower timing belt covers. See Fig. 1 or Fig. 2 . Rotate crankshaft clockwise and align timing mark to set No. 1 cylinder to TDC on compression stroke. 2. Ensure timing marks of camshaft sprocket and cylinder head cover are matching. See Fig. 5 . On Sedona, support engine with jack and remove engine mounting insulator. On all models, remove auto tensioner. If timing belt is to be reused, mark rotational direction on belt for reinstallation reference. CAUTION: If either camshaft is set at TDC for cylinder No. 1 at the compression stroke and the corresponding camshaft on the same cylinder head is rotated 180 degrees while the timing belt is removed, intake and exhaust valves may contact each other. 3. Unbolt timing belt tensioner pulley, and remove timing belt.
Inspection Inspect timing belt for wear on edges of drive teeth. Inspect the belt for signs of oil contamination, cracks, separation, worn or missing teeth, or hardened Black surface. Replace belt if worn, damaged or contaminated. Inspect belt tensioner pulley for smooth rotation. Replace if defective. Check timing belt auto tensioner for leaks. Replace if necessary.
Installation 1. Install timing belt idler pulley to engine support lower bracket. Install tensioner arm, shaft and washer to cylinder block. Tighten tensioner arm bolt to specification. See TORQUE SPECIFICATIONS . CAUTION: Use care to avoid bending crankshaft sensing blade of crank angle sensor. 2. Install crankshaft sprocket and align timing mark. See Fig. 4 . Install camshaft sprocket and adjust installation positions as shown. See Fig. 5 and Fig. 6 . Install auto tensioner to oil pump case. Ensure that...
