Removal & Installation

To remove:

1.6L (B16A2) Engines

  1. Disconnect the negative battery cable.
  2. Raise and safely support the vehicle.
  3. Drain the engine oil.
  4. Label and disconnect the ignition wires.
  5. Set the No. 1 cylinder to Top Dead Center (TDC) for the compression stroke. The mark on the crankshaft pulley should align with the index mark on the timing cover. Mark the direction of the timing belt rotation if it is to be reinstalled.
  6. Release the tensions of the accessory drive belts and slip them off their pulleys. Remove the crankshaft pulley.
  7. Remove the valve cover and the upper and lower timing belt covers. Cover the rocker arm and shaft assemblies with a towel or sheet of plastic to keep out dirt and foreign objects.
  8. Release the timing belt tension. Then, remove the timing belt.

  10. Remove the crankshaft sprocket.
  11. Remove the oil pan and oil screen.
  12. Unbolt, then remove the oil pump assembly.

To install:

Replace the rotors if they are worn or damaged. Use new O-rings when assembling and installing the oil pump.

  1. Install the rotors back into their original positions. Be sure they rotate without binding. Pack the rotor cavity with petroleum jelly to prevent oil starvation damage when the engine is initially started.
  2. Assemble the oil pump and tighten the rotor cover bolts to 5 ft. lbs. (7 Nm).
  3. Be sure all gasket mating surfaces are clean prior to installation. Replace the crankshaft oil seal prior to installing the oil pump.
  4. Install a new crankshaft oil seal into the oil pump housing.
  5. Apply liquid gasket to the oil pump mating surface of the cylinder block. Apply a light coat of oil to the crankshaft seal lip. Install a new oil passage O-ring on the cylinder block, then install the oil pump. Apply liquid gasket to the threads of the oil pump mounting bolts and tighten them the 6mm bolts to 8 ft. lbs. (11 Nm).
  6. Tighten the 8mm bolts to 17 ft. lbs. (24 Nm).
  7. Lightly lubricate the relief valve piston and spring, then install them. Install the sealing bolt with a new crush washer and tighten it to 29 ft. lbs. (39 Nm).
  8. Install the oil screen.
  9. Install the oil pan. Wait for the sealant to cure before refilling the engine with oil.
  10. Install the CKF sensor. Tighten the sensor mounting bolts to 8 ft. lbs. (11 Nm).
  11. Install the crankshaft sprocket. The concave surface of the spacer faces out.
  12. Install and tension the timing belt. Tighten the tensioner adjusting bolt to 40 ft. lbs. (55 Nm).
  13. Install and reconnect the CKF sensor. Tighten the sensor mounting bolt to 9 ft. lbs. (12 Nm).
  14. Install the upper and lower timing belt covers. Install the valve cover. Be sure all rubber seals and gaskets are properly seated.
  15. Tighten the crankshaft pulley bolt to 130 ft. lbs. (180 Nm).
  16. Install a new oil filter. Refill the engine with fresh oil.
  17. Install and adjust the accessory drive belts.
