Radiator Assembly

The cleaning process for vehicle radiator components starts with inspecting the fins for clogs before using water or steam cleaning tools to remove blockages followed by compressed air drying while keeping proper steam cleaner distance. A screwdriver or pliers can be used to restore bent fins before you should withhold water from contacting electronic parts.

Engine coolant draining is required before disconnecting the radiator reserve tank hose or pipe followed by draining the radiator hose inlet and outlet and No.2 and No.3 oil cooler outlet hoses when using Automatic Transmission. Unscrew the two bolts which secure the air cleaner inlet assembly. Start by disconnecting the 2 horn connectors and removable the hood lock release lever cover and extracting the bolt illustrated in the diagram before securing the radiator support using its 4 holding bolts. The following operation requires disconnecting the fan motor connector then removing the radiator from the body. The lower radiator support along with fan assembly with motor can be removed after disconnecting the 3 bolts. Secure the fan assembly with motor onto the radiator by using 3 bolts then apply a torque of 5.0 Nm (51 kgf-cm, 44 inch lbs.). After placing the radiator back in its original body position connect the fan motor connector. Install the upper radiator support through its 4 mounting bolts while torquing them to 14 Nm (142 kgf-cm, 10 ft. lbs.) before reattaching the 2 horn connectors. The air cleaner inlet assembly needs to be installed with 2 bolts following a torque setting of 5.0 Nm (51 kgf-cm, 44 inch lbs.). After adjusting the hood sub-assembly personnel need to add engine coolant and examine the engine for any indicated leakage.

Adjust the hood sub-assembly, add coolant, and check for any engine coolant leaks.

Assemble Special Service Tool: 09230-01010, 09231-14010, adjusting the stopper bolt to achieve dimension B of 8.4 mm (0.331 inch).

Ensure a torque of 5.0 Nm (51 kgf-cm, 44 inch lbs.).

Apply a torque of 14 Nm (142 kgf-cm, 10 ft. lbs.).

First, drain the engine coolant.

Wash them with water or a steam cleaner and dry with compressed air.

Assemble Special Service Tool: 09230-01010 (09231-01010, 09231-01030) by installing the claw to the overhaul handle and adjusting the stopper bolt to ensure dimension B is between 0.2 to 0.3 mm (0.008 to 0.012 inch) to prevent damage.

First, drain the engine coolant.

Attach the fan assembly to the radiator using 3 bolts, ensuring a torque of 5.0 Nm (51 kgf-cm, 44 in-lbf).

Begin with on-vehicle cleaning by inspecting the fins for blockage.
