For 1990-2009 cars

### 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.

2. Raise the vehicle. Support the vehicle with safety stands. Refer to General Vehicle Lifting and Jacking in General Information.
3. Remove the lower air deflector.
4. Drain the coolant. Refer to Cooling System Draining and Filling .
5. Lower the vehicle.
6. Remove the radiator inlet hose (1) with the clamps, and the outlet hose (2) with the clamps, from the radiator and the engine (L36 and L67).

### Installation Procedure

1. Install the radiator inlet hose (1) with the clamps, and the outlet hose (2) with the clamps, to the engine and the radiator (L36 and L67).
2. Raise the vehicle. Support the vehicle with safety stands. Refer to General Vehicle Lifting and Jacking in General Information.
3. Install the lower air deflector.
4. Lower the vehicle.
5. Refill the coolant. Refer to Cooling System Draining and Filling .
6. Connect the negative battery cable.

Tighten
Tighten the negative battery cable bolt to 15 N·m (11 lb ft).

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.

7. Start the engine. After the engine reaches normal operating temperature, check for coolant leaks.
