For 1990-2009 cars

### Removal Procedure

1. Disconnect the electrical connector from the sensor.

Caution: Before removing the low coolant probe, make sure the engine is cold and the pressure in the cooling system has been released. When removing the low coolant probe from the surge tank, use a drain pan to catch the fluid loss. Hot coolant can cause severe burns and personal injury.

2. Remove the sensor (2) from the radiator.

### Installation Procedure

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.

1. Insert the NEW sensor into the radiator.

Tighten
Tighten the sensor to 12.5 N·m (111 lb in).

2. Connect the electrical connector to the sensor.
3. Refill the engine coolant to the proper level. Refer to Fluid and Lubricant Recommendations in Maintenance and Lubrication.
