cap tester (commercial service tool) and radiator cap tester adapter (commercial service tool).
REMOVAL
1. Remove following parts:

Front engine undercover (power tool)

Engine cover: Refer to EM-179, "INTAKE MANIFOLD" .

Engine room cover (RH and LH): Refer to EM-173, "ENGINE ROOM COVER" .

Air duct (inlet): Refer to EM-177, "AIR CLEANER AND AIR DUCT" .

Alternator, water pump and A/C compressor belt: Refer to EM-174, "DRIVE BELTS" .
2. Drain engine coolant from drain plugs on radiator and both side of cylinder block. Refer to CO-40, "
Chang-
ing Engine Coolant" and EM-253, "DISASSEMBLY" .
CAUTION:

Perform this step when engine is cold.
