Repair 7

The thermostat in the 2006 Chevy Malibu regulates the engine temperature by allowing or restricting the flow of fluid that goes through the coolant veins inside the engine block and engine heads. At 180 degrees F, the thermostat opens and forces more fluid though the engine. This lowers the temperature in the engine to prevent overheating. At some point, the thermostat will fail. When this happens, the engine could overheat and cause thousands of dollars in damages.

Instructions

1

Remove the two bolts that secure the T-Stat housing to the right engine head. To locate the housing, follow the upper radiator hose to the engine head. The hose connects to the T-Stat housing.

2

Lift the T-Stat housing upward and remove the thermostat from the engine head.

3

Clean the old gasket off the engine head. Use a small scraper or wire brush if necessary.

4

Place the spring end of the thermostat into the engine head and then place the thermostat gasket over the thermostat.

5

Place the thermostat housing onto the gasket and bolt it into place.

The repair of your 2000 Malibu Horn is essential to the safety of your vehicle. A working horn allows other people to be aware of your presence to help avoid accidents. A working horn is also needed to pass state inspection. You will first need to purchase a replacement horn at a junkyard or used parts dealer. The repair of your horn is straightforward once youve secured a replacement part.

Instructions

1

Open the hood of your Malibu and prop it into place.

2

Locate the horn behind the grille of the vehicle.

3

Unscrew the screws holding the horn into place.

4

Unplug the power cable that is secured into the horns socket. Remove the horn from the vehicle.

5

Slide the new horn into place behind the cars grille. Screw it into place so that it is secure. Plug the cable into the horn.

6

Close the hood and clean your work area.

The 2001 Malibu cam relatively well-equipped with standard features. The mid-sized sedan came with: air conditioning, keyless entry, power door locks and a passive ignition disabling system. The passive ignition disabling system, known as Passlock, prevented the Malibu from starting without a coded key. When the Passlock system detects a fault in the security system, a "Theft System" light stays lit on the instrument cluster.

Incorrectly Coded Key

The Passlock system on the 2001 Malibu uses a key with a small magnet on it. This magnet passes a sensor inside the ignition tumbler, and the sensor reads the code stored in the magnet. If the codes do not match, due to improper coding or a failing key, the Theft System light stays on and the vehicle will not start.

Failed Ignition Tumbler

Over time, the wires inside the Passlock ignition tumbler can wear out and create a short. If the computer senses a short-to-ground in the wiring of the Passlock system, it triggers a "Security on" code that illuminates the "Theft System" light until you repair the problem.

Failed Instrument Cluster

As your 2001 Malibu ages, water and other debris can cause damage to the circuitry of the instrument cluster. If the instrument cluster shorts out, it is common for the "Theft System" light to illuminate.

Control Module Failure

The 2001 Malibus body control module and powertrain control module work together to determine when the Passlock system is to allow the car to start. When one of these two components fail or are incorrectly programmed, the "Theft System" light illuminates and the Malibu will not start.
