Removal

Engine removal is not required for this procedure.

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.

5. Remove the under covers (A).

Tightening torque :
9.8 - 11.8N.m (1.0 - 1.2kgf.m, 7.2 - 8.7lb-ft)
