Removal Procedure

    Notice: When adding coolant, use DEX-COOL® coolant. If silicated coolant is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner-at 50 000 km (30,000 mi) or 24 months.

  1. Disconnect the negative battery cable. Refer to

    Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

    in General Information.
  2. Drain the cooling system. Recover the coolant. Refer to Draining and Filling Cooling System .
  3. Remove the air intake duct assembly. Refer to Air Intake Duct Replacement in Engine Controls.
  4. Disconnect the upper transaxle oil cooler line from the radiator (Automatic Transmission).

  5. Object Number: 12064  Size: SH
  6. Disconnect the radiator inlet hose and the clamp from the radiator.
  7. Raise the vehicle. Refer to General Information.
  8. Disconnect the lower transaxle oil cooler line from the radiator.
  9. Remove the cooling fan. Refer to Electric Cooling Fan .
  10. 8.1. Disconnect the cooling fan electrical connector.
    8.2. Remove the fan retaining bolt.

Installation Procedure


    Object Number: 25877  Size: SH
  1. Install the radiator
  2. Install the radiator mounts and the bolts.
  3. Tighten
    Tighten the bolts to 10 N·m (89 lb in).

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
