How to Check & Replace the Timing Belt on a 1994 - 2000 Acura Integra 4 Cyl 1.8L PFI DOHC 1.8L Engines
Replace the timing and balancer shaft belts at no more that 105,000 miles (168,000km). Acura also specifies that under extreme conditions the timing and balancer shaft belts should be replaced more frequently, at 60,000 miles (100,000 km). These abnormal conditions include very high temperatures over 110°F (43°C) or very low ambient temperatures of minus 20°F (-29°C).
Removal & Installation
1. Remove the negative battery cable.
2. Remove the splash shield from the wheel well.
3. Remove the power steering pump by loosening the adjusting bolts and removing the mounting bolts.
4. Loosen the adjusting and idler pulley bracket bolt on the (A/C) to free the belt.
5. Loosen the adjusting nut and then the mounting nuts to allow the alternator belt to be removed.
6. Remove the cruise control actuator if equipped.
7. Remove the side engine mount bolts and then mount.
8. Remove the valve cover.
9. Remove the crankshaft bolt.
Be careful when removing the crankshaft damper bolt. Excessive force may snap or strip the bolt.
10. The middle timing cover can be removed by unbolting the two fasteners.
11. Remove the lower timing belt cover.
12. The timing belt tensioner adjusting bolt must now be loosened no more than180°.
13. The tension on the belt can be released by pushing against it.
14. After the tension is released retighten the adjusting bolt.
15. Remove the timing belt from the pulleys.
If oil leakage is detected around the camshaft or crankshaft seals, replace them.
16. Remove the camshaft pulley(s) by removing the bolt(s) from the pulley(s).
17. The camshaft pulleys do not need to be match marked to the location of the camshafts. They are machined to only go on in one direction via the use of a woodruff key. It is a good idea to mark the pulleys left and right respectively.
18. Install the camshaft pulleys.
Clean the covers before installation. The smallest piece of dirt may cause premature belt failure.
19. Set the crankshaft and camshaft pulleys as in the illustration before installing the timing belt.
20. Set the crankshaft so that the No. 1 position is at top dead center (TDC). Position the groove on the teeth side of the belt to the pointer of the oil pump.
21. Install the timing belt, its components, and covers.
22. Align the TDC marks located on the intake and exhaust pulleys.
23. Install the belt in the following sequence:
A. Timing belt drive pulley.
B. Adjusting pulley.
C. Water pump pulley.
D. Exhaust camshaft pulley.
E. Intake camshaft pulley.
WARNING: Turning the crankshaft in the clockwise direction may cause the timing belt to not seat properly causing component damage.
24. Turn the crankshaft about four to six turns counterclockwise to ensure that the belt properly seats on the pulleys.
25. Set the number one piston at top dead center (TDC).
26. Loosen the adjusting bolt (180°only)
27. Rotate the crankshaft counterclockwise 3 teeth on the camshaft pulley, then tighten he adjusting bolt to 40 ft. lbs. (54 Nm).
28. Check that the crankshaft and camshaft pulleys are at TDC.
If the camshaft pulley is not positioned at TDC, remove the timing belt and repeat the above procedures.
29. Install the valve cover.
30. Install the engine mount(s).
31. If equipped, install the cruise control actuator.
Lubricate the crankshaft pulley bolt with engine oil.
32. Install the crankshaft damper and damper mounting bolt. Tighten the mounting bolt to 130 ft. lbs. (177 Nm).
33. Install the alternator, A/C, and power steering accessories.
34. Install the splash shield into the wheel well.
35. Connect the negative battery cable.
