Checking Timing An access plug is provided in the cam drive belt cover so that camshaft timing can be checked without removal of the cover or any other parts. 1. Remove the access plug from the cam drive belt cover. 2. Rotate the crankshaft so that the No. 1 piston is rising on compression stroke. 3. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TC mark on the belt cover. Always turn the engine in the direction of normal rotation (clockwise, as viewed from the front). Backward rotation may cause the timing belt to jump time, due to the arrangement of the belt tensioner. 4. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover. 5. Install the belt cover access plug. Adjusting Timing Belt SPECIAL SERVICE TOOL(S) REQUIRED Description Crankshaft Belt Tension Adjusting Tool T74P-6254-A 1. Remove the outer timing belt cover as outlined in this section. CAUTION: Attempting to adjust timing belt tension without loosening spring pivot bolt will break Crankshaft Belt Tension Adjusting Tool T74P-6254-A when relieving tension on the belt. 2. If belt timing or tension is incorrect, loosen timing belt spring pivot bolt. 3. Hold tensioner with Camshaft Belt Tension Adjusting Tool T74P-6254-A. 4. While holding tensioner, loosen adjusting bolt and gradually release spring tension. Loosening Timing Belt Tensioner, 2.3L Tool Number 8 — 5. Using adjusting tool, pry tensioner away from belt. While holding, tighten adjusting bolt. There should be no tension on belt. Camshaft Timing Belt, 2.3L I-4 Timing Mark on Camshaft Sprocket Remove the bolts holding the crankshaft position sensor in place and pull the sensor assembly free of the dowel pin. 7. Remove the crankshaft pulley , crankshaft pulley hub and timing belt guide. 8. Remove the drive belt and inspect it for wear or damage. If the belt is damaged, replace it. 9. Remove one spark plug from each cylinder. 10. If not done: a. Loosen tensioner adjusting bolt. b. Using Camshaft Belt Tension Adjusting Tool T74P-6254-A, pry tensioner clockwise against spring tension as far as possible. c. Tighten adjusting bolt to hold tensioner in released position. 11. Align crankshaft so number one piston is at TDC (top dead center) as indicated by timing mark. 12. Line up camshaft sprocket timing mark with inner timing belt cover timing mark and key is pointing down.

1. General note. CAUTION: In MJ ’96 the camshaft timing belt was revised. Coolant pumps and timing belt tensioners with different idler pulleys are fitted in production. In service there are now only coolant pumps with two edges on the idler pulley available. It should be noted that when renewing the timing belt tensioner, a tensioner without an edge must not be fitted in conjunction with a coolant pump without edges. Converting a mechanical timing belt tensioner to an automatic timing belt tensioner is NOT permissible. In addition, since MY ’96 PTFE oil seals have been fitted at the front and rear of the crankshaft instead of the familiar Viton oil seals. CAUTION: Since 08.98 (build code WP), a revised oil pump has been fitted in conjunction with a revised oil pressure switch (green cover), and 5W 30 engine oil has been used. It should be noted that up to and including 07.98 (build code WM), an oil pressure switch with a black cover was fitted, and 10W-40 engine oil was used. Note: Installation position of the timing belt tensioner spring and the fuel-injection pump spring. DO NOT mix up the springs. 2. Detach the exhaust gas recirculation valve (EGR valve). 1 2 Disconnect the hose. Unscrew the bolts. 3. Detach the exhaust manifold. Mount the engine on an assembly stand. l Fit the mounting bracket. l Mount the engine on the assembly stand. Drain the engine oil. Detach the engine mounting. Note: Watch out for escaping oil. 7. Detach the oil pump with the oil filter.

NOTE: Ford does not provide camshaft gear timing marks, or information to perform timing belt service without the special tools shown in this procedure. 1. Grasp the spark plug boot firmly and with a twisting pulling motion, disconnect the spark plug wires from the spark plugs. 2. NOTE: If an original spark plug is reused, install it in the cylinder from which it was removed. New spark plugs can be used in any cylinder. NOTE: Use compressed air to remove any foreign material from the spark plug well before removing the spark plugs. Remove the spark plugs. 3. Remove the valve cover. 4. Disconnect the heated oxygen sensor (HO2S) electrical connector. 5. Remove the timing belt covers. 6. Remove the catalytic converter. 7. NOTE: Cylinder No. 1 is at top dead center (TDC) when the keyway is in the 12 o’clock position. Position cylinder No. 1 just prior to TDC. 8. Remove the stud bolt. Install the timing peg. 10. Rotate the crankshaft clockwise against the timing peg. 11. CAUTION: If the crankshaft timing belt is to be reused, mark the direction of the camshaft timing belt to the rotation of the camshaft prior to removal, or premature wear or failure may occur. Relieve the tension on the timing belt tensioner pulley. Loosen the tensioner pulley bolt. Release the tension on the timing belt by disconnecting the tensioner tab from the timing cover back plate.
