2001 Toyota Sienna Parts Questions & Experts Answers

• Q: How to service and repair the radiator on 2001 Toyota Sienna?

  A: The first step when repairing or servicing the radiator requires draining all engine coolant. The relay block for the daytime running light system should be disconnected from the battery hold-down clamp during removal operations in Canada. Disconnection of these items must commence with the No.1 electric cooling fan connector followed by the No.2 electric cooling fan connector then by the upper radiator hose from the radiator and the lower radiator hose from the water inlet pipe. Complete the disconnection with the two oil cooler hoses from the oil cooler pipes. Avoid damage to the radiator by lifting it out after removing its 2 bolts, 2 upper radiator supports, and ensuring all bolts reach 13 Nm (130 kgf-cm, 9 ft. lbs.). You should detach the lower radiator hose and the 2 oil cooler hoses from the radiator device. The installation of the No.1 electric cooling fan requires users to remove its 2 bolts along with the fan using a torque of 5.0 Nm using a 50 kgf-cm tip or 44 inch lbs. torque wrench. Users should perform this process again on the No.2 electric cooling fan. The installation process requires steps that reverse the sequence of removal.
