How to install the radiator assembly and its components on Toyota 4Runner?

When installing the radiator component use 4 bolts to fasten the radiator support at the radiator service holes while reaching 18 Nm (184 kgf-cm, 13 ft-lbf) torques. Now attach the fan shroud tabs which fit into their respective openings by using two bolts tightened to 5.0 Nm (51 kgf-cm, 44 in-lbf). The radiator reserve tank assembly installation requires 3 bolts which should be secured to 5.0 Nm (51 kgf-cm, 44 in-lbf) torque before connecting the reserve tank hose to the radiator. The last step includes adding engine coolant before conducting a leak inspection.

How to remove and replace the radiator on Toyota 4Runner?

Beginning radiator replacement requires draining engine coolant before starting the work. Separate the 11 clips along with the radiator support upper before proceeding. You should begin by disconnecting the reserve tank hose from the radiator followed by radiator hose No. 1 and oil cooler inlet hose and oil cooler outlet hose then radiator hose No. 2. When completed separate the fan shroud through the removal of the 3 bolts so you can place it at an appropriate location in the engine room. You need to uninstall the radiator assembly after detaching its 4 bolts. Initial actions begin with the removal of radiator support No. 1 and radiator support No. 2 after unfastening 1 and 3 bolts from each part. End the process by taking out the 4 radiator support No. 1 bush.
