• Q: How to remove and install the radiator on 2003 Toyota Celica?

  A: The radiator removal process requires a sequence of draining engine coolant from the system followed by the upper front fender apron seal and upper radiator support seal removal. The next sequence involves disconnecting 3 radiator reservoir hoses followed by removing the bolt to take out bumper cover, air cleaner and engine coolant reservoir. The radiator assembly removal starts with disconnecting the No. 1 and No. 2 electric cooling fan connectors followed by upper and lower radiator hoses removal and disconnection of the 2 A/T oil cooler hoses. Begin by removing three bolts securing the hood lock followed by two bolts and the center brace then you must disconnect two bolts, two nuts, two condenser upper supports, then separate the bolt needed to release the cruise control actuator if the system is present. The installation begins by removing two radiator upper support bolts and radiator upper support then moves to the upper radiator support bushings followed by installing the radiator assembly together with its two lower radiator support bushings. The electric cooling fan from the radiator can be taken away after removing the 2 bolts which hold the cooling fan assembly in place. During installation begin by attaching the electric cooling fan to the radiator through its 2 bolts then torque them to 5.0 Nm (51 kgf-cm, 44 inch lbs.). The installation process starts with 2 lower radiator support bushings before adding the radiator assembly and then continuing with 2 upper radiator support bushings and the radiator upper support bolted with 2 bolts. A cruise control system requires installation of the cruise control actuator first using 3 bolts followed by installation of the 2 condenser upper supports with their respective 2 bolts and nuts then the center brace with its 2 bolts and the hood lock with its 3 bolts. The procedure requires connecting the A/T oil cooler hoses together with both lower and upper radiator hoses and attaching the No. 1 and No. 2 electric cooling fan connectors. The installation of the engine coolant reservoir requires a 5.0 Nm torque on the bolt and subsequent connection of its 3 radiator reservoir hoses. To finish the procedure install the air cleaner then attach the bumper cover before filling the engine with coolant and adding both upper front fender apron and upper radiator support seals followed by engine start-up to check for any coolant leaks.
