WYMIANA USZCZELKI GŁOWICY

1. Clean all surfaces of cylinder block and cylinder heads.

2. Clean cylinder block front and rear gasket surfaces using a suitable solvent.

CAUTION: The head gaskets (1) are interchangeable between left and right sides. They are marked “UP” to indicate direction to face up.






NOTE: Rotate crankshaft 45°, so that all pistons are ½ the way down the cylinder bore to avoid piston to valve contact.

3. Position new cylinder head gaskets (5) onto the cylinder block.

4. Position cylinder heads (4) in place.




5. Install head bolts.

6. Tighten the cylinder head bolts in four steps using the sequence shown:

  1. Step 1 - Tighten bolts 1-10 to 34 N·m (25 ft. lbs.) and bolts 11-15 to 20 N·m (15 ft. lbs.) in the sequence shown.
  2. Step 2 - Tighten bolts 1-1 0 to 54 N·m (40 ft. lbs.) and verify bolts 11-15 are 20 N·m (15 ft. lbs.) in the sequence shown.
  3. Step 3 - Rotate bolts 1-10 an additional 90 degrees in the sequence shown.
  4. Step 4 - Tighten bolts 11-15 to 34 N·m (25 ft. lbs.) in the sequence shown.

CAUTION: Pushrods and rocker arm assemblies must be installed in their original locations or engine damage could result.

7. Install Pushrod retainer  (1) on cylinder head.

8. Install intake pushrods in their original position and snap push rods into Pushrod Retainer (1).

9. Install intake rocker shaft and remove Pushrod Retainer (1).

10. Install exhaust pushrods and rocker shaft.

11. Install the intake manifold and throttle body assembly 

12. Install the spark plugs.

13. Connect the heater hoses.

14. Install the fuel supply line.

15. Install the power steering pump.

16. Install the accessory drive belt 




17. Install cylinder head covers (1) 




18. Install the ignition coils (1)




19. Connect the ignition coil electrical connectors (1) and injector electrical connectors.




20. Connect the evaporation control system.

21. Install the air cleaner housing and connect to throttle body.

22. Connect make-up air hose (1), and vacuum lines.

23. Connect intake air temperature sensor (4) electrical connector.




24. Fill cooling system 

25. Connect the negative cable to the battery (1).



26. Install engine covers (1).

27. Start engine check for leaks.
