Refer to GI-10, "Components" for symbol marks in the figure.
NOTE:
The figure illustrates VQ35DE as an example. Each part form of VQ23DE is different from VQ35DE for differ-
ence of port diameter and so forth. Only portions which structures (components) differ are illustrated.
REMOVAL
WARNING:
To avoid the danger of being scalded, do not drain engine coolant when engine is hot.
NOTE:
Show VQ35DE as an example unless the figure includes specification.
1. Remove engine cover.
CAUTION:
Be careful not to damage or scratch engine cover.
2. Remove air cleaner case (upper) with mass air flow sensor and air duct assembly. Refer to EM-131, "
AIR
CLEANER AND AIR DUCT" .
3. Drain engine coolant, or when water hoses are disconnected, attach plug to prevent engine coolant leak-
age. Refer to CO-34, "
Changing Engine Coolant" .
CAUTION:
Perform this step when engine is cold.
4. Remove electric throttle control actuator as follows:
a. Disconnect harness connector.
b. Loosen mounting bolts in the reverse order as shown in the fig-
ure.
CAUTION:

Handle carefully to avoid any shock to electric throttle
control actuator.

Do not disassemble.
5. Disconnect water hoses from intake manifold collector (upper).
