Radiator Surge Tank L47

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. Disconnect the two inlet hoses and clamps from the surge tank.
3. Remove the air cleaner outlet duct assembly.
4. Drain the coolant from the surge tank. Refer to Cooling System Draining and Filling .



5. Disconnect the outlet hose and clamp from the surge tank.



6. Disconnect the coolant level sensor electrical connector from the bottom of the surge tank.



7. Remove the surge tank nut from the wheelhouse panel. Remove the two bolts and the nuts securing the surge tank to the fender rail.
8. Remove the surge tank.

1. Install the surge tank in position in the vehicle.
2. Install the surge tank nut to the wheelhouse. Install the two nuts and the bolts securing the surge tank to the fender rail.

Tighten
Tighten the surge tank nut and the bolts to 4 N·m (35 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.




3. Connect the coolant level sensor electrical connector to the surge tank.



4. Connect the outlet hose and clamp to the surge tank.
5. Refill the surge tank with coolant. Refer to Cooling System Draining and Filling .
6. Install the air cleaner outlet duct assembly.



7. Connect the two inlet hoses and clamps to the surge tank.
8. Connect the negative battery cable.

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

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