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

  A: Service and repair of the radiator requires two steps starting with refrigerant discharge from the refrigeration system followed by evacuation of air and charging system with exactly 500 plus or minus 50 g (17.64 plus or minus 1.76 oz.) of refrigerant before checking for any leaks. The radiator requires its engine coolant to be drained but you should leave some coolant inside. First disconnect the electric cooling fan assembly and front bumper before separating the radiator reservoir hose. Secure the discharge and liquid tube connection by disconnecting the 2 bolts which must be torqued to 5.4 Nm (55 kgf-cm, 48 inch lbs.). Immediately apply caps to the open fittings to stop moisture and dirt entry into the system. O-rings need compressor oil lubrication before installation onto tubes whereafter the removal of the bolt releases the liquid tube bracket. Begin by detaching the radiator upper supports using the two bolts then push the radiator & condenser module toward the engine as you rise it to eliminate the lower radiator support until the complete removal is done. The installation process follows exactly the reverse steps of removal procedures.
