Part 1 of 2

Removal

CAUTION:
- Use fender covers to avoid damaging painted surfaces.
- To avoid damaging the cylinder head, wait until the engine coolant temperature drops below normal temperature before removing it.
- When handling a metal gasket, take care not to fold the gasket or damage the contact surface of the gasket.
- To avoid damage, unplug the wiring connectors carefully while holding the connector portion.

NOTE:
Mark all wiring and hoses to avoid misconnection.

WARNING:
The hybrid system uses DC 270V high voltage. So, be sure to follow safety instructions below. Otherwise, there may be a serious injury or electrocution .

1. Shut off the High Voltage circuit .
2. Remove the engine cover.
3. Remove the air duct and the air cleaner assembly.
4. Remove the under covers.
5. Remove the RH front wheel.
6. Loosen the drain plug, and drain the engine coolant. Remove the radiator cap to help drain the coolant faster.
7. Disconnect the radiator upper hose and lower hose.
8. Disconnect the wiring connectors and harness clamps, and remove the wiring and protectors from the cylinder head and intake manifold.

16. Remove the camshaft.
(1) Remove the front camshaft bearing cap (A) with the upper bearing (B).




(2) Remove the camshaft bearing cap (A) in the sequence shown.




(3) Remove the camshafts (A).




(4) Remove the exhaust camshaft lower bearing (A).




17. Remove the intake OCV (Oil control valve) (A) using a torx wrench.




18. Remove the exhaust OCV (Oil control valve) (A) using a torx wrench.




19. Remove the intake CMPS (Camshaft position sensor) (A).




20. Remove the exhaust CMPS (Camshaft position sensor) (A) after removing the engine hanger and cam position sensor cover (B).




21. Remove the cylinder head.
(1) Using triple square wrench, uniformly loosen and remove the 10 cylinder head bolts, in several passes, in the sequence shown. Remove the 10 cylinder head bolts and plate washers.





CAUTION:
Head warpage or cracking could result from removing bolts in an incorrect order.

(2) Lift the cylinder head (A) from the dowels on the cylinder block and place the cylinder head on wooden blocks on a bench.

CAUTION:
Be careful not to damage the contact surfaces of the cylinder head and cylinder block.

(3) Remove the cylinder head gasket (B).
