  Q: How to remove and install the radiator assembly on Toyota Echo?

  A:

  You must start by draining the engine coolant before removing the engine under covers. Disconnect the electrical cooling fan connector as well as the horn connector and upper and lower radiator hoses and radiator reservoir hose. Additionally disconnect the 2 oil cooler hoses for automatic transmission vehicles. Start by removing 2 clips with the radiator cover then the 7 (without A/C) or 9 (with A/C) bolts on the upper radiator supports to extract the radiator assembly together with the 2 radiator support cushions and grommets. Remove the electric cooling fan attached to the radiator by uninstalling its 3 bolts. Installation requires screwing the 3 bolts onto the radiator fan and tightening the bolts to 7.5 Nm (80 kgf-cm, 66 inch lbs.). The 2 radiator support cushions and grommets must first be installed on the radiator before fitting the 2 grommets from the radiator to the body brackets and securing the upper radiator supports through the 7 (without A/C) or 9 (with A/C) bolts. The installation requires connections of the upper radiator hose along with the lower radiator hose and the radiator reservoir hose. In automatic transmission systems you need to link up both the oil cooler hoses to the corresponding oil cooler pipes. You should install the radiator cover by using two clips before reconnecting the horn connector along with the electric cooling fan connector. The final step includes installing the engine under covers while filling it with engine coolant followed by starting the engine to check for any coolant leakages.

  Q: How to service and repair a radiator on Toyota Echo?

  A:

  Initiating radiator service or repair demands first step removal of the drain plug together with its O-ring. Disengage the No. 3 radiator hose to remove both bolts while also extracting the water filter at the same time. Attach the claw of Special Service Tool: 09230-01010 to the overhaul handle and adjust the stopper bolts to maintain a dimension "B" range between 0.2 - 0.3 mm (0.008 - 0.012 inch) to avoid any damage from occurring. Caulk plate removal requires squeezing the handle to stop when it reaches the bolts through this same tool. First gently strike the radiator bracket with a soft-faced hammer to remove the tank and O-ring and secondly for automatic transmission you must separate the oil cooler from the lower tank after losing the two nuts and plate washers followed by discrimination of the oil cooler and two O-rings. The lock plate needs inspection for damage which requires correction to ensure normal fitment because radiator recaulking occurs only twice before the radiator requires replacement. To reinstall use new O-rings and connect the oil cooler to the lower tank while using two plate washers and nuts which should be torqued to 8.34 Nm (85 kgf-cm, 74 inch lbs.). Start by positioning a new O-ring correctly into the lock plate groove without any twisting motion followed by installation of the tank while ensuring the O-ring remains undamaged and subsequently tapping the lock plate gently with either a soft hammer to eliminate all gaps. Special Service Tool: 09230-01010 and 09231-14010 should be used to adjust the stopper bolt until dimension "B" measures 8.4 mm (0.331 inch). Apply the tool to the lock plate according to the order while minimizing staking near pipes and brackets and measure the height which should be between 7.40 - 7.80 mm (0.2913 - 0.3071 inch) potentially adjusting if the reading is incorrect. Fitting the water filter requires 7.5 Nm (76 kgf-cm, 66 inch lbs.) of torque on its two bolts; you should then reconnect the No. 3 radiator hose followed by installing a new O-ring on the drain plug before tightening it. Apply Special Service Tool: 09230-01010 and test under 177 kPa pressure (1.8 kgf/cm2, 26 psi) using the radiator cap tester, then soak the radiator in water to perform leak detection. Keep in mind that resin tank radiators may hold a trace of air which can clear with radiator water swishing.
