WARNING: This page does not describe the selected car, but rather 20 other vehicles, including the 2003 Mazda Protege5, 2003 Mazda Protege, 2002 Mazda Protege5, 2002 Mazda Protege, and 2002 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect negative battery cable. Remove Crankshaft Position (CKP) and Camshaft Position (CMP) sensors from front of engine (if equipped). See Fig 1. Remove spark plugs.
- Remove accessory drive belts. Leaving hoses attached, remove power steering pump and position aside. Remove the water pump pulley. See Fig 2. Rotate crankshaft so No. 1 cylinder is on TDC of compression stroke.
- Using Coupling Flange Holder (49 S120 710) and Adapter (49 E011 1A1), or equivalent, hold the crankshaft and remove crankshaft pulley bolt. See Fig 3. Remove crankshaft pulley and guide plate (large washer).
- Loosen valve cover bolts in 2-3 steps in order shown. See Fig 4. Remove valve cover and gasket.
- Remove dipstick tube. Remove upper and lower timing belt covers. Support engine from above. Remove No. 3 engine mount at timing belt end of engine.
- If reusing timing belt, mark arrow on belt to indicate direction of rotation. Install crankshaft pulley bolt finger-tight to retain crankshaft sprocket. Rotate crankshaft clockwise (as viewed from timing belt end of engine) until cylinder No. 1 piston is at TDC of compression stroke and timing marks are aligned. See Fig 5.
- Turn tensioner clockwise using a Allen wrench to relieve spring tension, and then disconnect spring from the hook pin. See Fig 6. Remove timing belt. Remove crankshaft sprocket, tensioner and idler pulley (if necessary).
CAUTION:
On models with a crankshaft position sensor, rotor is on rear of crankshaft pulley. DO NOT damage rotor when removing crankshaft pulley.
