   When removing and installing the oil temperature sensor, use a deep socket as shown in the illustration below. 3/8 in. (24 mm) thin-wall deep socket with a length of less than 75 mm. [Oil Temperature Sensor Removal Tool Arrangement] 24 mm deep socket1/2 in. to 3/8 in. adapter (only when using a 1/2 in. deep socket)3/8 in. universal joint3/8 in. extensionSocket wrench [Tool Installation Sequence] Insert the 24 mm (0.94 in.) socket (A) onto the oil temperature sensor. After connecting the other tools as shown in the illustration above, insert the tools (A) into the socket.

Installation

Install the component with the specified torque. Be careful not to drop the component, as internal damage may occur. If dropped, inspect it before installation.

Apply sealant (LOCTITE FED546 or equivalent) to the sensor.

Insert the sensor into the mounting hole, taking care not to damage it during installation.

1. To install, reverse the removal procedure. CVVT oil temperature sensor installation: 14.7 - 22 N·m
